With the release of ORAS and the evolution of the metagame, it makes sense that there will be some power shifts. I want to know what Mega Pokémon have been either promoted to Ubers, promoted to OU, demoted from Ubers or demoted from OU. I know that certain Megas (Lucario, Gengar, Kangaskhan) were banned to Ubers in XY, but have any of them falled from glory? Likewise, I know that Mega Salamence has been promoted to Ubers and that Mega Rayquaza has been kicked out and into AG, but has there been any other cases like that?
