Nice deck. I would highly recommend Karametra, God of Harvests because she ramps everything and makes it possible to play more stuff faster, or at least she does that for me in my Sisay Deck.

I do like the ramp Karametra provides, I just worried she might be a little slow and I was already having trouble cutting stuff as is. Unfortunately, when I tried to make this as toolbox-like as possible, a lot of the extra ramp had to get cut. I'm hoping to get a Sword of the Animist in here as that seems like a great, tutorable ramp engine that I can play much earlier than Karametra. As it stands, the deck rarely has an issue getting to 4 mana(unless I keep questionable hands) and once there I just use Sisay to get Cradle and any other lands I might need. But I'll give Karametra a shot when I'm also testing out that Sword from origins to see which offers more.
