Another random idea that popped into my mind recently while I was catching up on yu-gi-oh's.

What if someone from our world gets sent to the yu-gi-oh universe? The specific timeline is still undecided but if all goes well then it should be ether. Vrains or Arc-v if not then it should be GX.

So basically someone from our world gets sent to the yu-gi-oh universe with card collection. Naturally all his cards from our dimension gets turns into real cards.

Also if you didn't get the hint he has God cards like Slifer, Ra, Crimson Dragon, Exodia, even Holactie and other rare crap.

Naturally he won't be running around and flashing his ultra rare cards to every random person. My main character won't be that dumb! No, he'll be using a more "normal" decks for his daily use.

Tell me what you guys think?
