To "Win most Rounds" you almost have to play one of those clans sorry.
Maybe max attack manip Jungo
Mono Skeelz has a lot of good round winners. Chiara, Sandro, Sasha, Falkenstein, Belgosi, Michael, etc.
I want to have fun and be thrilled by winning rounds and those 2 clans looks fun to play but i'll still think about it. or maybe i should wait for the next clan? Thanks
I tried it with roots but it seems that its lacking damage and it seems hard to win some
How about Bezerk? Their cards typically have higher power and their bonus removes two life per win... But then again, I typically play Rescue or Uppers/GHEIST.
Note: If you like Root's SoA, you could try GHEIST, but they tend have a lower power (but better abilities).
