Heatran is a good Rock setter. So is Jirachi. So is Terrakion really, as it gets surprise in its side. I'll think of more later, but those three are the easiest.
Also, I intentionally leave Ferrothorn off that list because its Tank set it so useful, although I may try trading Gyro Ball out for either Rocks or T Wave, since Gyro Ball is pretty much useless.
