My opinions after testing the animation-swapped Mewtwo-
-Increase dash speed, as mentioned
-Change b-throw and u-throw because of the model distortions, as mentioned
-Make n-air hits link better. Currently, I feel it only gets off a few of its hits, for some 4-5%. Ground-release hit (with noticeable KB) rarely gets to connect
-Swap Disable for something else; it doesn't work properly, as mentioned
-Slight d-tilt KB increase (better resembles Melee version's juggling ability)?
-Slight speed decrease on d-smash (to resemble Melee)
And, of course, cool taunts. =)
