• The runes around the rim of the Seal are Enochian and spell out "Oreichalcos" twice.
    • In the Japanese anime, the text on all "Orichalcos" cards are also written entirely in Enochian runes, except for "Orichalcos Sword of Sealing" (incidentally, the only "Orichalcos" card that Dartz did not use).
  • This was the first card to prevent the user from Special Summoning from their Extra Deck as a means of balancing its power. Later cards have since picked up on this, such as "March of the Monarchs".
  • This is the first anime-original card to have been a TCG exclusive card.
  • Konami has pointed out that the number of sentences of text on the TCG print of this card matches the number of lines and points in this card's symbol.[1]
  • This card's effects are all based on its appearances in the anime.
    • This card's first effect, the 500 ATK boost, is the only one identical to its anime counterpart.
    • Its second effect, not being destroyed once per turn, was displayed in the anime when Yugi tried to destroy Gurimo's copy with "Dust Tornado"; while Gurimo claimed the card could not be destroyed at all, since it was never attempted to be destroyed again, Konami asserts that Gurimo was intentionally deceiving Yugi.[2]
    • Its third effect, limiting your opponent's choices for attacking your monsters, is a twist on its anime counterpart's effect to prevent the opponent from attacking monsters placed in the Spell & Trap Card Zone by its other effect. This effect is identical to that of "Pixie Ring", which Konami pointed out when announcing it.[2]
    • Its fourth and fifth effects, preventing the user from Summoning monsters from the Extra Deck and destroying Special Summoned monsters, is based on what happened when this card was played by Yami Yugi, destroying "Dark Magician Girl the Dragon Knight" and reverting it to its unfused state, and the fact that Yugi, Dartz, Rafael, Valon, and Alister did not Fusion Summon after it was activated[3] (notably, Rex Raptor did Fusion Summon "Horned Saurus" while controlling "The Seal" in episode 161).
    • Its sixth line of text, a condition, is based on the fact that a Duelist in the anime who uses this card once in a Duel will not be able to use it again, as either they will win the Duel and trap their opponent's soul in the card, or they will lose the Duel and their soul along with it (barring DRAWs).[2]
  • This is the only card to have received a printed mock-up.
