Speaking of the Kyurem formes, how will the new moves impact the Uber tier? If Zekrom gets Superpower the band set will be a gigantic pain in the ass. Most Stall teams rely on Ferrothorn, Skarmory, or Steelceus to check powerful physical attackers, however the new Superpower tutor would end the reign of the Steel types and the Roost tutor will bring in different, less seen walls such as the new Regen Ho-oh (I believe an event was announced or something? I don't have the link anymore), Roost Multiscale Lugia, and of course, Gliscor usage will probably EXPLODE in Ubers
Superpower will be great on Zekrom for removing Ferrothorn, as well as not having to use Outrage against Dialga. Bolt Strike / Outrage / Superpower / Dragon Claw seems like a pretty solid set.
Roost Multiscale Lugia will laugh even at Zekrom, though.
