I’ve done it 4 times and haven’t gotten anything over 82. Same with the 82+ There may as well not be a + on it for mine.That guaranteed 81-87 player SBC which is repeatable is great mind. Costs fuck all to do, and is piss easy to do with players you've probably already got. 5 common gold's, then just any old bronze players is all that's needed.
Done it 5 times so far and packed 87 Sczezny, 84 Martial, 85 Havertz, 82 Ramsey, and 81 Mendy (Man City one).
I'll likely do it loads more tomorrow with shite from my club.
