Camerupt and Torkoal both learn Eruption, although I wouldn't advise you use it on them since they're so slow and will probably (definately in Torkoal's case) be attacked first, meaning they'll need a miracle to hit the opponent with the full blast. I wouldn't advise it on Groudon either, but for different reasons.
As for Sceptile, it would also be a waste to overload him with physical moves. His Attack is above average, yes, and he also learns a good physical movepool, that's true. But his Special Attack is much higher and it would be such a shame to see it go to waste. You'll probably be using Leaf Blade anyway, though, but a Special Attack set would be more ideal.
As for the stalling set, I don't like it due to his below average Defence, average Special Defence and average-ish HP. It makes him rely on his Speed alone, and for that he might as well do some special sweeping.
