in the card printing files for the battle deck pages 13 and 14 (the final 2 card’s fronts and backs) don’t line up (they have to be aligned when you flip one of the sides over) so you have to use one of the other pages (even pages 2, 4, 6, 8, 10, or 12) of card backs for page 13 fronts.
Also, the word “Upgraded” on the battle cards are not consistent in font size for some reason. Main text on battle cards is too small and there is plenty of room to make it bigger to make it easier to read.
