I see that you actually have deemo, sgx and doug, which is a nice units for unli SBB team (though I heard that doug alr got nerfed and due to recent bug, I have not test him again)

but you might consider to use:

Deemo (5* and lead her), sgx (crit buff & fast SBB fill rate), doug (high hit for easier spark), leorone (for the buff) and additional 1 units, I will not recommended unit with slow BB/SBB refill rate like gravion and azael or one target cause you plan to create unli BB/sBB team, which might not what you want to bring to boss battle with low number of target.

my suggestion for last slot, you can put units like lunaris for her anti debuff SBB, though she will be kind of hard to fit in with her slow SBB fill, but her fast atk might be easy to time her spark.

good luck~
