Data sources and affiliation

DeckScope is an independent analysis and collection-management tool.

It is not an official card database, tournament authority, marketplace, or publisher-operated service.

What DeckScope provides

DeckScope adds an operational and analytical layer:

• inventory organization
• deck readiness
• acquisition planning
• deck analysis
• comparison and suggestions
• public-source navigation where available

Official references

When official card or product references are available, use them as the authority for official text, legality, product details, and event-specific rules.

DeckScope should make source context visible where it matters, especially for card detail, format, legality, and product pages.

In particular, treat the publisher’s own card database and the official banlist announcements as authoritative over anything shown here for:

• printed card text and rulings
• current forbidden and limited status
• product contents, set codes, and release dates
• event and tournament policy

Where DeckScope and an official reference disagree, the official reference wins and the difference is a bug worth reporting through the Support page.

Pricing data

Pricing can be incomplete, stale, estimated, or based on placeholders depending on source availability.

Always verify expensive purchases against the actual seller, shipping, language, condition, and checkout total.

Non-affiliation

DeckScope is an independent collection-tracking and deck-management tool. Yu-Gi-Oh!® and all related card names, characters, and properties are trademarks of their respective owners. DeckScope is not affiliated with, endorsed by, or sponsored by Konami Digital Entertainment.

The same posture applies to every other third party whose data or links appear here: DeckScope is not affiliated with or endorsed by official databases, marketplaces, or tournament platforms unless explicitly stated.

Card data, images, and text shown in DeckScope are used descriptively to identify cards within your collection and decks, in the same way a price guide or collection tracker for any trading card game would. No card artwork, effect text, or Konami trademark is used to imply sponsorship or an official partnership.

If you are a rights holder with a concern about how your property is represented, contact us at hello@deck-scope.com and we will respond promptly.

The canonical statement lives on the marketing site at Non-affiliation. This page carries the same posture; if the two ever diverge, the linked statement is authoritative.
