I actually have War Incarnate and lots of Violet (full set of regular and the seasonal variant), magic doll faction pack was my first purchase ever, I got a playset of all of it. I think I prefer War Incarnate or Scylla. Why War? Because he lessens gain next turn, -2sp can fail if they have 0 but you cant stop the next turns SP gen.
I will go watch those replays now, and I have been looking at cards and trying to think how I would tweak it in the future or make variations of it. Just trying to get this down pat because most of the mistakes are generic timing ones, if I can get past those I will be alot better off regardless of file (my gowen file was alot more simple).
As to the assassin SS, I am trying to think how I would use that.. as usually that means losing lebeau or maybe mindsoldier, although it DOES perma remove the thing it hits which is nice and useful later. So maybe a 3rd or 4th SS? Hm
