Watcher of Hours
Flying, ward
Whenever you remove a time counter from Watcher of Hours while it's exiled, surveil 1.
Suspend 6— (Rather than cast this card from your hand, you may pay 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.)
