Continuity mistake: When Jaden summons Bubbleman to the field, he uses the card's special ability to draw two more cards from his deck.

Amnael's Endgame: Part 1 - S1-E45
Other mistake: When Jaden places Elemental Hero Burstinatrix on his duel disk, the Elemental Hero Bubbleman card can be seen next to it.

Continuity mistake: At the start of the duel, in the shot where Amnael says "Is that so? But what if you do not possess what it takes Jaden", there are five cards in his hand.

A couple seconds later, after activating Chaos Distil, whilst he is explaining the card's effect, the card positioned second to his right is now placed over the card to the right of it. (00:09:13 - 00:09:38)

The Seventh Shadow Rider - S1-E44
Continuity mistake: When Jaden, Syrus and Chumley walk into the cafeteria, they leave the door open when they go to sit down. But later in the scene, after realising that Chazz at their food, just before Syrus stands up to say "Professor", the door is closed. (00:00:08 - 00:00:36)
The Seventh Shadow Rider - S1-E44
Continuity mistake: There are three trays shown on the cafeteria table closest to the door when Jaden, Syrus and Chumley walk in. When the three shout for Professor Banner later in the scene, the trays have disappeared from the table. (00:00:08 - 00:00:36)
Revealing mistake: When Pierre says "You're only extending your fate, my Cherie, and not even by that long", the shot cuts to Alexis, shown from the side of her face. In the background, Crowler and Sheppard can be seen sitting in the seating area, but their bodies don't appear to be aligned with the seats and are shown passing onto the seat next to them. (00:14:02)
Duel Distractions: Part 1 - S1-E36
Continuity mistake: A woman walks into the classroom holding an abandoned bag. When Banner asks "May I help you", the woman's hands are positioned outside of the straps, but when the shot cuts, her hands are inside of the straps. Also, during the shot, she has her right hand off the bag, but when it cuts to a close-up of the bag, her right hand is suddenly holding onto it. (00:04:35)
Duel Distractions: Part 2 - S1-E37
Continuity mistake: When Tania shows Jaden the Amazoness Arena card, the two fingers she has pressed against the front of it are positioned at an upright angle. It then cuts to a close-up shot of the card, where the two fingers are at a rotated angle. (00:08:12)
Duel Distractions: Part 1 - S1-E36
Continuity mistake: When Syrus tells Chumley about his card crush, Chumley raises a card that he has a crush on to Syrus. He is shown holding the card with two fingers at a straight angle. When the shot cuts to a close-up of the card, Chumley's fingers are at a bent angle. (00:02:54)
Field of Screams: Part 2 - S1-E32
Continuity mistake: When Chazz is looking over his cards in his room, his hands are folded, and the cards are on the bed. Ojama Yellow then appears and Chazz doesn't move his hands, but when the shot cuts, he is suddenly holding some cards in his hand that is suddenly raised. (00:04:30)
Continuity mistake: When Chazz is ranting in his room, in the shot where Ojama Yellow comes out of his deck, the deck of cards shown on his bed is positioned at a rotated angle. A couple seconds later, when he says "If you want to see pressure" to Ojama Yellow, the deck of cards is now no longer positioned at an angle. Then, later in the scene after Syrus tells Chazz his door is way over there, the deck of cards is further down the bed. (00:00:12 - 00:00:43)
Continuity mistake: When everyone is walking in the hallway, Chazz takes out his Ojama Yellow card. He is holding it with two fingers, but when it cuts to a close-up of the card, Chazz's fingers cannot be seen holding it. (00:06:10)
Continuity mistake: When Chazz's brothers are speaking with him in the locker room, in the shot where one brother says "Now it's your turn, bro", there is a yellow bag and blue bag shown in the background. The yellow bag has one strap sticking upwards, and one strap bent to the side, but two shots later, both straps on the yellow bag are sticking upwards. (00:05:13)
Other mistake: When Jaden has Elemental Hero Wildheart attack Chazz directly, Chazz's life points go down to 2100. Chazz's life point count remains this way for a large chunk of the duel, but when Elemental Hero Flame Wingman destroys Armed Dragon LV7, Chazz's life point count is 2800. Technically speaking, Chazz does lose the correct number of life points since his go down to 1600 and there was a 500-point difference between the two monsters, but his life points shouldn't have been listed as 2800. (00:05:44 - 00:15:15)
Continuity mistake: After Crowler has thrown the chickens into the other vault, there are chicken feathers spread out on the floor beneath him. Two shots later, the feathers are suddenly closer together. (00:00:57)
