I've always loved Kyurem w/ Draco Meteor, but I think you should try out Dragon Pulse if you're running Modest / 252 Sp atk. You can still make nice KOs, but you won't be forced out. Let that 130 base Sp atk do it's work.
If you're taking 2 attacks + 2 support, I would heavily recommend a 252 HP / 252 Sp Atk /4 Def, Modest nature. Earth Power > Earthquake. That will give you some really nice KOs and make it more of a tankish spinner.
Scald > Surf and Protect > Will-O-Wisp OR Hex > Shadow Ball
Both works slightly better than what you currently have in the end of things.
Very nice bird you got der.
While paralyzing things always annoys opponents, Thunder Wave and the paralyzing status in generally isn't supporting your team a whole lot. Because of this, I could suggest a few things. A. You could run both hazards on Ferrothorn ( New BW2 perk ) and run Psyshock
or something of that nature on Claydol. Or, you could just throw in some Gyro Ball action so you can actually damage dragons when you're wallin' them out.
Looks really cool. I personally would throw in Mach Punch > Grass knot, but that's entirely preference.
