Most doesn't autowin vs. anything that Sphere doesn't and it doesn't stop the creatures it needs to stop most (flipped Delvers, Griselbrand, Emrakul) because they fly. Grass/Sphere is the optimal anti-attack step package in all but the strangest metagames.
Sphere is great when you are winning. It's pretty horrible when they just need to push one equipped guy through for lethal, same with Elephant Grass - which has the awful upkeep cost.
