Digimon Alysion Beta Cards: What the Closed Test Revealed About the Game

The Digimon Alysion beta test in August 2025 gave 10,000 players their first hands-on experience with Bandai’s digital card game. What they discovered about how the Digimon Alysion beta cards functioned on mobile devices revealed fundamental problems that sent the game back into extensive redesign. The closed beta exposed serious issues with card visibility, field management, and gameplay mechanics that diverged significantly from the physical Digimon card game.

The Digimon Alysion Beta Test Timeline

Bandai opened applications for the closed beta test in July 2025, selecting 10,000 participants to test the game on iOS and Android devices. The beta launched on August 7, 2025, connecting directly to the Digimon Liberator manga storyline set in the Lacuna metaverse. Players expected to experience the same card game that characters like Kanata Hondo and Futre play in the manga using their D-STORAGE devices.

The beta was meant to validate Bandai’s cross-media strategy, where the manga would build excitement for the digital game while players could experience the world firsthand. Instead, the test revealed that the development team, working under Bandai’s Card Business Department (Carddass) rather than Bandai Namco Entertainment’s video game division, had created a product with serious technical and design flaws.

In September 2025, Bandai published a closed beta test survey report acknowledging the overwhelmingly negative feedback. The company committed to revisions that went beyond their original plans, essentially restarting core aspects of development. As of March 2026, the game remained in development with no release date announced.

Card Display Problems in the Beta

The most immediate problem testers encountered with the Digimon Alysion beta cards was simply reading them. The Digimon card game features complex mechanics with Digimon stacks, inheritable effects, tamer buffs, and option cards triggering from the security stack. The physical game already requires substantial table space to manage these interactions.

Beta testers reported that card text was tiny and nearly impossible to read on smartphone screens. Effects were compressed into small boxes, making it difficult to track what was happening during gameplay. The battle area became a disorganized mess with tamers and Digimon mixed together rather than clearly separated. Players couldn’t easily distinguish between different card types or understand the current board state at a glance.

This wasn’t just an aesthetic problem. In a game where timing and effect resolution matter, being unable to quickly read card text or identify which cards were active created serious gameplay issues. The interface failed to present the information players needed to make strategic decisions.

The Controversial 10-Card Field Limit

The biggest controversy surrounding Digimon Alysion beta cards was Bandai’s decision to implement a hard cap of 10 cards on the field at any time. In the physical Digimon card game, players can have as many Digimon and tamers on the field as their strategy requires. Some decks are specifically built around flooding the board with multiple low-level Digimon or establishing large field presence.

Deck archetypes like D-Reaper and security control strategies depend on having numerous cards in play simultaneously. The 10-card limit fundamentally broke these strategies. When a player tried to play an 11th card, they were forced to trash something already on the field. This wasn’t a minor rule adjustment—it was a complete restructuring of how the game works.

The community reaction was immediate and harsh. Players argued that launching with this restriction would create a watered-down version of the game that existed solely because of poor mobile design decisions. The limitation appeared to be a shortcut to avoid solving the actual problem: designing a UI that could handle the game’s full complexity on mobile devices.

Bandai acknowledged this criticism in their September 2025 survey report, stating they would redesign the battle screen and UI to accommodate more cards. This wasn’t a simple fix—it required rebuilding core systems from the ground up.

Performance Issues Affecting Card Gameplay

Beyond visibility and field limits, the Digimon Alysion beta cards suffered from severe performance problems. Testers reported significant input lag where swiping to play a card wouldn’t register. In a card game where the order of actions and proper timing determine outcomes, missing inputs completely undermines competitive play.

The game ran at approximately 15 frames per second according to widespread reports, making every action feel sluggish and unresponsive. Animations were long and couldn’t be skipped, further slowing down matches. For players familiar with the relatively quick pace of physical matches or competing digital card games like Yu-Gi-Oh! Master Duel, the experience felt painfully slow.

These technical issues compounded the UI problems. Not only were cards hard to read, but interacting with them was frustrating and unreliable. The combination made even basic deck testing difficult.

Deck Building Challenges

Building decks with Digimon Alysion beta cards proved to be another major obstacle. Beta testers reported that the deck building interface was confusing and difficult to navigate. Many players simply gave up and relied on pre-built decks rather than attempting to construct their own strategies.

For a card game, this is a critical failure. Deck building is where players express creativity, adapt to the meta, and develop personal strategies. If the interface makes it too frustrating to build decks, players can’t properly test card combinations or develop the game’s strategic depth. The physical Digimon card game has a thriving competitive scene specifically because of the diverse deck building options available.

The deck building problems meant that even if specific strong cards existed in the beta, players couldn’t easily access them or experiment with different combinations to discover optimal strategies.

Matchmaking and the Multiplayer Experience

Digimon Alysion beta cards were tested in a multiplayer environment with broken matchmaking. The system frequently matched players against the same opponent multiple times in a row or paired players at completely different skill levels. This made it difficult to get meaningful feedback about card balance or deck performance.

A digital card game’s matchmaking system is crucial for creating fair, competitive matches and keeping players engaged. When matchmaking fails, even well-designed cards and balanced mechanics can’t salvage the experience. Players can’t properly evaluate whether their deck and card choices are effective if they’re constantly facing mismatched opponents.

The Development Structure Problem

Understanding why the Digimon Alysion beta cards and overall game had so many issues requires examining who’s building it. The game is being developed by Bandai’s Card Business Department (Carddass), which specializes in physical trading cards, toys, and vending machines. They produce the physical Digimon card game along with the One Piece and Dragon Ball Super card games.

However, Carddass isn’t a video game studio. Building a complex multiplayer cross-platform digital card game requires expertise in server architecture, matchmaking algorithms, mobile optimization, and UI design. When a physical card division attempts to build a digital game in-house or outsources to a smaller mobile developer, the result is often exactly what happened with Digimon Alysion: ambitious ideas with poor technical execution.

By contrast, Yu-Gi-Oh! Master Duel was built by Konami’s dedicated digital entertainment division and became a polished, worldwide success. Even within Digimon properties, Bandai Namco Entertainment released Digimon Story: Time Stranger in October 2025 for consoles and PC to critical acclaim, demonstrating that the right development team can absolutely create quality Digimon games.

Current Status and Pre-Registration

At Digimon Con in March 2026, Bandai showed a redesigned battle screen that addressed some of the beta’s UI problems. They announced that player-versus-player with friends would be added and confirmed work on additional language support. However, they provided no release date or even a rough timeframe.

As of October 28, 2026, pre-registration is now available on the App Store and Google Play, suggesting the game may finally be approaching launch. The official site describes Digimon Alysion as a free-to-play online card game with in-app purchases for mobile platforms.

The game’s connection to the Digimon Liberator manga continues, with players able to experience the Lacuna metaverse and encounter characters like Kanata Hondo and Valner Dragnogh. Whether the final version of Digimon Alysion cards will properly translate the physical game’s complexity to mobile devices remains to be seen.
