With the advent of Halimar Excavators, a blue-green ally deck that includes Mimics and Favors for some punch, just got better. Of course, keeping the Hedron Crabs means I retain second-turn grinding possibilities from two sources (Crab followed by a land and Excavator, which are not mutually exclusive). By turn three, this deck could be more than a quarter of the way through an opponent’s deck, through multiple paths. With the right draws, by turn four, the opponent could have no library left at all. I need to consider some bouncing or counter magic. For a mill deck (or most decks, for that matter), this is exceptionally cheap, coming in at 2.03 average cost on a 9/25/3/2/1 curve. The name comes from the E. A. Robinson poem "The Mill," though I think there is no suicide in playing this.
