The Final Face Off: Part 5 - S3-E45
Other mistake: When Kaiba and Mokuba have begun the detonation sequence, a timer on the console begins counting down. The countdown is supposed to be one hour, as Kaiba told them the island will explode in that time, but the timer appears to count down incredibly quickly, with minutes passing by in seconds. (00:16:42)
The Final Face Off: Part 2 - S3-E42
Other mistake: When Marik has the Monster Reborn card after taking it from Yugi's graveyard, there is a close-up of the card in his hand. In the close-up, the spell card Fiend's Sanctuary can be seen among the cards in his hand. However, Marik does not have this card in his deck. Yugi has this card in his deck as Kaiba gave it to him at the start of the duel. (00:05:50)
Clash in the Coliseum: Part 6 - S3-E37
Other mistake: When Kaiba says "This is where it all ends, Yugi," a Blue Eyes White Dragon monster card can be seen on his duel disk. At this point, the only monster on his field is Blue Eyes Ultimate Dragon, so Blue Eyes White Dragon shouldn't be on his duel disk. The same mistake happens again when Kaiba says "No, I need my Ultimate Dragon to win the duel," right after Yugi activates De-Fusion, before the three White Dragons reappear on the field. (00:14:48 - 00:18:11)
Clash in the Coliseum: Part 5 - S3-E36
Other mistake: Kaiba activates The Flute of Summoning Dragon, which allows him to summon any Dragon-type monster from his hand. At this point, he has four cards in his hand. He then holds up two Blue-Eyes White Dragon monster cards in his right hand, but there also appear to be four cards in his left hand, even though there should now be two instead of four. (00:08:55 - 00:09:16)
Clash in the Coliseum: Part 4 - S3-E35
Other mistake: Kaiba activates the spell card Card of Demise, which allows him to draw cards from his deck until there are five cards in his hand (as long as he discards his entire hand after five turns). Once he has five cards in his hand, he summons the monster card Lord of Dragons from his hand, which should bring the total number of cards in his hand down to four, but instead he has three cards in his hand, instead of four. (00:17:03 - 00:17:43)
Clash in the Coliseum: Part 4 - S3-E35
Other mistake: When Kaiba sets the trap card Cloning face down on the field, he has five cards in his hand. On Kaiba's next turn, he still only has five cards in his hand, even though duelists are supposed to draw one card from their decks at the start of their turn. (00:10:20 - 00:11:29)
Noah's Final Threat: Part 1 - S3-E20
Other mistake: When Yugi draws the Cyber Jar card from his deck, the front side of the card can be seen briefly. In this brief moment, it is a spell card and not a monster card. It becomes a monster card when he goes to set it a few seconds later. (00:07:25)
Settling the Score: Part 2 - S3-E12
Other mistake: When Leichter is boasting about how he has three times as many life points as Kaiba, just as Kaiba says "Just try," the Lord of Dragons monster card can be seen on his duel disk in defence mode. However, Lord of Dragons isn't a monster that Kaiba has on his duel field; it is just the monster he selected as his Deck Master. (00:03:15)
Settling the Score: Part 1 - S3-E11
Other mistake: When Kaiba's bodyguard walks into Kaiba's bedroom, the door appears to have a lock on the interior side of the door, but no lock on the exterior side of the door. (00:13:20)
Settling the Score: Part 1 - S3-E11
Other mistake: When younger, Kaiba has duelling cards laid out on the floor; one of the Exodia monster cards can be seen. The Exodia cards have always been presented as extremely rare monster cards, and it is unlikely Kaiba would have one of these. (00:12:40)
