Nice!
Though if they were double sided, there is no way we can see all these cards in the same shot. If it starts at odd numbers (i.e. #1), #3 and #4 would share the same card front and back, if it starts even (i.e. a cover graphic and #1 on the same card), #4 and #5 should share the same card front and back.
Right, didn’t think of that :)
