Card Trivia:Cursed Seal of the Forbidden Spell
- This is an enhanced counterpart of "Magic Jammer", with similar artwork and a more specific cost.
- The Forbidden part of this card's English name is a nod to how its effect "forbids" the Spell Card it negates from being used for the rest of the Duel.
- Coincidentally, the English version of Invasion of Chaos (the Booster Pack that this card made its TCG debut in) was released in March of 2004, the same year that the Advanced Format (and thus the Forbidden list) was introduced.
