CardAdvantage is a collection manager and deck builder for Magic: The Gathering players. It works offline, has no account to create, and builds decks with an AI model that runs on your own hardware.
For Android, Windows, and Linux. The Linux build is out now; Android and Windows are not available yet.
Pick a format, describe the deck you want, and the AI Architect drafts a list you can review card by card before applying it. By default the model runs on your own device, so your prompts stay there too. AI suggestions can be wrong: check legality and rulings yourself.
Import from Moxfield, Archidekt, ManaBox, Deckbox, or TCGplayer CSV exports, or scan cards with the camera on Android. Sync the card catalog once and search it without a connection. Double-faced cards show both sides.
See what a deck is worth in USD or EUR, which of its cards you already own, and what the rest cost. Send the missing cards to TCGplayer, Mana Pool, or Cardmarket.
A deck is checked against its format’s rules as you build it, every card shows its legality format by format, and you can draw sample opening hands to see how a deck starts.
Keep life totals for the whole pod, record who won, and let each result feed that deck’s record.
Color identity, mana curve, and creature-type breakdowns, plus snapshots of what your collection is worth over time.
Your collection, decks, and match history are stored in a database on your device and are never sent to us. Card data and images come from Scryfall. The Privacy Policy lists everything that does leave the device, and Deleting your data explains how to erase it all.
