Some quick thoughts:
Priestess and Forcemaster:
--Priestess heals and brings the creatures, Forcemaster buffs and debuffs.
--Forcemaster uses Battleforge and mind spells, Priestess brings Temples (including Dawnbreaker) and condition-removal.
Necromancer and Necromancer:
--Focus on zombies. 8 Zombie Brutes by turn 10? Have fun!
--Have one use a Battleforge and pack doubles of the best equipment, including Necro-only gear.
--Make sure someone brings out the Ziggurat.
Straywood and Johktari:
--Make heavy usage of the totem conjurations.
--Johktari uses Lair and builds slowly, sniping as she goes. Straywood uses Battleforge and plays aggressively.
Druid and Priestess:
--Best turtle mages in the game, working together.
--Use Vine Tree and Temple of Asyra. Have at least one Battleforge as well.
