Out of those subs, I'd go with FA Luci / Vamp / Persephone / Hanzo. Other notable subs are: Gronia (combos with Pandora for a full dark board), Ronia (combos with Hanzo for a full dark board), Byakko (combos with Hanzo for a mostly dark board and has 2 row enhances), DValk (same active as Vamp but vastly superior awakenings).
For the most part, just stack orb change actives, skill boosts, and dark row enhances. You already have 2 quick orb change actives and 1 medium speed orb change active for a bigger burst so you have a solid setup already. A full board change would be useful for clearing jammers and the like.
I would love to use Ronia or haku but unfortunately I dont have either one of them. i was actually thinking of subbing out one of the orb changers, probably persephone or vamp, for the grape dragon. I have him ready to be max leveled/max awokened, has his 2 row enhance + 2 orb enhance + 2 skill boosts + movement time seems way more useful than another orb changer, especially when I am running 4 others(2x pandora, hanzo, and either vamp/persephone) However, I really don't run pandora that often so I don't know if those are actually more useful than another low cd orb changer.
