It alldepemds on what u want hansel buile for plunder atk build for war with weak allies pure spy for mercing and griefing Etc.
Hansel Build: All guilds except for one attack building of choice. It gives great plunder, but you need defense potions to protect yourself from bigger hitters. Mixed Build: All beastiaries or aviaries, so you have the same attack and defense. You lose less troops per attack, but it takes longer to regen your troops. Attack Build: All forges or subterrean factories, which give you high attack, but you need defense potions because of your low defense. Pure Spy Build: All guilds, which leave you vulnerable to be hit and you have no troops, but the only way for someone to attack you is if you have money out. These are the main builds, and I still don't know the name of the build with all war cathedrals or summoning circles.
