This is what a more competetive version of Kaiba's deck might have looked like in Season 1, Ep. 1. Again I only used cards that had been release by 2004. Back when Yugi and Kaiba dueled for the first time, I would assume that the banlist would be the same one used for the Yugi-Kaiba Format, so I will go based on that banlist. (I.E. limited Monster Reborn, Pot of Greed, Change of Heart, Dark Hole and Raigeki.) The main reason I am going based on that banlist and not GOAT Format is because in Duelist Kingdom, Bakura used Change of Heart and so it had not been banned yet.
The inspiration for this deck came from Card Master Brian. The video is linked below.
