Yes you are right the Liq Shadow is more of a use it if it is there. I also use it to nerf Otys etc.
Basically the deck works well upgraded but unupgraded you will struggle a little.
As upgraded I win around 19 out of 20 in T50, 16/20 Level 5 and 15/20 FG.
I still use it most in PvP as that's where it is most effective.
