Death Guard Jurat

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, Death Guard Jurat has
flying. The same is true for first strike,
double strike, deathtouch, haste, hexproof,
lifelink, menace, protection, reach, trample,
and vigilance.
The elites of Darkwall dealt with most problems
before they could fester.
