Well i spent way too much time tonight exchanging 83s for 85-86
You can buy 83s for ~5k and exchange 3 for an 85-86. Legends and a few others that don't go into the new diamond sets could lose you 5k but there are plenty of cards going for 25-30k and some whales going for a lot more. It's monotonous but there is profit to be made if you enjoy such things. It may work for other exchange sets too but I saw the Bengals had some 85-86s going for a ton so I focused on that
