Clefable is a poke I find incredibly easy to just slap on my team. Especially the support set. In fact, I think she is my most used RU Pokemon. With protect, s gully special defensive set has a good shoot at avoiding the 2KO from the like of Life Orb Moltres` Hurricane. which makes her one of the better firebird checks in the tier (a crit kan pretty easily be an OHKO though, so don`t expect her to do the job alone). But the main thing about her that makes me feel all fuzzy inside, is that she is pretty much the best Wisher in the tier, which really work well with the likes of Moltres and Uxie. Being able to run 1000 other sets is also never a minus.
