Expressive Iteration

If you don't play the exiled card, it remains exiled. It won't be available to be played on future turns.

If you choose to play the exiled card this turn, you must still pay all costs and follow all timing restrictions required by that card. If it's a land, you can't play it unless you have a land play available.

If there are fewer than three cards in your library, follow the instructions in the order given for any cards that are there. For example, if there are two cards in your library, you'll put one of them into your hand and one of them on the bottom of your library. You won't have the option to exile either of them.
