Arena squads you want to focus on early BB/high BC multipliers or Crit:

Which basically means make a squad out of these units: Bestie,  Belfura,  Colt,  Ophelia,  Dion,  Orna,  Aem,  Raaga, and so forth you get the idea.. Just look for your units that have BB fill/ or crit.

Trials you just want a well-rounded squad you can look up what a well rounded squad looks like on reddit forums.
