Swords Dancer. Fire Punch is for Bronzong/Skarm/Bugs/Grasses. Stone Edge vs Rock Slide is power vs accuracy.

Earthquake
Stone Edge/Rock Slide
Fire Punch
Double Edge/Ice Punch/Thunderpunch

This is treated as a pseudo Choice Bander, except it can switch moves. The first 3 are pretty needed but the 4th slot is up for grabs. Ice Punch ohkos Garchomp, Thunderpunch is for Gyarados as Stone Edge won't ohko bulk versions after Intimidate. Double Edge is a decently safe move to use with Rock Head.

This is my own set. NOTHING survives one of these attacks from a +6 Marowak. I use it with Ninjask + Umbreon + Smeargle. I lead with Umbreon, Mean Look/Yawn/Protect/Pass to Jask, passes speed and hopefuly a Substitute to Marowak, who then Belly Drums and sweeps. If the opponent wakes up early, pass to SashSmeargle, who Spores and passes to Marowak.

I may have missed some viable sets, please let me know.
