Continuity mistake: When Jaden summons Elemental Hero Clayman to the field in defence mode, another version of the card appears beneath Clayman for him to kneel on. The card is shaded yellow, but around a minute later, the Clayman card is suddenly shaded orange. (00:10:14 - 00:11:09)
Continuity mistake: Crowler opens his trench coat to Chazz and his friends to reveal the rare cards. The cards are displayed in the boat as three separate rows, all equally distanced from one another. A couple seconds later, in the shot of Crowler saying "What's the matter, Chazz? Don't recognise me", the top row of cards is suddenly further away from the other two rows. (00:08:10)
Continuity mistake: When Crowler reveals the rare cards in his jacket, on the top row, there is a spell card with an orange hammer on the illustration (This card is called Hammer Shot). There are then a series of close-ups of the card, and when the Hammer Shot card is shown in the close-up, it is suddenly on one of the middle rows. (00:08:10)
Plot hole: When the collection of rare cards is shown inside Crowler's jacket, the Fusion monster Ojama King can be seen as one of the rare cards. However, Chazz doesn't acquire the Ojama cards until later in the season, and he is unaware of their existence until he gets them. Also, the Ojama cards are depicted as relatively useless, unless used in the right way, so it is extremely doubtful that an Ojama card would be seen in a collection of cards that are depicted as rare and valuable. (00:08:11)
Revealing mistake: When Jaden says "I got a whole army of vicious army of monsters in my deck just waiting to get at you", a small animation glitch occurs in the bottom right corner of the frame. Just as he begins saying "waiting", he moves his left arm slightly, and part of the red colouring on his blazer disappears from shot, almost as if the animators forgot to colour it in. (00:15:27)
Continuity mistake: After Jaden's life points have gone down to 1000, in the shot of Chazz saying, "Having some test anxiety", his arms are pointed down toward the ground. When the shot cuts to focus on Jaden, his arms are suddenly raised. (00:15:20)
Revealing mistake: When Chazz summons X-Head Cannon and Z-Metal Tank to the field, he is shown standing completely still, without any body movement in sight. He was in the middle of summoning monsters, so he shouldn't have been standing still like that. (00:13:02)
Continuity mistake: The duel starts with Jaden having five cards in his left hand, and then drawing one card from his deck with his right hand. The card is revealed to be Winged Kuriboh. Jaden never moves any of the cards in his hands around, but then he summons Elemental Hero Clayman, which he is shown holding in his right hand, even though Winged Kuriboh was just shown in his right hand. (00:09:58)
Revealing mistake: Right before Jaden and Chazz start the duel, in the shot of Crowler saying "Indeed, and in front of the whole school too", there are two Slifer Red students who appear to be standing completely still and motionless. (00:09:43)
Continuity mistake: When Jaden is telling Syrus he still lives at the dorm, in the shot of him saying Ra Yellow is nice, there is a still shown at the edge of the bed. Later in the scene, when Jaden is trying to stop Syrus crying on him, the stool is suddenly further from the bed. (00:19:48 - 00:20:21)
Continuity mistake: When Jaden walks into the dorm at the end of the episode, in the shot from above, he leaves his shoes on. A couple of seconds later, when the same shot angle is shown again, his shoes are suddenly off, even though he was never shown taking them off. (00:19:37)
Revealing mistake: When Syrus and Bastion walk onto the arena field to congratulate Jaden, there are extras animated in the background who are cheering yet appear frozen and not moving in any way. (00:18:24)
Continuity mistake: In the flashback of the card shop owner giving Jaden the pack of rare cards, in the shot focusing on her, she is holding the pack with two hands, but when the shot focuses on Jaden, she is holding the pack with one hand. (00:15:45)
Continuity mistake: At the start of the duel, Jaden draws a card from his deck, which is placed in between two fingers. When the card is revealed to be Winged Kuriboh, it is now placed in between his thumb and one finger. (00:09:57)
