Hey Product Hunt! I’m Quentin, maker of Manamatch. I built it after seeing the same problem in Magic playgroups: someone buys cards for a deck, then discovers a friend already had them sitting in a binder. Mana Match gives each player their own collection, then lets a trusted playgroup: - import an existing ManaBox collection - share collections privately or publicly - paste a decklist and see what the group already owns - see who has a card for borrowing, giving, or trading It isn’t trying to replace deckbuilders or collection apps. It is the shared layer between the cards your friends own and the deck you want to build. I’d love feedback on one question: would you use this with your Commander/MTG playgroup, and what would make it useful enough to invite your friends?
