Earlier this year Nintendo ran a special competition for Pokémon Art Academy on 3DS that gave participants the chance to have their own masterpieces transformed into an official Pokémon Trading Card.
The winners of the competition each received a 100-card pack of custom-designed Pokémon Trading Card Game cards displaying their very own artwork. One winner by the name of James Franzen has been nice enough to share a few photos of his own entry as a final product.
Unfortunately there is no mention about fan made entries being distributed in the Pokémon TCG.
Let us know in the comments if you would like to see more competitions like this, and be sure to take a look at the other winning entries on the official Pokémon website.
