Hey Zarel! I don't know if you are the correct person to ask, but i thought since you are 1 of smogon's most involved, you would be a good candidate!
Pokemon BDSP will soon introduce fairy types, maybe regional variants, and perhaps remove hidden power from Gen 4. This begs the question of whether it will have its own permanent ladder on showdown, since it is the gen 4 game. I appreciate your thoughts!
