high khatun can be great use for early game, built in speed boost in all battles and a speed increease/turn meter boost as well, probably best lead role i can see for a cb team for u right now, doom presist would also be great, removes buffs and heals ur team every turn + increase attack, also orn might be useful for now for ur cb team since he has decent psn dmg, but either way dont sit on him, hes like a slightly weaker version of tedor and he can probably clear most dungeon content for you (my orn solos stage 25 dragon for me in around 4 mins while leveling 4 chickens at the same time) tayrel also probably super useful with his decrease attack on a1 and can also dec def.
