the premise in advance was sub 3 times, hopefully getting an SD in. on the 3rd sub you're at 25% hp (since you have hp/4) and both salac and swarm activated, allowing you to ouspeed almost everytihng and sweep with double stab MH. Rock slide had the best type coverage so it was chosen as the other attacing move. iirc mop originally ran jolly but i usually ran adamant for things like cune.
in D/P it would be pretty much

It isn't as viable in DP since
choice scarf
tons of sandstorm which hella shortens his lifespan
SR/toxic spikes/spikes which hella shorten his lifespan.
this was one of my fave sets in adv. one of the highlights was almost sweeping mop himself with it except MH missed the 1st turn =((
