A Duel with Dartz: Part 2 - S4-E34
Character mistake: When Kaiba summons Blade Knight, he says, "Since I only have one card left in my hand, Blade Knight gets another 400 attack points." However, Kaiba has no other cards in his hand. Blade Knight was the last card in his hand before he summoned it. (00:14:00)
A Duel with Dartz: Part 2 - S4-E34
Character mistake: When Kaiba activates the Ring of Destruction trap card, he says, "Your knights are only safe if your Mirror Knight Calling magic card is in play," to Dartz. However, the Mirror Knight Calling card was shaded blue when it was summoned, meaning it is a Ritual Monster and not a spell/magic card. (00:19:23)
