About This Game

Forge Your Deck. Reclaim the Lost Constellations.

The stars above the academies are going dark, one by one—and the memories bound to them are disappearing. Choose your academy, build a 30-card deck, pursue the sealed archives, and uncover the truth behind the theft of the stars’ memories.

Build Your Own Strategy

Combine followers, spells, and weapons from a launch pool of 168 active cards. Create powerful chains around your academy skill while managing mana, positioning, and the timing of every attack.

Master Six Academies

Command the powers of Fire, Water, Wind, Earth, Light, and Shadow. Each academy offers a distinct hero skill, card synergies, and deck-building identity. Find the strategy that suits you, then collect new cards and experiment with different academies and combinations.

Reshape Cards with Startraces

Fuse duplicate cards into your favorites and engrave them with permanent Startraces. Combine Bonds, Destinies, and Boss Imprints to transform even an ordinary card into the centerpiece of your deck.

Challenge the Stolen Memories

Journey through an eight-chapter story campaign spanning 60 nodes. Face eight bosses with unique mechanics and multiple phases as you reclaim the memories scattered across the stars.

Choose Your Challenge

Beyond the main Star Map campaign, several additional single-player modes await:

• Roguelike Adventure: Explore eight floors of randomized trials across three difficulty levels. Choose your path, gain temporary blessings, and push deeper with every battle.

• Free Battle: Choose any academy and deck, then jump straight into a standalone battle against the AI.

• Eight Sovereigns — Boss Rush: Unlocked after completing the campaign. Challenge all eight bosses with a single deck while Health carries between battles. Choose one field supply after each victory and face a different boss order in every run.

• Astral Arena: Unlocked after completing Chapter 1. Reach seven victories before suffering three defeats, battle increasingly powerful opponents, and earn a rank chest based on your final record.

Play at Your Own Pace

Phantom Cardia: Astral Card Duel is a fully offline, single-player deck-building card game. The full game is a one-time purchase, with card packs and resources earned entirely through play—no forced advertisements, paid card packs, or daily-task pressure.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Pre-generated AI-assisted visual content is used in this game. AI was used to create and iterate on card illustrations, character portraits, backgrounds, icons, and selected promotional artwork. AI was used to generate source video clips for pre-rendered chapter cinematics. These assets were selected, edited, composited, cropped, color-adjusted, and integrated by the developer. The game does not generate AI content during play, does not accept player prompts, and does not connect to an external AI service at runtime.
