This card can be seen as a physical counterpart and partner to "Dark Magician". "Buster Blader" has a support card, "Skilled White Magician", which works exactly the same as the support card of "Dark Magician", "Skilled Dark Magician". In addition, "Miracle Restoring" can work for either this card or "Dark Magician". Both also wear somewhat similar armor, and are the Fusion Materials for "Dark Paladin".
In the Anniversary pack artwork of this card, a faint shadow of a dragon's jaws can be seen in the bottom right of the picture.
