1~upslash for jump punches
2~upslash for longer reach but it is 2-3 frames slower
f4~upslash for more protection
f43 (can even whiff pretty safely to anticipate jump)
uppercut
For air, (AA punch~)kunai is the starter. It's difficult to get an extended combo out of a kunai unless they are really close.
You can d1~upslash for crossups but her d1 is not quite 6 frames and has a bad hitbox so it's risky.
On the topic of nerfs, I'd expect the other thing to get fixed too, just that he didn't mention it. Unless there was no way they could fix it.
