What it is
It is a free mobile card game. You digivolve, break five security cards, and memory ends your turn. Costs and effects resolve automatically.
Digimon Alysion is the mobile card game. You digivolve by stacking cards, break five security cards, then hit the player. Memory is the turn clock: pay a cost and the counter moves toward your opponent, and your turn ends when it reaches 1 or more on their side.

Digital, not a scanner app
The system page's fourth point is the product difference. Cost is tracked for you. Effects resolve for you. Unsuspend at the start of your turn and the draw are also automatic. You still choose the breeding action and the main-phase order.
| Paper habit | What the app page says happens |
|---|---|
| Track memory by hand | The counter moves when you pay a cost. |
| Resolve each effect yourself | Effects activate and resolve automatically. |
| Remember to unsuspend and draw | Those two steps run on their own. |
| Learn from a friend | Story Mode walks Kanata through the rules with Futre. |
Price on the game site is free, with in-app purchases. The promo also notes loot boxes. The Japan store listing adds a free pack each day. None of those posts print pack odds.
New cards, same spine
The [BD-01] trailer says the set is available at release and names new cards Gemmon, Rubeusdramon, and Kanata Hondo beside familiar ones such as Agumon and WarGreymon. That is a contents teaser, not a rulings page. Color roles, DP, and inherited effects are on cards and colors.
Story Mode is the other half of the pitch: a new thread in the Liberator setting, not a replacement for the comic. The world page links that comic from the game site.
