Card Tips:Cursed Seal of the Forbidden Spell
- This card can be searched by "A Cat of Ill Omen", "Guiding Ariadne", and "Sacred Arch-Airknight Parshath".
- You can use this to negate your own spell cards, but only your opponent will be unable to activate other cards with the same name as that negated card.
- This card is very useful against Twin Twisters because once the first copy is negated, the other two become useless.
- Not many Decks that focus on a single Spell Card will have a backup plan once their main strategy is crippled, so run multiple copies of this card to pull this off faster.

- Any Fusion-based Deck - "Polymerization"
- Blackwing - "Black Whirlwind"
- Dark World -"Dark World Dealings" and "The Gates of Dark World".
