I remember watching it in the early 2010s. From what I remember, the protagonist was very energetic and had spiky hair, probably red, and also a sword nail. He was welcomed by a family, as if he were an exchange student.
He used cards and I remember that in the movie he summoned a dragon with them or something like that. On the cards, there was no dueling system, he just took the card and summoned a monster.
As I recall, at the end of the film he ends up becoming king of the prom or whatever.
I also remember that there was a commercial on Cartoon Network in which he appeared wearing a suit and a crown.
