Fanfictions

I may consider making one about yugioh. I was thinking about writing tag duels between protagonists and their rivals, but I don't remember a lot about peoples' decks/too lazy to learn about them again/haven't watched nearly enough zexal to have a good idea of Yuma's decklist.

Then I thought about making a fic about this academy and the people in it.

If I did that, however, Raiden would get so mad that I will only have 1 monster opening hands for the rest of my life.

Thoughts?
