Weavile

Weavile is one the fastest Pokemon in Battle Spot Doubles and one of the fastest Fake Out users. It has great STAB types; the combination of Dark and Ice hits many Pokemon super effectively, and not many Pokemon resist both. Weavile also has STAB Knock Off, which is great for crippling Pokemon that really need their item. Weavile can use its great coverage to deal with Pokemon that its teammates struggle with, notably being able to OHKO the most prevalent Intimidate Pokemon, Landorus-T, even at -1 with its STAB Ice-type moves. Weavile has good coverage to deal with some Steel-types, which would give it trouble otherwise. Weavile is good at preventing Trick Room from being set up, thanks to Fake Out and Knock Off hitting most setters super effectively. However, Weavile is an extremely frail Pokemon that relies on its Focus Sash, and its dreadful defensive typing doesn't help its poor bulk at all and gives it many weaknesses to common attacking types.
