Clan TFZ2 is a Sub-Clan too ClanTFZ, both clans (TFZ/TFZ2) is controlled by TFZ's Council, same clan rules in both of the clans, same inhouse games, same rights, but, as TFZ is the "mother" clan, the best members from TTFZ2 will be promoted to TFZ, from now on, when somebdey requests to join TFZ, they have to join TFZ2 first, after, they can be promoted to TFZ, depends on skill/manner. But the clan war teams will be skilled as TFZ, both TFZ/TFZ2 will have equal skilled clan war teams, a combination made out from the best players of TFZ/TFZ2.
About Council.....only TFZ members gets promoted to Council members, thats the highest clan rank in both of the teams, when you first hit council, then you join us leading both of the TFZs.
