If you insist on making it a CBer:
Aggron @ Choice Band
Ability: Sturdy/Rock Head
Adamant Nature
EVs: 252 HP, rest in Attack and maybe a little bit of Defense
- Stone Edge
- Avalanche/Dragon Claw/Shadow Claw/Aerial Ace/Iron Head/Earthquake/Focus Punch
- Avalanche/Dragon Claw/Shadow Claw/Aerial Ace/Iron Head/Earthquake/Focus Punch
- Avalanche/Dragon Claw/Shadow Claw/Aerial Ace/Iron Head/Earthquake/Focus Punch
I hope you're good with predictions because otherwise you won't be able to pull this off. Stone Edge is for STAB and takes care of Flying types. Avalanche and Dragon Claw are for Dragons, whereas Shadow Claw hits Dusknoir hard. (well, before it has used Will-o-Wisp that is) Aerial Ace can be used to take Hera on the switch and Iron Head is there if you want another STAB move and it hits Rhyperior harder than anything else Aggron has. Earthquake is just a generally good physical attack to have and Focus Punch can deal some really heavy damage.
