n addition to the player cards, you can also get cards to improve the attributes of your stars. FIFA 18 has 24 different cards but only one card can be active on a player at a time.
However, again, the collective value comes into play . Indeed, depending on the level of the player's individual collective, the level of improvement changes: if you use the card on a player whose collective level is 10, the card will apply all of its effects. Conversely, if the individual collective level is less than 10, the value of the card decreases, until it is totally useless on a player with a collective score less than or equal to 4.
