Gunakadeit, the Dark Hunter

Flying, vigilance
Other creatures you control have ward {2}.
Suspend 6—{1}{u} (Rather than cast this card
from your hand, you may pay {1}{u} and exile it
with six time counters on it. At the beginning of
your upkeep, remove a time counter. When the
last is removed, you may cast it without paying
its mana cost. It has haste.)
