I don't think you should - it has 3 Ice type moves on it (including Hyper Beam, thanks to Refrigerate) which is definitely overkill. It can learn some pretty good TM as well, so there is no need for it. If you want to stick to Special Attacks, then it can get the TMs for Psychic, Dark Pulse, and Flash Cannon. There are other moves to consider of course, but those are just some suggestions.
