Ryhperior is not a special attacker. It's physical.
There are 2 Rhyperior sets I go for. Either: Weakness Policy and maybe packing Rock Polish or in a Trick Room Assault Vest
Also,a Rock Wrecker...? Not the grandest idea. Consider that a desperation attack like Blast Burn, Hydro Cannon, Frenzy Plant, Hyper Beam and Giga Impact. You don't really won't to waste a turn to charge.
Don't play to win, play for fun. Love playing games with people, that's why I love Wi-Fi. 3DS: 1203-9417-6170, PSN: Trixster196, Y IGN: Tommy
