There was a new time-limited Diamond Dynasty pack released for MLB The Show 17 on Friday. It is the Bases Loaded pack. It comes with one guaranteed Silver player, double the chance of a Gold player and triple the chance of a Diamond player.
You can buy a limit of four packs, and they cost 4,000 Stubs per pack. I opened up a single pack and Nolan Arenado was the first card I pulled. Your luck probably won’t be that good, but hey, there’s hope.
