Japan's All-Star Cup uses the 301 Pokémon in the expanded Unova dex (no bans) so there's hope for the people that want to use Genesect for whatever ridiculous reason.
I got into an argument with my brother over whether it would be fair to compete in the October regionals if it's expanded Unova dex only. He says he wouldn't compete because it would be too easy, because of the people who don't know what's legal until a week before regionals. I say that most serious players would have memorized the list by now anyway, just in case. He says that the expanded Unova dex is a spoiler (serious troll logic there) and would not be posted by TPCi prior to October 7 under any circumstances. Which is complete crap.
