I think Frosmoth deserves an OU page. With access to Quiver Dance, Tailwind, and Ice Scales, it becomes a specially defensive, threatening sweeper which can tank Dynamaxed Dragapult flamethrower and easily 1 shot with Dynamax blizzard. It can set up on entry hazard Pokemon that are NOT physical and Steel/Rock type such as Ferrothorn and can easily 0HKO non-specially-defensive Pokemon with neutral STAB moves and one Quiver Dance. For opposing Pokemon in high speed tiers like Dragapult, you can tailwind to out-speed in one turn instead of Quiver Dancing, which also gives allies priority.
