Being good both as an offensive and as a defensive mon, Misy is able to do everything he want. Set-uping, both slowly with Calm Mind or to break with Nasty Plot, a strong scarf with his 19 speed, a cool breaker with Life Orb, taking advantage of his good bulk with Berry Juice, learning Will O Wisp... To all of that, add a pure type Ghost making him checked by most likely Munchlax, which hate to get burned, and you've an almost unstopable and unpredictable monster. While some other things might looks strong, such as Sun or Abra, Miss(he's using WoW.)dreavus need to be banned for his versatility while being able to do the job with any set that he's played, and the impossibility to cover every Misdreavus's sets without being weak to the whole Univers.
