I view custom cards as more a thing to have in your own collection, rather than a burgeoning market around them as things to sell. More for personal enjoyment/collecting. Although a few cases I remember customs actually selling for decent amounts- someone once had a Snape and Hagrid HP artbox auto on eBay made just to look like the official card design (those two never were in HP artbox, so would be desirable autos to some completionists). Then again, you certainly don’t have the same confidence the auto is legit compared to an official HP artbox auto…

I would not be for putting license logos like WB on the back since they’re not licensed, and also would be against including them on tcdb. That should be reserved for officially released, licensed cards, not homemade custom jobs.
