Beautifly

While Quiver Dance gives Beautifly a chance to act as a sweeper, its awful typing, which gives it a 4x weakness to Stealth Rock, horrible bulk, and subpar Speed make it difficult to use. Even with Quiver Dance, Beautifly has difficulty standing out from other Pokemon of the same type such as Butterfree, which has access to Sleep Powder and Tinted Lens, and Masquerain, which has Intimidate and Baton Pass. Beautifly has access to a situational ability in Swarm, but even while taking Swarm into consideration, Beautifly is still overshadowed by other Quiver Dance users.
