Hi, you can go to CLAN DISCUSSION area and create a new topic about you and what you want and can do.
Also you can read about clans and what they require to be part of the clan. Sometimes they bend their rules according needs but they have their basics. You can apply to their clan threads.
Tell your rank, how many wins can get per season 1v1 2v2 and 3v3 as example. Fight titan, tickets collections, war.
