Fighting with Cards, But Isn't It Just Playing a Card Game?!

Just before transmigrating, Baishi spoke with a god. The god said it would grant him special powers and told him to get ready.

God: "You'll gain the power to fight with cards, and your most common move will be using two cards together."

Baishi: "Got it. So this is a card game! Fusion, Synchro, Xyz... I wonder which one it'll be?"

God: "You'll gain some of an alchemist's knowledge, as well as the ability to pursue the study of alchemy."

Baishi: "Got it. This is set in Yu-Gi-Oh! GX! Guess I'll have to become a lackey of the Fusion Dimension. I wonder if I can pull out monsters banned by the Forbidden List and beat the primitive people senseless?"

God: "Now, go to another world and complete the task I've set for you."

Baishi: "Duel Academy, huh? I wonder what kind of role I'll have. Just an ordinary student, or maybe someone with a connection to Professor Daitokuji?"

The white light faded. Looking at the GotcharDriver in his hand and the Yu-Gi-Oh! cards in its case, Baishi fell silent. He looked up and saw the Sky Wall stretching across the land. He was in Touto, from Kamen Rider Build.

Wait a second, isn't this a bit too much of a mash-up?
