when you have defeated all goblin maps there could be new "worlds" ,so after defeating sherbet towers and everything else.
world 2: gem world
get gems from raids (this could be a new way to get more builders)
world 3: dark elixir world
get dark elixir from raids (easier to get dark barracks troops and heroes)
(they could cost real money if you want to get them early...) (so supercell can get more money too)
Reply if you want changes
