 * Normal Summons "Orichalcos Gigas" (400 → 900 ATK / 1500 DEF) in Defense Position.

Dartz places it in the Spell & Trap Card Zone, meaning it can't be attacked until Dartz's first-row monsters are destroyed first.

Seto Kaiba's Turn

 * Activates Spell Card "Polymerization", fusing his "Blue-Eyes White Dragon" on the field with 2 more "Blue-Eyes White Dragons" from his Hand to form "Blue-Eyes Ultimate Dragon" (4500 ATK / 3800 DEF) in Attack Position.

 * Activates Spell Card "Polymerization", fusing his "Black Luster Soldier" with Seto's "Blue-Eyes Ultimate Dragon" to form "Master of Dragon Soldier" (5000 ATK / 5000 DEF) on Yami's side of the field (NOTE: in the real game, "Master of Dragon Soldier" is called "Dragon Master Knight").
 * Activates Trap Card "Meteorain": all of Yami's monsters obtain the Piercing effect (when monsters attack with an ATK that is higher than the DEF of the opponent's Defense Position monster, the difference is inflicted as Battle Damage to the opponent's Life Points).
 * Uses "Master of Dragon Soldier" to attack & destroy Dartz's "Orichalcos Gigas" but thanks to "Orichalcos Kyutora's" effect, Dartz receives no Battle Damage 652010_42023_PM.jpg" as it prepares to attack]]

Differences in adaptations

 * Cut from the English version is a sequence in which the helicopter flies on, while the gang watch out the rear, wondering where the helicopters are leading them, then seeing a dark cloud approaching them, but then realize it is a swarm of locusts, and then the locusts surronding the city.
 * Shots of the gang walking towards the temple of removed from the dub.
 * A shor of Kaiba thinking that if Yami is a really skilled duelist, he should have the card to finish Dartz
