dragon tower

how bout a dragon tower armed with an aerial defence maybe a harpoon or sumthin that houses troops that are trained with elixer or dark elixer that specialise in only hunting dragons , by every upgrade the housing space increases as well as the aerial weapon ,but just to keep it fair these troops can only attack aerial targets

You have some interesting thoughts here but we do already have air defenses and although full dragon attacks are WAY over powered this would be a little too much
