  Playing the cards exiled with Ardent Dustspeaker follows the normal rules for playing those cards. You must pay their costs, if any, and you must follow all applicable timing rules. For example, if one of the cards is a creature card, you can cast that card by paying its mana cost only during your main phase while the stack is empty.

  Any cards exiled with Ardent Dustspeaker that you don’t play remain exiled. You will not be able to play them on later turns, even if Ardent Dustspeaker’s ability triggers again.
