Rayami, First of the Fallen (48) [Commander 2019]

If a nontoken creature would die, exile that card with a blood counter on it instead. As long as an exiled creature card with a blood counter on it has flying, Rayami has flying. The same is true for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, protection, reach, trample, and vigilance.
