I was working on ways to do different things with poison counters, ideally with unusual color combos, but I ended up back at green. With a vengeance. With the exception of the Core Prowlers, every creature costs under 3, and only the Elvish Herders, among all 23 creatures, do not give poison counters. I went for the smaller, cheaper creatures with the hopes of spreading out quickly and getting boosts and trample to give a lot of counters. The only other time I used Heavy Arbalest was in What's It Gonna Be?, which went 1-2 in late 2010, but that was a slower deck with two colors and no way to untap creatures. Here I am taking all 4, plus three copies each of Instill Energy and Nature's Chosen. The deck can produce a poison counter machine gun. The name comes for the Naja sumatrana, or equatorial spitting cobra. The 20/12/4/4 curve creates, for a poison counter deck, a startlingly low 1.80 average cost.
