Since its mono skeelz then your first priority will be Sasha (and can be used in T1 later on)
Chwing not so good (somehow i am prefer Aigwon Noel SoB event its situstional condition)
Drake not so good enough too
So its between Greem and Damian, and i think Greem will be better (Greem + Ambre at first round )
Save the ctz! and move on to collecting or building another deck around another clan.You have the cream of the clan,so unless you what to start building an ELO or T1 deck etc, why bother with the rest of the clan?My pick of the cards you have listed?Damian cos if you are in t2 then you will face high damage cards ,and he is 8 power.Oh I don,t know,Greem cos of her mission?
Skeelz isn't really ideal T2 clan...
I'd either suggest you do a 3-4 Skeelz Ulu Watu split with Ambre, or go T1 altogether
But here's a mono deck anyways:
