Honestly I think once people start picking up combos and actually punishing me for doing silly/stupid stuff (confuse into heal x3) I'm going to have a much harder time. Generally I find that the worst places to deal with are directly below her when she's in the air, and anywhere above her when she's on the ground since she has no normals that can effectively cover those places. When Dan was playing her for like 1 match, I found that super jumping and dashing at the top of the screen was the safest approach vs fullscreen laser. Liz has an especially hard time dealing with rushdown characters. Once someone gets in on her she only has her R action and dead angle to get out of it (if she's in awakening she has the Thanatos reversal super throw).
I foresee bad matchups in Yu because his moves are just too good and Mitsuru because her effective rushdown range is further than Liz's. I'm slightly afraid of Teddie right now but that's only because I have no idea what any of his stuff does, and Naoto just because she's apparently gdlk.
