Fengxin is in a very good shape now focus on team games every day. in my opinion, Yo, Vivi, Lyx is top 3 followed by Fenxin. Jibatong is also good but his performance is unstable.I will say they will form only one team based on the players you listed there.
Recently, Fengxin is out of shape and only play fun games. CL and xiaofan kind of quit, d8_baby not active, lovecheng may only play China Z for fun. The real China team may be: Yo, Lyx, Vivi, Jibatong (Lovecheng).
I don't think Tim can manage to form a team at this moment, even himself is kind of inactive.
