Illegal

If a card is Illegal, it means it cannot ever be used in tournament play or other official Duels. Illegal cards may only be used in casual play at the agreement of all participants. In general, official cards which are illegal can be distinguished by the presence of limitation text (most commonly "This card cannot be used in a Duel.") where the password would be normally placed, in the card's lower left-hand corner. All unofficial and counterfeit cards are also Illegal.

Anime

It is mentioned that "Golden Castle of Stromberg", "Infernalvania", and "Restraining Sword of Impact" are Illegal cards not intended for use.

In Yu-Gi-Oh! ARC-V it is shown that if an Illegal card is used, the Duel will automatically end. The same rule applies in Yu-Gi-Oh! SEVENS.
