The Least of Gold Rings

Bearer must make a corruption check at the end of each of his untap phases. Discard this ring when tested. If tested, obtain a random value to determine which ring card may be immediately played: The One Ring (12+); a Dwarven Ring (10, 11, 12+); a Magic Ring (1, 2, 3, 4, 5, 6, 7); a Lesser Ring (any result).
