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—r (rather than cast this card from your hand, you may pay r 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.)
