Hi, the deck image should be the most expensive Legendary card image if I am right, but I have found that my yellow deck with “Khalim, Sky Prodigy” shows the image of “Last Nightmare”. I tried to update the deck building order without success. I don’t know if there is a way to select what image to use to represent any deck anyway
I think it’s just the most expensive card of any category.
I’ve got Primeval Colossus on a few of mine.
Would be nice if you could pick, though.
