Here are two great sets for Rhyperior:
Role: Physical Tank
Rhyperior @ Leftovers
Ability: Solid Rock
EVs: 200 HP / 56 Def / 252 SpD
Adamant Nature
- Stealth Rock
- Roar
- Earthquake
- Rock Blast
Explanation
Rhyperior's defensive movepool is often overlooked. Despite of this, a Tank moveset can be successfully used on Rhyperior.
Because of its sheer bulk, Rhyperior can set up SR reliably. Roar forces out set-up sweepers (even with Substitute up) and also can rack up extra-damage.
Earthquake and Rock Blast are dual STABs. Here Rock Blast is used rather than Stone Edge, so that Rock Blast can break Sashed Pokemon.
Role: Physical Wallbreaker
Rhyperior @ Choice Band
Ability: Solid Rock
EVs: 252 HP / 252 Atk / 4 Spe
Adamant Nature
- Rock Wrecker / Stone Edge
- Earthquake
- Megahorn
- Ice Punch
Explanation
Banded Rhyperior hits especially hard with its EdgeQuake combo and can function well as a wallbreaker.
Rock Wrecker gets STAB and deals a lot of damage, but Stone Edge can be used as a safer alternative without the nasty pause turn. With Stone Edge / Rock Wrecker, Earthquake gets decent coverage and STAB.
Megahorn is coverage against Grass-types and Rock-types, such as Chesnaught and Cresselia.
Ice Punch can easily land OHKOs against certain Pokemon, such as Gliscor / Gligar and Salamence.
Team Options
Pokemon that take advantage over the Water-types and Grass-types Rhyperior lures generally appreciates Rhyperior. Some examples include Rotom-Wash and M-Venusaur.
Zapdos, in particular, shares great synergy with Rhyperior (so does Skarmory).
Although Rhyperior doesn't mind entry-hazards, its team options would require Defog / Rapid Spin support.
