The Forbidden Ritual: Part 1 - S3-E40

The Forbidden Ritual: Part 1 - S3-E40
Continuity mistake: When Zane picks up Echo's necklace, in the shot of him picking up the necklace, his thumb is placed at the bottom of the pendant. But in the next shot, his thumb is over the top of the pendant. (00:06:32)
The Forbidden Ritual: Part 1 - S3-E40
Character mistake: Aster uses his Diamond Dude's ability to activate Destiny Draw from his graveyard, allowing him draws two cards from his deck. After doing this he then refers to Destiny Hero Diamond Dude as Destiny Dude instead of Diamond Dude. (00:14:30)

The Forbidden Ritual: Part 1 - S3-E40
Other mistake: When Aster summons Destiny Hero Dunker, in the shot of him showing the card to Adrian, its attack points are 1100, as shown on the card. The monster then appears on the field, and its attack points are 1200, as shown by the attack point display. (00:14:52)
The Forbidden Ritual: Part 1 - S3-E40
Revealing mistake: Aster activates the ability of Destiny Hero Dunker, allowing him to send one Destiny Hero monster to his graveyard so that Adrian loses 500 life points. In the shot of the monster being placed into the slot where cards are sent to the graveyard, the bottom of the card is partially laid over the circular light on his duel disk beneath the slot. Despite this, the card remains completely straight and doesn't bend when placed over the light. (00:14:57)
The Forbidden Ritual: Part 1 - S3-E40
Character mistake: When Aster attempts to attack Adrian with his Destiny Hero Dread Master, Adrian activates a face-down card Dimensional Prison, to which Aster replies "Great, a Counter Trap", however, this card is actually a Normal Trap card. (00:17:05)

The Forbidden Ritual: Part 2 - S3-E41
Continuity mistake: When Aster runs in front of the main characters to protect them from Exodia, Jaden asks what he is doing, to which Aster replies "Saving my friends."

(00:18:40)

Conquering the Past: Part 1 - S3-E42
Continuity mistake: When the main characters are walking through the wind in the opening scene, Crowler asks Jaden where they are going, to which Ojama Yellow replies to find Jesse. At this moment, Crowler has his right thumb pressed against his middle finger. But in a closer shot of Crowler, his thumb is pressed against his index finger. (00:00:12)
Conquering the Past: Part 1 - S3-E42
Character mistake: Just after Zane destroys Jaden's Spark Blaster, he says "You were too afraid to fuse your Sparkman with your Spark Blaster last turn", however he used the wrong wording. "Fuse" means to combine two monster cards into one Fusion monster. He meant to say "equip" as equip spell cards like Spark Blaster are equipped to monster cards like Sparkman. (00:06:52)
Conquering the Past: Part 1 - S3-E42
Character mistake: When Zane destroys Jaden's Hero Barrier card with the effect of his Armoured Cybern, he says "Why wouldn't you play that spell?", but Hero Barrier is a trap card. (00:07:08)
Conquering the Past: Part 1 - S3-E42
Character mistake: When Zane destroys one of Jaden's face-down cards, which is then revealed to be E - Emergency Call, he says "That was the trap, Emergency Call." However, E - Emergency Call is a spell card, not a trap card. (00:07:33)

Conquering the Past: Part 2 - S3-E43
Continuity mistake: At the start of the episode, in the shot where Jaden's life point count appears on screen, there are four cards in his hand. A couple seconds later, there are five cards in his hand. (00:02:17)
Conquering the Past: Part 3 - S3-E44
Other mistake: By removing Cyber Valley and Cybernetic Hidden Technology from the game, Zane can draw two cards. The two cards are two individual Overload Fusion cards. He activates one Overload Fusion card, and at the end of his turn, he places the other card face-down. When Jesse attempts to attack, he reveals the face-down, which is revealed to be Dimension Explosion. (00:08:52 - 00:11:54)

The Ultimate Face-Off: Part 1 - S3-E45
Continuity mistake: When everyone is standing around Zane's duel disk at the start of the episode, there is a shot showing the duel disk on the ground, that pans upward toward Syrus. In this shot, Zane's deck cannot be seen in the duel disk. Later, after Bastion picks up Zane's duel disk, in a shot of him saying to Syrus "our friends are still out there", Bastion briefly lifts the duel disk into frame, and the deck can suddenly be seen inside it. (00:02:24 - 00:03:55)

The Ultimate Face-Off: Part 2 - S3-E46
Continuity mistake: When the purple bridge appears in front of the main characters, Ojama Yellow jumps on it. He is shown toward the middle of the bridge at first, but in the next shot, he is suddenly toward the edge of the bridge. (00:08:30)

The Power Within: Part 1 - S3-E47

The Power Within: Part 1 - S3-E47
Continuity mistake: When Jaden has a vision of his duel monsters, in the group shot, Burstinatrix is a few meters ahead of Avian. But in the next shot, Burstinatrix and Avian are side-by-side. (00:04:19)
The Power Within: Part 2 - S3-E48
Plot hole: Jaden activates Super Polymerization to fuse Elemental Hero Neos and Rainbow Dark Dragon to summon Rainbow Neos. Where exactly did Rainbow Neos come from? All the cards used in the Yu-Gi-Oh universe come from companies that developed them and the Rainbow Dragon card was only first made earlier in the season, so there's no way a monster that requires Rainbow Dragon as a Fusion material monster would exist. (00:17:43 - 00:18:43)

Return of the Supreme King: Part 3 - S3-E51
Other mistake: When Jaden summons Elemental Hero Clayman in defence mode, the shot pulls out slightly and Jaden says "And now I activate Rainbow Neos' second ability." At this moment, Clayman can be seen on Jaden's duel disk, and the card is placed vertically on the disk, indicating that it is in attack mode. (00:06:55)

Return of the Supreme King: Part 3 - S3-E51
Revealing mistake: After Yubel's life points go down to 400, she tells Jaden should he win, they will protect him. The shot after Jaden says "Protect me?", it cuts back to Yubel saying she has always tried to shelter him from harm. In this shot, the purple mark on her face cannot be seen and it is then suddenly animated onto her face midway through the shot. (00:11:37)
