Nah, I put in the description my reason why. Typically Gaea's Blessing is good enough to keep the cards flowing. Ive also had Loaming Shaman in there at times.

The cornerstone of this deck is Saproling Burst. Proliferate would waste time...now i used to have Gilder Bairn in there but with Earthcraft that is infinite so I took him out.
