A Duel with Dartz: Part 3 - S4-E35
Continuity mistake: When Yugi switches Big Shield Gardna back into defence mode, his left hand is pointed to the right, and his right hand is placed on the duel disk. In the next shot, his left hand is suddenly raised towards him so that he can look at the cards in his hand, and his right hand is also raised so that he can pick one of the cards. (00:13:10)
