Black arguably has the best low-cost creatures in Standard right now, between Knight of the Ebon Legion, Gutterbones and Priest of Forgotten Gods. Paired with Ayara and the Cauldron Familiar/Witch's Oven combo, they form an aggressive deck with a powerful late-game. Even Golos has a hard time stabilizing with sweepers when you refuel so easily with Midnight Reaper.
