Oracle

Plane - Dominaria 

Any time you could cast a sorcery, you may exile a nonland card from your hand with X time counters on it, where X is its converted mana cost. If the exiled card doesn't have suspend, it gains suspend. (At the beginning of its owner's upkeep, they remove a time counter. When the last is removed, the player casts it without paying its mana cost. If it's a creature, it has haste.)
Whenever you roll Chaos, remove two time counters from each suspended card you own.

Officiele rulings

6/1/2012
Exiling a nonland card from your hand this way is a special action. It doesn’t use the stack and doesn’t count as casting a spell or activating an ability. Players can’t respond to this action, although they can respond when you cast the spell after the last time counter is removed.

The first ability may be used any number of times.

Even after the game leaves Talon Gates, each of the suspended cards will continue to have suspend; the owners of those cards will continue to remove a time counter from each during their upkeeps.
