The discussion is useless at this point, I'd like to point out that shed shell is considered by everyone a valid counterplay option (even worry seed) on a plethora of pokemon. The fact that heatran joins this group shouldn't be a problem, really. Your argument about quagsire is misguided, I was merely saying that we are using a shitmon with a strong abilty in OU, in the same way we could be using diglett or trapinch. You seem to suggest that it's ludicrous having a diglett trap a staple OU threat such as heatran. I find this argument nonsense for the aforementioned reason.
