Among Michele, melchio and sagahvel. For me Michele is useful evolving to 7 star. Why? beause of her attack buff and crit buff. If I'm going to rate her SBB, the attack buff is 9/10 while the crit buff is 7/10. It's quiet fair 'cuz michele will be equipped with Duel's Fragment (Boost HP and ATK by 30%, boost critical rate by 20%, 30% chance to ignore enemy's defense, and boost BB gauge when critical hit occurs (4-6 bc)// Therefore, Michele will have a 60% crit buff to herself+140% attack buff and not to mention its possibility for ignoring enemy's def and BB fill when crit occur.

PS. Her SBB is 16 BC only. Easy to spam.
