What's even funnier is I boosted up Klefki with a bunch of items in fear of the two moves I didn't know... aaaand they were just stat-boosters that became completely worthless once he ran out of PP for Eternabeam and Sludge Bomb.
if you have a slot in your party you could add someone with spite or pluck/bug bite, fuse Klefki with them so you can burn the pp even more aggressivly (anti berry move to counter citrus and leppa) and then undo to just keep the moves
