Grappling with a Guardian: Part 2 - S4-E31
Continuity mistake: When Yugi activates the New World Circle spell card, there is a shot of him with his right arm raised while holding the card. In this shot, the other cards that he is holding in his left hand are pointed upwards. In the next shot, when he inserts the card into the duel disk slot, the cards in his left hand are pointed downwards. (00:20:05)
