Every card. Always current.
Card Database
A comprehensive database with every Yu-Gi-Oh! card ever printed, updated daily. Automatic sync and complete offline access.
A Yu-Gi-Oh! card database is the structured index of every card ever printed — name, effect text, attribute, type, level, ATK and DEF, archetype, ban-list status, plus every set, set code, rarity, and edition the card has appeared in. YuScan ships with the complete database on-device, refreshed daily, and accessible without an internet connection. The same data feeds the scanner, the deck builder, the collection tracker, and the public website at yuscantcg.com.
Coverage spans the full TCG and OCG release history. Every printing back to the original Legend of Blue-Eyes White Dragon (2002) is indexed, including alternate art variants, World Championship promos, Duel Terminal foils, sneak peeks, and tournament participation cards. New releases are added within 24 hours of their official Konami publication and propagated to every device on the next sync.
The database is the foundation that everything else in YuScan rests on. Without an accurate, comprehensive, daily-refreshed database, the scanner would misidentify cards, the deck builder would validate against stale ban lists, and collection values would drift. Investment in the data pipeline is the unglamorous work that makes the user-facing features actually work.

How the YuScan Yu-Gi-Oh! database works
The database is built by aggregating, deduplicating, and cross-referencing several authoritative public sources. Card metadata (effect text, attribute, type, level, ATK and DEF, archetype, ban-list status) starts from the open YGOPRODeck dataset. Printing-level data — set codes, rarities, alternate arts, 1st Edition versus Unlimited variants — is matched against marketplace listings from TCGPlayer and Cardmarket so that every printing in the database corresponds to a real product a player can actually buy.
Updates are continuous on the server side and daily on the device side. The server-side pipeline reconciles new releases, banlist revisions, and pricing changes hour by hour. Each user device syncs once per day (or on demand) by downloading a compressed delta — typically a few hundred kilobytes — and merging it into the local database. The full initial database download is under 30 MB compressed; subsequent updates are an order of magnitude smaller.
Multilingual data is first-class. Every card carries its name and effect text in English, French, German, Italian, Portuguese, and Spanish where Konami has published an official translation. The scanner is language-agnostic (it matches artwork rather than text), so a German player scanning a French card sees the result in their preferred display language without having to switch settings.
When to use the YuScan database
Use it as a reference whenever you need to confirm a card text, ban-list status, or printing detail. Tournament players double-check rulings against the database mid-game. Collectors verify whether a card they were offered is actually a 1st Edition or an Unlimited reprint. Returning players use the archetype browser to discover what new families exist in the seven years they were away.
Use the offline access when connectivity is unreliable. Locals at a card shop with a broken router, regionals in a basement convention hall, packed events where mobile data crawls — all the places where you most need the database are exactly the places where you cannot rely on the network. YuScan ships the full dataset on-device for this reason.
Use the website mirror at yuscantcg.com when you are at a desktop. Every card, archetype, and expansion has a permanent URL with the same data the app shows, so you can link to a card in a Discord channel or a deck-tech article and the link is stable.
Frequently asked questions
How many Yu-Gi-Oh! cards are in the YuScan database?
The database covers every Yu-Gi-Oh! card ever printed in the TCG and OCG, plus alternate-art variants, World Championship promos, and other limited releases. The exact card count grows with every new set release; at the time of writing the database holds tens of thousands of unique printings across hundreds of expansions.
Does the database work offline?
Yes. The full card database, archetype index, expansion data, and ban-list state are all stored on your device after the initial sync. Search, browse, deck building, and collection tracking work with no internet connection. Live pricing is the only feature that requires a network call.
How often is the database updated?
Server-side updates run continuously, with new cards added within 24 hours of an official Konami release. Devices sync daily by default, downloading a small compressed delta rather than the full database. A manual refresh is available in the app settings whenever you want to force an immediate sync.
How big is the database on my device?
The full database is under 30 MB compressed on your iPhone. Daily delta updates are typically a few hundred kilobytes. The on-device storage footprint is negligible relative to anything else on a modern phone, including a single Yu-Gi-Oh! tournament photo.
Are alternate arts and rarity variants tracked separately?
Yes. Each printing — including alternate art, foil, 1st Edition, Unlimited, Quarter Century Secret Rare, and other variants — is a distinct row in the database with its own set code, rarity tag, and price feed. Searching for a card name returns every variant; the scanner picks the specific variant that matches the photographed card.
What languages are supported?
Card names and effect text are available in English, French, German, Italian, Portuguese, and Spanish. The display language is a per-user setting; the underlying data is the same. Cards without official translations in a given language fall back to English.
