Mothim

Mothim is another forgotten Bug / Flying-type Pokemon, and for a good reason: he has a crippling 4x weakness to Stealth Rock, making him almost unviable on a competitive team. This, coupled with his paper-thin defenses and several common weaknesses, means that Mothim won't stay alive for very long. He is also slow and easy to revenge kill. It can also be said that Mothim is outclassed by Venomoth, who is faster, takes less damage from Stealth Rock, has access to Sleep Powder, and has a better ability in Tinted Lens. It isn't all bad news for Mothim, however, as he has above-average attacking stats and a good movepool, with moves such as Bug Buzz, Air Slash, and U-turn; additionally, while Mothim is slow, his Speed is decent enough to run an effective Choice Scarf set.
