A Duel with Dartz: Part 6 - S4-E38
Revealing mistake: When Roland has told Kaiba that there is a hurricane heading for the East Coast, the shot cuts to Kaiba asking "Hurricane?", which shows all the main characters in the shot. In this shot, many characters' eyes are misdrawn. Notably, their eyes are too small, but also, Mokuba's pupils are shown in the corners of his eyes. (00:11:29)
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.
Joey Wheeler, Shadi: Go, Drumsticks.
Mai Valentine: Uh, guys? Joey named his chicken.
Joey Wheeler, Shadi: It's a Nematory, Mai.
Mai Valentine: Whatever.
