Which cards from the Zeo community and staff did you enjoy the most, and why
TAHK0 speculated on why the error may have happened, writing, Poke Balls went through a lot of early variations, with everything from the button placement changing, to how it opens differing, to even being depicted with the white on top. It could be that an early Pok Ball design actually did open like it does on the card back, but when the design was eventually changed to the opposite way, they forgot to update it on the card back before going to print, and it remains that way to this day
