Ulmiraj's selling point is Huge Power which jacks its otherwise poor Attack stat to levels on par with Mega Mewtwo X. Unfortunately, it has low bulk and middling Speed. Play Rough gets STAB. Drill Run hits the Steel, Fire and Poison types that resist Play Rough for super effective damage. Its low base Attack stat lets Foul Play dish out plenty of damage. Life Orb gives it even more power, while Focus Sash lets it take at least 1 hit.

Pairs well with: Clulauder, Illumise, Conotox, Matakoda
