Just finished training a Dragonite I got recently, and I was wondering if it has any good partners in doubles or what item I should put on it. It has the same moves as my White 2 one that wasn't IV bred (Fire Punch, EQ, DragonClaw/Outrage, still debating that one, and DDance). Should I go leftovers like I did in White 2 or go with the new Weakness Policy?

It's Multiscale btw so it should be aight.
