I think there will be a big TA collection to end the year (maybe like the LS collections...a card for each collected division, league, and then a monster for all the set 3 and set 4 TAs collected.
I see them going that road instead of making them part of this collection...but who knows.
I am good with either as the reward for collecting 120 TA cards is something good.
I just took Posey literally half an hour ago after also chosing Reggie. Should rake even more so in the next moonshot event. Platoon him at first / catcher in ranked with Biggio at C.
