be the upgraded version of me
Well, Gliscor usually has no problem switching into Heracross aside from Guts-boosted Facade or Swords Dance-boosted Stone-Edge. Gliscor could wall choiced Heracross consistently, and I would say that it is a hard counter to this bug. However, you are apparently talking about the wall-breaking Status Orb + Swords Dance set, which I agree easily has greater problems facing many of the fast mons in Gen V.
Which leads me to the Salac Berry - Substitute MoPCross set, a set successful during Gen III. Granted even with a salac berry boost, with the spread I posted it is only hitting 397, which still does not outrun many scarfers or weather abusers out there, but it should be beating all non-scarfers to the punch. The big reason I thought MoPCross would be useful even in this newest gen is because it helps deal with its cruddy speed. The ability Moxie makes it even more usable, since the offensive edge that it may lack from not having Life Orb / Guts+FlameOrb / third coverage move is somewhat compensated by gaining boosts after each kill. I really think Moxie makes this MoPCross set dangerous. But alas, unlike the alternative wall-breaking SDance set, it has little answer to Gliscor.
