Drifblim

Baton Pass is the main reason to use Drifblim over its Ghost-type brethren; it has a massive HP stat, immunity to common Ground-, Fighting-, and Normal-type moves, and two useful abilities in Aftermath and Unburden. Drifblim also has passable defenses and a variety of good supporting moves such as Hypnosis, Thunder Wave, and Haze. The downsides to using Drifblim are its Pursuit weakness, lack of reliable recovery outside of Rest (unlike other Flying-types, Drifblim does not learn Roost), and crippling Stealth Rock weakness. Overall, Drifblim is outclassed by Mismagius and Rotom, but if you can utilize Drifblim for its good points, it becomes an excellent addition to your team.
