User blog comment:HQDominator/This Shouldn't Be Possible: Boost BB Gauge Each Turn/@comment-5714316-20160117062407

So what? This is called bb gauge momentum, every time a make a team i assure that i can ALWAYS fill ALL my units SBB.

My favorite : chrome ( bb fill on spark) + Andaria (  boost to bb gauge fill rate, boost bb gauge when attacked and boost bb gauge every turn)

Or libera ( huge boost bb gauge when attacked) + colt ( boost bb gauge every turn)

bestie is a bb gauge fill monster, she alone can easily provide a lot of bb momentum

Bestie ( leader: greatly reduces BB gauge amount required for BB & reduces amount of BB gauge consumed) (sbb: boost bb gauge fill rate and guge boost to bb gauge when attacked)

Andaria and Shera are also pretty good as leaders.

Really, there are thousants of way of filling your SBB every turn, is quite normal ( NOT op), and is also ESSENTIAL to beat the hardest stages of the game like trial 7  and 8
