they reveal a land card; If an opponent reveals
only one card, draw a card; If an opponent reveals
five or more cards, create two 2/2 Black Zombie creature tokens; If an opponent reveals ten or
more cards, put a creature card from among them
onto the battlefield under your control. All
revealed cards are put into the graveyard.
