At Worlds, Zac Hill played a list with 3 Survival of the Fittest, a Wonder and a Squee, just to gain the advantage in the Thresh mirror since it was one of the most prominent decks.

What do you all think about playing it in this deck?
It would make all of your creatures Tarmogoyfs while giving them all flying and would give you a definite edge in the mirror as well as some flexibility in the SB to give you an edge in the MUs where you need more help fetching silver bullets like Meddling Mages, Gaddock, Harmonic, Dormant and whatnot.
