Jolteon Bpassing Agility to this thing would be a great idea. Jolteon would Attract Earthquakes which despite a weakness, Rhyperior could easily take. It would also attract the lights of Blissey and other Special Walls that would get their behinds kicked by Rhyperior. If He comes into that, he could even set up Sword Dance, and then it's almost garunteed GG. :)
Or you could go on the defensive side and use Vaporeon along side to absorb bulky waters and then wish back to Rhyperior if your opponent switches into an electric bearing poke. Only problem would be you would have to be one step ahead of your opponent prediction wise.
