Your goal in life is to become the world's greatest monster breeder. In order to do this, you must travel around the world, challenging other breeders to card matches. If you win, you will collect more cards. If you can pass all of the license matches and collect all 100 cards, you will join the ranks of the master breeders. Before every match starts, each contestant presents a team of monsters and draws five cards (the cards are used to attack the team of monsters). However, if you don't like the cards you've drawn, you can discard some but that will award your opponent Guts Points. Every card requires a certain number of Guts Points to use, so discarding too many cards will give your opponent an advantage. Try to keep all of this in mind as you fight to become a master breeder in MONSTER RANCHER BATTLE CARD GB.
