I play EA FC and they have sum called evolutions. U can use them to make any player you want boosted up. They cost coins a lot of the time but for example it takes a certain player and gives them +5 speed +2 shooting and whatever. I think that would be fun in madden bc lets say u wanted to fill a whole in ur TT or have a good card of a guy still doesn’t have a card for some reason (Drake Maye) you could put them in evolutions. It’s essentially power ups but only certain specific stats are boosted and it allow more unique cards to be made.
