>>53479545Ubers is a banlist first and a tier second. We know stuff like Reshiram, Giratina-Altered and a few variants of Arceus are crap in Ubers (actually, this could have changed but you get my idea) but it doesn't mean they should drop to OU.
The fact that things got banned from Ubers was just a testament to how utterly absurd they were.
Interesting, once in the XY meta they tested Giratina-Origin in OU and while it was clearly the best thing in the bracket it wasn't absurdly broken there
