Due to the patch, you can now trait up MID COMBO in the corner and still have somewhat acceptable damage.

**Havent labbed this one as much, so it's way less useful as of now.
EDIT: Turns out you can do these same combos mid-screen as well. STARTERxSTMB, F23, B3 (walk forward), D2x4, d12xLasso. Same damage as noted before.
This is seems very unoptimized, and could probably be improved to end with 113, but I'm not sure.
EDIT: You absolutely can end in 113 in the corner, which makes you very plus. Like really plus. You lose some damage but oh well. Not sure how useful that is, but it felt pretty good to not have to trait up and waste some of those plus frames. Back to the lab!
Very reminiscent of cheetah's trait combos, which is funny given their relationship!
Sorry if this info was already known, but I didn't see it here yet. Back to the lab!
