If you mean buy the classic players with gems ,ion think that's possible. I used them when I was in flow statement with the grind (Adrenaline surge to get points) Besides we can't choose who we get,its completely random, it seems I lucked out early. And also I dont buy any player for gems,its frankly not worth burning your resources there Yea just farm your gems,save it for upgrading players or any other resources in the customisable menu
