Why the hell is Sableye on this list?! Sableye is amazing. Volbeat is pretty good too because of prankster tail glow, baton pass, and thunder wave.
Also I vote Mawile.
Mawile is like the only pure steel type in NU. And with intimidate, swords dance, iron defense, baton pass, stealth rock, and other supporting moves she can be a total beast. Volbeat is useable in OU with prankster Tail Glow, Baton Pass, Encore, Thunder Wave, Substitute etc. etc. Illumise is useless though
