General gameplay tactics and its features.

I'm playing as Necropolis, and I build the buildings in the following order: Town Hall, Transformer, Tombs, Citadel, Castle, Graveyard, and Guardians. By that point, I don't have much money left, but it's enough to buy troops. With this army, I capture mines without any losses and rebuild the city's economy. So far, this tactic is working for me.
