Quagsire

Although Quagsire has mediocre stats, it works well in Ubers thanks to Water Absorb and an immunity to Electric-type moves. Quagsire has one main purpose in Ubers: to be one of the best Kyogre checks in the game for sand teams. It doesn't do much else, but Kyogre is such a force in Ubers that Quagsire can be useful if you can find nothing else to check Kyogre. An immunity to Thunder Wave sets Quagsire apart from Latias as Kyogre may carry it, which could be devastating for Latias. Without its STAB Water moves, Kyogre is forced to use Ice Beam, which cannot threaten Quagsire without Choice Specs. Encore, Toxic, and Yawn give Quagsire an effective support movepool, which can be used to cause switches and inflict status on opponents. This can be extremely helpful when used in conjunction with entry hazards, such as Stealth Rock and Spikes. Quagsire's main downfall is its low offensive power. This makes it an easy Pokemon to set up against, and it's especially vulnerable to Pokemon with Taunt.
