Yeah, he was saying that the Uber legends WOULD be banned. Things like, Articuno, completely random choice, would not.
Moreover, this is a perfectly acceptable way to ask this sort of question- and that is all he's doing. Asking, and supporting the warrant for the question.
Rhu- All legendaries are banned from league, regardless of strength.
My answer: The Reborn League was created to replicate the flavor of an in-game experience yet maintain the difficulty of facing human opponents.
Never in the games do you see a gym leader with a legendary. Therefore, I've preserved that characteristic. If this were, say a battle frontier, I would not. Naturally, being that the leader's cannot have it, I do not allow the challengers to, either, so that they may be on even ground.
This serves a double purpose as it also shifts the metagame of the league astray from the standard metagame. This is a boon because it opens people up to unique viabilities in their choices- rather than defaulting to cookie-cutter meta-teams. It also challenges the leaders to invent new strategies. For intance, our previous Steel Leader, Titania, was not allowed Heatran- She had to find other, more creative ways to counter fire type attacks.Such an act encourages diversity and critical thinking, for the small price of enhancing the presentational experience.
