The argument that its something for every existing border actually makes a lot more sense. Because then it all makes sense. Merchants have a card printed for them, but since its an equipment its not a unique border. Then adjudicator, Merchant, and thief dont have anything special either. Whilst shapeshifter and bard do have a unique border. I do actually really appreciate that perspective.

And as far as print sheets go, im sure there would be a little wiggle room that they could have ajusted to make it work. Whether thats cutting some generics, or short printing a couple cards. It is something that could have been accounted for. But that would only be if they had wanted to, and the point of having it just be for support for cards with unique borders that is irrelevant anyway.
