Got the 96 Davante LTD Ghosts card for around 630k the day it was released for my most expensive buy in MUT 22 so far.
With a 96 PUP in hand, I sold him last Friday for 1.1 million, and bought his Free Agency card for just over one third of my takings. Result: way more coins than I started the day with, and a fully powered up gold 99 Adams.
Great business, all in all.
