When the last is removed, the player may cast it without paying its mana cost. If it's a creature, it has haste.) Whenever chaos ensues, remove two time counters from each suspended card you own.

(For each suspended card you own and each permanent you control with a time counter on it, you may add or remove a time counter.)
