Yu-Gi-Oh, but I Am a Card Elf

[Transformation] [Yu-Gi-Oh!] [Time Travel] [No System] [Sometimes there are less duels] [Single] [Elf (omnipotent)] What should I do if I die suddenly after staying up late reading a novel? Urgent, waiting online! As a high school student, Lan died suddenly while reading a novel in his dormitory one day. His soul was reincarnated into the world of Yu-Gi-Oh and became a card elf. However, someone looked at his body "What the hell, author. It's okay to turn into an elf, but what's going on?!" Well, yes, someone... No, she is no longer a human being (laughing) (This book is updated as the occasion arises) (If you are not an invincible stream, anyone may fail, including the protagonist, so please proceed with caution)
