Which is why I suggested Sash Mamoswine last year because it was like the Metagross/Heatran of Gen 4. You'd easily set Stealth Rock on the field, but also you were able to Endeavor anything Earthquake/Ice Shard could not cover and while there's not many who resist it, you lacked the power to ensure you could get the best out of Mamoswine's coverage. So, Endeavor picked off any loose ends in a battle where you may have trouble dealing with a particular wall of some sort.
I'm liking Jolly + Life Orb, however, Icicle Crash/Spear has me torn in two because while I do enjoy breaking Substitutes, at the same time I realise that the likes of Thundurus-t will outspeed me before I get the chance to attack anyway; hence why I think Ice Shard is still the sets most utilized move. Earthquake is traditionally powerful and thankfully those who resist it are commonly dealt with by Ice-type attacks.
