Showdown in the Shadows: Part 2 - S2-E48
Continuity mistake: When Bakura is about to summon the Winged Dragon of Ra, in the shot of him saying "as I sacrifice my three monsters to summon this card," there are four monster cards on his duel disk. One fade edit later, the four cards on his duel disk have disappeared. While he said he was going to sacrifice three monsters to summon the Winged Dragon of Ra, he was never shown removing them. They just disappear. (00:03:50)
