Yes they are in my defense team, which are my only max 5*'s (and one 4* max with emblems):
Melendor+7, Magni, Kunchen+5, Gravemaker+5, Poseidon
I have Liana almost maxed at 4/50, and am leveling sartana and joon (but dont have mats to get them to 4th asc) then I got Kage and Seshat today! - I think I will level Kage first
Also have Frida and Azlar stuck at end of 3rd asc., and Ursena and Mitsuko at 1/1
I think I’m gonna go with BT to 7 and Poseidon and Magni to 1.
Leaning towards when I get 9 more emblems to put that next one on Poseidon and swap his position with GM
