I don't remember all of the moveset, but you can run Eruption in one moveset. Another choice is just a sweeper. He can also SR and WoW. So its your choice.
He's slow, and most likely will be attacked first. I don't think Eruption will work well...
Typhlosion is your Erupter. Choice Specs Eruption is incredible.
He CAN erupt. It doesn't mean he's good at it. LOL. Anyways, he would be good in a trick room team. Then he will easily blast away with eruption. Camerupt isn't exactly the best pokemon to battle with. Its not defensive and is to slow to sweep. So your best bet is to load up as much HP and defense into him and hope to sweep as a miny-tank. BUt if he isn't used in OU or BL teir, he can work. What their is he? UU1?
