I have been trying it, as some mods like Fallen Druid, Crusaders, 1 pulvy and eternity, sanctuary, etc and i made a conclution:
Even an early Spin Carpace, most of the times is not enough defense yo carry on with the FGs attak. At the beginning, i thought that the big difference of this deck (with the druid) against Can Haz Moar Draws was the spin carpace - Oty as CC, but then i realized this deck sacrifices the defense for de CC. Most of the times, it takes pretty long to kill some creatures and you don't have at least 5 SoG to survive long enough. Not even mentioning a mid - game shield. I love the idea anyway.
