Thanks for all the help!
I see, if that's the case I'll stick with Gliscor. Thanks for pointing that stuff out.You could but then you'd be running at a higher risk of Heracross annoying the living hell out of you, but I suppose if you don't run into any SD'ers, then the combination of Forretress (Megahorn), Spiritomb (Close Combat) and Lucario (Stone Edge) should take care of it, as that's your only risk. Although if you do switch, Spiritomb almost has to have Will-O-Wisp to stop the Lucario from sweeping.
