Number 10: Illumiknight

Number 10: Illumiknight was introduced in the 2011 Yu-Gi-Oh! Trading Card Game booster set Photon Shockwave. As part of the Xyz Monster category, which had been recently introduced in the Yu-Gi-Oh! Zexal era, the card reflects the aesthetic shift toward metallic, futuristic designs that defined the series' early Xyz releases. The card's design features a knightly figure clad in glowing armor, intended to evoke a sense of celestial power that fit the set's thematic focus on light-attribute monsters.

The card was illustrated by artists working for Konami's R&D division, following the established visual language of the Numbers archetype from the anime. While the card was initially received with curiosity due to its specific ability to manipulate hand resources, it ultimately saw limited competitive play compared to more versatile Xyz monsters of the same rank. Its Ultimate Rare printing remains a point of interest for collectors who favor the textured, embossed foil finish that characterizes this particular rarity within the Photon Shockwave release.
