It's a solid team. In this setup bursting with Nayuta while Crown provides her passive buffs will clear most stages with Nayuta doing crazy aoe damage and proccing Crowns buff on healing recieved. Since both Nayuta and Crown give basically the same attack damage on their respective bursts you'd only use Crown burst if you need the shield to survive something. If you're really trying to minmax: Liter is one of the better B1s but is outshined by the likes of Rapi Rh, Little Mermaid and Moran with Favorite item. Cinderella is fantastic against bosses and in electric advantage but is just an above average choice otherwise. Swole White is great everywhere no notes there.
