I've just read the first two chapters and I really like the concept but just as a preference of mine have you ever thought of writing card names in Bold idk just a peeve of mine.

I’m not sure if you’re aware, but when I tried it, the link to the forum didn’t really work. Had to jump through several hoops to get there, so you might want to try putting the app in your bio, for convenience’s sake(I’ll still probably submit an OC, because I really can’t stop making them).

Anyways, the story itself is a mixed bag for me. On the one hand, there are some character interactions which I really enjoyed, Yuto and Ms. Yuniko being prime examples. They are generally quite expressive, and I appreciate that.

On the other hand, the dueling action can be a bit hard to follow due to the way you format it(most of the important plays occur back-to-back, in bulky paragraphs). Also, some of the dialogue isn’t quite as clear as it could be. For example, "Yeah, my brother made me that deck and that's why I'm here in the city." This gives the impression that Yuto is in the city because his brother made him a deck, which is...odd.

There were a few grammar mistakes here and there, but I’m not going to nitpick in that regard. Overall, I’d suggest finding someone you trust to be a beta reader/editor for the fic. I think you’ve certainly got some things right, but the story has room to be polished.
