FaBrary is an online toolkit for Flesh and Blood players, bringing card search, deck building, and collection management together in one place. Users can search the card database, create or import decks, organize personal and favorite decks, and browse public, tournament, preconstructed, and Metafy decks. Deck comparison tools help players review different lists, while hero and statistics pages provide additional ways to explore the game’s cards and deck landscape. FaBrary also features meta results and lists of the most-played decks, supporting players who want to follow current deck trends.

Beyond deck and collection features, the site offers tools for card overlays, drafting, calculating clash outcomes, estimating hypergeometric probabilities, tracking graveyard and banished cards, and linking with Talishar. Its community section includes content creators, submitted content, and integrations such as Discord and Reddit bots. Players can also find information about sets, bans and restrictions, and Living Legend status. FaBrary states that it is not affiliated with Legend Story Studios, the publisher of Flesh and Blood.
