Oh yeah. I'be felt the sting of that Lanturn... *shudders*
And yeah, I get what you're talking about :) and while I know that Stone Edge is shaky to rely on, it seems to be the best choice ATM to counter both of them bar, say, Scarfmie. In theory, Scarfmie would work here, as it wipes the floor with both Dragonite and Infernape, as well as a Suicune / Blissey crippler, but I don't see huge synergy with Lanturn there.
But I can keep thinking :)
