>>38985189Buff psychic terrain and give more Pokemon access to psychic surge.
Psychic terrain now also changes the accuracy of all psychic type moves to 100%. That's not OP, since only 3 moves in total have less than 100%, but they would profit immensely: Hypnosis and Zen-Headbutt (and psycho boost..)
Furthermore, the "confused" status condition gets a buff in ps.terrain (it's 50% chance again to hit yourself in confusion). Plus, all psychic attacking moves get a 30% chance to confuse the enemy. Again, only in terrain.
Psychic types are now immune to confusion, just like Dark types are immune to prankster moves and grass types to powder moves.
And then, buff the move Teleport and let mostly Psychic types learn it. It now functions like volt switch/u-turn only without dealing damage, BUT it has increased priority and the opponent's move will be executed before your new Pokemon is switched in. Meaning, Teleport grants a free switch in, similar to Healing Wish. It takes up a move slot and is a psychic type signature move, greatly improving these types in battle.
