In episode 131, Kaiba uses this card during his Duel against Yami Yugi. He summons this card and "Blade Knight" via "Thirst for Compensation". The effect of "Slifer the Sky Dragon" then immediately activates, but Kaiba activates "Card Guard" to discard a card and prevent his monsters' destruction for one turn. He then Tributes both this card and "Sword of Soul" to activate "Obelisk the Tormentor"'s effect, destroying all monsters on Yugi's side of the field and inflicting 4000 damage to Yugi ("Slifer" was not destroyed by the effect because of its own effect, but the effect damage was still going to be inflicted to Yugi's Life Points), but Yugi discards "Kuriboh" to negate the damage he would have received. Later "Slifer" (whose ATK was 6000 due to its own effect) attacks "Obelisk", but Kaiba activates "Power Balance" to discard half of the cards in Yugi's hand and draw the same number of cards Yugi discarded. Yugi then activates "Necromancy" to Special Summon this card, "X-Head Cannon", "Kaiser Sea Horse", and "Blade Knight" from the Graveyard. This activates the effect of "Slifer the Sky Dragon", destroying the newly summoned monsters. This activates the second effect of "Necromancy", decreasing "Obelisk the Tormentor's" ATK to 1600 until the End Phase ("Obelisk" lost 600 ATK for each "Necromancy"-summoned monster that was destroyed). "Obelisk" then gained 1000 ATK due to this card's effect, but Yugi activates the effect of "Electromagnetic Turtle" to end the Battle Phase immediately.
