Mind reading is rare and difficult, mind rewriting/control is fictional, teleporting is a specialized skill which is prohibitively expensive over any real distance, and restraining a similarly powerful pokemon is like trying to holding your max bench press. Standard psychic combat abilities become more precision blasts of telekinetic force and disorienting/painful mental strikes.
Of course, none of those limitations mitigate the most OP psychic ability of all:
using telekinesis to steal a trainer's pokeballs and pressing the return buttons.
