Drifblim

Drifblim is a unique Pokemon with a great signature ability in Unburden that allows it to act as a one-time sweeper when used in tandem with Calm Mind. Its unique typing gives it a useful Ghost STAB to hit the numerous Psychic-types in the tier, mainly special walls like Slowking, Grumpig, and Hypno, for good damage. Drifblim also has useful resistances to act as an offensive check to the likes of Tauros and Sunny Day Vileplume and to invalidate most Lickilicky variants. Furthermore, thanks to its wide movepool and its other ability Aftermath, Drifblim is versatile enough to fulfill tasks such as leading, revenge killing, Baton Passing, and setting weather. However, its typing sports several crippling weaknesses, mainly to Stealth Rock and Pursuit, leaving Drifblim very vulnerable to the omnipresent Skuntank. Moreover, due to its middling Speed and Special Attack, Drifblim relies on boosts to pose a threat and thus faces heavy competition from Haunter as an offensive Ghost-type.
