Encore, Substitute, Leech Seed, Sleep Powder.
Hold Leftovers.
Don't invest in HP and go for a low HP IV, invest in the defenses instead - this is important, because since Gen V Leech Seed is calculated off the opponent's HP, so you'll heal for a higher percentage of your own HP if it's lower than your opponents, meaning you can substitute for longer if not indefinitely.
Max out speed as much as possible
Switch it in on some move it doesn't care about, like setup moves, Earthquake, weak moves it resists, etc and use Encore, then Leech Seed, then Substitute until they're dead.
Use Sleep Powder for extra trolling and to help take care of Pokemon that would otherwise screw you over.
Watch out for Smogon Birds. You're pretty much fucked against Smogon Birds.
