Need help with a good war defense

I have currently from left to right
Kunchen Kara Alasie Marjana Mother North.
Any advice on positioning and who else may be better to use in defense for war. We usually have blue tanks.
Mother North and Marjana have costumes but not fully leveled on costume.
Kunchen and Kara emblems to 10 and Alasie Marjana and M. North emblems to 20.

Also any help sorting out my roster feeders and who is priority to help me offensively and defensively. Thanks in advance
