Hey there KaW!! Trying to go spy and wondering if I should either upgrade one of my level three spy buildings or use the money to build the rest of my spy buildings for I still have alot of my attack buildings. Thanks in advance.
I would build a lvl 4 then wait til I have another bil before selling another attack building. then build to lvl 4 guild again and repeat. That's how I did it on my iPod acc. (this one is iPhone)
