Using Elizabeth is quite a challenge. Elizabeth is mostly used to zone your opponent and can also be used to predict what they're going to do, when they will do it, and how they will do it as well. Because of this, she requires the most skill. Every one of her moves coincides with each-other in some way, shape or form. For example, you can 5A into 5C into 2C quite easily. You can also add in Maziodyne (SB) if you have the meter and can time it right. Since Elizabeth has such simple yet effective combos, she can quite easily overtake a round or even a match if your opponent is caught off-guard.
Tips and Tricks
Elizabeth has the lowest health in the game. Because of this, most of her moves are biased towards forcing your opponent out of your "space." When your opponent gets in your space, you have to either push them back out or punish them for coming in. An easy way to do this is to simply know when to go in and punish, or when to throw or maybe use a Skill and back away. If your opponent is planning to use a Super, block or evade as necessary, then depending on where they are in relation to the corners of the area, go in and punish or stay away and use Skills or zone out by Throwing. It's recommended to punish if they're close to a corner. If you can punish by throwing, by all means, go for it. However, if they are not near a corner, you can force them into a corner by Throwing them or using Skills.
