The Roots don't have an official Leader; they seem to be more of an anarchist group. The closest they have to a Leader would either be Gertjan (most politically active, attempting to make the group more known and influential) or Kiki (mascot/symbol the clan can rally behind).

Roots don't have a Leader because that would be too close to society and thats not cool man.

Uppers also don't have a Leader but thats because they all think they should be the Leader.

After playing around a bit with Frozn, some thoughts spring to mind. This clan is completely unviable vs. SoB. It will probably always have a disadvantage against SoB but some abilities might allow you to at least compete. Someone with their own SoB, and cards with some Courage abilities like +dmg or -life would help. These abilities could also prevent their meager damage from becoming an auto loss vs. Pussycats.
Frozn is a fun clan that hopefully can be well fleshed out with upcoming releases.

Um_AaaBattery, well, we could go with the richest of them, Zlatar... I think

@SMAINODOR, you do realise the Game of Thrones can't, and doesn't own the sentence 'Winter is coming', right? It's just a statement that winter is approaching, which is true in France. Though it is most likely a homage to the show.

@tititoro: He is kind of shown as a Leader in the comics but there is nothing about him being the Leader in any bio.

Also, peetelafoote, you're a bit off on that "vs sob they're bad" theory. Right now half their cards are sob-proof (those being Annuqa vs Nightmare/Piranas, and mikael).

We only got 5 cards and people are already judging the entire clan's usefulness against SoA. :

Haha, LetheanTears speaks the truth.Can we let the clan get at least 12-16 characters before we start judging them? From my own testing, they seem... ok... They have the potential to be really broken, so UR should watch out with what they do with the clan. Another thing I've noticed is, that since they're new, people don't really know how to play against / counter them yet. I personally didn't care too much for the Berzerk clan, their art didn't appeal to me, but these guys seem interesting thus far. So, keep up the good work UR!

@letheantears, wrong, SOB, not SOA... lol

Mikaal and Annuqa can counter sob clans, and Mikaal sob in general, unless if all stops. I believe that means Dieter, Glorg, Spycee, Kristin, Baba, Burdock, Shakra, and Leviatonn. Mikaal can easily dodge around 2 of these(Baba and Shakra)...

In addition, ayzkun is still an 8/2, tiwi gets his effect through losing anyway, and niqilodas ability contradicts bonus, as a good way to potentially counter SOB or SOA.

Therefore, that leaves future Frozn to decide faite against SOB.

@UM_AaaBattery, true. He is basically there figurehead if you will.

The Roots, Uppers, and leaders definitely have no Leader... Yet...
All Stars has Eyrton
Bangers has Bodenpower
Berzerk has Cortez
