Grappling with a Guardian: Part 2 - S4-E31
Continuity mistake: When Guardian Eatos destroys Big Shield Gardna, the other characters are happy that Dark Magician wasn't destroyed. Mokuba then points out, "That's true, but he gets to attack again," and raises his forearms while closing his hands into fists. When the shot cuts, his left forearm is suddenly lowered. (00:09:38)
