Was looking at the Zendikar Spoilers and noticed this card:
Sadistic Sacrament BBB
Sorcery
Kicker (You may pay an additional as you cast this spell.)
Search target player's library for up to three cards, exile them, then that player shuffles his or her library. If Sadistic Sacrament was kicked, instead search that player's library for up to fifteen cards, exile them, then that player shuffles his of her library.
Thatsa lot of cards to exile What happens if other player doesnt have enough cards in his library?
