Totw cards. Probably +1 ovr on the requirements of part 1 Standouts and add one or two more pieces of each ovr
I think it's a safe bet to assume the sets will require TOTW cards again. All promo sets have stayed pretty consistent so far with what they require to complete the set. (TOTW re-rolls require wildcards, Team Builders require base cards, The 50 Fresh require wildcards.)
I'm hoarding TOTW cards and high golds. Last time Standouts released the TOTW re-rolls became cant-miss profits.
