The whole TCG stack, one system.

DeckardGains identifies MTG, Pokémon, and One Piece cards from your camera — including foils, alt arts, etched finishes, and reprints across sets — then powers your live stream overlay. Import from ManaBox, TCGPlayer, or any CSV.

Multi-TCG — Not just Magic

Most competitors only support MTG. DeckardGains handles three games natively with game-specific metadata:

Magic: The Gathering

Mana cost, type line, color identity, foil/etched/alt art detection

Pokémon TCG

HP, energy types, full art / alt art / secret rare identification

One Piece TCG

Power, counter, color, leader vs character distinction

AI-Powered Scanner

Point your camera at a card — our LLM vision engine identifies name, set, rarity, foil status, and condition in seconds.

Foil & Variant Detection

Regular foil, etched foil, textured foil, showcase frames, borderless, extended art, and reprints across different sets.

ManaBox & TCGPlayer Import

Export from ManaBox or TCGPlayer, upload the CSV, and all cards merge into your unified collection automatically.

Merge by Variant

Cards are matched by (name + set + foil + condition). Duplicates merge quantities — no manual dedup needed.

Batch Scanning

Scan multiple cards in a session. Identified cards auto-save immediately; unmatched ones are flagged for manual review.

API Integration

Push cards from any external scanner via REST API. Get your tcgt_ key from Settings and POST to /api/import/singles.
