Spellbinder

Spellbinder is a Magic: The Gathering deck builder, card database and collection manager. Connect it and Claude can search the full card catalog by name, rules text, type, color, legality and price. It can look up printings and rulings, find the cheapest tournament-eligible printing of a card, browse sets and preconstructed decks, and research tournament events, decklists, archetypes and metagame summaries. Once you sign in, Claude can also read your decks, collection, wishlist and profile. It can analyze a deck for legality, ownership and market value, rank and summarize your collection, track set progress, and compare recent Standard tournament decks against your Paper collection and a budget. Claude can add to your account but never take away from it. It can save a new deck from a decklist and add cards to your collection or wishlist. It cannot edit or delete anything you already have. Prices are market estimates that update daily. When a card has no current price, Spellbinder says so rather than guessing.
