I suggest you train Zergel (he's one of the best atk buffers boosting 140%), Arus (Unlimited SBB), and Darvanshel (Elemental advantage and good mitigator)

I also think you should replace Semira with Arus to maximize damage. If want more damage you can switch out Shera for Darvanshel.

This is all under the assumption that these units in their 6 star forms and you have enough cost
