Quagsire

Quagsire is one of the best recipients of a Speed or Special Defense boost from Baton Pass in GSC UU. Getting either boost allows it to set up Belly Drum more easily against many foes and become a fearsome offensive threat that can sweep teams on the spot. Quagsire's great typing gives it only a single weakness to Grass and an Electric immunity without the usual weakness to Ice or Water. Quagsire also fits outside of Baton Pass teams, as it can do well as a Belly Drum sweeper with paralysis support. However, Quagsire struggles against Haze users due to its terrible Speed, even being outsped at +2 by Haze Crobat. Quagsire also lacks many resistances, meaning that some of the most common attacks of the tier, such as Nidoqueen's Earthquake, Hypno's Psychic, and Blastoise's Surf, do enough damage to discourage it from setting up. Due to its low Speed and reliance on Belly Drum for power, it is easy to revenge kill if it has not received a Speed boost. Quagsire's defensive utility is also questionable, as it cannot run RestTalk without sacrificing coverage or a boosting move, and it is outclassed as a mixed RestTalk user by Piloswine, which sports a superior STAB combination and higher Attack.
