"A Duel with Destiny, Part 2", known as "One Strike That Changes the Future" in the Japanese version, is the ninety-fourth episode of the Yu-Gi-Oh! anime. It first aired in Japan on February 12, 2002 and in the United States on October 18, 2003.
Although Kaiba fights well against Ishizu, she still is unfazed by him thanks to her Millennium Item. When Ishizu has him cornered and nearly out decked, it seems that her vision will come true and that Kaiba will be defeated. Suddenly Kaiba receives a vision of his own from the Millennium Rod that might save him from Ishizu.
In this Duel's final turn, the timing of activation for Kaiba's "Soul Exchange" is unclear to determine: is it at the end of Ishizu's turn or during his own turn? It is however very likely that "Soul Exchange" is played as a Quick-Play Spell Card (As per one of the Battle City rules) at the end of Ishizu's turn, otherwise Ishizu would have been free to attack Kaiba directly with her 3 monsters and win the duel, and also due to the fact that Kaiba Normal Summoned "Blue-Eyes White Dragon".
Even after Kaiba used "Soul Exchange" to summon "Obelisk the Tormentor", it's seen again when Kaiba is considering using the "Blue-Eyes White Dragon" instead.
Similarly, due to the particular way in which "Sacrifice's Blast" (a.k.a. "Blast Held by a Tribute") works in the anime, it is shown to activate immediately after Kaiba takes control of Ishizu's monsters. In a subsequent scene displaying the Arena (after Kaiba summons his "Blue-Eyes White Dragon") both Duelists are shown to have no cards face-down on the field. This confirms that Ishizu's card has already been "activated", unbeknownst to Kaiba. This also significantly bends the real-game rules, since "Sacrifice's Blast" would have to remain on the field until it is activated (presumably, at the moment "Obelisk the Tormentor" attacks). This requirement is however skipped for dramatic effect.
In the dub, when Mokuba is translating the text, a Lifepoint noise is heard before he heads out to check on Kaiba's duel.
Featured Duel: Seto Kaiba vs. Ishizu Ishtar, Part 2
Tuen 13: Kaiba
Kaiba draws "Virus Cannon" and subsequently activates it, but Ishizu activates her face-down "Muko" to negate the effect of "Virus Cannon" and destroy it.
Turn 14: Ishizu
Ishizu draws "Zolga" and subsequently Normal Summons it (1700/1200) in Attack Position. "Zolga" attacks and destroys "Dark Gremlin" (Kaiba 2950 → 2850). "Kelbek" then attacks directly (Kaiba 2850 → 1350). Ishizu Sets a card.
Turn 15: Kaiba
Kaiba's hand contains "The Flute of Summoning Dragon", "Silent Doom", "Blue-Eyes White Dragon", "Soul Exchange", "Ring of Destruction", and "Obelisk the Tormentor". Kaiba draws "Crush Card"[Notes 1], but Ishizu activates her face-down "Muko" to send the drawn card to the Graveyard. Kaiba Sets a card ("Soul Exchange"). Kaiba intends to activate his set card once Ishizu gets three monsters out onto her field.
Turn 16: Ishizu
Ishizu draws. She then Sets a card ("Sacrifice's Blast"). In the anime, Ishizu reveals (to the viewers, thinking to herself) that this Trap has already begun infusing its power into one of Ishizu's monsters ("Zolga"), so that when Kaiba uses "Soul Exchange" to seize its control and tribute it, it will be transferred to the Tribute Summoned monster i.e. Kaiba's "Obelisk the Tormentor". Once Seto attacks directly with "Obelisk", the effect of "Sacrifice's Blast" will activate, defeating Kaiba. Ishizu Normal Summons "Agido" (1500/1300) in Attack Position. Kaiba activates his face-down "Soul Exchange" to allow himself to Tribute his opponents' monsters as if he was their controller. Kaiba then Tributes "Zolga", "Kelbek", and "Agido" in order to Tribute Summon "Obelisk the Tormentor" (4000/4000) in Attack Position.
Turn 17: Kaiba
Kaiba draws "Polymerization". He prepares to use "Obelisk the Tormentor" to attack directly, but Yami Marik's Millennium Rod activates and gives Kaiba a vision of the past. He sees himself as an ancient priest carrying a woman while standing in front of a stone tablet showing the "Blue-Eyes White Dragon". This convinces him to change his strategy.
Kaiba then activates "Silent Doom" to revive "Gadget Soldier" (1800/2000) in Defense Position. He then Tributes "Gadget Soldier" and "Obelisk the Tormentor" in order to Tribute Summon "Blue-Eyes White Dragon" (3000/2500) in Attack Position (thus negating the "Sacrifice's Blast" secretly infused in "Obelisk"). "Blue-Eyes White Dragon" attacks directly (Ishizu 1400 → 0).
Differences In Adaptations
The 5 pointed star on "Muko" is given more points in the dub.
As before, "Virus Cannon" is changed from a Magic to a Trap Card in the dub.
