Hey TCDBers
I some how missed this issue when it came out in 2015. The set, 2015 Platinum Series Baseball was a game, much like Topps Attax, Stat-o-Matic, and APBA. The cards look better though. It was a start up on Ingiegogo a couple years ago. Anyways I was looking around COMC and found some of the cards and had never heard of the set. I've added it to the 2015 Baseball set list, but the company has since shut down and so has their website. From what I can gather there were 600 player cards. You can see a review of the game, which was not good, here https://sportdice.wordpress.com/2015/08/06/review-platinum-series-baseball/
Anyways I was looking for the checklist and have been unable to find one. COMC has about half of the set listed on the site, but if anyone knows were to find the checklist or can add it go for it.
