I need one, I'm looking for one, help me find one :3
This is OU, so I can't use Ubers, and I don't want Sucker Punch.
I think Dugtrio is the fastest with base 120 Speed and Sucker Punch as priority.
You can always run Extremespeed on Genesect/Arcanine/Dragonite/Entei to bypass their lower speed and other priorities :D
Edit: Weavile is the fastest with Ice Shard and base 125 Speed and the Three Musketeers + Keldeo + Infernape all have base 108 and Quick Attack/Aqua Jet/Mach Punch
