Ability
Ganryū-jima. Always defeats epics and legendaries; against the rest, a normal fight. The card it defeats is banished along with all its copies, wherever they are.
The myth
Born around 1584 in the twilight of the Sengoku wars, Miyamoto Musashi killed for the first time at thirteen and never lost again. A masterless rōnin without land or lord, he crossed Japan testing himself in more than sixty duels: alone he broke the Yoshioka school beneath the pine of Ichijō-ji, and he cut down Sasaki Kojirō on the island that now bears the loser's name. When the country finally quieted and his trade ran out of enemies, he withdrew to the cave of Reigandō and turned the blade inward: there he wrote the Book of Five Rings, painted shrikes in ink, and set down twenty-one precepts of solitude. He died in 1645, leaving two swords, a brush, and a doctrine no one has yet exhausted.
