Umm why is everyone "throwing" their votes to people? Anyways, this looks like an ability that can be distributed to multiple Poison Pokemon, unlike Extra Punch. But I would say Steel has been getting a beating this generation with its defenses, but either way it wont change much. Heres a suggestion: give it to Arbok, Muk, Beedrill and a few other select Poison types.
*Triumvirata apparantly has to throw a Positive at cofagragus*
