Stealing others' fanarts and putting them into items without asking and removing signatures of original creators isn't nice at all, even when that person sell them without even crediting the art creator, THAT IS WORSE.

But I'm thinking of another reason why he stole those arts. Maybe the card maker accidentaly stole them. He didn't noticed that some of arts appeared on his card are fan-made, probably just popped out instantly when he was searching for arts at internet.

However, it could be true that he stole it deliberately. We never know which one is true unless the card maker tells the truth of it.
