This is a Blue-Black based control deck that splashes in some Green in order to play Assassin’s Trophy to remove problem permanents and Pulse of Murasa to help stabilize as the game goes long. It looks to generate card advantage with creatures like Snapcaster Mage and Torrential Gearhulk as well as powerful spells like Cryptic Command.
