As you cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less. You may cast it without paying its mana cost. Put the exiled cards on the bottom in a random order.), you may put a land card from among the exiled cards onto the battlefield tapped. (Do this after the last card is exiled, but before deciding whether to cast a nonland card.)
