Its like the second or third post in that thread where you can find the ban list and all OU mons.
I have a question too though. Wouldn't it be fun to watch strong UU players like all the council people play simuls?
As in get a single good player and have many (at least 3-5) random people (no offense) challenge them in a game that is timed all at the same time. Also have the council player narrate the games (they would be streaming/recording). I'm not sure how many players would be needed to make it challenging but if you are allowed to do multiple battles at once on PS (idk if you can) I think you would probably need at least 3-5 players
I don't think anything like this has been suggested before so idk if this will work but I would totally watch the simul games....
