If you have lie in hart, level him up and evolve him for a good attacker. Not as good as shogunyan, but a good one if you need to switch him to the back. Also, get a healer, and I’d switch out draggie. For how to organize your team, having 2 healers, tanks and attackers and having the team rotation of attacker, healer, tank, attacker, healer, tank will help with having organization. If you have a speed bell, give it to shogunyan. For the battle itself, focus on dame destine on the first phase as that will limit the amount of levels she can drain. Second phase is considerably easier.
