Free as in you get that card guaranteed for doing nothing like Griffin and Westbrook you got a 70 of them for no effort at all you just had to train it up after that the Halloween cards can be free but you're not guaranteed that specific card from the pack and also they are part of a promo meaning they won't make anymore after the promo ends but Westbrook and Griffin were an exclusive program that will have an update in the next few weeks with new playersIf I have the Halloween version of Blake Griffin in my lineup, the "Update Team" button is activated, even though the Halloween version of Blake Griffin has better detailed stats. But the "Update Team" button is greyed out if I have the Elevate version in my lineup.
By free cards, do you mean the Elevate card or Halloween? as I think they were both free. The Elevate version is the only one I can level up and it's at 83.
I still can't understand why the Elevate version shows better stats on the main attribute screen, but worse detailed stats.
