Feel free to move/lock this thread, but I found the solution for those interested. Normally the move is easy to do, however in the command training it's hard when they have you do PP (or was it 4PP?) then 2KKKetc. because he wants to to the duck after the PP2. In other to circumvent that, hit K very quickly BEFORE 2, then when you continue the combo chain it will do it like it's supposed to.
Hopefully that helps other trying to do his command training.
That said, just beat it. I like Zack's feel a lot better in this one. He feels more unique/practical, I guess.
