Rulebook and Brackets/Game Changers reference are bundled with this app. Card lookups pull live Oracle text and official rulings from Scryfall — Claude vision only reads a card's name off a photo. Live lookups need normal network access, so they won't work inside this chat preview; open the downloaded file as a webpage (or host/wrap it) to use them. Saved Rule 0 cards are stored privately for you and aren't visible to other users of this app.
