Instant, U (1)
Rare
The next sorcery card you cast this turn can be cast as though it had flash.
Draw a card.
A skilled Izzet chronarch can carry out an epic vendetta between the fall of one hourglass grain and the next.

2/1/2006: You don't choose a sorcery card when Quicken resolves. Rather, this sets up a rule that is true for you until the turn ends or until you cast a sorcery card, even if you cast that sorcery at a time you normally could.
2/1/2006: If you cast multiple Quickens on the same turn, they'll all apply to the very next sorcery spell you cast.
9/25/2006: After Quicken resolves, you can Suspend a Sorcery in your hand any time you can cast an Instant. As soon as you actually cast a Sorcery, you lose this capability.
