My first trial list:
Kurnoth hero with scythe
kurnoth with bow
2 tree-revenant
2 spite-revenant
4 driads
960 pt
I could put sword hero and put another tree-rev, but I prefer the damage output of scythe. However, I will try both ways
Kurnoths
They seem very strong, the bowman has good range and damage.
Spite-revenant
They ability is much tactical, but they are fragile. I put 2 as support
Tree-revenant
They are fragile too, but their teleport ability looks necessary for objectives
Driads
Low str and armour, but they are fast. I would use them as screen for my Scythe Kurnoth
