Courtroom Chaos: Part 1 - S3-E7
Continuity mistake: When Johnson tells Joey that he is giving up 1000 of his own life points, there is a Mystical Elf monster card on his duel disk. The monster card is placed in the second slot on the duel disk. Later, just after Yugi and Tea run into the courtroom, in the shot of Johnson saying "I believe it's my move," the monster card has moved to the third slot on the duel disk. The monster card also appears to be facing the opposite direction. (00:15:46 - 00:17:24)
