NFTs != images. Art NFTs are one implementation of NFTs (and not one I’m a fan of). A token representing a Magic card doesn’t need any association with the art on that card, it just needs to exist so anyone can verify that I purchased that card (and therefore the ability to use its mechanics) from WoTC. A 3rd party game that allows me to play Magic can verify the NFT card ownership and can use it’s own art or no art at all, just like they do today. The only difference is that today’s 3rd party Magic sites don’t have verified ownership of cards so everyone uses the most expensive cards.
