I would suggest using Avani (more on damage) or Avant (damage and survivability) as leads, then the sub units are as follows:

Avani/Avant (Choose one for lead, choose one for sub unit)

Either Elimo or Krantz as mitigator

Elza, for the BB per turn and bb gauge fill when sparking

Kanon, removal and nullifier of status ailments and Def Up Buff (Really helpful)

Reud, BB fill when damaged and HP per turn

Optionals: Rahgan (If you want more damage)

The trick to Gazia's trial is burst. If you burst him enough on a certain threshold, he will not do many powerful attacks. Also, look out for when he stealths since you can't hit him with targeted attacks. I would suggest bursting him from 40 or 30% on his second form so you could avoid the 20% threshold, Holocaust. That's all I have to say, I hope I helped owo
