Continuity mistake: In the previous episode, when Yugi realised that Buster Blader was one of the cards in his hand, Dark Magician was also one of the cards shown in his hand. In this episode, the Dark Magician card is never seen again.
Continuity mistake: When Yugi's life points go down to 3100 after Slifer the Sky Dragon destroys Buster Blader, his Kuriboh card is face down on his duel disk, even though it was face up when he summoned it earlier. Seconds after this happens, his Kuriboh card is suddenly face up on his duel disk. (00:14:19)
Other mistake: Marik summons Slifer the Sky Dragon, which is featured on his side of the field for the entirety of the episode, but whenever his duel disk is shown, the Slifer the Sky Dragon card cannot be seen on it. Instead, there is just a spell card, which shouldn't be there, because spell cards are inserted into slots on the duel disk and are not placed in the monster card zone.
Continuity mistake: When Yugi summons Kuriboh in defence mode, Kuriboh appears on the duel field, levitating a few inches above the Kuriboh card. In the next shot, Kuriboh is levitating several feet above the Kuriboh card. (00:09:05)
Other mistake: When Marik activates the spell card Pot of Greed, in the shot of him inserting the card into the spell/trap card slot, another version of the card can be seen in the monster card zone on his duel disk, even though it shouldn't be there. (00:06:30)
