Yu-Gi-Oh Live Action Movie: True Soul

I am making a script for a new Yu-Gi-Oh live action movie I am thinking about making. It is about a young teenager who loves to play Yu-Gi-Oh, but has never been good at it. But one day for his 15th birthday, he gets a new pack of cards from his parents. When he opens the pack, he finds nothing special, except for 1 card he has never seen before. With this card, he puts it in one of his random decks and duels with it in tournaments, on his way to try and become the greatest duelist in the world. Give feedback and advice for this script, and tell me somethings I could add or take out. I may even put your name in the script!

I could really use the help. Thanks!

I also have some cards that you can check out that I'm planning to put in, if you want to see them.

It sounds pretty decent. What's that "one card he's never seen before"? Is it an official card or no?

It is not an official card. The card is going to be from a set called "Arch Demon Legacy" and the card's name is "Arch Demon: Light"
