One app, two superpowers. Pick a commander and let AI build you a complete, legal 100-card deck. Or point your camera at any Magic: The Gathering card and get a clear, plain-English answer to what it does, what every keyword means, and the gotchas that trip players up.
BUILD A COMMANDER DECK IN MINUTES
Choose a commander, set a power bracket, cap the budget, and describe your strategy in your own words: "goblin tribal", "pillow fort", "lands matter". Moments later you're looking at a complete Commander/EDH deck, ready to play: 100 cards, legal, on budget, true to your commander's colors, organized by role (ramp, removal, card draw, wincons, synergy), with a game plan that tells you how the deck wants to play.
BUILT FOR YOUR TABLE'S POWER LEVEL
The builder enforces WotC's Commander Brackets for real, Game Changer limits and combo rules included, so a bracket-2 deck really is a bracket-2 deck, and the deck you bring matches the table you sit down at.
MANAGE YOUR WHOLE DECKBOX
Already have a decklist? Paste or scan it in, no AI needed, and it's auto-organized by role (ramp, removal, card draw, wincons, synergy) just like an AI-built one. Build or edit any deck's cards by hand too, entirely free, with suggestions pulled from real synergy data for your commander. A background watcher keeps an eye on Commander's banned and restricted list, notifying you the moment a card in one of your decks changes status. And every AI explanation and game plan stays grounded in the card's real oracle text, rulings, and the Comprehensive Rules, not a chatbot guessing from internet folklore.
SCAN ANY CARD, UNDERSTAND IT INSTANTLY
Point the camera at a card: recognition is automatic, no shutter, no typing. Oracle text, rulings, market prices, printings, and format legality appear free with no AI call, and one tap gets you a plain-English explanation of what the card does and how it's actually ruled.
TWO-CARD INTERACTIONS
Do these two cards combo, or does one shut the other down? Scan both and ask. You get the stack interactions, replacement effects, state-based actions, and tournament edge cases reasoned out step by step.
ASK ANYTHING
"Can I respond to this spell?" "Does my creature survive -2/-2?" "How do two triggers stack?" Type any rules question and get an answer tailored to your board. Ask in your language and the answer comes back in it too.
MAGIC, WHEREVER YOU ARE
Card of the Day and Today's Commanders widgets on your Home Screen. Siri answers rules questions hands-free. Your cards and decks show up in Spotlight search. And the full Comprehensive Rules travel with you, searchable offline in the Search tab.
A NOTE ON AI AND PRIVACY
AI deck building and explanations are generated by Google's Agent Platform (Gemini). You are asked to opt in before anything is sent, and you can review or revoke this any time in Settings. Card scanning, oracle text, rulings, prices, and combos do not require AI.
