Yes, obviously.
Well, i wouldn't give up on this cloyster, at least not before testing it on wifi. It might also be strong.
I'd consider converting its speed points that had been previously boosted to either of its hp or its defenses, so it would be more bulkier. It has a 1st priority move (you couldn't ask for more), and its base speed stat is low anyway. It wouldn't make much of a difference. And for me, breeding and ev-training isn't a waste of time. I enjoy the process very much.
And infernape must have a fire-type stab move! Even if the dilema is between this one or eq. Plus, flareblitz is a killing move. And i'd use lifeorb instead of choiceband. If you still want it to have eq, you could replace it with u-turn (although i also like this move). I don't know. Try it on ps aswell in all of the variations you could think of and see in which one it works the best
