Not every Pokémon can be good.

Water/Fairy is a great choice for typing, but it should be defensive instead of offensive. It's going to be running Draining Kiss and Scald, after all.

Fairy
Ability: Huge Fairy: Doubles Attack/Special Attack and gives it immunity to all non-SE moves

20+ to all stats
