That Which Waits

Annihilator 2 (Whenever this creature attacks,
defending player sacrifices two permanents.)
Suspend 7—{1}{c}{c}
Whenever a time counter is removed from
That Which Waits while it is exiled, create a 0/1 colorless Eldrazi Spawn creature token with
"Sacrifice this creature: Add {c}."
It waits, never tiring. But it is never alone.
