Slayer is a character who gets his main damage from his wide range of combo options. He is also focused on links (comboing one move into the previous move's recovery with no cancel, much like street fighter combos) rather than gatling combos, making him some-what unique in this game. He is especially good at placing certain moves in situations that net him a highly-damaging subsequent combo. This makes him a VERY high risk/reward character. He can also cancel his back-dash/forward-dash into a special move or a jump, adding invincibility or momentum to the each option respectively.
-Good reversal options
-Amazing Movement options
-BDC and FDC
-Can be zoned well
-FD is really effective vs his mixup
-The high-damage combos are on the difficult side
-Steep learning curve (but F that! YOU ARE A MAN!)
I'm giving him a A- rank thus far...

Back Dash/Forward Dash Canceling
Slayer's dashes are teleports. You can cancel these teleports with a jump. You can ALSO cancel a jump with a special move. This adds invincible frames to a BDC'ed special/jump OR momentum to a FDC'ed special/jump. When you are not visible on screen, you cannot be hit. This is true for a BDC or an FDC. FDC'ing through projectiles/long recovery pokes and subsequently punishing the recovery is a very viable way to get damage with Slayer, just as BDC'ing and punishing with a special move (Mappa, Dandy, Bite, DOT.) can net you a large amount of damage. Consider BDC and FB dandy as your reversal options, just like a DP.
You are basically dashing, canceling the dash into a jump, then that jump into a special move to preform FDC or BDC.
BDC one frame jump: This technique will save your ass more than you know. (447+P+K) You will do a Back-Dash Canceled one frame jump. Totally invincible jump. You can also do BDC one frame super jump (4417+P+K) to REALLY get out out of a situation.
-FDC Mappa: (662369K/P) This adds A LOT of range to your mappa hunch. You can use this to punish at long range when your opponent thinks he/she is safe to set up zoning. The CH potential of the combos is amazing.
-FDC Dandy: (662147[P, K, S, H]). This does not have as good of offensive applications as FDC mappa, but it does add forward momentum to your dandy steps. This can be useful as throw/CH bait for your P/K dandy, or added range to cross-over for your S/H dandy
-FDC Bite: (662369H) Dashing Command Throw. Depending on how you delay your jump into the bite (the delay in between the dash and jump-H) you can have a two-three character length command throw that heals you. This is a really important piece of tech that should be in every Slayer user manual. You can use this to throw at a SAFE distance and also punish their whiffed moves for a throw. I personally LOVE this.
-FDC Neutral Jump: (668) This is great for closing in on a recovering opponent. The later you cancel your jump, the more momentum is "installed" on your jump post-dash (66~8). This makes him move forward while having a neutral jump hit-box (skinnier, harder to anti-air, a few frames of invincible from the FDC) and makes his j.H hit in an ideal way for beating anti-airs for a big juicy CH combo. This tech will move you forward safely and put you in the air with more directional options than most of the cast. You can: falling j.H for CH, dj9.H (double jump back j.H) for airthrow bait, airdash back for anti-air bait or airdash forward if you need the space.) This will ALSO install momentum in to your j.2K. When you have momentum on your j.2K, the hit-box becomes larger horizontally and with the new j.2K grounded launch, this opens up a lot of potential for combos. It will also move you quite a ways across the screen.
-FDC DOT: (66321469S) Adds range/momentum to your DOT. Good for when you have your back to the corner as it will carry you further to the other corner. It does not get much use, though.
-FDC UT: (66321469P) Maybe for some crazy blue-moon situational combo somewhere or for some Alladin shenanigans or alligator candy? ..
This is the Slayer Magic. You can cancel your back-dash and add it's invincible frames on to another move. SUPER cool. I'll include all of the useful options in the next section!
-BDC Mappa: (442369P/K) This adds invincibility frames to your Mappa. This is AMAZING for beating mid-range pokes. Use this like a (safe) dragon-punch. If you get a CH, combo into 2K/c.S/BBU/DOT for HUGE damage. You can also use this is a throw bait if they think you are going to dash-throw (66~6/4H)
-BDC Dandy: (21447[button]) You can add more invincibility on your dandy steps. This is mainly good for S, H, and D (Force-Break) dandy as it will cover the start-up frames of S/H so you can assure your escape and make FB dandy un-throwable.
-BDC Bite: (442369H) Sigh.. How the mighty have fallen... No knockdown combo without meter now but, it still does nice damage and heals for a little life. This used to be a great reversal option when the command was different (6321447H) because it was instant out of the cancel. Now, if you don't input it perfectly, it will inherently move you backwards a bit and you will whiff your bite half the time.
-BDC DOT: (63214476S) Makes the start-up of DOT invincible. Really.. Really good.
-BDC DHD (21421449S) Makes your jump into air-super invincible. Also good. AMAZING throw-bait. The input is difficult, though. You know you've done it when you hear the dash sound and Slayer is moving forwards during the freeze.
j.214K. Magic Carpet Ride. This move is amazing as it is one of Slayer's moves that he can adjust the momentum/trajectory on. It is one of his PRIMARY uses of resetting the tempo of a match due to one simple mechanic. FL uses the momentum of Slayer at the moment he does the move to determine the trajectory/velocity of the "Foot-Loose Journey." The best way I have seen/played is (442766214K). That is the command for BDC sj.IAD FL. You can have your back to the corner and you land almost in the other corner REALLY quickly with this technique.
FL can also be used to end combos in a win that wouldn't other-wise kill your opponent. You can sacrifice your knock-down with j.D in exchange for a few hits of FL and a few more other hits for a nice little bit of damage for the win.
And never forget Throw-Dash-Throw. It will WIN YOU GAMES.
Ok no more talk about dashing. Let's get into some combos!
2K. This guy starts a lot of good things for us.
5K-FB Dandy S-mixup
IAD j.S mixup
Hell, we can get a bite mixup off this thing.
-2K-2P-5K-FB Dandy S-mixup
I could go on forever with these combos. 2H has a HUGE potential for resets and combos for gaining meter or placement..
General Combo Theory
As Slayer, you want to carry your opponent close to the corner so that your big-damage combos will work, but also make sure you are optimizing your damage when-ever possible. The best way to learn how and preform is to never tie yourself to one combo route. This game has cut a few routes out, but there are still plenty of them!
CH launch-6H IAD j.K route (works on most everyone! combos vary just slightly!)
6H-IAD j.S/D (On standing. Can combo into j.2K for launch)
Comboing into FB dandy things
If you can combo off a normal hit 5K into FB dandy PB, CW or UP, you should be able to combo off of any higher-level normal. This opens up a few options that we did not have in the last game. Normals into (somewhat) reliable forward pressure are now possible for us, giving us a whole new world of mixup/combo/fear potential. 5K-FB dandy K is note-able as well as 5K-FB dandy P for ending games with low meter off almost any normal hit... This is a huge advantage for us and we should really take advantage of this new option.
