Sorry if this is all old tech but I found a couple variations of a full undizzy burst bait in the corner:
cr.HP, j.HP, ADC, j.MP, j.HP, jb.LK (can be followed up with j.HK, scalpels, cr.MK if they don't burst right away)
cr.HP, j.HP, j.HK, ADC, j.MP, j.HP, jb.LK (same followup)
cr.HP, j.HP, ADC, j.MP, j.HP, jb.MK (first hit only), j.HK (into scalpels etc if they don't burst)
I've done a bit of testing on various characters (this was all done in the beta but I'd assume it would work in the normal version of the game as well) but haven't managed to try it on all of them yet. The first one works on Beowulf, Eliza, Ms Fortune, Robo Fortune and Valentine but not BB, Squigly or Double, the second works on Beowulf, BB, Robo Fortune, Ms Fortune, Valentine and Eliza but not Squigly, the third works on all heavies and Beowulf but not Eliza, Ms Fortune, Valentine. None of them work on Cerebella, Filia, Squigly, Parasoul, Painwheel or Peacock.
If I haven't listed a character it is because I haven't tried that reset with said character though I intend to test the other characters later. Also, with the jb.LK ones, the timing can vary per character (there is a tiny delay with BB and Eliza but not Robo Fortune).
