They seem incredibly powerful then, even the heroes by comparison cost 2 gold a turn to keep in your army. These have no upkeep, count as a troop, and provide some great abilities (Elephant makes all rolls a 3!).
And you can even make special attacks with them (without using Ares)!
They certainly are very powerful to the point, that in my only play with them many players agreed that they "break" the game too much and haven't used them since.
