As other commenters have stated, Hadaron isn't needed because it clashes a lot with Avant and Charla, so you'll need to subsitute him with another Def buffer.

To compare Offense vs Defense, Defensive buffs clashing can be good because you'll never know when your enemy will destroy your squad, when compared to Offensive buffs where clashing wouldn't matter much. So it's better to replace either Hadaron and Avant or Charla with other types of Offensive buffs or prepare at least 2 Defensive buffs.
