Those cards look a lot like yugioh cards in terms of the template. Hopefully you made them yourself 'cause otherwise it probably won't pass well with the judges.

Greetings Timespiraled,
These cards are totally homemade based on "Magics Card" style and each color-typed card are just the same template with different color shades.
To be honest, I didn't even know how Yu-Gi Oh! cards looked like so I browsed the web to find it out and yeah, I do understand why both of you guys thought these were Yu-Gi Oh! cards... but rest assured that it's really 100% homemade with Photoshop. :)
