Suggested by Sonic Yuya and Jack are both talented duelists with a whole lot of cards at their disposal. In terms of pure talent I’d say that you have to give this to Jack. He was one of the world champion level duelists for a long time because of how good he was and he can always hold his own in a fight. That said, Yuya was the main character of his own series which helps him out a whole lot because of all the cards he has. He got almost all of the summoning techniques by the end of the series and all together I would say his army is just more powerful than Jack’s. The Red Dragon Archfiends are definitely formidable but this time they just won’t be enough. Yuya wins.
