Since Dark Yugi hoped to win all eight of Mai ' s Star Chips , but only had six of his own to wager , he also put his life on the line . The Player Killer was skeptical that Dark Yugi would hold to that end of the deal , so he shot a wire out of his Duel Disk , which wrapped around Dark Yugi ' s neck .
