There is almost zero capacity to win through conventional combat, but the Vent Sentinels and the Overgrown Battlements should help. Also, the Warmonger’s Chariots should do a nice job if I can pair them up with Carnivorous Plants, though that is an expensive proposition. Æther Membrane is a bit of a gamble; I have to block the right creatures, and I would prefer to be able to employ it in a white deck where I could block everything and have it backed up by some Black Vise action. I’ve been off on my estimates lately, but I still think this will perform relatively poorly. The mana curve is decent at 4/17/10/9 (2.60 average), offering up the majority of the deck by turn 2 (and 60% at the three-spot are Spirit Guides), but I am not sure that taking Sun Tzu to this extreme is wise.
