Swampert

Swampert carves out a niche in OU as a blanket special wall with diverse forms of utility that can tank hits from the likes of Dragapult, Galarian Slowking, and Hydreigon. Flip Turn allows it to function as a slow pivot that can directly pressure Defoggers while clawing back momentum. Swampert's good defensive typing lets it switch into common special attackers such as Tapu Koko, Magnezone, Heatran, and Volcarona and use the opportunity to set Stealth Rock or generate momentum on forced switches. Swampert can offer additional utility by punishing common entry hazard removers like Mandibuzz, Rotom-W, and Zapdos with Toxic. However, Swampert's lack of reliable recovery makes it susceptible to being worn down from repeatedly switching into attacks and entry hazards. Due to its narrow niche, Swampert faces competition from other bulky Water-types such as Slowbro, Slowking, Toxapex, and Gastrodon, which boast more longevity with reliable recovery moves and Regenerator in the former three's case. While Swampert boasts access to Flip Turn compared to other traditional bulky offensive Ground-types like Garchomp, it lacks the utility of Landorus-T, which is able to remove a Defogger's Heavy-Duty Boots with Knock Off.
