Do the new strat cards that come with the 97 ovr Master sets expire after the promo ends?
Yes, i did the Joe Namath set only for the Super Suit Strategy Card and right there in the card says that boost will end when the program is over.
But doing the set, concretely Joe Namath set is a good option to acquire a lot of trainning, you can snipe the 94s cards for 75k or less, so a total of 300 K for the 4 cards, then sell the 97 for 275 -300 k and his power up for around 15 -20k, and each of the NCAT that you get, quicksells for 4750 trainning each one, so a total of 19000 trainning that costs you like 20-30k if you sell cheap, if you are patient and sell the 97 and power up expensive you can basically get the 19000 trainng practically free
The Namath set is the best for this, as of the 4 97s , he is the only one whose power up is being sold right now above 15k, the others power up are being sold like for 5k or less
