I have the same issue. Before I spent 100,000 coins on this I checked the pack description and it stated that the evolution could be used on a max. 87 player with max. 93 pace. It clearly stated max. 10 base playstyles, and at no point prior to me spending the 100,000 coins did it mentioned there was a limit of 1 playstyle plus. I identified a player and bought the evolution from the store. Only when I went to the Rewards section it then gave me the full description and states that there is a limit of 1 playstyle plus. The player I identified has 2 playstyle plusess, so is ineligible. I was looking for a stat boost on this player.
This paid evolution is deception. I would not have spent the coins on this evolution if the description in the store was accurate. I only had one player identified, and the evolution is now rendered useless due to the inaccurate deception in the store.
Take this evolution back, take the cards I packed back, and crucially, please give me my 100,000 coins back. It's not in any way appropriate to mislead players by not providing a full description. The evolution is dreadful value for coins when you see the conditions attached to it and I wouldn't have looked at it had further had I known what it actually contained.
