I've been hearing and reading mixed answers on this question, so I'd like to try and get a solid answer. Are my pokebank move pokemon legal for the upcoming regionals, even though they're not technically out in america?
The only Pokebank moves that are legal are the ones that are Sketched onto Smeargle, such as Dark Void, Shadow Force, etc. Pokebank abilities and Egg moves obtained through Pokebank Pokemon are legal, however.
To be clear, if you bring a previous Pokemon that was NOT CAUGHT in the Kalos region (even if they are in the Kalos Pokedex), they are not eligible to participate. HOWEVER, you may use them for breeding purposes, as long as the move is in the offspring's Egg Move List (Note: The offspring MUST BE in the Kalos Pokedex).
