Cilende, Overseer of Demise

Eminence - If Cilende is in the command zone or on the battlefield, creatures you control gain delay 3. (If this creature would die, instead you may exile it with 3 time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost.)
Flying, vigilance, haste
At the beginning of your upkeep, remove a time counter from an exiled permanent.
