Sorcery, 1R (2)
Rare
Each player chooses a card in his or her hand. Then each player reveals his or her chosen card. The owner of each creature card revealed this way with the lowest converted mana cost puts it onto the battlefield.
Illus. Greg & Tim Hildebrandt

10/4/2004: Creature cards which are revealed but are not the lowest cost, or any non-creature cards revealed remain in their owners' hands and stop being revealed.
10/4/2004: You don't have to choose a creature card, but choosing a non creature does nothing except maybe bluff your opponent.
