Now, This is only an idea mind you, but it seems as though they are wanting to follow a specific card type for each stage of TA. I think that we can all assume stage 4 is set aside for the finest series cards, I wont discuss that much.
So stage 3 is bound to have a specific card series, and I think something along the lines of "Hometown Hero" would be fitting. The criteria would include someone that accomplished amazing feats for their specific team, or someone that wore the jersey for the entirety of their career and had success. Something similar to these.
Ill throw out some of my guesses as to what cards I could see this being, but I would love to hear everyone else's thoughts as well. I know SDS Does not currently have a version of some of these cards in the game, but you never know which new legends could be introduced!! LOL
I also tried to exclude anyone who may already have a high diamond card. I am also not a huge expert of each and every baseball team so please forgive me if I forgot someone from your team and offended you.
