*disclamer* just to start this of i am not some pro l33t player or anything like that and this just my opinion and it is subject to change.
tier 1-
GHEIST their bonus is just so damn stong and well their cards are much better than their counterpart the
Roots imo, i dont think they are the best and they have their weakness "like SoB" and their mono decks arent as stong with the recent perma banns
Montana that attack reduction is just insane, they have so many good cards like
Mona,
Griezzo and
Spiaghi probably the best clan, makes a nice mono or half deck
Skeelz so solid good in a half deck, mono and splash does pretty much every thing. nuff said
Piranas before i get started i have to say they are my main "well used to be" their bonus is really good, clans that need it like
Rescue and
GHEIST are just slaughtered most of their cards have huge power, pill manipulation is real strong Scrubb can just overpill and get away with it. Only down side half deck isnt so strong imo and their perma banns really make a difference.
Vortex their clan bonus is so forgiving and allows you to make huge plays and not geting punished for it, however the main problem is their bonus doent win fights. btw they are on the edge of being top of tier 2 but im nice like that.
ok so thats the end of tier 1 i just wanna say that thats not in any order and that if your favourite clan isnt there tier 2 is still very viable they just have down sides that tier 1 dont.
