I was recently trying to make a Garchomp/Lucario deck using the new cards from Ultra Prism. I went to a Pre-Release of the set and when I input my code for the promo I got a Lucario. It said it was banned and I thought it would only be temporary. Today I tried to make the Garchomp/Lucario deck and I saw that the promotional Lucario I have was still banned, but the normal non-promo one wasn't. I double checked and all the attacks, effects, numbers, and costs seem to be the same.
Is this intentional and I am just missing something? Is this a bug that affects my gameplay? Is it just a visual bug and I can still use it?
