Tales from the Cryptbreaker

Antoine and Nancy are playing in a standard Grand Prix event. Antoine, who controls three untapped Cryptbreakers, taps one of them and two swamps, draws a card, and marks down one life loss on his note sheet. Nancy stops him to point out the mistake and Antoine replies, “Oops! I meant to draw a card but I activated the wrong ability. I was supposed to tap my two other zombies instead of the lands. Judge!”

Antoine receives a warning for Game Play Error – Hidden Card Error To fix this error, Antoine reveals his hand to Nancy and she chooses one card to be shuffled back into the random portion of Antoine library. Antoine untaps his Cryptbreaker and two swamps and resumes play.
