Brave Frontier

I can't manage to get 950k for the sphere frog in End8.

Any suggestions for my squad?:

Current: Cost = 95
Lucina 5* lvl 85 BB4 // Halloween Sphere
Uda 6* lvl 99 BB1 // Medulla
Ramna 4* lvl 60 BB10 // Holy Robe
Michele 6* lvl 100 BB5 // Sacred Jewel
Azael 5* lvl 80 BB4 // Muramasa
-with friend Maxwell, max = 750k ish

Other available units (I don't have much to work with):
Ulkina 6* lvl 28 BB1
Rowgen 5* lvl 54 BB1
Darvanshel 5* lvl 65 BB1
Shida 5* lvl 80 BB3
Lorand 5* lvl 79 BB4
Hogar 6* lvl 73 BB1
Golem 5* lvl 80 BB3
Zellha 4* lvl 60 BB2

Seeing as I don't have SBB on Michele yet so that she can actually use MTBB, and I can't fit any better units into the team because of cost, what can I do to raise my score?

No Burst Frogs from Honour Summons to spam on that Michele to at least get SBB1? :/

Not much you can do aside from honing your Sparking skills and trying out random combinations that may or may not work. Maybe even try a different leader, someone else who can bestow Elemental buffs (Lodin, maybe?).

On a sort-of-but-not-really-related note:

 Sphere Frog get!

Surprisingly got one within ~650 summons. Still have about 80 to go.
