What's Free
Everything here is free. Scanning, deck suggestions and Pro Analysis are the parts with a real running cost behind them, so here's how they work.
Card Scanning
Scan cards with your phone and review the matches in your queue. Scanning is free and unlimited.
Deck Suggestions
Get four suggested cards in the deck builder, then refresh when you want a new set. The app reuses suggestions while you edit your deck.
Pro Analysis
Get a full deck review on the Stats page, including cards worth adding or cutting and the reasons behind each recommendation.
Access
Deck suggestions and Pro Analysis are free, with no monthly usage limits for verified accounts. Verify your email after signing up to activate your account.
Where the Suggestions Come From
Suggestions and Pro Analysis look at your deck contents, your commander, and, for Pro Analysis, your collection. Every card they suggest comes from the card database, so a suggestion is always a real card that really exists.
They can still be wrong about whether a card is good in your deck. Treat them as a second opinion, not a deckbuilding oracle, and if one makes no sense to you, trust yourself. The Technology page has the details of what runs underneath.
