pitfall

so i was thinking, wouldn't it be cool if there was a 4x4 hole in the ground to hell? yea it would be cool..it would cost 15,000 gold and take out all the troops that fall onto it. once it is activated it stays a hole but i think the a.i. should go around it. but it is a good trap to protect stuff. you get one at TH(town hall) 7. and you get two at TH 9 and maybe a 3rd at TH 10+

for example if there is an open space in your base you could put a pitfall trap right on it, so when the troops spawn they just fall through the layers of hell.. and if they try to keep spawning they will keep falling. i think its a cool idea, leave your feedback negative or positive THANKS!!!!

cool but would it be hidden and when the troops fall it to it will be revealed? make it clearer.

This would probably be too overpowered because pekkas,witches,hogs,golems could fall into the hole?
