Whimsicott

Whimsicott is a very versatile Pokemon; its good offensive Fairy typing and immaculate Speed tier let it revenge kill Pokemon such as Swords Dance Gallade, and it has a defensive presence with its great typing, Prankster, and ability to annoy opposing Pokemon with status moves. It is difficult to play around due to the unpredictability that comes with the great variety of sets it can run and its Speed. However, Whimsicott lacks the Special Attack and coverage to deal much damage. This makes it rely on utility and status moves to disrupt foes. It also lacks great defensive stats to constantly check threats such as Regirock.
