Rayami, First of the Fallen

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, First of the Fallen
has flying. The same is true for first strike, double strike, deathtouch, haste, hexproof, indestructible, lifelink, menace, protection, reach, trample, and vigilance.
