Players can choose 8 cards from their own library to form their own "playing cards". Players can save up to three decks of cards and then choose a deck of cards they want to play. Click "Match" in the matching interface to search for opponents, and the matching system will search for other players with a similar number of trophies to that player. The number of cards a player has will not affect the game.

At the beginning of the battle, the cards selected in this deck will appear randomly in the card slot (four cards will appear in the card slot at the same time, and the next card will appear next to the card slot). Each player will initially have 5 drops of holy water (the holy water will increase with time, and the maximum storage capacity of holy water is 10 drops). Summoning different cards will consume different holy water.

Dragging cards in wartime consumes holy water to summon cards to fight in positions. In the early stage, you can only summon your own position. If the princess tower is pushed off the enemy's wings, the calling range can be expanded.

There are 1 king tower and 2 queen towers on both sides. Destroy 1 Queen's Tower and gain 1 Crown. Destroy the King's Tower (main tower) and gain all three crowns. Each game lasts for 3 minutes. After 3 minutes, the draw was extended 1 minute. At the end of the game, the party with the most crowns wins, destroying the King's Tower and winning the game directly.
