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.
Have you heard of Hidden Abilities for Dream World Pokemon? I got a Drilbur from the Pokemon Global Link's Dream World, Ev trained him, and got him to level 100. His dream world ability is Mold Breaker, so I can hit a Levitate Rotom with Earthquake for example.
I have Pokemon Black and White 2, but I beat the Pokemon White 2 first. Still trying to beat Pokemon Black 2. I have the Pokemon White as well. I used to have a Dragonite, but I traded it away. I EV trained my Breloom and Blaziken in Attack and Speed before I actually started leveling them up.
