JudgeDeck

JudgeDeck is a mobile + web AI rules assistant for collectible and competitive card games that constantly cause arguments: timing, priority, stack interactions, replacement effects, and edge-case wording. Players snap a photo of the board state and relevant cards, then describe the question in one sentence. The app returns a ruling with citations (official rules sections, oracle text, and known judge notes), plus a short “why” explanation and a confidence score. It also generates a shareable ruling link for your table or Discord, and saves your game’s state as a “case” so you can revisit it later. This is not a deckbuilder or a full game client; it’s a referee. Realistically, it will only work well for a few games at first (e.g., Magic: The Gathering, Pokémon TCG, Yu-Gi-Oh!) because rules ingestion and card databases are heavy. Monetization: freemium with limited rulings/day, plus a judge/tournament organizer plan.
