One Step Ahead: Part Two - S5-E11
Continuity mistake: Just after Kaiba activates the Shrink card, causing the Valkyrie Brunhilde monster's attack points to get halved, Zigfried points out that she'll hit Kaiba. When Kaiba realises this, his right hand and forearm are pointed forward. In the next shot from behind Kaiba, his right hand and forearm are pointed to the right. Then in the following shot after that, his right upper arm is raised and his right forearm is pointed downwards. (00:10:20)
