Grimoire is where your card collection lives, and where your next deck comes from. SCAN YOUR CARDS IN Point the camera at a card and it goes into your collection — set, printing, finish and condition. No typing, no spreadsheets. BUILD FROM WHAT YOU ALREADY OWN Your collection is the starting point, not an afterthought. See what you own as you build, and what a deck would actually cost you to finish. A FAMILIAR THAT SHOWS ITS WORK Your Familiar is a companion that builds a deck with you, one piece at a time. Every card it suggests comes with a reason. Every cut waits for your say-so. When it leans on a rule, it cites the rule. KEEP TRACK OF WHAT IT'S WORTH Your collection carries real prices, so you know what you're holding — and what you paid for it, kept honest and separate from what it's worth today. EVERYTHING IN ONE PLACE Wish list, binders, condition, language, notes. Search every printing of every card. Your decks and your collection stay in step, on your phone and on the web. Free to start.
