I went with a deck designed to take advantage of death. This isn't new to me, but it was a new approach. Originally, blue was in he mix, but it was not a significant enough presence to justify having a third color. I can sacrifice a significant number of my creatures, often for double duty. Showstopper can turn an ordinary turn into a bloodbath, as Hissing Iguanars and Blood Artist could have a field day on top of it, especially with Emerwilde Augur and Goblin Arsonist in the mix. The 17/14/8 curve is almost too cheap, averaging 1.77, but the Eldrazi Spawn tokens are there to sacrifice, not to pay, so maybe it is OK.
