Card data on Grimoire is never paywalled. Card search, deck browsing, collection import, and viewing shared decks are all available with a free account or, for public decks, with no account at all. Paid plans exist only to cover the cost of AI deck generation.

Popularity, inclusion rates, and synergy statistics used to guide recommendations come from publicly available EDHREC data. Grimoire is not affiliated with or endorsed by EDHREC.

Prices shown are estimates from public pricing data and can lag behind the live market. Treat them as a rough guide for budgeting, not a quote. Always check the retailer's own page for the current price and availability before buying.

Some links to TCGplayer and Card Kingdom are affiliate links. If you buy through one, Grimoire may earn a commission at no extra cost to you. This never affects which cards we recommend — recommendations are generated before any pricing or purchase links are attached.

Deck lists and strategy write-ups are generated by an AI model from Anthropic, working from the card data and statistics above. Singleton, colour identity, and ban-list rules are then verified in code rather than trusted to the model. Recommendations are suggestions only — no guarantee of performance or of legality for sanctioned play is made or implied.

Format legality information is provided for convenience and comes from third-party data. Absolutely no guarantee is made. For sanctioned events, confirm your deck with a local judge or with Wizards of the Coast customer service.
