Sneasel

Sneasel has the makings of a good sweeper: it is incredibly fast, has acceptable attack power and it has fantastic dual STABs in Dark and Ice. This allows Sneasel to perform a rather specific niche in targeting notable threats, such as Serperior, Jynx, Swellow, Exeggutor, Haunter, and Golurk. Sneasel is a total glass cannon though, as it is extremely frail with 55 / 55 / 75 defenses. Sneasel's biggest drawback however is that its moves have only average power at best, with none of its STAB options reaching 80 base power. This really hurts its offensive potential and forces it to only target Pokemon weak to its STABs. Thankfully, it does a decent job at it, particularly being the best Jynx trapper due to Dark STAB and greater speed, making Sneasel a very specialized Pokemon in the tier.
