Spies

Create spies that would be trained in the barracks. When deployed the spies would run very quickly thru the village. It can hop over walls, but it can be shot down with archer towers only, or wizard towers. As it runs thru the village, all the bombs and hidden traps with in the range of the spy, however large or small that will be, will be shown for a very short time (1 - 3 seconds).
