Not many sources for web yet. Best I can do is:
Gorgotha
Spider Knight
Reaver
Tal’Rae
Three elves for bonus, with two elf bonds. Also, three Zhul’kari troop bonus. Having two commons fed by an exploder buffs Tal’Rae’s arcane pretty quickly.
I’m using:
Spider Queen
Reaver
Dark Maiden
Tal’Rae
Wild Plains Banner
