Clefable

Clefable returns this generation with an incredible ability, an almost unsurpassed movepool, and that ever-so-darling grin. Unfortunately for it, the new generation has not been so nice. It no longer has a niche with Magic Guard; Sigilyph and Reuniclus have usurped its throne as the queen of "who cares about residual damage?" Throw a UU-cast Mew into the mix with an impossibly incomparable movepool, and Clefable finds it harder and harder to stand out among the crowd.

Things aren't all bad for the pink pixy, however; it still manages to put together a very useful support set, and it loves the new Wish mechanics of the fifth generation. It is still a very solid user of Magic Guard, despite not having exclusive access anymore. It also has a reasonable amount of bulk for support and just enough offense to make a Life Orb set plausible.

Clefable didn't change very much with the new generation, but things certainly did all around it; despite these changes, Clefable is still a great Pokemon who can succeed on any team if played to its advantages.
