Smeargle

Smeargle is a centralizing Pokemon in the VGC metagame due to its utility and ability to shut down both foes with Dark Void. It has an amazing support movepool that allows Pokemon such as Mega Kangaskhan and Xerneas to set up more easily. Dark Void, however, is the best support move Smeargle can learn and the main reason why you should use Smeargle. Moody can be a very useful ability, as if Smeargle gets one Speed boost, it becomes a huge threat that can fire off a fast Dark Void, so even faster foes will have trouble stopping it; however, a Speed drop allows foes to easily outspeed and KO Smeargle. Smeargle also has horrible defenses and a bad Speed tier, which leaves it outsped and KOed by many Pokemon in the metagame. Smeargle's Speed tier also leaves it vulnerable to fast Taunt users.
