I Play Yu-Gi-Oh! at Hogwarts

Louis transmigrated into the world of Harry Potter, where he gained the ability to create duel cards.

"Hey, Professor Snape, let's duel."

"I don't have time to play childish games with you!"

"You don't get to decide that. The duel has already begun... I activate my trap card, Call of the Haunted, and summon the ghost of a dead person to fight for me."

"Damn you, you evil dark wizard! How dare you desecrate the soul of the dead?!"

"My target is Lily Potter."

"Heh heh, Professor Snape, give up. If you don't, I might summon James Potter's spirit next."

"Don't you dare!!!"
