Sneasel

Sneasel carves itself a niche in the RU tier by virtue of its unique Dark and Ice STAB moves that make it difficult to switch into, as few Pokemon in the tier resist both; combined, they hit a wide expanse of the tier for super effective damage. This makes many common physical walls such as Mandibuzz, Rhyperior, and Slowbro wary of switching in on Sneasel. Additionally, its high Speed stat puts it above most of the unboosted tier, which, combined with its STAB Ice-type priority, makes it difficult for offensive teams to deal with and a great revenge killer for prominent offensive threats. Sneasel's access to Pursuit allows it to trap Psychic- and Ghost-type Pokemon as well as catch threats that are weak to Ice as they switch out for big damage, which is a unique trait among Dark-types and sets it apart from rivals such as Drapion. However, Sneasel's frailty and poor defensive typing lead it to contribute little defensively and leave it unable to switch in on much, and a weakness to Stealth Rock can lead to it being worn down quickly. Also, a lackluster base Attack stat means Sneasel hits neutral targets for low damage and often misses OHKOs or 2HKOs on some bulkier targets, even those weak to it, which prevents it from dealing huge damage to teams from the get-go and means it requires support to realize its full potential.
