I will say though that like 80% of Ninetale's usage is gonna be Screens support using Light Clay, as providing half damage for strong sweepers is generally better than supporting some rather medicore (and still not terribly fast) Slush Rushers. I wouldn't be surprised if Ninetales-A sees a lot of usage in OU just because of Aurora Veil, though with how much normal screens get used (despite the variety of viable setters,) it very well might not.
Getting them in one turn makes a pretty big difference though imo.
