I think that you should mention Rampardos' special movepool. Tauros with Fire Blast is a legit threat with Sheer Force, Rampardos has even higher SpA (still obviously crap though) and can use Fire Blast and Ice Beam to effectively bring down Steelix (4x resistance to STAB Rock moves mean that it can cheerfully wall Rampardos) and Tangrowth. Fire Blast nails the former two and Ferroseed, while Ice Beam gets a really strong hit on Sandslash, Torterra, Rhydon, (also Tangrowth obviously). Therefore I think that an all out attacking set with LO and a SpD lowering nature could be a thing. Head Smash isn't recommended here though, since it sucks with LO and the special moves can take down stuff that easily tank Head Smash. I'm thinking something like Rock Slide, Earthquake, Zen Headbutt, Fire Blast/Ice Beam.
