I ran into Yami Bakura wandering the Duel World (as Yami Bakura, too) and got pulled into a game so tough he broke the rating scale! He used a Monster World themed deck to bring out Dark Master Zorc!
And he used exact words and said the DECK isn’t the same, but his Destiny Board of Doom skill still activated. I suppose I should’ve known better than to trust him. XD
