Don't have any defense towers, and do straight hauntings, cursed forges are a good way to go, Hansels have trouble hitting hauntings without pots on the attack side, it really depends on what kind of finished build you're looking to do......
I like the hansel build, but unless im in a PvP I keep 5-6 lvl 3 subterranean factories and the rest guilds. When im in a war I drop all but 1 or 2 factories and build either defense towers or spy defense towers depending on who we are warring. Its easy to do when you have money stocked up,
