Marowak

When holding its signature item, Thick Club, Marowak gains a titanic Attack stat, which, along with its good coverage, allows it to 2HKO almost every Pokemon in the NU metagame. Unfortunately, Marowak suffers from various flaws that make it a very mediocre Pokemon. Chief among this is the competition from other Ground-types, as Marowak is very hard to justify using over the likes of Rhydon, Golurk, Torterra, and Piloswine, all of which possess better bulk and typings, allowing them to check far more of the metagame. In addition, Marowak is cripplingly slow, leaving it easily revenge killed, which isn't helped by its common weaknesses to Grass-, Water-, and Ice-type moves.
