Revealing mistake: After the Shadow Duelist has activated the effect of Terrorking Archfiend and the flame has landed on the ball labelled 2, just as he says, "Mirror Gate is shattered", the card shown on his duel disk is misshapen, where two corners of the card are curved, instead of being straight. (00:16:23)
Revealing mistake: After the Shadow Duelist summons Infernal Queen Archfiend, Jaden says, "An Archfiend monster?" and the shot cuts back to the Shadow Duelist saying with that card on the field, every monster with Archfiend in its name gain 1000 attack points. In this shot, take note of the cards he is holding in his hand. He only appears to be holding onto two of the cards, but every other card in his hand appears to be held perfectly fine despite him not holding onto them. (00:12:41)
Revealing mistake: When the duel begins, the Shadow Duelist goes first. He has five cards in his left hand and draws a sixth card from his deck. He then places the sixth card next to the fifth card, and then picks up the fifth card in his hand, but the sixth card remains in the same position, without its position being affected by the fifth card being picked up. (00:12:32)
Revealing mistake: When Jaden says he's started hearing voices again, it cuts to a close-up of a flashback showing Jaden holding the Winged Kuriboh card. The shot appears to be flipped as the LIGHT symbol on the card, as well as the illustration of the card is reversed, compared to every other time this card is shown. (00:03:20)
