Your designated wall may just instantly lose to Mewtwo depending on its loadout; there's nothing that perfectly defends against both X and Y.
It's not the king of Ubers, but it's a very solid wallbreaker. Or sweeper. Or utility attacker. Or Psychic Terrain user. Basically, it's going to punch holes, and you're going to have to eat that loss and work around it.
