[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dragonstrike]

A lot of the Fairies can only be caught in unusual circumstances. Snubbull, Jigglypuff, Cottonee, and Marill are the only common Fairies, and only Whimsicott and Azumarill is respected in battle. The Ralts line has always been respected in battle, but it's pretty rare and used more for its Psychic attributes than its Fairy. Same is true for Azumarill - people probably don't train Play Rough on it all that often.

And Togepi is traditionally a sign of trust from highly respected people such as Johto's Kimono Girls!  Quite possibly one of the rarest Fairies to have as a result, since they're almost impossible to find in the wild (in the games, anyways. Wild Togepi are always in very special areas/exceptions to the rules).

And the only Fairy type attacking move they learn without a TM or tutor is Fairy Wind, so it'd make sense that'd nobody would ever use it for its Fairy STAB once it has more powerful moves at its disposal that equal or exceed a STAB Fairy Wind's Power.
