Army Ideas Options:Talingul = 100
Augamo = 155
Avernus = 135
Boreos = 110
Breach = 145?
Iron Golem (Un) = 100
Greater Ice Elemental (Un) = 130
Calibrax the Kyrie Warrior = 130
Rhogar Dragonspine = 110
Raelin / Kelda / Deathreavers X 2 = 80
Personally I think the best army (at 520) is:
Talingul
Boreos
Greater Ice Elemental
Iron Golem
Raelin / Kelda / Deathreavers X 2
If you have more points change GIE or Iron Golem for Breach or Augamo. I also think healers Rhogar or Kelda or Calibrax are valid options with them as a pack of unique heroes. Keep the healers nearby Talingul and at least one construct and, even if he/she dies first before healing, the enemy is concentrating on them first and leaves the constructs alone to do max damage.
