Exile the top three cards of your library. Until the end of your next turn, you may play those cards.
Create three Treasure tokens. (They're artifacts with "{T}, Sacrifice this artifact: Add one mana of any color.")
You must pay all costs and follow all timing rules for cards played this way. For example, you may play a land exiled this way only during your main phase and only if you haven't played a land yet this turn.
