A.ALuci makes three dark orbs, so a second one isn't terrible, but that's a big investment and his active isn't really good enough to use over the large variety of better orb changers.
On further study and after the switch to Arena 2.0, it looks like Okuni is gaining popularity over A.Loki for the team. You aren't likely to oneshot Kali that way, but the faster countdown and the delay versatility against resolve and damage shields is significant. Since the team plays much like old Beelzebub, healing and stalling for actives makes sense compared to an overwhelming power burst.
Double A.Haku is acceptable, especially since using one or two A.ALuci actives can fix boards to near perfect row setups. It's better to take a heart/dark orb maker, but you work with what you have. Diadem is fine (edit: it's not God or devil, so not very good), Zuoh drags down the team because of his RCV, and the farmable Grisar is great if you want to dedicate the resources to him.
