Here it is... it's just a thought:
4*: Graks and Yayoi
3*: Uranus and Sigma
2*: Ella, Britanny, and Na Boh (or Nimistiec)
Seems good. 4 Cards can decrease 4 or 5 damage, like 6 Threats, but somewhat weak to SOA.
What do you think?
Nice deck. I would personally use Wakai instead of Na Boh.
I'd change Ella to Wanda to remove some potential SOA gimpage.
