There's a set that has Stealth Rock, Spikes (one of these can be replaced by Taunt or Recover if I remember correctly), Psycho Boost and HP Fire or Thunder. This set isn't meant to be used as an common attacker, like a bulky Rotom-W. This set is meant to beat spinners and hazard setters, like Tentacruel (Psycho Boost), Starmie (Thunder) Forretress and Ferrothorn (HP Fire). The Life Orb is necessary because only then its attacks will be strong enough to OHKO the aforementioned threats, even with max investiment in SpA and a Modest nature.
