New dark troop: 2 headed dragon

Name: 2 headed dragon
Training cost: 1,250 dark elixir
Training time: 45 minutes
Housing space: 20
Damage per second: 210
Hit points: 2400
Movement speed: 19
Description: the 2 headed dragon has two heads obviously , one head fires fire the other fires ice. The head that fires fire will do normal damage, but the head with the ice will freeze the target it attacks like a freeze spell just that it's a single target also giving other troops the advantage to destroy it.

I will never pay more than thousand dark elixir for a 20-housing space troop. It isn't so strong too, and it is really similar to the warlock posted by whammer, but with exaggerated HPs and cost and a useless ability to the second head.
