Dark troop the bomb thrower
How about making a dark troop called the bomb thrower. The bomb thrower has a crazy taste for destruction he likes to throw bombs over the walls and take out enemy defences. He has the strength of a wizard but with little health. The bomb throwers movement should be the same as a wizard. It should cost somewhere between 100-350 dark elixir to make a bomb thrower. Once the bomb thrower is upgraded; at level 2 it should start throwing fire-bombs to do more damage to enemy defences. Also the bomb thrower has unlimited bombs just like the air balloons. The bomb thrower should be unlocked at townhall 10.
