Card Trivia:Shaddoll Zefranaga

- This card's Japanese name, "Ye Shaddoll - Sephiranaga" (イェシャドール－セフィラナーガ Yeshadōru - Sefiranāga), is a reference to the name "Yeshua", which means "salvation" in Hebrew.
- Fittingly, "Kerykeion" ascended after defeating "Sophia, Goddess of Rebirth" (as depicted in the artwork of "Sacred Serpent's Wake"), which is similar to Jesus Christ.
- Also, the Book of Revelations tells of Jesus' Second Coming, which is similar to how "Kerykeion" returned during the war with the "Infernoid" monsters.

- This card is named after the nāga, a deity or class of entity or being, taking the form of a very great snake.
