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.
Hi, would you mind taking the slash off of your Sableye set? I'm thinking that Foul Play is probably the better option of the two, but that's totally up to you.
Hey, I think you can mention something like a Talonflame or Alakazam for a good partner because of their ability to take on M-Venusaur and Ferrothorn. Nice core btw
Just so I don't clutter the AG thread I will answer your question here. The reason earth power is bad is cause then Thundurus proves to be a problem. When sleeping you will only be able to hit it 1/3 of the time allowing it to get a substitute in more easily. HP fire can break the Sub. The only good thing with earth power is hurting M Gengar, but I personally think HP fire will be more useful more often.
