Well, if I get ambitious and can figure out an easy way to mass convert the card graphics then I may have a go at it.
What I wanted to do was just create blank cards, all one colour. (A little known fact: support cards are yellow, boosters are pale blue, characters are darker blue and so on - playtest cards that is.) The tools I had immediately to hand I could edit the existing German cards to make them monocoloured - but the transparent rounded corners got lost.
