What I'm trying to do is the following combo into setup:
ji2~df3+mb, f3, d2~b4, d1~df2
then
ia db3+4, *overhead demon hits behind opponent*, df3
Basically I want the overhead demon to cover my incoming air teleport. Of course, the damn thing needs Google Maps to find its way through the teleport and always comes out about a light year away from where I'm teleporting to. I did a little testing, and I think it has something to do with the opponent's hit state. I can do the above setup just fine as long as the opponent is standing up. But if I do it while they are knocked down or recovering from knockdown then it gets all wonky. Go ahead and try it. You can do the above combo and setup, and as long as you wait until the dummy has been standing up for a full second or two, it works fine.
