Same reason Savij and other pros dont use it. I don't either,  and in my small sample size, I'm 9-0 including facing aggro shaman, tempo warrior, cthun druid, tempo mage, midrange hunter, and more, albeit at crappy ranks just messing around. It's a great card if you're going to run soul of the forest and other more token focused cards, but I prefer more of a ramp deck. Power of the wild is good because it synergizes with your violet teachers, and is another fandral target. spending seven mana for a board of 1/1's is quite an investment and can be punished pretty easily, although of course getting it fandral-ed is quite nice. It's totally viable and jackiechan uses it in his deck, and surely many other good players as well. just a choice of which way you want to go with the deck. i prefer cutting those wisps for ragnaros and mire keeper and things of that nature. i prefer more of a value/midrange game to combo-token focus.
