Elf Deck To Senjou Gurashi

Our hero is just a regular high school student obsessed with Magic Walker, a wildly popular card game. His favorite? The Elf Deck—a seemingly weak set of cards that can become unstoppable with the right strategy. One day, while heading out to buy a new elf card, he gets picked on by some classmates. Things spiral, and the next thing he knows, he wakes up in another world—trapped in the body of the very elf character he wanted to add to his deck. To make things even stranger, he discovers he can summon elf cards from his old world in this new one.
