The costs and requirements of each upgrade in this game can take time to aquire. If you have the ability to get help in an alliance or by building farm accounts you will have a free advantage. Otherwise, buying packages from the game Daily Specials or Limited-Time Packs might be the faster route. Raiding is a very big part of the game. So be ready for wars offensively and defensively.
