Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
Personally i love the SubPunch set mainly because no one sees it coming. i mean if you bring out one UU poke then they automatically assume your a "n00b." Then you turn around and 4-0 the guy. Gotta love pokemon :D
