Kaiba heads off to Pegasus’ retirement castle, and challenges him to a duel. If Pegasus wins, he gets Kaiba’s Blue-Eyes White Dragons, but if Kaiba wins, Pegasus hands over the card that can beat the Egyptian Gods. Kaiba wins, and Pegasus fulfills his wager, giving two cards to Kaiba. However, Pegasus only created one card, so where did the other one come from?
