Card Appearances:Numeron Spell Revision
- In episode 138, Don Thousand uses this card during his Duel against Mizar (not revealed until later on when Don Thousand Duels Yuma Tsukumo and Nash). When Mizar activates "Dragon King's Demise" to Tribute "Schwarzschild Limit Dragon", "Parsec, the Interstellar Dragon", and "Galaxy Stealth Dragon" and inflict their combined ATK as damage to both players, Don Thousand activates the second effect of "Numeron Network" to activate this card from his Deck, negating the effect of Mizar's "Dragon King's Demise" and activating "Card of the Dragon King" instead. Due to "Card of the Dragon King", Mizar is forced to Tribute his Dragon-type monsters, inflict their combined ATK as damage to himself, and draw one card for each Dragon-type monster Tributed, winning Don Thousand the Duel.
- This card also appears in a flashback Don Thousand has when he explains how he used "Numeron Network" and "Numeron Spell Revision" to defeat Mizar.
- In episode 139, Don Thousand uses this card during his Duel against Yuma and Nash. When Nash activates "Aqua Jet" to increase the ATK of "Boom Shark" by 1000 (Nash planned to use "Boom Shark" to attack directly and then activates its first effect to inflict damage to Don Thousand equal to its ATK on the field), Don Thousand activates the second effect of "Numeron Network" to activate this card from his Deck, negating the effect of "Aqua Jet" and activating "Surface" instead. Through "Surface", Nash revives "Cutter Shark" and the second effect of "Boom Shark" destroys itself. However Nash wanted this to happen since "Numeron Network" could not use its second effect more than once in a turn.
