Weavile

Weavile often faces competition from the more popular Mamoswine as an Ice-type, lacking the flexibility and utility that Mamoswine provides. Weavile sets itself apart with a fantastic Dark / Ice typing backed up by one of the highest Speed stats in the game, making it a powerful lead and late-game cleaner capable of tackling some of the format's most popular threats. Access to great priority moves in Fake Out and Ice Shard allows it to effectively take down opposing leads and function as a reliable revenge killer that outpaces opposing priority users such as Thundurus due to its high base 125 Speed. A dangerous STAB combination and access to Knock Off and Icicle Crash also allow Weavile to clean up later in the game when its anti-lead capabilities are not necessary.

However, Weavile is incredibly frail, so if it's not KOing the foe, it will almost surely be KOed in return. As a result, priority users that can shrug off a hit from Weavile such as Azumarill and Conkeldurr are very problematic. Weavile also suffers from a poor defensive typing with common weaknesses to Fire, Rock, and Fighting, so it has a difficult time finding opportunities to come in if it doesn't lead. Weavile also lacks access to many coverage moves beyond Low Kick and Poison Jab, so it finds itself struggling against anything that isn't weak to one of its moves.
