How to play

Digimon Alysion is the Digimon Card Game played as a mobile app, with an original story used as the tutorial. The official system page explains memory, security, digivolving and colors. It says the battle area has a cap and does not print the number.

What the diagrams show

Start with a 50-card main deck, up to 5 Digi-Egg cards, and at most 4 copies of the same card number. A different number is a different card even when the Digimon name is the same. These are the app rules printed on the official SYSTEM page.

  1. Unsuspend: suspended cards in your battle area become ready automatically.
  2. Draw: draw one card; the first player skips this on their opening turn.
  3. Breed: choose one action: hatch a Digi-Egg, move a Digimon with DP into battle, or do nothing.
  4. Main: play or digivolve Digimon, play Tamers, use Options and attack in an order your cards allow.
  5. End: paying costs moves memory toward your opponent; once it reaches 1 or more on their side, your turn ends.

Digivolving stacks cards and can unlock inherited effects. To win, break through the opponent’s 5 security cards, then attack the player directly. The app manages costs and resolves effects automatically.
