A Duel with Dartz: Part 5 - S4-E37
Continuity mistake: When Dartz tells his Orichalcos Dexia to destroy Yugi's Obnoxious Keltic Guardian, in the shot shown in front of Dartz, he is pointing at Yugi's monster with one finger, while the rest of his fingers are pointed downwards. When the shot cuts, the rest of his fingers are more relaxed and are pointed in a forward direction. (00:08:25)
