I've been thinking a ton about the Marshal of the Kriels. Here's a list I'm running in an upcoming Steamroller. I'll be play testing and sharing my thoughts on her soon.

Battlegroup
Grissel 2
Dire Troll Mauler
Troll Axer

Support
Fell Caller Hero
Janissa Stonetide
Champion Hero
5 Champions + Skaldi
10 Fennblades + UA
War Wagon

I'll say this, I'm worried about a lack of ranged support. The main reason it isn't a huge concern is the speed with which those Fennblades can get into my enemy's lines. Dash + Fennblades mini-feat is crazy.

More soon.
