Breaking of the Sacred Seal - S3-E23
Continuity mistake: After Adrian realises Marcel was holding four of the five Exodia cards in his hand, Adrian comments "If you had drawn one more card, you would have completed Exodia" while holding onto Marcel's arm.

Character mistake: When Marcel activates his two face-down cards, he says "I'll start by revealing my two face-down cards which both happen to be Break the Seal spell cards", but they are trap cards as they are pink and spell cards are green. (00:15:10)
Breaking of the Sacred Seal - S3-E23
Continuity mistake: When Echo is warning Pegasus not to move closer, in an overview shot, there are two aides on his left. One is a few meters next to him, and the other is a few more meters ahead of the first aid. Just under a minute later, when Pegasus says "Okay, I was kind of with you until that last bit", both aides to the left of Pegasus are side-by-side. (00:10:55 - 00:11:50)
