I'm going to completely ignore that Scoop Up Cyclone is illegal for Worlds and will cut straight to the point.
In addition to what others have said, I feel that a Klinklang list (either PlasmaKlang or Gear Shift, or even a hybrid mix) would do rather well. PlasmaKlang is incredibly useful, since a lot of attackers in this metagame are EX, with only things like Absol or Kyurem being exceptions, and even then, the main attacker, Cobalion EX, can take care of them rather nicely - Steel Bullet is an OHKO, and Righteous Edge keeps knocking off Special Energy. (I'm aware Raiden Knuckle can get it back, but it costs the PlasmaBox player a turn.)
And of course, Gear Shift just has a ton of toys at its disposal, being able to utilize Landorus, Keldeo, and Darkrai as well.
