Litchi’s 236a also helps. The ground version has a period of invincibility to air attacks, so it will stuff a lot of things. Very useful if they use a lot of jumpins in their pressure. However, it’s unsafe on block, so be wary of empty jumpins.
Litchi’s 2a can be a nice anti air as well actually, because her hurtbox is so small during it, most characters have to do their jumpins a lot deeper to deal with it, which makes them more vulnerable to other attacks.
With staff, 4d can be useful, because it is invulnerable to lows on frame 1. Depending on who you are defending against, that can be useful for getting out.
