Swanna

In a tier littered with entry hazard users, Swanna cements itself as the best offensive Defogger. A strong Water / Flying STAB combination allows it to hit the majority of the tier for good damage, and a nice Speed tier allows Swanna to outspeed Pokemon such as Mr. Mime and Leafeon. While Swanna has only an average Special Attack stat, its powerful STAB Hurricane and Life Orb can help to remedy this. Unfortunately, Swanna has poor bulk, meaning it can find itself getting KOed early in a match. It's also weak to Stealth Rock, which it's meant to remove, meaning it can get worn down easily if it needs to Defog a lot during the match.
