This is a pure spite design, made for nuking artifacts. The 2.73 average cost is really more like 2.13, with some of the cards dropping it being mana accelerators. The 3- and 5-spots are therefore less populated by six (at the zero) and two (at the two). The resulting curves look like this: 7/11/13/4/5 (true) and (6)/7/13/7/4/3 (adjusted). I probably want to get a couple Shatterstorms back in, if only because a single Molder Beast could wipe out an opponent who had been using an artifact deck at that point.
