Unwanted Guest: Part Two - S5-E2
Other mistake: When Yugi starts losing Life Points after Petit Dragon is destroyed, the Life Point count appears to be well over 4000 when his points start to go down, even though duelists begin duels with 4000 Life Points. (00:05:08)
Unwanted Guest: Part Two - S5-E2
Other mistake: When Slate Warrior is destroyed by Luster Dragon, the DuelTek's life points go down to 3400. However, the points begin counting down from over 4000. First, duelists only have 4000 life points at the start of a duel, and second, the DuelTek's life points were 3700 at the end of the previous turn due to Luster Dragon destroying Airknight Parshath. (00:07:36)
Child's Play - S5-E5
Other mistake: Rebecca activates Graceful Charity, which allows her to draw three cards and discard two. One of the cards she discards is Marie the Fallen One, which is shaded yellow, indicating that it is a Normal Monster and does not have an effect. Later, it's revealed Marie the Fallen One has an effect that allows Rebecca to gain 200 life points every turn, meaning it is an Effect Monster and should have been shaded orange. (00:05:25 - 00:07:35)
One Step Ahead: Part One - S5-E10
Other mistake: When Kaiba summons Pitch-Dark Dragon to the field, there is one other card in his hand. He then sets a card face-down, which would mean that he has no more cards in his hand. But at the start of his next turn, right before he draws a card from his deck, there is already one card in his hand, even though he would have had no more cards in his hand at the end of his previous turn. (00:14:45 - 00:15:57)
One Step Ahead: Part One - S5-E10
Other mistake: When Kaiba activates Pot of Greed, there is one card in his left hand. He then draws two more cards from his deck, but then there are only two cards that can be seen in his hand, even though there should be a total of three cards in his hand overall. (00:15:57)
One Step Ahead: Part Two - S5-E11
Other mistake: When Kaiba summons Chaos Emperor Dragon, in the shot of him placing the monster card on the duel disk, the only other card in his hand is the Emergency Provisions spell card. On the same turn, he sets a face-down card, which he could only have gotten from the cards in his hand. Then he activates Emergency Provisions, and two additional cards can be seen in his hand. This would mean that there would have been four cards in his hand overall, even though he only had one card earlier in the turn. (00:14:05 - 00:14:35)
The Dark One Cometh: Part 3 - S5-E33
Other mistake: Yugi uses Spirit Sword of Sealing to remove Silent Swordsman LV7 from the field. When the monster card is pinned against the wall, it is shown to have 4000 attack points. These are the attack points for Silent Swordsman LV6, whereas Silent Swordsman LV7 has 4500 attack points. (00:16:42)
The Final Duel: Part 2 - S5-E38
Other mistake: Yugi activates Mirage Spell, which allows him to gain life points equal to the amount that Slifer the Sky Dragon was going to take from Valkyrion the Magna Warrior. Yugi's life points are then shown going from 850 up to 3400. However, Yugi's life points before this were 1400, not 850. He even says it increases his life points by 2000. (00:10:08)
