Suggestion to add a feature for EVOs!

Dear EA FC Team,

I am writing to you with an idea for a feature to add to your game.

When I make player evolutions, i love to create special players that probably no one else has and that got me thinking, what if there was a way to show that my evolution player is Unique?

So that's why I am suggesting to add a tag or a Special card design for the player that makes an evolution of a player for the 1st time or, when the evolution is out of the store, if they have a 1 of 1 player  evolution that cant be made again.

Maybe this would be automatically checked by your system when a person finishes the evolution, or there would be a button to "Check rarity" or something like that.

For EA i think this could be a way to get people to buy more evolutions, so they can try to be the first to complete a new evolution or spend more to make a unique chain of evolutions. And i would even pay to get the design or tag on the player when i find that i made a unique evolution.

For the users this would be a way to show their achievements and to know that they have made a special card that noone else has.
This could also be tied to some achievements maybe, or challenges to create a unique player.

Feel free to discuss in comments further why this would or would'nt work.

Best wishes, 

Me
