I was lucky today that I got an evo card(SSR) , not sure where to use it though..
Naoe Kagetsuna(0 stars)
Takeda Shingen(0)
Kuroda Kanbei(1)
Mori Motonari (1)
Date Masamune (0)
Yamaga Maskage (2)
I think those are the best options from the generals I have
Note that I use Kuroda Kanbei in my formation as a heavy artillery, and non of the others are in my formation.
