A Duel with Dartz: Part 2 - S4-E34
Continuity mistake: When Kaiba activates the spell card Reflect Energy, a mini satellite appears on the wall behind Dartz. The satellite appears directly underneath the carving on the wall of a person whose soul was stolen by Dartz. The shot cuts to Yugi and Kaiba, but when it cuts back, the satellite has changed position and is now positioned in between two individual carvings. (00:14:34)
A Duel with Dartz: Part 3 - S4-E35
Continuity mistake: When Kaiba says, "Now I can do what your Siamese donkey twins should've done last turn," to Dartz, he draws a card from his deck with his right hand. Kaiba then has his dragon attack the Joey knight, and the card in his right hand has disappeared. (00:09:14)
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. (00:06:24)

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)

Continuity mistake: When the main characters have arrived on the base in the ocean, in the wide shot where Tristan is asking, "Just so I'm clear on this, you're good guys, right?", he is standing upright. When the shot cuts, his legs are more outstretched and bent slightly. (00:06:38)
A Duel with Dartz: Part 2 - S4-E34

Grappling with a Guardian: Part 2 - S4-E31
Continuity mistake: When Yugi summons Watapon to the field, after placing the card on the duel disk, he moves his right hand away from the duel disk so that it is pointed to the left.

(00:16:42)
Grappling with a Guardian: Part 2 - S4-E31
Continuity mistake: When Yugi summons Dark Magician Girl to the field in defence mode, another version of the card appears beneath it. The corners of the card are hovering over lines of light on the floor, caused by the Seal of Orichalcos card. A few seconds later, when Yugi ends his turn, the card appears to have moved away from the lines of light, as they cannot be seen on the floor under the card. (00:16:53)

Grappling with a Guardian: Part 2 - S4-E31
Revealing mistake: After Yugi has activated the Magical Pigeon spell card, there is a shot of him asking Rafael if he is confused, before explaining what the spell card does. In this shot, the cards Yugi is holding in his hand are missing the illustrations. (00:17:54)
Grappling with a Guardian: Part 3 - S4-E32

Continuity mistake: Yugi activates Five Star Twilight to summon the five Kuriboh brothers to the field. When the monsters appear on the field, the Kuriboh card can be seen in the third monster card zone on his duel disk. Seconds later, after Yugi uses the effect of the Kuribohs to lower the attack points of Rafael's monster, the Kuriboh card cannot be seen on his duel disk and has been replaced with another copy of one of the other Kuriboh brother monster cards. (00:16:50 - 00:17:19)

Grappling with a Guardian: Part 2 - S4-E31
Continuity mistake: When Guardian Eatos destroys Big Shield Gardna, the other characters are happy that Dark Magician wasn't destroyed.

Continuity mistake: After Joey's soul is taken away, Yugi says, "Oh, no," and Tea and Tristan stop running. At this moment, Yugi's deck can be seen inside his duel disk. A few seconds later, when Yugi looks up at the dragon on the roof, the deck has disappeared from the duel disk. (00:18:47)
