Diglett has an excellent max Speed of 20, allowing it to almost always go first. It also gets Arena Trap, which allows it to prevent switches (especially to a Flying type or a Pokemon with Levitate, so it can more easily spam E-quake). A Life Orb increases its damage output. Earthquake is highly spammable STAB. Sucker Punch is for priority. Rock Slide hits Flying types. Shadow Claw is additional coverage.
