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.
Just an FYI, Mega Ampharos happens to be one of the hardest Torn-T counters in existence and can bop Excadrill with Focus Blast. Raikou is bigger Exca bait as far as I'm concerned. Still, I don't care much for the nomination, but I'll just say that.
