I envision my ideal army as being strong and fast.
And I prefer to include units with a speed of at least 11 whenever possible.
But if we consider levels:
1 - Captain of Centaurs (speed 8)
2 - Storm Elemental (speed 8)
3 - Royal Griffin (speed 8)
4 - Vampire Lord (speed 9)
5 - Master Djinn (speed 11) or Thunder Bird (speed 11)
6 - Knight of Death (speed 9)
7 - Archangel (speed 18).
If there's a morale problem, the first level is replaced with upgraded Fairies.
The army is based on the hero having the Ballistics skill and not having the Archery skill.
