Lelouch

The goal of the Usurper is to personally eliminate the King and get his role card. When this happens, both the King and the Usurper switch their role cards. If the Usurper's life total becomes the King's starting life total, the King doesn't lose the game; instead, the King's life total becomes 1, and all commander damage and poison counters are removed from it. The King's new goal is to "usurp the Usurper," while the Usuper's new goal is to win the game as King.
