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.
Didn't the most recent SPL rounds have teams with Dugtrio at a less than 50 win percentage? Not sure if I read that right before. Personally don't have any issues with Dugtrio.
For the upcoming tournament do line-ups have to be set/submitted or could you conceivably use a different team every match? I know there is mention of discussing teams in the cheating section of the tournament rules but I guess it becomes harder and harder to have a "surprise team" the longer...
