New army guy/new defence

Hey guys here's another good idea that I though of but this one too is in two part. So first it would be a new guy that attack the defence first. This guy would be like a mole so it could go under the ground and come out and attack the defence. This guy would attack with his calw and do 60 damage per second and have 55life. With that new guy come a new defence to block him so I though of like an electrick tower that electrified the ground so it would hurt the mole and plus it could hurt all of the other army and it could just be an upgrade to the hidden tesla. Or, I though that they could add some underground wall. I hope you take my idea.
