A voice from the crew.
Responsibility with the project.

Player guides and app help have different jobs.

Our Yu-Gi-Oh! guides explain game and deck-building ideas without requiring a CHAINZERO account or familiarity with the app. Our Help section covers specific app screens and steps. Optional product links are labeled as such.

Characters bring the voice. They are not credentials.

CHAINZERO editorial is the project’s publishing label. The Architect, Vector, and The Night Reader are fictional CHAINZERO characters used as narrators. They are not separate people, professional players, accredited judges, or official Konami representatives.

These guides were drafted with AI assistance and checked against the linked official resources and, for app help, the current interface. Character artwork was also AI-generated. We do not claim an independent human expert reviewed a page unless a real review and its scope are identified.

Sources, examples, and limits stay visible.

Rules and card claims should link to relevant official sources. Commentary is our interpretation; event judges and official documents control. A third-party report can help us discover a topic, but it is not automatically proof of a ruling, regional release, or tournament result.

Opening-hand examples use our own tested calculations. Starter access is not a complete brick-rate or win-rate prediction. An illustration or worked example does not prove a combo works in every situation.

App screenshots use example workspaces. They show the steps being discussed and are not testimonials, usage statistics, or evidence of a player’s actual collection.

Dates should mean something.

We keep stable article URLs and update dates when content changes or is substantively reviewed. Rebuilding the website alone does not make an article newly reviewed.

For future card news or named-combo analysis, we will distinguish confirmed details from interpretation, announced releases from currently playable cards, and card catalog coverage from checked app support. We will not publish a claim of universal format or matchup coverage.

Help us make a note better.

CHAINZERO is independent and is not affiliated with or endorsed by Konami. Our content is not an official ruling, coaching credential, or guarantee of tournament legality.
