Card Trivia:Sealed Gate
- This is one of many Spell/Trap Cards that cannot be activated, and can only use their effect when destroyed. The others are "Blackwing - Boobytrap", "Dark Coffin", "Hero Medal", "Kozaky's Self-Destruct Button", "Spell Calling", "Statue of the Wicked", "Wonder Garage", and "Z-ONE", the anime-exclusive "Dormant Volcano", "Dowsing Point", and "Zombie Bed", and the manga-exclusive "Cross Counter Trap".
- "Limiter Overload", "Ojamagic", and "Waking the Dragon" function similarly, but can also activate when sent to the Graveyard by other means.
