Glossary

Move Notation

Jack-O' has a complex moveset, with Held Servant stance, and the option to hit and cancel off servants. For this reason some unique notation is utilised. The below chart provides all notation that is used on the Dustloop site, alongside commonly used alternatives. For the rest of this page, move strings will rely on this notation, and it can often be invaluable for concisely describing Jack-O's complex combos and blockstrings, so it is worth familiarising.

Okizeme


Useful Links:

Okizeme is the art of attacking an opponent during their wakeup. Jack-O' is a specialist in okizeme, giving her an incredible variety of ways to completely safely pressure an opponent after her offense is complete. In contrast to Millia, Jack-O' is more about safejumps and leading into her own sandwich Pressure, with less loopable damage output

Jack-O's okizeme also comes in a huge variety from novice to impractically difficult. This page does not document them all comprehensively, and instead provides (where applicable) some easier options and some optimal options.

For the sake of brevity, the strings only list until the first mixup hit. From all aerial starters it is followed up by a dl.2K, while grounded starters except Throw may be followed up with 214K or 2D.

Safejump Hitconfirming

Off any safejump okizeme, you cannot react to whether your move hit, was blocked, or whiffed entirely. To ensure that you can both deal a combo and not be caught by reversals, you need to manually delay the follow-up hit such that if the move connects you will still perform the follow-up in time, but if you whiff you'll be holding block during that period, preventing you being punished.

The amount of time you should delay never changes, as it is entirely dependent on blockstun, hitstun, and hitstop effects. Thankfully, all okizemes can use the exact same amount of delay. No matter the okizeme or the opponent, after the opponent's wakeup you should block for the first 13 frames to avoid any invincible reversal. Not to be confused with actually blocking for 13 frames, this time includes hitstop which creates a delay before the input would be necessary if it connected.

An important mechanic is FD Block cancelling. During a 'Super Flash', you can cancel the first 3 frames of any normal attack into FD Block. Therefore, even if your attack is slightly early and begins before the super flash, you can hold FD Block to protect yourself, at the cost of minimal Tension. Delaying your input to at least Frame 17 avoids all need for FD block cancelling, but makes the input window tighter.

  • j.P Cannot true blockstring into a 2K due to landing recovery. Therefore, it is only a safejump against a wakeup reversal, it is not safe from a reversal after the first block. The latest frame you can input 2K and have it combo is Frame 17, giving at most a 4 frame input window.
  • j.K can only true blockstring if there are zero frames spent blocking, similarly due to landing recovery. The latest frame you can input 2K and have it blockstring is Frame 16, giving at most a 3 frame input window.
  • Servant Bounce Theoretically, a servant being hit by a reversal will massively delay its active time due to hitstop on the servant. This is not a problem in any given example, but some okizeme may have different timings as a result.

Fast Falling Grounded Okizeme

In all listed okizeme, there are grounded options, some hit on wakeup, some with a small delay. These always assume the use of FD Fast Falling. By using an FD Block in the air, you cancel an airdash (similar to using an attack), but also gain higher gravity, landing much faster. This is sometimes critical to getting powerful okizeme options.

For all given sequences, FD Fast Falling is used, with the notation FD FF. Not using FD Fast Fall may make some options much slower.

Meaty Timing

Sometimes an attack may land shortly after the opponent's wakeup, allowing some wakeup options. In the okizeme overviews, the timing specifies what frame of wakeup the attack lands on. If the move hits on wakeup due to a servant being bounced into the opponent, the timing instead refers to time from exiting the blockstun of the intial meaty attack

  • FN (e.g. F6), the move hits on the Nth frame after wakeup, or exiting blockstun
  • Non-meaty The move does not hit immediately, but the gap is not specified.
  • Meaty The move is active during the wakeup. If the initial okizeme is a servant, string is a true blockstring.
  • Safejump The move hits the same as meaty, but also the move is able to block reversals as a safejump.

Because of Throw Immunity, the earliest possible frame for Throws is always F6.

Throw Midscreen

Throw is Jack-O's most straightforward method of gaining a strong okizeme. It is an integral part of her pressure strings, and has good mixup opportunities. Its okizeme is not as potent as her 2D but is one of the better okizeme starters.

Throw > 236P > dl.5K > jc > IAD > dl j.H  Very Easy 
Option Meaty Inputs Notes
Overhead Crossup Meaty Throw > 236P > dl 5K > jc > IAD > dl j.H If the servant is bounced at the correct time, the IAD will be able to pass over some wakeup reversals, due to their hitstop on servants.

If the j.H is not delayed enough, the enemy will have 'crossup protection', meaning they do not need to block the crossup.

Alternatively, end in dl.214K to be safe against 6P option selects, at the loss of Command Servant Gauge.

Low Crossup ≤ F19 Throw > 236P > dl 5K > jc > IAD > FD FF > Land > 2K Extremely large gap, relies on opponent being passive of missing an attack.
Overhead Sameside F1 Throw > 236P > dl 5K > jc > IAD > 214K Won't true blockstring into the 214K, but if the initial 5K is timed precisely it can perform a 1F frametrap.
Throw ≤ F20 Throw > 236P > dl 5K > jc > IAD > FD FF > Land > 4/6D Extremely large gap, relies on opponent being passive of missing an attack.
Servant meaty into a crossup. A very easy okizeme. Even when delays are performed at incorrect timings, it should be very safe unless the opponent uses an invincible reversal. The end outcome is sandwich pressure, with a half-duration servant, making it relatively good on-block, and on hit can easily combo into a sandwich combo giving good reward.
The primary flaw of this okizeme is the necessity to use Command Servant Gauge to be safe on mixup options, and it trivially fails against GGST Leo Whitefang Icon.png Leo's Eisensturm

, which can be input regardless of a crossup. This okizeme also has very bad mixup opportunities, with only a left/right mixup, all low options are very poor.
Throw > 236[P] > TK.ws.6X > dl j.P  Easy 
Option Meaty Inputs Notes
Overhead Safejump Throw > 236[P] > TK.ws.6X > [dl j.P] or [dl j.K] The j.P must be delayed enough such that were it to connect it combos into the 2K.

j.P is much easier, but cannot true blockstring into 2K, making it still possible to lose to a reversal after being blocked.
j.K will true blockstring, but will whiff against reversal 2P and 2K attacks due to being fully crouched Frame 1.

Low Non-meaty Throw > 236[P] > TK.ws.6X > Land > 2K
Crossup Non-meaty Throw > 236[P] > 66 > TK.ws.6X > Land > 5P
Throw Non-meaty Throw > 236[P] > TK.ws.6X > Land > 4/6D
Note: Tiger Knee Throw Servant can be done by simply holding forward jump and pressing any attack button a few frames later.
Throw Servant safejump into sandwich pressure. Great pressure, no mixups. Unlike most safejumps this one creates a sandwich setup between Jack-O' and the opponent with full duration, allowing it to trivially lead into strong sandwich pressure loops, making it the best safejump on block. Its mixup options are relatively weak as they are all notably slower and lose to simple reversals like Throw, and are fuzziable, making it quite weak for securing a hit immediately.
This okizeme is notoriously clumsy to learn, even if it's not executionally very strict. It is not visually clear if the Throw Servant was performed as a Tiger Knee, which is required to not whiff, and even if you do, you must add a delay to avoid whiffing.
Throw > 236[P] > 9 jump > dl j.ws.D > dl j.S  Medium 
Option Meaty Inputs Notes
Overhead Sameside Safejump Throw > 236[P] > 9 jump > dl j.ws.D > dl j.S The servant release delay must be during the rising arc of the jump, such that as the move descends the servant will not come into contact with the j.S.

If j.S hits the servant, it will not be a safejump, but does open new combo routes on hit. j.P is easier, but much lower reward.

Low Sameside Non-meaty Throw > 236[P] > 9 jump > dl j.ws.D > Land > 2K
Overhead Crossup Safejump Throw > 236[P] > 66.9 jump > dl j.ws.D > dl j.S Due to the tight amount of time, the crossup variant is significantly harder to perform as a safejump compared to the sameside.
Low Crossup Non-meaty Throw > 236[P] > 66.9 jump > dl j.ws.D > Land > 2K
Throw Non-meaty Throw > 236[P] > 9 jump > dl j.ws.D > Land > 4/6D
Jumping Release Servant safejump with left-right mixup. Good mixups, less pressure. Very difficult timings makes it extremely unreliable to perform as a true safejump and meaty, but works fairly well despite these. On block, the servant will land on the same side as Jack-O', giving weaker follow-up pressure on-block. However, its crossup--while slightly telegraphed--is safe, making it a viable mixup tool, furthermore the use of j.S allows much more punishing combos for hit, especially Counter Hit.
Though this mixup works well even if performed incorrectly (due to most reversals requiring a directional input), getting the safejump with meaty requires 1 link and 2 unbufferable timings, making it particularly difficult to learn correctly.
Throw > 236[P] > 66.9 jump > j.ws.D > j.S& > Land > 2K  Medium 
Option Meaty Inputs Notes
Sameside Mid → Crossup Low Safejump Throw > 236[P] > 66.9 jump > j.ws.D > j.S& > Land > 2K
Sameside Mid → Crossup Overhead Safejump Throw > 236[P] > 66.9 jump > j.ws.D > j.S& > j.H
Note: The servant must be hit such that it will cause a sameside okizeme before Jack-O' falls behind the opponent.
By performing a timing incorrectly the game's throw protection will nullify this sequence entirely, as the first hit will be blockable from either direction.
Sameside-Crossup sequence safejump. A strong knowledge check. A bizarre variant of safejump, by enforcing the enemy to wakeup facing sameside their only reversal options will whiff Jack-O'. It leads into a sandwich pressure with a half-duration servant, giving less reward on block. Its primary strength is in the visual ambiguity, being extremely deceiving about the sequence which must be blocked sameside then crossup, it can easily confuse opponents. Even after solving this, the safejump comes with a natural high-low mixup which cannot be option selected, but can be fuzzied.

Throw Corner

A lot of corner pressure enables Throws to make corner okizeme achievable. It is often much safer than midscreen, especially leading into powerful corner pressure, however it also disables the option for left-right mixups.

Basic Servant Set
Throw > 236P > (microwalk back or microdash forward) c.S > 2D/5D& 
Option Meaty Inputs Notes
Low Meaty Throw > 236P > 5P* > (microwalk back or microdash forward) c.S > 2D Movement is not important here however helps keep it looking the same as the overhead option
Overhead Meaty Throw > 236P > 5P* > (microwalk back or microdash forward) c.S > 5D& Microwalk back vs regular block; Microdash forward vs FD. Can combo after servant hit with 5K > 6H for wallbreak
Throw Meaty Throw > 236P > 5P* > (microwalk back or microdash forward) c.S > 66 4D/6D Can be good once opponent starts to respect the mixup

Really basic option that gives you High/Low/Throw while beating reversals. The only problem with this is FD causes too much push back making it difficult to be sure what will work

Servant Throw Bounce Safejump
Throw > 236[P] > TK.ws.6X > Land > 2K  
Option Meaty Inputs Notes
Low Safejump Throw > 236[P] > TK.ws.6X > Land > 2K
Overhead Safejump Throw > 236[P] > TK.ws.6X > j.P Unreactable, fuzziable against the Low, lower damage.
Delay overhead Meaty Throw > 236[P] > TK.ws.6X > dl AD > j.S Reactable, unfuzziable against the Low, higher damage.
Throw 6F Throw > 236[P] > TK.ws.6X > Land > dl 4D/6D

An executionally easy safejump with an extremely strong high/low mixup. The thrown servant falls on top of the opponent during wakeup, meaning they will always be hit meaty. The follow-up 2K does not hit the servant, this means the mixup leads into a blockstring with a full duration servant, allowing easy corner pressure. This is generally the best option for corner okizeme, due to its versatility.

Sweep

Sweep (2D) is Jack-O's primary okizeme tool, with huge frame advantage and the option to OTG it opens up many possibilities, and is usually the main goal of Jack-O'. An interesting property of Sweep okizeme is any move that hits or confirms into 2K can immediately combo into 2D to restart the okizeme, sometimes using the additional summon to deal more damage on the second loop, though this loses the combo potential of the first okizeme, and gives more probability of failure.

Sweep
2D, 236[P] > ws.6X, 2K 
Option Meaty Inputs Notes
Low Meaty 2D, 236[P] > ws.6X, 2K Alternatively, back away from the opponent and meaty with 214K to be safer from reversals, at the loss of resources and pressure.
Overhead ≤ F6 2D, 236[P] > ws.6X, 5[D] Due to how Dust works, it can defeat Frame 6 abares.
Throw F6 2D, 236[P] > ws.6X > dl 4/6D
Less an okizeme and more a setup. With the opponent knocked down, you can safely summon a servant and prepare it on the other side, leading directly into strong sandwich pressure.
This okizeme offers almost no mixup opportunities, and carries with it the risks of opponents' invincible reversals. The overhead is powerful, but can be reacted to and is unsafe when blocked. However, the setup is also quite easy to do and gives perfectly adequate damage if the opponent does not escape the pressure created.
Servant Drop Safejump with Fake-Out
2D > 236[P] > 9 jump > j.ws.D > dl.ABD > dl.j.H 
Option Meaty Inputs Notes
Overhead Crossup Safejump 2D > 236[P] > 9 jump > j.ws.D > dl.ABD > dl.j.H Delay the Air Backdash until after crossing past the opponent, therefore not going past them, instead only stalling in the air for a few frames.

The backdash is not needed if the jump is delayed, but it introduces a feint sound to confuse reactions, and avoids telegraphing the option.

Low Crossup Meaty 2D > 236[P] > 9 jump > j.ws.D > Land > 2K
Overhead Sameside Safejump 2D > 236[P] > 9 jump > j.ws.D > ABD > dl.j.S Can be a safejump but the inputs must be performed extremely quickly, usually requiring releasing the servant before the peak of the jump.

being performed on wakeup without the tight safejump timings, at the cost of the attack no longer being meaty.
Low Sameside Meaty 2D > 236[P] > 8 jump > j.ws.D > Land > 2K Telegraphed by a slightly different jump trajectory, but avoids being fuzziable.

From further away a 9 jump can be used, and still remain sameside.

Throw Non-meaty Throw > 236[P] > 9 jump > dl.j.ws.D > Land > 4/6D
Note: From further away it becomes nessecary to perform a micro dash before the jump. For ABD varients this makes the entire sequence near frame-perfect, but can be performed from almost any distance.

A popular and somewhat lenient okizeme, the overhead options have lenient timings and the confusing left-right motions disrupt opponents. It allows a four-way mixup plus Throw, but only one option is easily made a safejump without very tight execution. On samesides it will lead into sandwich pressure, but not on crossups, however the servant will be at full duration providing good follow-up pressure.

Throw 6F 2D > 236P > c.S& OTG > 8 jc > IAD > FD Fast Fall > Land > dl.4/6D Can be done from crossup but needs a run-up first.
Note: 2D must land at close-range such that Jack-O' will perform a c.S. Adding a microdash after the servant summon can slightly extend this range, but is quite precise.

A fairly potent mixup plus Throw, with the overhead left-right mixup being fairly low execution, making it excellent for securing an attack in offense, only held back by its requirement to be close range and the ability to be 6P'd by the opponent. Due to the issues of 6P from the opponent, using j.S instead of j.H can help avoid wiffing or getting counter hit in certain situations. Also deals 39 extra damage via the OTG attack. When performed as a crossup, leads into sandwich pressure, and all outcomes provide a half-duration servant, making sameside options particularly mediocre on block, but this block is also much less likely to happen.

Other


Jack-O' has several other ways of achieving a knockdown, be it from stray 6Ps or from combos. These rarely allow elaborately strong okizeme but are still useful to identify for maintaining pressure or even as a way to create resets.

2H Safejump Reset (Kazunoko Safejump)
... > 2H > 236[P] > delay > 9 jump > dl.AD > j.ws.D > dl.j.P 
Option Meaty Inputs Notes
Overhead Safejump ... > 2H > 236[P] > delay > 9 jump > dl.AD > j.ws.D > [dl.j.P] or [dl.j.K] j.P is much easier, but cannot true blockstring into 2K, making it still possible to lose to a reversal after being blocked.
j.K will true blockstring, but will whiff against reversal 2P and 2K attacks due to being fully crouched Frame 1.
Low Meaty ... > 2H > 236[P] > delay > 9 jump > dl.AD > j.ws.D > Land > 2K Delay jump timing slightly less than the overhead safejump.
Some long combo strings make it impossible to hit meaty, even with no delay.
Throw 6F ... > 2H > 236[P] > delay > 9 jump > dl.AD > j.ws.D > Land > 4/6D Delay jump timing slightly less than the overhead safejump.
Note: The delay before jumping is dependent on the combo used into this. The lengthier a combo the less delay must be used.

By ending a combo early with a 2H, it becomes possible to reset into a safejump, with the option for a high-low and Throw mixup. This usually comes at the cost of losing a potential wallbreak for better damage, Positive bonus, and recovering any spare servants to regain gauge. It will usually leave Jack-O' on a pressure string with no servants and minimal gauge, making it not very strong as a pressure option, unless coordinated with a combo to land near to a servant.

With the reversal-safe reset it can be potentially quite punishing, especially if it manages to corner carry and enables Jack-O' to begin corner pressure, which is a far bigger reward than a wallbreak. The variable and tight timing is problematic, making it extremely difficult to do a meaty safejump successfully, meaning usually either some abares or a fast invincible reversal will succeed.

Note: Distance dependent. At some ranges the crossup variations may hit sameside, and sameside variations will not reach.

A potent safejump mixup off Counter Hit 6P giving substantial reward off grounded 6P attacks. Should be noted that Jack-O' can already combo off anti-air 6P CH and so should not use this.

The primary weakness is Fuzzy Blocking, therefore if you wish to make moves unfuzziable you should delay any options to land on the same frame as mixup options you wish to use, or you should exclude options that are fuzziable if this is a risk (note even if something is fuzziable it is practical to use it).

Sandwich Pressure


Useful links:

A simple sandwich position

Sandwich Pressure is a position of advantage when the opponent has a servant behind them and Jack-O' is in range to use her grounded normals. The "Sandwich" creates a position such that Jack-O' can indefinitely loop pressure , while remaining completely safe, and locking the opponent in place.

Sandwich pressure often builds an incredible amount of RISC, while enforcing an oppressively strong Strike-Throw threat, as every blocked hit could be mixed up with a throw. FD blocks are also less effective, as the pushback of the Attack Command will repeatedly move them closer to Jack-O'.

Despite being usually an extremely lengthy series of frametraps, it can also be extremely reversal safe. If you intentionally speed up the string you can form true blockstrings, making it impossible to reversal, however they are still required to block lows if you use 2K or 2D, easily checking if they attempted a motion input.

Generally speaking, every hit in the pressure string can be one of the following:

  • Frametrap
  • True Blockstring (especially lows)
  • Throw mixup
  • Overhead mixup

Additionally, strikes have the option of either being one that can hit the servant, or whiff the servant. These will alter the routes of the pressure string.

This can be quite modular and adaptive. Later we discuss a few strings to help introduce the basics and how these can be applied.

    Frametrap into an airborne position. Can only work as pressure with a followed up 214K, leading into an unreactable high-low mixup with j.S and 2K, with meterless conversions on hit. Because it requires a jump cancel, it can only be done as a Frame 3 frametrap off c.S, Frame 4 when linked off 214K, and Frame 8 off 5K. Can true blockstring from c.S&, 5K&, and a meaty 214K (i.e. the servant was far away from the opponent).
  • Jump Cancel A slow but safe overhead and crossup. Possible from 5K and c.S. From c.S& it can catch backdashes and is likely to cause a whiff punish against most reversals, including invincible moves, only commonly losing to 6P. This is especially good if there is also a sameside servant, so she can either perform a sandwich combo or return to a sandwich pressure if blocked.
  • BRC Instant Overhead (See: Instant Overhead) A fast overhead which can be safely used after Attack Command (214K). Technically more reactable than an Uncharged Dust (5D), but is much rarer, and telegraphed from a backdash, therefore less easy to anticipate. It is also safe on block, unlike Uncharged Dust.

Sandwich String Examples

This section presents some simple pressure loops, to help demonstrate how these tools can be applied. This is not an exhaustive list, for thos, but an introduction to the utilities of sandwich pressure strings. This will also discuss flaws in the strings, to better show the reasons to use different strings.

Note: The parts of the strings in square parenthesis "[]" are the looped sections, anything in round parenthesis "()" are optional but may improve the string.

(2K > 2D > 214K, 66.c.S&)

Simple true blockstring. So long as the servant is available and the 2K is correctly linked this can loop into itself as a true blockstring. The 214K and c.S& presents mixup opportunities by going into a Throw, Charged Dust (5[D]), or 2K. Even when the servant is gone, the c.S keeps safe mixup options available into safe string enders. If the enemy attempts to reversal any time, they're liable to be hit by the 2K and 2D as a true blockstring, and by delaying any one of these inputs you can create a frametrap on any hit.
Unfortunately, this string has very little true mixups, as Throws can be fuzzy-blocked, and 5[D] is reactable. It is still a threat, but can be realistically defeated. Additionally it has some weakness to Faultless Defense, and will require the initial 2K to be point-blank to not eventually leave a gap. This is because 2D will hit later if there is distance to travel, and the c.S& is affected by how long you need to run for.

2D > 214K > f.S > [5H > 214K > (66.)f.S&]

Anti-Faultless Defense string. There is little to no mixup opportunities if the opponent is holding FD block. However, it will keep them in repeated frametraps, while dealing immense Tension damage (approx. 27% per loop), and if they drop the FD block you can begin to perform a mixup off 214K, creating a dangerous decision for them.
If they hold FD the entire time, the gap will invariably be too large to safely set up any Throw or overhead attack, and the moves will begin to leave gaps, making it open to invincible reversals, and eventually lose the pressure. This can be extended by dashing before the f.S, but is very precise. However, by dealing so much Tension damage they may lose the opportunity to use any invincible Overdrive, and meterless invincible reversals will whiff off anything except to catch the 5H, limiting their options down massively.

c.S& > 236236H > 5P > [(dl.)214K > 236K]

Chip damage string. By using Cheer Servant On H, the servant can be prolonged for an extremely long time and by using only specials, this can do an incredible amount of damage and easily maxes out the R.I.S.C Gauge. It has no mixup, but it also doesn't need to, as the enemy is incapable of escaping and will take as much as a full combo in chip damage regardless. Because of the likelihood of Max R.I.S.C., you can also use an uncharged Dust (5D) and get an automatic counter hit if it hits, allowing immediate conversion into a Forever Elysion Driver (632146P) if you have Tension to spare.
The big flaw is its weakness to FD blocks, which not only prevents the chip damage and R.I.S.C., but manages to take less Tension damage than the previously discussed anti-Faultess Defense string. Additionally, you can only do up to 3 236K before you'll whiff, meaning you must break the blockstring to run back up. This is a game of prediction and reaction, as you could run up after the 1st, 2nd, or 3rd loop. You could also convert it into better anti-FD block (i.e. (f.S > 5H > 214K)) moves while still in a true blockstring, forcing the opponent to be reactive to your string.

Sandwich Enders

Also see: Block-String Escapes

Eventually the sandwich will end if you do not land a hit or Throw. Jack-O' is naturally a dangerous character to end a string with, so it's worth understanding her unique options, beyond her standard selection.

Summon cancelling off a blocked c.S& is +7, this makes it one of the safest ways to leave any blockstring. However, doing this sacrifices all mixup potential you have from c.S&. This depends on how valuable the mixup is, and how your Tension compares (e.g. if the opponent has 100% Tension, they can reversal Overdrive safely) and how your Health compares (e.g. if you're one hit from losing the round, it's a big risk).

Naturally, ending on any Dust (5D or 5[D]) attack is extremely poor when blocked, as you will either be extremely negative or must commit to a Roman Cancel. Similarly, Throw is extremely vulnerable to punish, making it important to use a PRC Option Select if the punish is a major risk.

With more plain options, f.S, 5H, and Servant Shoot (236K) all make good enders, as they can summon cancel and be relatively safe due to their pushback. 2d is significantly worse as an ender due to its substantially lower blockstun, but can hit at a good range and does threaten a Low attack.

Sandwich Strategy

Strategically, one must balance a few factors, and it is complex enough that no singular answer exists, there will always be exceptions and edge-cases to consider.

If the servant has already been hit or on the field for more than a few seconds, your pressure strings will be much shorter. In these cases you need to consider the value in hitting the servant at all. It might be be worthwhile to utilise Cheer Servant On H to simply keep it active if its position already enables a longer string. Conversely you can end with a shorter string, giving less total pressure. You should be very careful to not allow the servant to leave when you input Attack Command, as this allows the opponent to massively punish you. You are also limited by Servant Gauge and if you run out then your final attack may be unsafe as you have no summon cancels (See: Block-String Escapes). Resetting the string with normals can be beneficial to be economical, especially given you can recharge gauge if you have not used Attack Command (214K in the last 60 frames.

You also need to be mindful of the servant's position. If it falls in front of the opponent, the sandwich automatically ends, meaning some moves may fail to keep the string going based solely on positioning. However, you can still use this opportunity for a mixup or a safe exit, with the power of a final c.S& or similar move.

Stable sandwich pressure is best thought as an adaptable and situationally changing pressure, with a large number of approaches that can dynamically switch between each-other, especially using the 214K as an easy transition:

  • If your opponent uses Faultless Defense, you can punish them with safe string extenders that deal lots of Tension damage.
  • If your opponent is prone to using reversals you can rely on true blockstring lows to catch their input buffers.
  • If your opponent is prone to jumping out or using jabs, you can set up many frametraps easily.
  • If your opponent is low health, you can force chip damage to break them down.
  • If your opponent is over-respecting the pressure, you can mixup into Charged Dust (5[D]) and Throw.

Sandwich pressure is a diverse, creative set of options. It's a foundational part of Jack-O's gameplan due to the extremely advantageous position and allows her complete control on the situation. It's also a good opportunity for experimentation, due to how variable it can get, giving a lot of freedom in your approach to a situation, and the amount of complexity you put into your use of the strategy.

Corner Pressure


Jack-O's corner pressure is one of the most powerful and diverse positions of any character. With the right execution, she has access to indefinite pressure, with high-low mixups, chip damage strings, unblockable combos, and more.

Pressure conditions

Some of Jack-O's routes require certain conditions to be met to be used, or are improved by including them. As Jack-O' is very set-up and resource focused a lot of the neutral play and mid-screen pressure should look towards these as an objective. Some routes also fulfill this conditions for further pressure.

  • Dash Momentum
Some routes are much stronger with dash momentum leading into it, namely 2S routes and the spacing-dependent Servant Shoot pressure loop. This can also help overcome potential whiffs created by Faultless Defense. This is usually obtained by making the opponent block Attack Command, using the +15 on-block frame data to give time to run up and still land an attack safely.
  • Active Servant
A servant must be placed nearby, though preferably not directly on top of the opponent, so as to allow cancel options to strike it while being pushed back from the opponent's block. Without this, there are almost no reliable or threatening pressure options. Though most routes only require 1 servant, the critical requirement is to not whiff the servant, therefore having 2 might allow more coverage against amounts of pushback (i.e. Instant Block and Faultless Defense). Additionally more servants improves chip damage and Tension gain slightly. Thankfully, there are ways to spend Tension or perform okizeme (See: Okizeme) to prepare a servant if one is not available.
  • Servant Gauge
All of Jack-O's options are influenced by the availability of her Command and Summon Servant Gauges. Each route offers an amount of gain or loss on each type of gauge, so options can often be balanced to reflect what resources you have and need. Generally, you requiure Command Gauge to use Attack Command, this offers safe frametraps to change routes, and allow easy resets even against heavy pushback. If you have no gauge, your options are very weak, and even with Tension it is difficult to delay a string long enough to generate more gauge--though it is doable.
  • R.I.S.C. and Tension
It is important if the opponent is at a high R.I.S.C. and/or has not got substantial Tension. R.I.S.C. largely increases the reward for a successful strike but also massively enhances the value of Cheer Servant On H, where 100% R.I.S.C. enables Uncharged Dust combos. The opponent using YRC is a natural deterrant and counteracts all meterred choices, and it is very rewarding to apply pressure when the enemy is below 50% Tension.

Corner Pressure Routes

Below is discussed Jack-O's primary routing for corner pressure. Generally, this covers most practical and useful options. However, corner pressure may always need to adapt based on how it started for cancels and gatlings and servant positionings. These routes can each be complicated in functionality due to unique nature of Jack-O' often allowing unusual counterplay: but this does not reflect the difficulty in applying them.


... > 236P~PRC > 2K& > 2D > 214K > Dash > c.S   Easy
Requirements: 50% Tension, 1 bar of Command Gauge
Summon PRC. Off any attack you can cancel into 236P~PRC to get a servant ready at the cost of Tension. This is extremely useful as it allows Jack-O' to force optimal corner pressure even without any prior setup. Due to the slowdown effect, most fast moves will frametrap against anything reacting after the PRC, meanwhile if the opponent input before the PRC it will allow you to see if they used a reversal and use most effective punish. Unfortunately you cannot true blockstring, meaning you are always guessing if the opponent intends to use an invincible move or not.
Even when cancelled off Lv. 4 movesThis includes 5H, 2H, and 6H(1), a Drift PRC into c.S can always be Thrown on reaction, making it not particularly useful. As a result you will need to use 1 bar of Command Gauge to reset into the c.S.
If the opponent FD blocks and you cancel off f.S, 5H, 2H, 6P, or 236K, you will whiff 2K and should instead only use 2D, this can be easily done on reaction. Drift PRC is still throwable on reaction as it drifts very far,


236K& > 236[P] > 236K* > hs.6X > Dash > c.S   Hard
Requirements: Servant, 1 bar of Summon Gauge
Servant Shoot pressure loops. A series of frametraps resetting into pressure with a servant available, allowing it chain into itself indefinitely. Primarily useful for resource management, as you can generate a lot of R.I.S.C., Tension, Command Gauge, and reset the servant's duration, allowing you to go into other options very easily. However, the string is interruptible and provides little to no mixups. The routing is very complex, but overall incredibly favorable.
While there are two gaps, discussed below, each is heavily altered by distance. If the second 236K occurs very close, the first gap can be defeated by a 5P without trading, in exchange it will catch an opponent trying to jump out, this massively weakens the first gap but does strengthen the second gap. From too far away it becomes impossible to enforce a dash-up reset, but the pressure remains mostly unaffected. Starters like c.S > 2H and f.S > 5H reach a good position, however if c.S > 2H is crouch blocked it will remain in 5P range, while f.S > 5H will go very far on Faultless Defense. If the opponent is using Faultless Defense, then simply using only f.S will give an appropriate distance (c.S also works, but fails if they don't Faultless Defense), but this is difficult to confirm and on normal block leaves you within 5P range, making it somewhat read-based.
The first gap is from 236K& > 236[P] > 236K&, giving an 8F frametrap, however this can be spaced in such a way most frame 7 moves cannot hit Jack-O' before the 236K becomes active, usually trading rather than punishing. With 236K counter hit launching the opponent, these trades leave Jack-O' advantageous, albeit without a servant. If there is enough spacing, Jack-O' can instead replace the 236K* with Release Servant, causing the enemy to whiff and allow a whiff punish. If she's within 5P range, her only true callout is to walk backwards out of range (she has time to do so) then use Attack Command, or in some very select cases (e.g. GGST Ky Kiske Icon.png Ky's Stun Dipper

), to jump over it. On the upside, from too close, an opponent jumping out will be forced to block the Servant Shoot, preventing any jump-outs from the second gap.
The second gap is from 236K* > hs.6X. Any opponent can crouch to massively delay when the servant will hit, however standing opponents (Except GGST Giovanna Icon.png Giovanna) can be caught in a frametrap, or even a true blockstring if they're particularly tall. Even crouching opponents may have very limited options for abare if Jack-O' is out of range, but this is extremely matchup dependent. Universally, every opponent can crouch block into a 6P. Even on whiff, 6P will hit the servant, allowing cancel options to give them a significant opportunity for escape. Again, replacing the Throw Servant with either Release Servant (leaving you +10~12 based on spacing) or a fast Attack Command allows catching this option, at either the loss of allowing a jump-out, or at the cost of Servant Gauge. From Release Servant, you can easily catch fast abares (even GGST Sol Badguy Icon.png Sol's 5K

, as 2H is a disjoint) with 2H and 2D, where 2D is a safer frametrap at point-blank, but 2H allows resetting the loop for free on-block, but their 6P should also always lose to a Dash c.S. If an enemy jumped out after the first gap earlier, using Throw Servant or Attack Command with the held servant can usually catch them if you're fast enough, however it will reliably defeat meterless frametraps against a 6P. Generally, this position is extremely favorable, as the opponent has very few reliable options, many come with more risk than they do reward, and your options maintain Jack-O's pressure easily. It's worth noting if the opponent does block this, their position affects the reset. If they stand block, some tall characters cannot be put into a true blockstring from hs.6X > Dash > c.S, while it is a frametrap it allows an invincible reversal. In these cases, your only true blockstring to reset the loop is hs.6X, f.S > 5H, but this provides less routing options. If they are using Faultless Defense, you can also reset the loop with a dash up f.S as discussed earlier.
The full loop, including a starting 2H, provides 4500 R.I.S.C. (approx. 35%), 1900 Tension (19%), and 109 frames (0.44 ~ 0.88 bars) of Command Gauge, giving it a very good reward if the opponent fully blocks the string. This is substantially better than other possible loops in almost all resources. Due to the massive matchup variability and complexity of this one route, further matchup-specific information is given later in the section.


... > 236236H > [5K > 2D > 214K > Dash]×N    Medium
Requirements: Servant, 50% Tension, 1+ bars of Command Gauge
Cheer H Loops. At the cost of Tension, Jack-O' can force an extreme amount of chip damage and generate high R.I.S.C., completely safely. This allows some of the most aggressive pressure in the game.
There are two primary loop strings. c.S > 236K > 214K > Dash is optimal, giving the most chip damage, R.I.S.C. gain, and is faster, making it harder to predict mixup timings. Unfortunately, this is pushed out by Faultless Defense after one loop. If this happens, you can on-reaction replace it with a different loop, 5K > 2D > 214K > Dash. This is weaker as it loses fast Throw mixups, but it cannot fail to Faultless Defense, and can rotate back into the former loop if the opponent stops using Faultless Defense.
Aside from the obvious innumerable frametrap opportunities, you can also trivially go into a Throw after every c.S and 214K. If the opponent's R.I.S.C. reaches maximum—and it very easily can—then 5K and c.S can gatling into a Uncharged Dust (5D), which on-hit allows a high damage, meterless wallbreak combo, because any hit gives the Large Counter Hit. c.S can also safely gatling into 2D for surprise lows, to stop an opponent pre-emptively stand-blocking after every c.S. Unfortunately, the Uncharged Dust can never be in a true blockstring, so the opponent will always have some opportunity to use an invincible reversal, particularly as the string will generate a lot of Tension for them. Because the Uncharged Dust can only combo from max R.I.S.C., the opportunities for mixups increases the more R.I.S.C. the enemy has already accumulated, and reduced (or even prevented entirely) the more meter the opponent spends on Faultless Defense. If you true blockstring consistently, the opponent can trivially alternate back-and-forth to randomly Instant Block a lot of the string, this largely reduces the chip damage, but not the R.I.S.C.. It can be defeated by manually allowing delays, and with some attacks you can offset the timing without even opening up a gap, but this is very difficult; generally leaving gaps will allow the opponent to be caught unexpectedly.
From Lv. 4 movesThis includes 5H, 2H, and 6H(1) a 5K acts as a 4F frametrap to begin the string, however this leaves you open to an opponent using an invincible reversal to defeat the setup, wasting the Tension spent. If you cancel off a servant, it becomes barely possible to make a true blockstring with tight execution, meaning the opponent is forced to sustain the full chip damage or meter loss. This is most easily done with 236K, giving an optimal starter of ... > 236K& > 236236H > 2P > 214K > ... . This will fail against Faultless Defense unless the 236K& is performed at point-blank range.


c.S > 2S& > 632146P > (Servant hit) > ...    Very Hard
Requirements: Dash momentum, 100% Tension
Servant Unblockable. (See also: Unblockable Damage) Extremely finnicky to pull off as it needs a lot of things to work correctly. The timing is also very fast and strict. However, if performed correctly, the servant will bounce into the opponent while they attempt to escape the command grab, giving you time to PRC and combo into a wallbreak, for a completely unblockable combo. The only escape is to use an invincible Overdrive or Gold Burst on reaction to the Overdrive. In contrast to the Cheer H Loops, this one has higher damage output and does not require Servant Gauge, making it a more potent round-ender, however it is much more niche in its setup.
If you lack dash momentum, or the opponent uses Faultless Defense, the 2S will whiff the opponent, this can be fuzzy jumped or abared out of safely.
Because this is telegraphed by the 2S&, an opponent can pre-emptively jump to avoid the unblockable. However, this will lose to a frametrap with c.S > 2S& > 236K. This is going to be low reward in this position, but can be comboed with the remaining Tension. While a strike-throw mixup does exist off 2S& using Whiff Pick Up cancelling, it offers no advantage to other routes.
On defense, if there is no invincible reversal available, the best option is to backdash, as this is the only outcome that absolutely forces using 100% Tension.


c.S > [2D] or [f.S > 5H] > (236K) > 236[P]   Very Easy
Requirements: None
Basic blockstring and cancels. Unfortunately, without servants, there is very little pressure Jack-O' can do. At bestshe has the universal mixup options of Throw and Charged Dust off c.S. The 2D is generally unsafe, depending on matchup (See also: Block-String Escapes). The safest option is c.S > f.S > 5H > 236[P], potentially mixing in a 5H > 236K frametrap, but this string is minimal threat to the opponent. If you're slightly short on Tension, you can use c.S > f.S > 5H > dl 236K to lead into the Summon PRC route. If you have a servant already, it's probably best to instead rely on her Servant Shoot pressure loops.
One very risky option is to cancel any part of the string c.S > f.S > 5H > dl 236K into 236P > 5P& as a reset with a servant, as a meterless entry into the Servant Shoot pressure loop. This is 29 frames, making it very reactable, but potentially able to work on an opponent focused on potential frametraps.

Strategy

Overall Jack-O's strategy hinges on having a servant placed nearby. Without it, she has almost no worthwhile corner pressure, and all of her strings are risky. While Jack-O' can summon a servant off a normal, it is still very slow. Using meter to set up a servant is good, but it also inhibits Cheer H pressure and access to the Unblockable. Jack-O' either needs to take risks or expend valuable Tension to enforce her pressure. Sometimes, it can be better to simply return to mid-screen and try again; the opponent is still in a corner, it is on them to escape it.

When a servant is ready, the Servant Shoot pressure loop is easily her best pressure option overall. It provides huge resource gains, and the opponent has to make risky commitments to escape. The longer it goes on, the easier Cheer Servant On H becomes to set up, and the more powerful its threat will become as the heightened R.I.S.C. will allow earlier Uncharged Dust combos. It's worth remembering that even though she can loop it indefinitely, nothing stops her going for a sudden Throw, 2D, or even Charged Dust at various points in the loop. While this does give the enemy some Tension too, it's not even comparable to the amount Jack-O' can generate for herself.

While Cheer H provides a huge threat, you must consider your opponent's Tension. Even if you do manage a true blockstring into Cheer Servant On H, it only takes a single YRC to entirely cancel out your pressure: not only nullifying your threat but also likely putting you at risk and entirely wasting your Tension. This is almost impossible to call out due to the sheer quantity of attacks in the string. For this reason, Cheer H is generally best used when the opponent cannot already YRC out of the situation. If they're saving their meter, it can be difficult to force extended pressure, however they won't be FD blocking, allowing the more optimal c.S > 236K > 214K > Dash loop. Additionally, you can end the string early with the usual c.S mixups, preventing a late YRC escape.

The unblockable is hugely situational and probably not particularly important. Against anyone except GGST Zato-1 Icon.png Zato, GGST Chipp Zanuff Icon.png Chipp, and GGST Happy Chaos Icon.png Chaos you cannot use it unless they have below 50% Tension, otherwise they will be able to use an invincible Overdrive to escape. Regardless of matchup, they also must not have Burst. However, unlike Cheer H, it cannot be reacted out of once it begins, and if the damage is round-winning it can be a good way to convert 100% Tension into a completely secured victory. An opponent can jump out on reaction to the 2S& within 24 frames of the first startup, but predicting and/or seeing this is likely to be extremely difficult. The other problem is Faultless Defense, making it whiff which can either lose to a predictive call-out, or late fuzzying an option on the off-chance you cancelled into 2S. In most cases, Cheer H is simply the safer, better option, but if the unblockable could end the round it adds even more firepower to your pressure.

Counter Strategy

If Jack-O' lacks a servant her pressure is inherently quite weak. Aside from the standard Low, Throw, or Charged Dust off c.S it is important to watch for Summon Servant (Set)

which is always unsafe. From there, she simply wishes to not be punished for the extension (See: Block String Escapes).
Meterred pressure

The most powerful option for defeating Jack-O's meterred pressure is the use of YRC after any meterred option. Summon PRC and Cheer H both require Jack-O' to spend meter, which can be immediately nullified by the use of YRC. Furthermore, her strings usually place her very close allowing an easy strike-throw mixup off the YRC. Given that's the case it is incredibly strong defensively to hold onto at least 50% Tension as there is very little Jack-O' can do to utilise her own meter effectively without being forced to at least remove your own first. To this end, while it can be useful to Faultless Defense, losing access to YRC is a major loss.

If you are stuck in a Cheer H loop and lack the YRC to escape, one of your best defensive tools is to Instant Block repeatedly. If the pressure is gapless there is no risk to this, and if you do it correctly you massively reduce not only the chip damage but also generate Tension and enable IBFDs to largely disrupt an unsuspecting player. Regardless, your biggest threat is Strike-Throw; you can learn a rhythmn to fuzzying her pressure or simply abare once she opens a gap. Once you hit 100% R.I.S.C. the Uncharged Dust becomes the biggest threat: you can pre-emptively fuzzy a stand block after 5K and c.S, as 2D is 9 frames faster when point-blank. If you have a meterless invincible, it is worth knowing Uncharged Dust will always leave a gap. Once again, the use of Instant Block makes it difficult to make this unfuzziable. You are ultimately extremely vulnerable in this position, even if she doesn't vary the pressure rhythmn or leave gaps. Your best defense is to avoid it even starting to begin with.

Servant Shoot pressure loop

When pushed into the looping Servant Shoot pressure, every character has a unique situation, some matchups are much stronger than others; where GGST Ky Kiske Icon.png Ky can break out with ease, GGST Goldlewis Dickinson Icon.png Goldlewis requires advanced awareness to not be looped infinitely. The pressure is long, don't get hasty and try to be aware of when she presents gaps.

Some abare options become open only if Jack-O' is close or far enough, sometimes this can be caused by just crouch or stand blocking for different pushback, but can be largely increased by Faultless Defense and Instant Block. If she is using an opener to avoid the reduction from crouch block, you can use Faultless Defense to try and cause her to whiff her own servant. Any 7F or faster move if too far away will trade, but almost everyone has a preferable alternative (see below).

From the second gap, you will need to crouch block. If you do not, you will be stuck standing and therefore block the Throw Servant much earlier, usually locking you into a safe reset (and will true blockstring, in the case of taller characters). Universally, any character can hit the servant with 6P and catch most resets, but will be caught by Jack-O's 2D, therefore other options are usually safer (see below).

You may also choose to jump the 236K*. If Jack-O' continues her pressure as normal you will usually be able to use some air movement (particularly off superjumps) to reset to neutral. However, you are still vulnerable, Jack-O' can pressure your descent, especially if you can't get very far away, however, you will be out of the corner and back to a midscreen where Jack-O' will not have servants. If Jack-O' is expecting this, she may alter her route to lock you into the corner, therefore safely resetting.

The below chart summarises the available options for every character. "Close" assumes the distance created by Dash > c.S > 2H when crouch blocked, while "Far" assumes this was stand blocked: closer or further respectively should still work as expected. "Very close" assumes an extremely low pushback opener like f.S or if the opener is Instant Blocked; "Very Far" assumes the use of Faultless Defense". An "indirect" punish means that the attack continues and punishes follow-ups but theoretically Jack-O' can avoid the attack if she does not continue.

Defense and blockstrings

Block-String Escapes

When Jack-O' is blocked from any unsafe move--which make up the majority of her kit--she is usually given a variety options to escape from being punished. When all are taken into account Jack-O' has the most complex options of escaping punish, which can be hugely difficult for her opponents. It is impossible to be completely safe, but by using a variety of these options you can make it extremely hard to challenge her repeatedly poking the enemy, especially when options are chosen based on their available tools and current habits. It is not necessary or even practical to use all of these within a game, but knowing a few of them is invaluable.

Every option depends heavily upon her having Servant Gauge available, so it is important to understand that this safety comes at a cost, and the Servant Gauge should dictate when you will utilize unsafe normals that will need to be cancelled.

  • Note that 2D > 236K; 2D >236P; and 2D by itself can all be punished by invincible reversals. To stop this you will need a servant already out or calling out the reversal with 236[P] > ws.S. This is an issue with 2D and highly skilled players who are aware of the matchup will abuse this.
The core escape option. Summon Servant Hold cancelling is incredibly safe from all normals. The primary issue is you can no longer block, so we follow this up with a variety of options. Due to the framedata, you will also no longer be Counter Hit punishable at all, and if you escape successfully you have a prepared summon to restart pressure in neutral. Put simply, the enemy is now forced to catch your retreat on a read, they cannot react to your movements fast enough to make it a punish.

Escape Routes

... > 236K > ...
Servant Shoot special cancel. Almost all of her normals will frametrap, while Attack Lv 4 normals5H, 2H, 6H(2) true blockstring into it. On top of that, it adds substantial pushback, chip damage, and a good on-block to set up her primary RPS into all following options. When blocked on 2K > 2D, this substantially supports her safety.
While this is almost universally beneficial, it carries innate risk to all invincible reversals. Additionally, if the opponent FD blocked, Servant Shoot will likely whiff, leading to a dangerous position. Particularly, 5H is extremely likely to whiff regardless (See: 5H > 236K Frametrap).
... > 236[P] > Backwards Dash
The simplest and least committal. Heavily reliant on distance to work, but escapes most reversal attacks, even long-range moves like Ramlethal's f.S, however it loses badly to fast-moving attacks such as May's [4]6S, and dashing towards you. If the enemy whiffs an attack, you can reset to neutral and utilise the held servant freely. Even if this option fails, it won't be Counter Hit and remains grounded, minimising the damage received.
If the opponent dashes forward and continues to chase, you enter a new RPS situation, further adding complexity. It is not a doomed position and can score a strong counter hit if you guess correctly, making it a low-risk outcome.
... > 236[P] > IABD > j.ws.D
Defeats low attacks at close-range. Gets less distance than backwards dash, loses directly to dashing opponents, and is much riskier due to being in an airborne, counter hit state. However, it can deal with fast low-hitting punishes that are otherwise difficult to avoid, especially from close-range, while avoiding some tall anti-airs. Enemies running up will probably be blocked, unless they punish the landing recovery correctly. Generally this is low reward unless the enemy whiffs a slow attack.
... > 236[P] > 9 > j.ws.D > j.S
Callout punish option. This move will go high up and counterattack from above. Defensively avoids a lot of mid-height punishes, and can get significant distance from enemies if they pre-emptively dash forward, but it is slow and is extremely likely to be counter hit by tall anti-airs, often scoring them the optimal combo conversion. The slowness of the {{{2}}} also makes it likely to lose to any reversal IAD attack.
If this scores a hit, it can effectively combo with the servant and get fairly good reward. If the opponent happens to block it, this can easily lead into pressure strings, depending on their position.
... > 236[P] > 7 > j.ws.D > (j.S) > (IAD > ...)
Retreating jump, branching options. A higher, slower retreat which can be unpredictable. It builds a huge amount of space, escaping the large majority of reversal attacks. By striking a minion it can also disrupt ground movement or call out air-to-air attacks. However, it is very slow and extremely exposed, often giving the oppoent time to react. This can potentially lead into a pressure string.
Using j.S will send the servant at a downward angle. This can punish reversals when at close-range, and prevent them walking forward from further range. If you do not use j.S, you can tech out of Air Throw callouts and can likely block any slower punishes, but will not interrupt air-to-airs and will allow reversal strikes to threaten you more easily.
If you IAD off the servant, you will easily evade any grounded punish (e.g. most dashing 2H attacks), and can convert better off the opponent failing their punish. However, this can easily lose to follow-ups even after a failed reversal attack. Being varied makes it difficult to know which options they can punish with
... > 236[P] > ws.S > ws.D
Reversal callout. A hard callout against high-hitting reversal attacks, especially meterless invincible reversals. One of the only ways to be truly safe from invincible reversals at close range, and scores extremely high value against them. However, it does not move and will be in counter hit state, making it particularly risky otherwise. Unfortunately, it will not work on Overdrives.
This route uses Hitbox Nullifying to maximise the punish potential. If this is not used, you instead put the enemy into Guard Crush, and can proceed from there.
... > 214P (When no servant is near)
Poor man's safety net. Her worst route. Off most moves this leaves her punishable in full counter hit state, and at best only gets to block a slower punish, it offers almost no chance for a counter punish or escape, unless the opponent does a slow recovering air-to-air. It is better than natural recovery, but the risks you experience immediately after makes it an unreliable strategy.
The only realistic use case is at close-range, when you have no servants nearby and no Summon Servant Gauge to use for a 236[P] cancel. The 214P variant is functionally cheaper if it can recover servants in the process, making it usually a better choice, but when no servants are available, all four commands214P, 214K, 214S, and 214H are identical.

Servant Routes

Usually if you can utilise servant commands with a servant in range, you do not need to play a guessing game to escape and in fact are advantaged. However sometimes a servant might be nearby but not actually provide immediate pressure because it is out of range. These routes take advantage of those situations.

... > 214S
Safety from large strikes. Sets up a shield. If the servant is nearby enough to cover all reversals, this isn't for escaping a string and can just continue as a pressure string. When the servant is further away, the Defend Command makes a shield that can catch larger punishes, particularly good at punishing other routes. Even if the shield is behind Jack-O'. Unlike most options this one costs Command Servant Gauge, but not Summon Servant Gauge.
This is particularly bad against short-range punishes, projectiles, and Overdrives. It comes with substantial risks due to the full counter hit recovery, lack of movement to escape punishes, and the fact the enemy will be able to see which moves are at risk in the first place. While the shield covers her recovery, the opponent is likely to set up a punish against her, using Throw or a well-delayed large strike.
... > 214K
Counter-poke. A fairly effective defensive measure, even without hitting. If the servant is nearby enough to hit the opponent, it's not actually for escaping a string, and can just continue as a pressure string. When the servant is too far to hit, the attack command holds out a hitbox the enemy can fall into during their punish attack. Unlike most options this one costs Command Servant Gauge, but not Summon Servant Gauge.
This is particularly bad against disjoints and invincible reversals, and comes with substantial risks due to the full counter hit recovery, lack of movement to escape punishes, and the fact the enemy will be able to see which moves are at risk in the first place.

Character-Specific Interactions

Below is a list of character-specific interactions between effective punish options and escape methods. Currently only May is listed, but more will be added over time.

  • Assumes optimal combo conversions
  • Assumes perfect execution (e.g. punishing landing recovery, instead of Jack-O' blocking in the air)
  • Assumes normal blocking. Instant Blocking and Faultless Defense largely change all of these.

Key:

  • Safe - Successfully escape into a neutral position or can successfully block the punish without leading into pressure.
  • Unsafe - Receive no damage, but forced into a pressure string of some kind.
  • +X - Near to the opponent with the given frame advantage.
  • Retreat - Specific to the Backwards Dash option. Jack-O' has escaped direct punish but the opponent has continued to chase her.
  • Punish - Can deal damage to the enemy before they can recover, or otherwise force them into safe pressure options.
  • Hit Light - Received a light punish as a result
  • Hit Medium - Received a moderate punish, of a small combo string, or giving stronger okizeme
  • Hit Heavy - Received an extremely damaging punish
  • Unmarked - Same as previously listed outcome.

Escape Strategy

Primarily, this tactic is critically important for 2D and 236K. For many other moves, there are either gatling blockstrings into safer options (including 236K) or are virtually unpunishable such as 5H. When cancelling off 236K, the situation is generally disfavoured to Jack-O', as she has a lot of ways to be punished badly, and very few ways to score significant gains on a good read, as a result it is important to always consider this position a net loss, and to avoid it where possible. This is especially true for matchups with better punish options. This is especially true on any opponent with an invincible reversal, as this makes 236K immediately unsafe. However, performing this off a blocked 2D is even more dangerous.

For this reason, an opponent's Tension is important to watch. Not only is it killer in the matchup of Ramlethal, Nagoriyuki, Giovanna, and Ky, any invincible reversal becomes difficult to challenge, and the presense of Blue Roman Cancel almost universally makes this punishable without meter of your own. Without a reversal, especially against Chaos and Zato, this situation is substantially safer as the only reason to ever cancel from the 2D is if the 236 would whiff due to FD block, in which case you're likely already safe.

You cannot simultanously hitconfirm 2D into okizeme, and also hitconfirm a true frametrap with 236K. For this reason, you should invariably plan ahead which option you prefer for the situation if you intend to use a raw 2D. Alternatively, by using 2K > 2D, the 2D becomes hitconfirmable, allowing you to simultaneously use optimal okizeme, while maintaining the safer cancel option.

Counter-pokes

Abare

Anti-air

Jack-O's main control on opponents will derive from her grounded tools utilising servants, however she possess an extremely wide assortment of methods to control aerial opponents. The option will largely depend on available resources, servants, and the opponent's position. Unlike most characters, Jack-O' suffers greatly from even blocking air attacks, due to losing any active Servants, making it very important to avoid the situation. To this end it is often valuable to consider the Servant Gauge, as while many of her options provide little combo potential, they can allow her time to build space for neutral, recharge servant gauge, or deploy servants.

5P - Fast, short-range poke. Weak hurtbox, but is able to act faster than any other option, making it versatile at interrupting fast aerial approaches from close-range. Can combo into 6P for a full-screen knockdown, giving very low damage but time to set up servants.

6P - A very safe anti-air. Has full upper-body invulnerability. Among characters' 6P attacks, Jack-O's is especially versatile with an extremely short hurtbox and good speed, leading into knockdowns at full-screen. Low damage reward, but easily sets up more servants.

2S - Powerful anti-air for opponents directly above Jack-O'. Extremely strong hurtbox/hitbox and fast speed, but its extremely narrow range makes it only useful against attacks directly above her. It can provide substantially better combo potential for high damage output, but can be risky against enemies carefully spacing their attacks.

2H - High risk, high reward. It is a disjoint but has overall short range and is very slow, making it very difficult to land against most air-to-ground attacks. Usually better when an opponent jumps at close range. If it lands, however, the damage potential is immense due to its 100% proration and ground bounce.

6H - Jack-O's longest-range attack. Can anti-air from extraordinary distances with complete safety. However, it is very slow and does not cover above Jack-O', making it only useful against distant foes or pre-emptively attacking an opponent's jump. Has virtually no combo potential even on Counter Hit, but will send opponents full-screen to allow time to set up more servants.

Throw Servant (ws.6X) - If Jack-O' is already holding a servant, throwing it provides a very high projectile to disrupt air-approaches. Doing so sets a servant between herself and the opponent, or by comboing with Attack Command (214K) can set an opponent in the corner with a servant for pressure.

Defend Command (214S) - So long as Jack-O' has servants available, Defend Command acts as a low-commitment and very safe anti-air at the cost of Command Servant Gauge. The Defend Command shields are extremely large and able to catch many common air-to-ground attacks. Guard crushing an enemy in the air provides no damage, but gives Jack-O' time to begin pressure safely. Furthermore, the Defend Command has very low recovery time and protects Jack-O' even after her recovery, making it overall low commitment when dealing with highly mobile opponents with unpredictable air-approaches.

Attack Command (214K) - If Jack-O' has a servant at a high elevation, or is currently holding one, the Attack Command acts as an extremely high-reaching disjoint with decent combo-potential. This costs Command Servant Gauge but is easily her most powerful anti-air when the opportunity presents itself. Performing 236[P] > ws.K is functionally very slow, but hits extremely high-up and will defeat almost any normal air-to-ground approach, particularly good against opponents using Superjump.

Air Throw (j.6D/j.4D) - A useful anti-air for all characters, especially against opponents that like to jump into block. Can be somewhat risky as Jack-O' will be vulnerable until she lands and will not have access to her servant commands.

Servant Trajectories

For playing neutral with Jack-o it is important to also know the trajectory of the minions after they have been hit.

236P minion trajectory

  • A
    • 2P,5P,j.P,5K,j.K,j.D
  • B
    • 6P, f.S, c.S,j.H,5H
  • C
    • j.S, 2H*
  • D
    • 2S,5D,6H(1)

2H goes slightly higher than j.S A and B will be the most commonly used for neutral.
Because of this you typically will be using 5P,5K, and 6P to hit the servants.

  • 6P is useful because it can send it a bit further than normal and has fairly fast recovery
  • 5K is jump cancelable which gives you many options and great for setups
  • 5P fastest possible hit and allows you to combo in certain situations

Frame Traps

Unfortunately for Jack-O, exceptionally few of her normals naturally frame trap into other normals, so you're better off utilizing stagger pressure between normals. However, when it comes to cancelling into special moves from normals you will find that 214K or 236K are sufficiently delayed enough to cause natural frame traps. These frame traps are easy to perform, and since both of these special moves can be combo starters given the correct servant positioning, they have the potential for big and easy damage. Be wary of the frame traps based on Tiger Knee specials, as it is possible to accidentally delay them. Also, specifically for j.236K, frame traps involving this move can be beaten by 6P. The same is rare, but possible for 214K/j.214K while the servant is falling. When the servant is floating at their natural height, Attack Command cannot be dodged by 6P (needs testing on all characters).

To explain the significance of the Frame Gaps, certain moves will win or trade based on the size of the gap. Note these only apply if the move in question can hit, so a gap does not always mean it will always fail;

  • 1f - Invulnerability of some sort is required to beat this frame trap.
  • 2f - Throws can defeat this frametrap (throws takes priority over strikes)
  • 3f - Sol's 5K and Chipp's 5P will trade with these frame traps.
  • 4f - Sol's 5K and Chipp's 5P will beat this frametrap, and Giovanna's 5P will trade.
  • 5f - Giovanna's 5P will beat the frametrap, and any character can at least trade with the frametrap.
  • 6f+ - Every character has an option that beats this frame trap. This is the point where a string stops being a frame trap in this game (but can be useful to catch slower options).

Universal Tech

BRC Instant Overhead


Useful Links:

By cancelling a backdash into a forward drift BRC and fast cancel into j.P, Jack-O' can perform a fast overhead attack. On hit this combos into 2K. This is difficult to react to compared compared to jumps and Charged Dust

, and is still safe, however has generally lower reward.

On block it cannot lead into a true blockstring due to the immediate landing recovery and lack of blockstun. While it is advantaged, it doesn't avoid invincible reversals.

Executionally this is quite difficult as the window to input j.P is very tight. When done incorrectly, Jack-O' will land before it becomes active.

This section discusses a wide range of tech and mechanics Jack-O' has access to. The application of each is largely different.

  • When one (non-held) servant is available, using Recover Servant will spend 0.86 ~ 1.10 bars less Command Servant Gauge and 1.36 ~ 1.60 bars less Summon Servant Gauge than using Defend Command (214S) or Attack Command (214K), followed by improved recharge rate.
  • If Jack-O' hit a servant before recovering it, and only recovers one servant, it is impossible for her to break-even on the cost of using the command even when accounting for the improved Servant Gauge recharge rate.
  • Due to the loss of Command Servant Gauge lowering the gauge limit, the Summon Servant Gauge restored will often be lower than the potential amount.

  • While it is +31 at minimum, it is unlikely to parry on the first frame, this means it will typically be more advantageous than +31.
  • Unlike all other Guard Crush attacks, Defend Command counts for the first hit of a combo. This means its proration and RISC reduction will influence all follow-up attacks.

  • When the explosion begins, the servants are immediately removed and cannot be interrupted. They have no collision, are fully invulnerable, and do not count as an active servant for Jack-O's Servant Gauge recharge. They will also disregard any further commands issued, including Recover Servant (214P).

Unblockable Damage


Jack-O' actually has multiple methods to set up an unblockable. In these setups, Jack-O' prepares a servant to hit the opponent at the exact same moment after she would land Forever Elysion Driver, thereby creating both a Grab and a Strike at the same moment, which forces inescapable damage. However, this can be defeated by certain options.

A correctly executed unblockable:

  • Cannot be blocked.
  • Cannot be safely jumped out from.
  • Cannot be safely backdashed.
  • Can be defeated by invincible reversals.
  • Can be Burst out of.

Strike Timing

The key to all unblockables is the strike component must land during the 2 active frames of Forever Elysion Driver, such that if it lands, they instantly combo into Forever Elysion Driver. Below is a basic list of outcomes based on when the strike lands:

  • Frames 0 or earlier: Strike can be blocked safely.
  • Frames 1~2: Strike combos into Forever Elysion Driver.
  • Frames 3~4: Strike is an unblockable (Up to Frame 5 for Potemkin, Nagoriyuki, and Goldlewis). A Purple Roman Cancel is required to combo.
  • Frames 5+: Strike can be safely jump blocked, but will still hit backdashes. A Purple Roman Cancel is required to combo.

The timing is extremely tight, however having a late strike (i.e. early Forever Elysion Driver) is still preferable as it provides some reward. Even very late strikes can be good, if the opponent is scared of the risk of trying to jump from a well-timed unblockable (the timing is visually incredibly ambiguous, and it is always safer than an early strike (i.e. late Forever Elysion Driver).

One major quirk is that servants move during Forever Elysion Driver's cinematic for 10 frames (this does NOT include its startup and active frames), this means you actually need to time it much earlier than you think. Additionally, since the opponent cannot jump or backdash during this time, they will naturally automatically block it if they're holding back and the servant strikes during this time, so an early strike is never effective.

Unblockable Variants

Countdown Setups:

Countdown
Countdown unblockables utilize the delayed damage of a Countdown explosion. This is usually done by performing a setup such that the Countdown has begun and the opponent is in a true blockstring until the explosion is about to occur, preventing their escape completely. The explosion hits in time to hit their prejump, but is active and large enough to also catch backdashes.
In most setups, backdashing will interfere heavily, as Jack-O' will fall into her own Countdown. As a result both the opponent and herself receive an 80 damage hit and reset to neutral. This can still be more optimal than her metered combo options, but it makes it extremely low value for general purpose. If the setup in question (of which none have been found for this page) places the servant far back enough to not affect Jack-O', it forces 80 damage, which can be further comboed if Jack-O' had 100% Tension, otherwise it safely resets back to neutral. This also removes all servant gauge, making it explicitly very bad for her pressure immediately after, solidifying it as a round-ending option rather than a pressure tool.
Some advantages include better backdash coverage for midscreen use, and the forced damage is much higher at 80, making it viable even without 100% Tension to combo further.
Servant Bounce
Servant bounce unblockables utilize a bounced servant to land on the opponent at a precise timing, while continuing to travel to catch backdashes. This setup can be done much faster, usually by positioning a servant to be hit, and cancelling off it.
In contrast, this option can never harm Jack-O' in the process, is a lot faster, and does not cost any Servant Gauge at all, making it almost invariably more optimal. However, the damage on backdash is so pitiful that it is rendered virtually useless unless you have 100% Tension to combo further.

Non-Wallbreak FED


An unusual quirk of its range buffs in Battle Version 1.05 is Forever Elysion Driver can now reach an opponent stuck to the wall from a distance where it will not cause a wallbreak, allowing any wall stick combo to immediately lead into a corner okizeme, at the cost of 50% Tension.

While many setups exist for this, the only requirement is the ability to reach a specific position in time to use Forever Elysion Driver. The positioning is incredibly tight. If too close, Forever Elysion Driver will cause a wallbreak. If too far, Forever Elysion Driver will whiff and the opponent will escape the wall.

A good visual guide is the timer. The black arrow at the base of the timer should line up with the back of Jack-O's head.

Corner Okizeme

One weakness of this okizeme is a lack of time to set up servants while also performing strong okizeme. Therefore, this setup is most valuable with either already placed servants, or by setting up servants before using Forever Elysion Driver. Note that because you can Forever Elysion Driver, you need only 14 frames to get an additional servant.

While the pressure can be very potent, unfortunately the wall damage will likely be extremely high, meaning any hit will almost immediately break the wall. With Jack-O's unfortunate lack of "wall slump" combos, this usually makes her reward very low. This is still superior damage to the original Forever Elysion Driver wallbreak, but it largely reduces the potential value that can be earned, unless the opponent remains in the corner for some time. Alternatively, it allows her to spend an additional 50% Tension on a second Forever Elysion Driver, functionally resetting the combo for an extremely high damage reward.

632146P, 236[P] > 9 > j.hs.D > dl j.S.
Servant summon and safejump. The benefit of this string is that it immediately leads into safe corner pressure and blockstrings with a full-duration servant while auto-timing for a safejump, allowing more potential mixups, while being reversal-safe. Despite the seeming lack of mixups at face-value, it directly provides more overall value than a basic strike-throw.
If you lack Servant Gauge to perform this, you can either pick up a servant instead of summoning (same frame-data), or use 632146P, 5P (whiff) > 9 > > dl j.S. The 5P acts as a frame-kill, however it mustn't hit a servant to work, and offers much worse corner pressure options.

Hitbox Nullifying


Useful Links:

When using Defend Command (214S), if the servant is released or picked up on the same frame (input buffering enabled) as the enemy strikes the defend hitbox, the servant will not perform a guard crush, instead the hitbox will be nullified without ending their animation. This can enable a lot of unique punishes.

Usefully, you cannot drop a servant during the Defend Command animation unless this occurs, so you can Defend Command (214S) and rapidly press D until it parries.

This technique is used primarily as an extension of the 236[P] > 214S string, to provide meterless punishes, especially against invincible reversals. The only drawbacks are that you cannot regain Command Servant Gauge, since you did not apply Guard Crush, and moves with very fast recovery may not be easily punished. If you intend to punish with Forever Elysion Driver (632146P) then there is no benefit to this technique.

This technique is utilized in the following sections:

Unscaled Countdown


When using Countdown (214H) under certain conditions it is possible to combo into the explosion, and have the explosion deal the same amount of damage as it would had no combo happened. One example can be found here.

When used in combos this allows a massively increased damage output, as it will deal equivalent to 80 damage, alongside its ability to reset an opponent from Wall Stick and remain in a combo state.

It is not yet confirmed why this happens, or what conditions will cause it.
