Where the information comes from
Nothing on TCGenius is invented. Each kind of information has a named source, and prices and ban lists are re-read on a schedule.

| Yu-Gi-Oh! rulings | Yugipedia's card rulings pages (CC BY-SA 4.0) |
| Yu-Gi-Oh! ban lists | Konami's official TCG list; Yugipedia's record of the OCG list; Master Duel Meta for Master Duel |
