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.
T-tar lead is to counter sash leads, but you should probably swap it to something more consistent. Azelf lead + beat-up weavile arguably works a lot better
For the record I do not think that this team is good. Every time I look at it I am more and more disgusted with myself. That said, it's gotten me more wins than any other that I've used and seems to consistently pull through for me. Can't wait to get aggressively roasted! :psysly...
