Talon Gates (Planes) [Planechase Anthology Planes]

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 mana value. 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.
