Wingull

Wingull is capable of reaching the coveted 19 Speed tier, meaning it can outspeed almost all of its unboosted foes and hit them hard with one of its powerful STAB moves. Although Wingull must rely on Hurricane's shaky accuracy in order to beat the Grass-type foes that resist Scald, this is remedied by the fact that Wingull functions very well in rain, which provides Hurricane with perfect accuracy and increases Scald's power by 50%. Unfortunately, these are the only two significantly powerful options Wingull has access to, meaning it can be walled by specially bulky foes such as Chinchou and Porygon. Wingull is also very frail, and although it resists some common priority attacks such as Mach Punch and Aqua Jet, any Pokemon that can withstand a hit will usually OHKO it in return, especially with its Stealth Rock weakness and Life Orb recoil taken into account. Despite Wingull's flaws, it can be difficult to stop in the rain without a Choice Scarf user, as its decent Special Attack stat and Life Orb mean very few Pokemon can safely switch into it, especially as Wingull is capable of punishing switch-ins with Knock Off and U-turn.
