Whenever you cast a spell, each opponent reveals cards from the top of their library until they reveal a land card, then puts those cards into their graveyard.
i really can't understand the power of this card. It does 2 things that doesn't interest each other, i mean the power like the cards in the graveyard and to finish the opponent library.

If any opponent has no land cards in his or her library, all the cards from that library will be revealed and put into his or her graveyard.
