Just by looking at the name,it is obvious,just like a wallbreaker.There are 2 types of the Trapremover,ground Trapremover and Air Trapremover.The trapremover is deployed to trigger traps such as bombs,giant bombs,air traps,seeking air mine and spring traps. When deployed,the Ground Trapremover will run into an opening of the base made by wallbreakers or other troops,it will detect and run onto spaces in between buildings like how a wallbreaker detects walls.To avoid being overpowered,the Trapremover has almost the same stats as a wallbreaker,except that it is slightly faster and has an increased health point. Trapremover can change the fate of the battle like a wallbreaker. It is very effective when using hog riders and balloons since these troops are really weak to traps. The details I leave to SuperCell to decide if my idea is accepted. Thank You!
Why not just spawn barbs and have them trigger the traps instead? Oh, and programming the units to avoid revealed traps would take forever. A coding nightmare.
