CB help
so as the title says i need help with CB I recently came back and know that clan boss gives insane rewards but i cant build a unkillable team because I dont have the champs but i feel like my selection of champs can do a decent CB team if anyone here has any reccomendations of who I should use or what team comps work please tell me( i can also 6 star whatever champ so dont worry about what level any champ is)
