Number 47: Nightmare Shark

Number 47: Nightmare Shark was originally released in the 2014 Mega-Tins as part of a strategic initiative to reprint powerful cards from the Zexal era of the Yu-Gi-Oh! Trading Card Game. As an Xyz monster, it represents the core mechanics introduced in the Yu-Gi-Oh! Zexal anime, where monsters are layered to summon creatures from an extra deck. The card's aesthetic, characterized by its aquatic, predatory design, aligns with the game's tradition of thematic monster archetypes that utilize specific types or attributes to control the flow of the duel.

The card was designed by the creative team at Konami to offer players a unique utility option for Rank 3 Xyz decks. Its primary function—allowing a monster to attack the opponent directly—made it a notable inclusion for players looking to bypass defensive board states. Upon its release in the 2014 Mega-Tins, it was received as a solid, functional inclusion for the format, particularly valued for its ability to close out games during the later stages of a match.
