Swap Sartana and Thorne’s position and you are ok with Horghall and then when Evelyn would be ready swap her with Thorne.
Boldtusk - Thorne - Justice - Horghall - Sartana
Boldtusk - Evelyn - Justice - Thorne - Sartana
The best tank would be Justice, followed by Thorne and Horghall.
If you want to put emblems (def > hp > atk) on your Boldtusk then he would jump over Justice and you could use Joon, with Sartana covering him.
Evelyn - Thorne - Boldtusk - Sartana - Joon
ps. I wouldn’t put Domitia over Sartana in a defense.
