In the first above-mentioned episode, this card appears in a flashback Ishizu has when she notes to herself what happened when Kaiba used this card to tribute her monsters and summon "Obelisk the Tormentor".
In the second above-mentioned episode, this card appears in Ishizu's thoughts when she notes that once Kaiba attacks, the effect of "Blast Held by a Tribute" will destroy "Obelisk" and inflict its ATK as damage to Kaiba.
In episode 129, Kaiba uses this card during his Duel against Yami Yugi. He adds this card from his Deck to his hand via "Spell Sanctuary". Later Kaiba uses this card to let him Tribute Yugi's "Queen's Knight" and "Alpha the Magnet Warrior" for a Tribute Summon. Kaiba intended to Tribute them and his "X-Head Cannon" in order to Tribute Summon "Obelisk the Tormentor" but Yugi activates "Change of Heart" to take control of "X-Head Cannon" until the End Phase. Kaiba then activates "Enemy Controller" to pay 1000 Life Points and take control of "X-Head Cannon". Yugi then activates "Lightforce Sword" to remove the "Obelisk the Tormentor" in Kaiba's hand from play for three turns. On Kaiba's End Phase, this card's effect expired, returning Yugi's monsters to his side of the field.
