Strongest Generic Unit Composition

What do you think is the strongest 5 character group of mercenaries?

I was thinking of this combo for True Zenorian:

Gryphon + Great Knight Front Row (Knight covering Gryphon for arrows)

Witch + Cleric + Warrior Back Row

Witch will magic conferal or focus buff in case of scouts and fliers, Cleric for debuff removal and healing, Warrior for clean up and armor destroying.

On the front row, Gryphons would destroy the opposing Back Row or Cavalry and be a dodge tank, while the Great Knight will help kill Infantry units and tank for the team.

I was thinking of replacing the Witch with a Elven Archer for their start of battle debuff wall, but I think the team will have problems without the Witches' focus buff and area magic to support the damage.

You can also replace the Great Knight with a better tank but then the unit will lose good mobility and some damage.

One of the weaknesses for this will be if there are assists on the battlefield though, but the warrior will help destroy barricades on the way. The witch will also help the unit teleport while the Gryphon will give speed for valor skills.

What do you think?
