Here are some tips against Aba.
When she’s in normal mode :
1) IMO you shouldn’t let her transform into moroha mode easily. Once Aba is transformed, she had the tool to desactivate your stuffs and make your life difficult. If you stay close to her and not letting her transform for free, you make her life very difficult ! The basic idea is to stay relatively close to her. In the range of a 2H is perfect, so if she didn’t find the opening and transform whatever, you can land 2H>2D>BL for a knockdown into zeinest setup for, hopefully, a second and maybe a third knockdown, who can lead to a VERY easy victory. I think if you score a KD while she is transforming, your chances of winning the game increase by 25%, because, a second KD means she must untransform, or risk an instant kill. If she have a burst, you can try 2H>2D>warrant (didn’t try it yet).
2) One tool she had to make space to transform is her 1, 2 or 3 hit Overdrive. The third hit is unblocable, so the normal thing to do is super-jump IAD backward before the 3rd one. Now, Testament has a special technique against this (Let’s call it “Miz_Erable’s special NC strat” if you don’t mind) who consist to make NC Overdrive right when the 3rd hit will hit you. Your invincibility frames will protect you and she will be Knockdowned and poisonned. Now I don’t really know what it implies if she only make one or two hits, still have to try… ^^’
3) If she’s in normal mode and have no more bloodpack, it’s a free win ! Run away from her at all means and put all the stuffs you have all around the screen.
When she’s in Moroha mode.
Ok from now you must keep your eye on this Moroha gauge and learn when a KD will put her in this animation and permitting you to IK her. If she’s on 2P side, it a litter latter than after the bar of the “T” of the word “burst” (I don’t know for 1P side).
Keep your gauge for DAA. It’s a sure KD if she didn’t predit you.
If you score a BL while she has a little less than 1/3 of her moroha gauge, it’s a FREE INSTANT KILL !!! Don’t go for long combos allowing her to gain a burst. A very simple combo into 2D>BL>dash>IK mode>IK
Learn to make IK immediately after going into this mode.
I forgot to try if she can be IKed after a DAA, I’ll edit this once it will be done.
If she does 623H double-hit special move, warrant is garanteed between the 2 hits (if she doesn’t roman cancel) even if she does the FB one, but in this last case, the timing is stricter.
If she make the 41236H move during a pressing, the best option I found is to backdash. It’s an overhead who stagger you if you block it high (in this case, it does 0 damage but she can surely follow it up). It possible to interrupt her or warrant, but if you’re too slow, you will be launched ai air-comboed. Backdash is safer.
She is very good into the air. I foud 6K, 6H and warrant rather efficient to deal with it, but the best IMO is air-throw. It's a sure KD into more pressure.
That’s all for now, more to come.
