i forgot the promo, but i remember last year we had that one promo where we had two different overalls and when the overall went up +1 for the final week, they changed the champion set to 8 set cards instead of 5. i could see that happening with this promo or the next one since we are only doing like 1 or 1.5 weeks of 86s with 86 legends coming next saturday.
i wouldn't invest to heavily in 83s right now, but a few under 65k is a pretty safe play. the preseason totw cards would probably take 83s, but idk about a normal champion set
