some mixups:
after 2c:
tk 236b for right left mix up
after 236c in corner:
SJ922b for right left mix up (delaying the SJ will change the side)
after midscreen 236b
walk away and iad j.a for right left
you can j.22a/b after a 421b, meaning you can return to neutral or apply pressure using the a or b version.
after a midscreen knockdown:
SJ9, backdash, cross up j.b.
well, there are plenty of tricks to do at wake up. being as unpredictable as possible helps. for example, after a knockdown in the corner you can jump, j.b, ad, j.a, land throw, or j.b dash jb j.236a. or backdash 623[a]/. if you want try something new in the middle of a match, do it.
