Elf Deck to Senjougurashi

Our unnamed protagonist is an ordinary high school boy who loves Magic Walker - a super-popular card game. In particular, he loves the Elf Deck: a selection of cards that, while seemingly weak, can be incredibly powerful when played right. One day, while on his way to get a new elf card, he gets bullied by his peers. One thing leads to another, and soon he wakes up in another world... in the body of the elf character he was hoping to get his hands on. And wouldn’t you know it, he can summon elf cards from his old world too. From the duo who created Mazumeshi Elf to Yuboku gurashi, and the author of Dungeon Nursery.
