Hydreigon has everything it needs to be absurdly successful in OU except for a better base speed and better typing. It has quite possibly the single-best movepool in OU (Jirachi is the only one that immediately comes to mind that has a comparable movepool, and I'd still say Hydreigon has the edge), really only lacking Thunderbolt/Thunder for coverage. Sorry, I realize this is horribly off topic (Aura Sphere/Thunderbolt 4 Hydreigon in Gen VI), but I felt like that needed to be addressed. EDIT: Habib, after looking at your post, I think you didn't realize just how incredible Dragon/Bug would be. Several Steels in OU have a Psychic sub-typing (Jirachi most prominently), and that would be their undoing when they're hit with STAB Bug Buzz.
