Story: It has such a great story, and I loved almost every minute of it. Of course it has alot of flaws, but even with those flaws I still find the overall story enjoyable. The flaws are mainly with the characters which I'll talk about in character tab. As far as the dueling mechanic for in real life dueling. For it's time it was almost accurate to a T. It just forgot the aspect that alot of people usually beat their opponent by turn 2-3.
In the show my favorite thing had to be the 10 second skip button as I do enjoy duels sometimes, but most of the duels is just taking 10 seconds to summon this and that, and this has this ability, etc. Etc. Like I get it. That's what yugioh is, but I was more interested in the overall story. So I did skip some duels at times. And that let me speed through the entire series. I did watch the important duels because I'm like alright how does Yuya beat this person?
(Spoilers) First Arc was about Yuya and friends just introducing them, and what they can do.
Second Arc Hey there's a championship going on, but it's also where you learn the biggest secret that their are 3 other dimensions compared to your own. And yours is the Standard dimension while the others are Fusion, Synchro, and Xyz. The fusion dimension is trying to take over the other dimensions other the guise that they're trying to unite the dimensions into one.
3rd arc going to the synchro dimension to find allies to fight the fusion dimension. But learn that they have their own problems of Rich vs. poor people, and they despise each other
4th arc resolving that issue
5th arc accidentally going to the xyz dimension, but resolving their problems anyway. As the Fusion dimension took over the Xyz, and now you're trying to show them a different way of life.
6th arc. The second main villain reveal the main protag was the main villain all along, and main girl is a reincarnation that beat you long ago and also the second main villain's daughter. And he was just trying to revive his daughter, but in doing so did not realize that he was accidentally reviving the main villain. And now the main protag's main villain reemerge and everyone do their best to beat the main protag back into his regular self until main girl's descendant beats him back into his usual self. And now the main protag had to prove that he can control the keys to make sure main villain doesn't reemerge again, while also finding away to revive main girl. Though lets just say everything ends the way you wanted it to, and it's a happy ending to finish this long explanation.
Art: Simply put, it's great. I like the style of alot of the characters.
Sound: I like alot of the openings and endings.
Characters: You watch Yuya grow as a character, and he really carried the show. I mean he is the main protag after all. Though at times he gives in to a dark side, but learns better to control it
Yuzu-Beginning of the series she had great character development until she became a mary-sue mid way and all she ever said was Yuya in different ways. She honestly would've been a possible favorite if not for that.
As for the other characters they were all fine, and each have their individual quirks and things you could love about them.
Overall: Even with all the flaws I enjoy this series alot, and would probably show it to kids who want to enter into anime. I love the different aspect and emotional swings in the show, but the overall message was to make everyone smile and enjoy the show or duel. Because the it's made for everyone to have fun
