Rulings:

• 1/24/2013 If any opponent has no land cards in their library, all the cards from that library will be revealed and put into their graveyard.
• 1/24/2013 The cards will be put into graveyards before the spell you cast to cause the ability to trigger resolves. However, none of those cards will be in a graveyard as you cast that spell, so they can’t be chosen as a target of that spell.
