Other mistake: When Zane activates Trap Jammer, the monster Elemental Hero Bubbleman can be seen on his duel disk, even though Cyber Dragon is the only monster on his field and Zane does not have Bubbleman in his deck. (00:09:57)
Other mistake: When Zane has Cyber End Dragon attack Elemental Hero Shining Phoenix Enforcer, Aster activates a trap card that allows him to send 5 monsters to the graveyard. One of these monsters is Elemental Hero Clayman, but it's shaded orange, and since Clayman is not an effect monster, it should be shaded yellow. (00:18:55)
A New Breed of Hero: Part 1 - S2-E6
Other mistake: When Jaden has Elemental Hero Flame Wingman attack Aster's Elemental Hero Clayman, the Clayman card appears to be orange. However, monster cards are only orange when they have a special ability, and since Clayman doesn't have an ability, it should be yellow. (00:10:54)
A New Breed of Hero: Part 1 - S2-E6
Other mistake: After Jaden activates Miracle Fusion, he removes Elemental Heroes Flame Wingman and Sparkman from his graveyard (and removes them from play) so that he can summon Shining Flare Wingman. In the shot of the cards coming out of the duel disk, Sparkman is shaded orange. But since Sparkman is not an effect monster, it should be shaded yellow. (00:14:50)
A New Breed of Hero: Part 2 - S2-E7
Other mistake: Aster uses the effect of Magical Stone Excavation to send two cards to the graveyard to bring back one spell card. Polymerization is coming out of his graveyard, but a second later, it is now Misfortune that returned from the graveyard. (00:14:10)
Other mistake: When Syrus visits Jaden in the hospital wing, Chazz hands him Jaden's deck, telling him he can't see his cards. Decks are usually said to have 40 cards, but when Syrus spreads the deck of cards apart, there only appear to be about seven cards in his hand, and nowhere near the full deck of cards that was just handed to him. (00:00:29)
Other mistake: When Syrus looks at Jaden's cards, in the close-up shot, Elemental Hero Sparkman is shaded orange. Since Sparkman does not have any effects, it should be shaded yellow, not orange. (00:00:32)
Other mistake: When the images in Jaden's cards begin to reappear, one of the cards in his hand is Fusion Sage. Later, when he uses Neo-Spacian Aqua Dolphin's effect, he is discarding Fusion Sage from his hand to the graveyard. That same turn, he uses Aqua Dolphin's effect again, and to do so, he discards another card from his hand. However, Fusion Sage is getting discarded even though it was already discarded earlier that turn and he didn't have any other Fusion Sage cards in his hand. (00:16:48 - 00:17:22)
Other mistake: After Hassleberry activates Survival Instinct and removes from play two dinosaur monsters, the attack points of Curry Fiend Roo go up by 600. However, on the point display that is shown when the points go up, the word DEF can be seen, indicating that it is in defence mode. Since it is the attack points of this card that are going up, and it is currently in attack mode, the word ATK should have been shown in the point display instead. (00:16:18)
Other mistake: Just after Syrus has summoned Ambulance Rescueroid to the field, he uses the effect of Cyber Summon Blaster to inflict 300 points of damage to Hassleberry. At this point, Hassleberry should have 2900 life points (which then go down to 2600). But for a split-second, his life point count reads 4000, which then shifts to 2900 when his life points go down. (00:12:55)
Other mistake: After Cyber End Dragon has been summoned and its attack points have doubled, the next shot of Zane shows Chimeratech Overdragon on his duel disk, instead of Cyber End Dragon. (00:16:10)
Homecoming Duel: Part 2 - S2-E16
Other mistake: Jaden tells Aster that Elemental Hero Flare Neos gains 400 attack points for every spell and trap card on the field, and since there are 4 spells and traps out, then Flare Neos gains 1600 attack points. The attack points of Flare Neos then go from 2500 up to 4200. This is 1700 points, not 1600. (00:15:40)
Other mistake: When Chazz summons Armed Dragon LV3 in attack mode, the Life Point display is shown to display the monster's attack points, rather than the Attack Point display that is usually shown. (00:06:55)
Other mistake: When Jaden destroys Slifer 30, Bob tells him he has to drink a full bowl of water in 60 seconds. Once he finishes the bowl, water is shown dripping from his head and splashing up from the bowl, meaning that the bowl couldn't have been empty. (00:14:14)
Other mistake: When Jaden yanks Aster's steak into the air after mistaking it for a fish, Aster snatches the steak back with his fork. However, the steak had already been pulled into the air, so it would have been impossible for him to reach it. (00:02:56)
Other mistake: Jaden throws his fishing hook at the ocean, and it lands on Aster's steak. When Jaden goes to pull it back to him thinking it's a fish, Aster snaps the hook from the fishing rod, leaving the hook attached to the steak. Aster then continues eating the steak, but the hook cannot be seen inside it, even though it was never removed from the steak. (00:02:57)
Other mistake: Franz gives up 1000 life points to destroy all monsters on Jaden's field, going from 2200 to 1200. Later, Franz activates Winged Dragon of Ra's secret ability, allowing him to sacrifice all but 1 life point to add it to Ra. However, when this happens, his life point count starts at 4000, when it was 1200 earlier. Ra gains 1199 attack points, so it does gain the correct number of points, but it was still wrong for the life point count to read 4000. (00:12:45 - 00:14:30)
Pro-Dueling - S2-E38
Other mistake: When Crowler and Bonaparte approach Damon and Mathmatica during their duel, Mathmatica appears to have 4000 life points. A couple minutes later, when Mathmatica loses 1000 life points due to Damon correctly guessing which card he would draw, Mathmatica's life points are now 3000 (which then go down to 2000). (00:04:33 - 00:06:53)
Pro-Dueling - S2-E38
Other mistake: When Damon summons Doron to Mathmatica's side of the field due to Mathmatica activating Illegal Summon, the monster is summoned in defence mode, but the display reads ATK, indicating that it is in attack mode. (00:05:18)
Pro-Dueling - S2-E38
Other mistake: When the MaƮtre D increases the attack points of his Bacchus monster, the Life Point display is shown to display the attack point count going from 1600 to 1900, and not the Attack Point display that is usually shown. (00:11:09)
