Revealing mistake: At the start of the duel, in the shot of Alexis saying "If you give me the key now...", the Society of Light dorm members can be seen sitting in the seating area in the background. On the front row, there appears to be two students merged into one seat. (00:11:50)
Character mistake: After Alexis has White Knight Queen attack Sparkman and then has Snow Fairy attack Card Trooper, Jaden tells her that Sparkman's ability activates, which allows him to draw one card. This is not correct; it is actually Card Trooper that has the ability to let him draw one card, not Sparkman. (00:06:44)
Character mistake: When Jaden has his Elemental Hero Neos and Neo-Spacian Flare Scarab fuse together, he says "Roll call, Flame Scarab, Neos, contact fusion." When he says this, he incorrectly refers to Flare Scarab as Flame Scarab. (00:17:20)
Tough Love - S2-E43
Continuity mistake: When Jaden opens the top button on Syrus' blazer, five GX medals fall onto the ground. Three of the GX medals land face up, but two shots later, when Jaden goes to pick them up, all the medals are face down. (00:00:47)
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).
