You can't eat your cake and have it too. It's either you start like every rookie by forfeiting all your money, packs and tokens or you continue with your team.

I'll take the later if I was you. That way I keep my money, packs and token. All you need to do is sell all your star players and keep only low quality players at the end of the season. Day 1 of the new season will be your reset. And you make a better chance for yourself. Good luck.
