The Final Duel: Part 4 - S5-E40
Continuity mistake: After the Pharaoh tells Yugi that he can draw one card from his deck due to the effect of his Dark Illusion, Yugi then draws one card from his deck and places two cards face down. When he does this, his duel disk is pointed downwards. But in the next shot, the duel disk is upright. (00:08:30)
