>>41109130For balance reasons, normal type shitmons are usually given a crap ton of different offensive, defensive, supporting and set up moves. Of all those normal type shitmons, Clefable was the best thanks to her decent bulk and one of the best abilities in the game: Magic Guard, something that other normal shitmons with good movepools like Wigglytuff didn't have. It helps too that in gen 3, they gave it SoftBoiled as an almost exclusive move tutor. And recovery just happens to be on of those things that separates a shitmon from a goodmon
Then gen 5 happened and they gave her Unaware which is one of the best abilities in the game too (it can't use softboiled with it but who cares, is good anyways)
Then gen 6 gave it the best type in the game, Fairy Type. Now, gamefreak knows that Fairy type is an extremely good typing both offensively and defensively, which is why most fairy types have very crappy movepools, even the legendaries. You don't see Fairy types with Fire Blast or something. They usually have their Fairy STAB, some Psychic moves, a bunch of supports, and some flavor stuff like energy ball and thunderbolt.
But, we saw before, Clef wasn't always a Fairy type, it was a normal type, which means it came with a bundle of gifts that other fairies could only dream of: Flamethrower, Stealth Rocks, TWave, Knock Off, and two amazing abilities. And then it dominated the gen 6 meta so hard it made look Lando like a wimp
