When Shivan Sand-Mage enters the battlefield, choose one — Remove two time counters from target permanent or suspended card; or put two time counters on target permanent with a time counter on it or suspended card.
Suspend 4— (Rather than cast this card from your hand, you may pay and exile it with four 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. It has haste.)
