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.
I don't know much about BH, but this does look like a solid squad. But one thing I do know is that you don't have to use Audinite on your Audino-Mega because your already mega evolved. Replace it with a support item like Lefties maybe. :]
Lost against Moods cuz I can't build teams, even though he used the same team every time.
