Assuming you have a wizard and a BSB this is what I would do...
lvl4: Lore of Life, Moonstone of the hidden ways, Dispel Scroll.
BSB: Asyendi's Bane, Hail of Doom Arrow, Dragonbane Gem.
8 Dryads.

10 Glade Guard: Musician, Banner of the Eternal Flame.
10 Glade Guard: Musician.
10 Glade Guard: Musician.
10 Glade Guard: Musician.
9 Wardancers: Musician, Champion. (BSB and LVL4 hides here and keeps in a wood, ready to teleport to safety)
5 Wild Riders.

1 Treeman.
1 Treeman.
If you are able to get your hands on an Eagle I would drop 2 Wardancers and the champion upgrade to fit that in. Normally I prefer the Lore of Beasts, but with 2 treemen it's nice to to have the lore of Life the keep them up and running. Other then that it's all about earth blood on the bunker, dwellers on the enemy and keeping throne up and running. The last spell is hopefully flesh to stone to help you beef up any dryads who are in combat(preferably in woods so they are stubborn as well). Best of luck, and have fun playing!
