Elevate players from the rookies promo can't be added to the evolution lineupIf you start now, you can get Ayton 108.
If you grind hard you can get him with boost.
I'm assuming that a lot of those un-opened items are elevate tokens.
If that's the case, you can easily get some elevate players from the rookies promo and level them up to 107.
This will also push up your elevate team.
Good luck.
