Card Appearances:Book of Secret Arts


 * Yugi Mutou equips this card to Dark Magician in his duel aganist Joey Wheeler in the Duelist Kingdom finals. Then Joey activates Time Wizard's special ability, only to have transformed Yugi's monster into Dark Sage. The explanation for it was that he was equipped with Book of Secret Arts, even though the TCG makes no reference of needing this card to summon Dark Sage.


 * In the Battle City finals, Yugi equips this card to Dark Magician Girl to make her strong enough to destroy Dark Bakura's Dark Necrofear.
