- "Dark Sage" could be Special Summoned by Tributing "Dark Magician" if either player succeeded in the effect of "Time Wizard". Its effect also allowed its controller to activate Spell Cards during the opponent's turn.
- In episode 34, Yugi Muto uses this card during his Duel against Joey Wheeler. After Joey succeeds in the effect of "Time Wizard", "Dark Magician" and "Baby Dragon" are transformed into this card and "Thousand Dragon" respectively. "Thousand Dragon" then attacks this card, but Yugi uses this card's effect to activate "Makiu, the Magical Mist" which negates the attack made by "Thousand Dragon". On Yugi's next turn, he used this card's effect to add "Monster Reborn" from his Deck to his hand. This card remained on the field until the Duel was over.
