Siege-Clan War CCG set

 Siege: Clan War  was a self-contained cooperative variant of Legend of the Five Rings Card Collectible Game, with multiple players opposing a challenge deck piloted by another player. The Yogo Junzo challenge deck included new cards with no arc legality; the three pre-constructed decks included cards legal throughout the Twenty Festivals arc, from Ivory Edition through Evil Portents, 9 new cards and one reprinted card, Productive Mine, with Onyx legality only. It depicted the era of the great Clan War, being opened the Black Scrolls, and the forces of the Shadowlands having an alliance with the Crab Clan in an attempt to gain entrance into the Empire.
