- When "Castle of Dark Illusions" was released, it gained a different background, compared to its manga artwork. Also, in the international version of the anime, the Kanji "闇" was removed from its ring, although it was kept in the TCG version of the card. In Yu-Gi-Oh! Duel Monsters and Yu-Gi-Oh! Duel Monsters II: Dark duel Stories, this card has another different background.
