Golurk

One word to describe Golurk would be "interesting." Golurk's solid Attack and respectable defensive stats make it a reasonably powerful and bulky Pokemon, with a movepool allowing it to effectively capitalize on these traits that includes Stealth Rock, Rock Polish, and an assortment of solid attacking options. Its unique Ground / Ghost typing grants Golurk useful immunities to Normal-, Fighting-, and Electric-type attacks, as well as a handful of resistances that give it numerous opportunities to switch in and dish out attacks.

Of course, not all is well for Golurk. Its typing, while granting it some very useful resistances and immunities, does make it vulnerable to several common attacking types, including weaknesses to Pursuit, Aqua Jet, and Sucker Punch, making it somewhat easy to scare out with common Pokemon. To add to this, Golurk has trouble overcoming Cryogonal and Kabutops, the best Rapid Spin users in the tier. Several common Pokemon are immune to Golurk's STAB moves, forcing it to play incredibly careful with its attacks, especially when utilizing Choice Band. Nevertheless, Golurk is a very useful Pokemon in the RU metagame, and with proper support it can prove a deadly threat.
