>>44708573Look at what other Steel/Rock types needed to be successful. Aggron wasn't going anywhere with a nuke like Head Smash, and needed to drop Rock Head and the Rock typing for pure Steel and Filter. Stakataka has Trick Room, Gyro Ball plus Beast Boost to make up for being slow and requiring immediacy in boosting.
Bastiodon needs more than Body Press for just the bare minimum of being good. I don't think even Solid Rock on top of Body Press is quite there either.
