Weavile

Weavile's unique Dark / Ice typing carves it out a niche in Mix and Mega, and its high Attack stat, combined with its Ice typing and access to Fake Out, makes it a decent holder of Glalitite. Weavile can effectively use its STAB-boosted Pursuit to threaten some of the Pokemon that it beats and deal valuable chip damage to common Pokemon that it forces out. Weavile carries a good Speed stat that it can use to outspeed many of the Pokemon that it wants to revenge kill. Weavile also gets great Refrigerate-boosted priority in both Fake Out and Feint, and it can use Swords Dance to increase its wallbreaking capabilities. Despite these positive traits, Weavile has abysmal bulk and can't switch into any substantial attacks, which is compounded by its weakness to Stealth Rock. Weavile often has lackluster coverage versus Ice-resistant foes as well, and it is heavily reliant on its Ice-type STAB moves to deal damage.
