Thanks for the reply.
I haven't figured out how to attach the pictures of my cards so here's a link to where I've posted for sharing (https://ibb.co/5LyzrdP - let me know if it doesn't work). Sorry, I'm sure it's not ideal as a scan would be - and the angle sucks but I tried to minimize glare. I can scan them if it'd help. One thing I'll note - the backs are much more similar to the base card and do not necessarily mirror the differences on the front.
That being said, and while I very much appreciate your insight (re: MSA not releasing), I'm not sure what that means. By "backdoored" are you suggesting someone may have snuck them out from the production facility? Thanks!
