- The heads on the crystals look like Egyptian death masks.
- The card's Japanese name is a pun on the Japanese word shinkirou, meaning "mirage". Hence, "Umbral Horror Mirage Tokens".
- Three "Umbral Horror Mirage Tokens" appears in this card's artwork.
- The number of Tokens summoned and part of their name being "mirage" can represent Yuma's first encounter with "Vector" as they turn out to be illusions.
