I have tried this sort of thing before, and I know I am once more light on land for the concept. Still, here it is. I started by looking for creatures that benefitted by having certain kinds of lands under my control, then pared that down a little, probably too much (only 18 creatures remain, and some for mana. It feels as if I am trying to do too much for too little reward here, and I am sacrificing a lot at the top to achieve it. The curve is just silly, at 28/4/7/1 for a 1.53 average.
