You play as a newcomer in the Tournament whose goal is to rise to the rank of Champion.

You and your opponent get five cards which you must place on a 4x4 board. You can attack and capture the other player's cards depending on where they're placed and their attack and defense power.

At the end of each round, the player who has the most cards in his possession wins. You can get new cards throughout the game and gain experience to make them stronger. The rules are detailed in the tutorial.
