I'm thinking band Sucker Punch is the best set here. A revenge killer to set-up sweepers, it also provides a check to Ferrothorn with it's fire typing, as well as outspeeding the other wall-ish steels. It gets screwed by Terrakion though. Life Orb or Band is what I think.
Specs Heatmor might be ok, or even Expert Belt. Predict Heatran/Terrakion in and KO it with HP Ground. Then Volcarona or something has a clear sweep. You'd probably want a Donphan to cover it, because it can Spin, and make the opponent think you don't want them to switch often with SR, when you really want them to switch.
