Hey! I don't know if this is the correct place, but i thought since you were one of the OU council members, this would be a good place.
Pokémon BDSP comes out will introduce fairy types, maybe introduce regional variants and remove Hidden power, all for Gene 4. This begs the question of whether BDSP will have its own separate permanent ladder format on Showdown, since it is The Gen 4 game. I appreciate your thoughts!
