I actually use Tauros in my OU team on showderp. Lots of viable sets, especially with Intimidate and LO + Sheer Force. He's also viable in Doubles/VGC. Not the best, but still extremely viable.
He's also good on mono-normal teams because LO + Sheer Force and Zen Headbutt takes care of most Fighting types in one or two hits, even without STAB.
I'm just going to roll with 6x Tauros in the rereleases.
