Its good, but you might want to keep Lira's BB lvl only up to 9 and don't bother unlocking her SBB, since her SBB is single target and at a very low cost at 30 BCs to fill. W/top tier BC factories like Elza and Selena, filling Lira's SBB gauge is a simple matter. If you have her SBB unlocked, she'll be a liability and I suggest switching her out for a different unit.

At higher arena ranks, you might want to change your lead to a unit that boosts HP, ATK and/or DEF stat paired w/units that have high BC production like Selena since you'll be encountering a lot of 7☆ and knocking out as much enemy units in your turn an possible while simultaneously  surviving their return fire is the usual pattern. It also helps, since if you have the random rules ticked on, annoying rules like empty gauges start or status ailments inflicted can mess w/your win streak.
