Isolated in Cyber Space: Part 2 - S3-E3
Revealing mistake: When younger, Kaiba and Mokuba are playing chess. There is a shot of them resetting the pieces on the chessboard to their original position so that they can play again. In the shot, the chess pieces are incredibly tiny and do not resemble real ones. (00:06:43)
Duel Identity, Part II - S1-E30
Character mistake: Yugi mistakenly says if he doesn't get a monster out to defend himself Mai can attack him directly, which wouldn't be possible since the rules of Duel Monsters during the Duelist Kingdom arc forbade direct attacks on defenseless opponents. That rule wouldn't be implemented until the Battle City arc.
Seto Kaiba: I'm surrounded by superstitious nitwits.
