Self attack simulator

The ideia is simple, simulate one attack in our current layout village using some money, elixir and gems (used to rebuild our village from the simulate attack), the troops used is refunded (simulate the attack nobody gets kill). Delay 12h, can use gems for faster attacks. The attack price should be ~ 500.000 gold and elixir and something like 10 gems. 25 gems to get an instant attack instead of 12h delay.

Well it should be just a test to see if we can defeat our own village so it should be free instead of attacking with money.(like friendly challenges)
