Li You: Emmm, System, are you really not willing to give me a normal deck?
System: Dear Duelist, bring smiles with your deck!
Li You: … I'm going to sneak across the border!!!!
This is a story about a protagonist who uses a System to build decks with cards rolled from the entire card pool, then plays cards and makes friends. You've stumbled upon a Yu-Gi-Oh! fanfic!
My new book, Yu-Gi-Oh! Card Swap, is a sequel to this book's GX arc. I've split it into two stories, so feel free to check it out if you're interested.
One more thing: The first twenty-five chapters of Volume Two are somewhat toxic because of my immature ideas. They have a dark history of crossover characters from all over the place, so new readers, please brace yourselves. If you find it uncomfortable, skip them! Even if you do, it won't really affect the later plot!
