Yu-Gi-Oh! (3-in-1 Edition) Vol. 10-12 (manga)

The diabolical Player Killer, Pegasus’s second gaming assassin, challenges Yugi to a Shadow Game! In the shadow of the Castle of Dark Illusions card, an army of lurking monsters hungers to steal Yugi’s life points—and if he loses, his actual life! Then the action moves into underground tunnels beneath Duelist Kingdom. There Yugi and Jonouchi must conquer the maze of the Meikyu Brothers in a two-on-two duel. Waiting in the Brothers’ deck is the Gate Guardian, lord of the underworld and one of the most powerful monsters of all.
