mtgmatic: A Commander Deck Builder With a Rules Engine
A Commander deck builder that imports lists, checks legality, prices cards against your collection, and playtests decks against an AI rules engine.
Field notes
The workflow accepts pasted lists or MTGO .dek files, resolves names against Scryfall, and returns legality, collection, pricing, and deck-statistics information. The page cites Commander-specific checks such as singleton, color identity, banned cards, and commander validity. Its playtest mode remains in beta, with a stated supported pool of 1,379 cards and three curated decks; the changelog is offered as the record of additions. The site also separates those beta features from the claimed non-beta builder, pricing, and collection functions.
