Step into the enchanting world ofMuster, where players Raise the Banners and seize control of five majestic castles. Strategic planning and bold tactics will determine who emerges victorious in this fast-paced, two-player duel! Assemble a fearsome force drawn from five unique factions, represented by loyal soldiers, agile archers, valiant knights, fierce beasts, and legendary leaders. Unleash the magical power of Rainbow Cards to tip the scales - but beware! Rainbow Wizards are fickle friends whose loyalties can falter when you need them most

InMuster, players draw cards and build up points to control castles. Rainbow cards allow players to hamper the other player, adding a take that component to the duel.

The game immediately ends when the final card has been drawn from the deck. Players then establish who controls each castle by determining who has the most strength icons on the cards on their side of the board under each castle space. The player who controls the most castles wins the game!
