Interestingly, Steel and Dark as a type combo now have unresisted coverage, as opposed to Fighting/Dark.

Pokemon with Dark Pulse/Flash Cannon, or Crunch/Iron Head now have great coverage.

Hydreigon and Lucario both come to mind, as Hydreigon has naturally great coverage, but always lacked perfect neutral coverage.
Lucario, now preffering Bullet Punch to Extremespeed has Dark, Steel AND Fighting all as coverage moves. That's actually pretty damn good.

Any others we can think of?
