For Batgirl :
The gameplan is to keep the pressure on her and run mixups. You can't beat her in a zoning war, do not try. Every mistake leads to huge damage and optimal position for her. Her wakeups are all full combo punishable so abuse her on wakeup but watch for uppercut.
Full combo punish teleports everytime. The combo I use is as follows:
F222 , MB singularity, j2, f2233, This leaves her close so you can abuse her wakeups.
If she gets close with advantage get the fuck out of there. Mb b/f3 , backdash , whatever you can haha.
If you find yourself full screen with life advantage hold down(block) she can't do shit, even chip you.
It's winnable.
