well, malice jewel + any sphere that boost bb is a very solid combo... if a unit requires a special sphere to activate the extra skill.. go for it ( zenia and vargas for example)

you want semira to be immune to status ailments ( even if a boss curse/paralysis your hole team semira can remove them)(Drevas for example)

your mitigator probably deserves the best BB filling sphere (Sacred Crystal is in my opinion the best)

If you have the heresy orbs (Heresy Orb,Fallacy Orb,Infidelity Orb,Impiety Orb) you should definitively try to use them.

Metal Orb  is awesome

Sky Harbinger  has the biggest damage bonus ( when full hp) and has a nice 30% hp bonus

Crit rate spheres are usefull ( but i dont like them) like Death Axe and

Spark boost spheres are good principally to units with high hit count on sbb(Heavenly Bud,Steeple Rose)

What i really like is spheres that can do 2 things Luna Laguliz( crit + stats), Heresy orbs, Xentar,Providence Ring(awesome for ultor/deimos), Blighted Seal ( for OTK), Phoenix Crown ( heal/bb every turn AND when attacked , yes please),Spirit Tiara, Guardian Shard ( awesome with infinite sbb like nemethgear or oguro)

There is not a real guide.. there are thousants of good spheres out there... You probably want to have at least one kind of stats buff.. mainly you need to learn WHEN you should use each one)
