Card Trivia:World Legacy's Nightmare
- "Mekk-Knight Avram", "World Legacy - "World Lance"", "Beckoned by the World Chalice", "World Chalice Guardragon", "Knightmare Goblin", "Gryphon", "Unicorn", "Phoenix", and "Cerberus" appear in this card's artwork.
- This depicts the scene right after Ningirsu instantly defeats "Knightmare Mermaid" in one go, drawing the attention of the rest of the Knightmares and allowing Avram to continue pursuing Iblee in the distance.
- This is the first "World Legacy" Field Spell Card that does not increase the ATK/DEF of the monsters of the archetype it supports.
