New Troop

.The new troop I want is the Hydra. It has three heads and instead of targeting one building, Each of the heads targets a building and its a dark troop. Each Head does 260 damage per second. I have not thought of a design so supercell can do that training cost for it is 20 Dark Elixir. Capacity for troops is 10 or 15 and speed is just like dragon

20 De for 200 damage per head?you need to workout the stats of the troops.
Try referring the Anthony Vince's troops and spell guide!!
