>>3527564090% of the time you would be clicking Wood Hammer, Horn Leech, Natures Madness, Superpower, Stone Edge, or even Zen Headbutt. I don't think it would have room to even run it(maybe on a Scarf set, but you would use Wood Hammer allot more in practice). Fairy and Grass have bad offensive synergy, so it's lack of physical Fairy STAB barely affects it's viability.
