For those keeping score at home. Here is the current list of physical Steem Monsters promo's produced so far.
Don't stress yourself trying to collect all of these, that feat will be darn near impossible.
Hundreds of code promo cards have been created in 2020-2022 most of those ive stopped listing.
I'm glad I took the time to document all the early cards, the backs of the cards will likely tell a story.
If you have a card not on the list, hit me up on Discord so I can help you identify it.
