This is less of a "YOU WON'T BELIEVE WHAT YOU SEE! TELEPATHIC HIPSTER POKEMON BRUTALLY MURDERS 6 POKEMON IN SECONDS?!" and more like a "Weary trainer unfortunately hard switches into their wincon on Mega-Medicham's fake out for reasoning that we can't yet figure out" kinda thing.
I know your post is like half bants but I've heard that the council dudes are trying to ban cham, which is pretty confusing. Cham is the exact mon it was in ORAS, they all still run fakeout, HJK, and whatever 2 moves their team needs for coverage.
Trust me, had I misplayed as much as that one switch after a full game with all the momentum on my side, I guess I'd slot myself into PU Monotype as well
