5th Gen Would a Jolteon be able to beat a Cloyster?

I have Black 2

I am pretty new to EV training and what not since I haven't played Pokemon since Saphire.

Anyway, my friend has a lv100 Cloyster, I haven't battled him yet, but his Cloyster has like 500 defense, and I don't remember what else. But from my research I have found Cloysters base stats for HP and Special Def is VERY low. I have a Jolteon with about 350 Special Attack and 359 Speed. So I would think I could easily take it out with a thunder bolt maybe even a volt switch. But he knows about my Jolteon and still boasts about his Cloyster as if my Jolteon is no threat, so I am thinking that he knows something I don't. Anybody know if my Jolteon is capable of taking out his Cloyster with ease?

Uh, yeah, it won't be a problem. Battle him and whoop the floor with him.

That said, this is the wrong section, and since I answered your question, there is not point in keeping it open so I'll be closing this thread.
