Golurk

Golurk has a unique typing with immunities to Normal, Fighting, and Electric, which allows it to block Rapid Spin and Volt Switch while being one of the few physical attackers in the tier unfazed by Fighting-type attacks. It boasts an extremely high Attack stat with a potent STAB combination as well as solid coverage, making it very tricky to wall. Golurk even has decent bulk for an offensive Pokemon, and it has usable abilities in the form of Iron Fist and No Guard; the former boosts the power of Golurk's various punching moves, while the latter ensures none of Golurk's (or its foe's) attacks miss. Unfortunately, Golurk often fails to fire off as many attacks as it would like, given that is very slow for an offensive Pokemon and carries numerous weaknesses to common attacking types such as Water, Grass, Ice, and Dark, the latter entailing a Pursuit weakness. This hinders its effectiveness as a spinblocker.
