Here's an example of how it works, with Shadow Mewtwo and Ingo:
Ingo's Post-Raaaaaaaaah! (Throws Frying Pan)
Shadow Mewtwo's Post (The next one)-Grr... (Throws Frying Pan)
And that's how it's done. I'll start. (Throws frying pan) Now if you excuse me, Ingo and Shadow Mewtwo started fighting and I'm gonna break up the fight before Ingo get's psychically thrown down 2 flights of stairs.
