Watcher of Hours (Murders at Karlov Manor Commander)

Creature Ñ Sphinx - Flying, ward {3}
Whenever you remove a time counter from this card while it's exiled, surveil 1.
Suspend 6Ñ{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.)
