The Heart of the Cards - S1-E1
Revealing mistake: When Kaiba shows Solomon the briefcase full of cards, there is one card with 1600 attack points and 1800 defence points. The defence points of the card appear to be a lot lighter than the card's attack points, as well as the attack and defence points of the other cards. (00:04:52)
The Heart of the Cards - S1-E1
Revealing mistake: When Yugi and Joey are duelling at the start, in the shot of Tristan approaching Joey, the cards that Yugi is holding appear to be drawn incorrectly. The cards don't have the text or illustrations that are usually shown on them. (00:01:46)
