It's time to battle! Use your favorite monsters from Monster Rancher and watch the magic unfold as you engage in combat against your opponent. You inhabit a secluded island and it is up to you to collect all the cards on the island before your opponent has a chance to. Make your monster more powerful by collecting cards to destroy your challenger. As the game progresses and your monsters gain strength, you become eligible to take part in "License Matches" at the arena.
