Talking about singleplayer, i usually just improvise a random thing and start just trying to get some good movement from there, and at some point i put like little metas, like i can do a Split, splitcaps, decap or some stuff that look a bit impressive to me.
At mp, i just try to survive most of the time, but sometimes i feel that thing you're talkin', it's like, trying to guess what's gonna do ur opponent next turn, and doing things to catch up his movements, thinking "i know he's gonna move like this cuz -whatever it's tori joints can make from it's position-" and feeling like you're making those movements cuz those worked. It's a bit like listening "eye of the Tiger" and wanting to fight even if u never had fight before
