Monoblack list with a strong lategame. Bontu's Monument and Bontu really helps this deck pop off and cash minions in for damage as you cast and sacrifice later on. A nice option is open to splash red for Unlicensed Disintegration, but once rotation happens we lose 8 duals so I kept it monoblack for now.
