REF A+B is an auto evade move that can turn into a nice unblockable. when you use this and your opponent attacks you, you must hit either A, B, or K, depending on what the opponent used to hit you with. Should your timing be right and you guessed correctly, youl fly into the air, divebomb ontop of their head with an UB, and deal some nice damage. A split second after he hits the ground, hit K, and he should pop back up and imitate a small Acrobatic bliss. Getting the timing near right will land you the same HP that a near JF acrobatic bliss gets, while getting the timing perfect will grant you the 60 points of healing with the all move AI. Defnitely risky, but I use it alot since I love it so much n_n
EDIT! Sorry for having it have said MED A+B, my bad. I fixed it though.
