Hi guys. Just want to share an idea about how to get easy coins. I'm on league 10 and being lucky enough to beat everyone, (no offense). By beating all teams, I gain 20 x 9 = 180 coins within few minutes. Once being at the top, I change my team to a single weak unit so everyone can instantly beat me. When I got beaten, the winners gain 20 coins with ease. Then once I revenge all every teams, I gain 20 times teams and change the team to weak unit again. Suppose if everyone do the same by changing their team back to single weak unit as protecting team too, everyone will gain free 20 x 9 = 180 coins many times a day. With unity, the amount yield could even reach several thousands in no time, far more efficient than 5 crates as a prize.
