I just got 0 stars in a clan war attack because the clan castle was too deep inside the enemy base. I tried sending a giant to lure them out but it got stuck at the wall. I deployed a bunch more giants and they broke through the wall and the cc troops came and I tried to drop a lightening spell on them but they moved too fast.
How do you destroy the cc troops if the cc radius is still within the boundary of the buildings? If you drop 3 lightening spells on the castle while the troops are still inside would it destroy them?
