A Duel with Dartz: Part 3 - S4-E35
Revealing mistake: When Rafael confronts Dartz after arriving at the castle, in the shot of him saying "Don't answer that, I've heard enough lies from you, the Pharaoh opened me up to the truth," Yugi can be seen in the background of the shot, but his Millennium Puzzle is missing the designs that are usually shown on the front.

A Duel with Dartz: Part 3 - S4-E35
Revealing mistake: When the Yugi knight protects the Joey knight from Kaiba's attack, Tea says, "This time Yugi protected Joey." When Tea says this, her little finger is bent at an incredibly unnatural angle. (00:09:38)
A Duel with Dartz: Part 3 - S4-E35
Revealing mistake: After the Joey knight has blocked Kaiba's attack on the Mai knight, Kaiba says, "Figures Wheeler mess things up," and then inserts a card into one of the slots on his duel disk. The slots on the duel disks have always been shown to be aligned with monster card zones on the front of the duel disk, but when Kaiba sets the card, he inserts it in an area in between where the monster card zones are located, meaning he inserted the card in between the slots, rather than in one of the slots.
