Psychic types are smart, but humans aren’t complete fucking retards either, which is why the “lmao but one side is smarter than the other” is ironically a low IQ perspective.
Sure, Xatu can predict the future so many stealth strategies will fail, but what’s the prediction going to do against an army of Dark, Ghost, Steel, and Bug types?
And being an army of all those Pokemon and additionally humans, Psychic types can not breed as many Psychic types for future infantry as the Dark, Steel, Ghost, Bug, and Humans can.
Simply having a rotating wall of steel types to guard a bunch of Spiritombs and stronger dark types, then have healers like Blissey, Audino, and humans in the back to heal wounded steel types would be too costly for Psychic types to counter.
