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 had never played against a Mamoswine before, and I thought they ran HP/DEF not Spe/Atk. Trust me, it was a wake up call when I saw you take down the Latios from 90% to zero so easy.
my roommate just told me he borrowed my scrafty, and gave me his, which isn't max speed. Sorry for the confusion buddy. Shouldn't have blamed you so quickly.
