Here is my short postcode boxes which funnily enough, I opened with pokemonsyndicate today!! Haha
I didn’t even see this thread until a few mins ago.
Very interesting you made a post, and I am glad you take the time to research this well. I respect your efforts, and it’s good you admire the hobby like many of us do here.
I personally don’t know any true indicators on the decks yet. I just love to collect, and enjoy the hobby as is.
These are two short decks I broke today for fun.
2nd print booklet came from the first deck, both are identical.
3rd print grey booklet came from the second deck
Both have written the short postcode inside the booklets.
Dam crappy centering!!
Ninetales has an orange blotch on the left… Shame.
Anyways, that’s my breaks. I think could be an odd chance that these short postcodes may have non rarities. So I agree with you in that aspect. But didn’t work for me, and hasn’t been proven yet elsewhere.
