Grimoire: MTG Deck Builder

Grimoire builds legal, mana-curve-balanced 99-card Commander decks from the cards you actually own — no guesswork, no proxies required.

HOW IT WORKS • Add your collection • Pick a commander — search from every legal commander in Magic's history • Choose a strategy, or just describe what you want in plain English • Get a complete, legal 99-card deck with the reasoning behind every pick

BUILT FOR REAL DECKBUILDING • Full legality checks against the Commander banlist and color identity • Mana curve and synergy analysis, not random card dumps • Automatic combo detection — see the two- and three-card combos hiding in your list • Deck stats at a glance: land count, average mana value, and power bracket • Track your collection's stats — total cards, unique cards, and more

AI DECK BRIEF (PREMIUM) Describe the deck you want in your own words — "aggressive red-white tokens" or "grindy control with a wrath finisher" — and get a tailored build with an explanation of the strategy behind it.

FREE TO START Grimoire is free to download and use. Build and save up to 3 decks at no cost. Premium unlocks unlimited saved decks and the AI Deck Brief, available as a monthly or annual subscription.

Whether you're building your first Commander deck or your fiftieth, Grimoire turns your binder into a battle-ready 99.
