Tough Love - S2-E43
Other mistake: When Zane and Aster are talking outside the Duel Academy building, in the shot of Aster saying "I'm just impressed that I beat you on live TV", Zane's deck can be seen inside the duel disk he is wearing. The top card doesn't appear to have the black-coloured oval shape that is usually shown on the cards. (00:02:40)
Tough Love - S2-E43
Character mistake: When Zane activates the trap card Power Wall, he explains that for every card he sends to the graveyard, Syrus loses 100 points. What he meant to say, was that for every card he sends to the graveyard, the amount of life points he loses during the attack is reduced by 100 points. Since neither Zane nor Syrus lost life points during this, what he said was obviously incorrect. (00:14:47)
Tough Love - S2-E43
Character mistake: When Zane is explaining Cyberdark Dragon's ability to Syrus, he says that for every card in his graveyard, his dragon gains 100 points, before saying "Since there are 38 dragons in my graveyard, Cyberdark Dragon gains 3800 points." However, his deck consists of monster cards, spell cards and trap cards, his statement that there are 38 dragons in his graveyard is incorrect. (00:18:00)
Continuity mistake: When Hassleberry and the two Slifer Red students are sitting outside the classroom, there are two piles of books around them. A couple seconds later, when Hassleberry and one of the Slifer Red students stand up after Crowler appears, the books are now in three piles. (00:06:11)
Other mistake: When Dr Collector activates Graceful Charity for the second time, he has it in his right hand. He then appears to lower the card off-screen, but then he goes to draw three cards from his deck with his right hand. He never placed Graceful Charity on his duel disk or sent it to his graveyard. It's just never seen in his hand again. (00:12:24)
Other mistake: When Aster summons Destiny Heroes Diamond Dude and Captain Tenacious to the field, they are summoned in defence mode, but on the points display, the word ATK is shown, indicating that it is in attack mode. (00:14:42)
The Phoenix Has Landed: Part 1 - S2-E48
Continuity mistake: When Aster takes the Destiny Hero Plasma card to show Sartorius, he has two fingers pressed against the front of it. In the close-up shot, there is one only finger pressed against it. (00:06:19)
The Phoenix Has Landed: Part 1 - S2-E48
Continuity mistake: When Aster activates D Fortune, he has his left hand positioned at his side. Then there is a close-up of his duel disk, and his left hand is over the front of his body. (00:18:22)
The Hands of Justice: Part 1 - S2-E50
Continuity mistake: After the opening titles have played, there is a shot from above where explosions are around the forest and then the shot pans over to Duel Academy. In this shot, no-one can be seen outside the building. In the next shot, students have suddenly appeared in front of the building. (00:02:45)
The Hands of Justice: Part 1 - S2-E50
Revealing mistake: Right before Chancellor Shepherd briefs the students about the tournament, there is a shot of Obelisk Blue and Ra Yellow students around the outside of the building. Later in the episode, after Zane gives his medal to Blair, the scene cuts to outside Duel Academy, and the exact same shot of the Obelisk Blue and Ra Yellow students has been repeated a second time. (00:02:48 - 00:08:45)
The Hands of Justice: Part 2 - S2-E51
Continuity mistake: When Blair summons Mystic Egg, in the close-up of the monster appearing, it's a few feet away from the line on the ground. A couple seconds later, when Blair says, "Bon appetite", the monster is directly on the line. (00:03:50)
Other mistake: When Jaden summons Elemental Hero Neos using his Silent Doom card, Neos is in defence mode when it appears on the field, but on the point display that appears when a monster is summoned, the word ATK is listed, meaning that it is in attack mode, when it should say DEF (defence mode). (00:10:20)
Revealing mistake: When the main characters are in the other dimension, they are shown walking on sand quite a lot, but they never make any footprints when walking across it.
Continuity mistake: When Jaden is sitting on the Duel Academy ledge, just after Syrus and Hassleberry are first shown standing on the ground, Hassleberry comments that imaginary companions are a natural part of cognitive development. At this moment, he has his elbow against the large stone behind him. When the shot cuts, the position of his arm on the stone has changed. (00:05:08)
Plot hole: When Blair walks into Chazz's dorm, Hassleberry says "It's Blair" as if he knows her. However, Hassleberry has never met Blair and shouldn't know who she is. (00:19:15)
Jewel of a Duel: Part 1 - S3-E2
Continuity mistake: After Jaden destroys Crystal Beats Emerald Turtle and Cobalt Eagle, the two monsters reappear as crystals on the field. When the blue crystal appears, a shadow can be seen beneath it. When the shot cuts, the shadow is a lot smaller. (00:19:48)
Jewel of a Duel: Part 2 - S3-E3
Continuity mistake: When Aster is telling everyone that Jesse was chosen by his monsters, just as Blair says "Give me a break", a Ra Yellow student can be seen sitting next to Chazz. A couple seconds later, when Aster says "You don't believe me", the student sitting next to Chazz has disappeared. (00:10:03)
Hanging with Axel: Part 2 - S3-E5
Other mistake: Jaden activates the spell card Contact Out to remove Elemental Hero Flare Neos from the field and summon Elemental Hero Neos and Neo-Spacian Flare Scarab from his deck. When he spreads out his cards to find the two monsters, a Fusion monster can be seen. However, Fusion monsters are never included in the main deck as they are only summoned when two monsters are fused together. (00:08:12)
Hanging with Axel: Part 2 - S3-E5
Continuity mistake: After Professor Viper says, "What is he thinking?", it cuts back to Axel drawing a card from his deck. When he looks at the card he just drew, his right hand is higher than his left hand. In a close-up shot of the cards, his right and left hand are level. (00:12:09)
Head in the Clouds: Part 1 - S3-E7
Deliberate mistake: Adrian walks outside the Obelisk Blue dorm to see Chazz standing on a glass platform held up by four cables on each corner, which are attached to a helicopter flying above. Adrian then realises he is standing on a glass platform, held by cables and attached to a helicopter. There is no way he wouldn't have noticed this; he should've seen the cables, heard the helicopter and felt the glass platform beneath him when he walked onto it, even if it makes for a cool reveal.
