This is probably a dumb question, but I’ve been trying to pull off the following combo, but I don’t know how to do the exchange cancel whiff. It’s happened by accident so many times and I can’t figure out what I did…
We have a combo thread bro, you needn’t make a brand new thread to ask about combos. On topic, you have to launch and then drop them quickly(i.e don’t go for your usual 
:h: air series) then do the :df: :h: move and mash :s: and you should get it. Never tried it with ammy but thats how i do it with she-hulk.
ammy takes a little more timing than she hulk. Just practice different timings for the exchange after the df.H. Or watch the video for the timing.
After the :df:+:h: you need to wait after the sword hits the floor and hit the exchange to make it whiff. If you do it too early, ama will still be high-enough in mid-air to make that exchange hit.
