Bonemerang is to get rid of substitutes, and while it is not a viable as Earthquake, it is in my mind, worth it for breaking substitutes. Knock Off is to knock off Eviolites, because they are not gonna let you get very far. Now, if you go with Rock Head, use double edge. It is a really overpowered move without the recoil. If you use Battle Armor, then go with Iron Head. And Rock Slide and Fire Punch are completely your option on whatever you want.
