I understand that some or may I say most cards have the annoying clan bonus that makes their cards special(namely Montana, Roots/ghiest, Uppers, Jungo. So I made a deck made up of an SOB clan. I don't know If I should go for a mono Nightmare deck seeing as Nightmare's amazing cards are expensive(since my deck is composed of power/attack/damage manipulation) I thought of buying some of Pirana's pow/dam/att reducers namely Tula and etc. But I don't know, Most of the things I hear from other players are Kolos' incredible 1 hit KO and never what the other cards do.
As of now my deck Is as listed:
(The extra clan)
(The extra Leader)
all in all that's 25 stars.(building a T1 deck in case you needed hearing.)
