Rhyperior

Rhyperior's combination of physical bulk, useful resistances, and offensive presence lets it be an effective Stealth Rock setter on offensive teams. A Rock / Ground typing makes for a fearsome STAB combination that enables it to threaten one of the most common Stealth Rock setters in Registeel and force a decent number of switches, especially if opting to wallbreak with its Choice Band set. Said typing also provides some great resistances in Fire, Flying, and Rock, making Rhyperior a good check to the likes of Salazzle, Noivern, and Choice Scarf Tyrantrum. Solid Rock somewhat makes up for Rhyperior's many weaknesses by letting it take a super effective hit from threats like Nidoqueen and +1 Zygarde-10% to KO back. However, it's easily forced out by common Pokemon like Milotic and Shaymin, which can be vexing for offensive teams to switch into. A lack of recovery outside of Leftovers and pathetic Speed make Rhyperior easy for strong attackers to pick off mid- or late-game.
