new dark troop idea-dark dragon

Attachment 168138<---this is my troop idea, it is a dark dragon, it has a head and arm made of stone and another arm made of steel
after sleeping underground for eons, the dragon has reawakened to find that it's head and left arm has stone formed around it and that it's right arm is now made of steel. it is now the dark dragon.

the dark dragon targets builder huts, army camps, and both types of barracks, the buildings most left in corners of villages, that make most raids less than 100%, meaning that this dark troop won't let you get an unfair 2-star. this troop also has ranged explosive rocks when dealing with defenses, (except mortars it is terrified of those, and will get hit by them, taking 2x damage) and a powerful sword when against all other buildings. and when this troop is in a clan castle (*cough*or clash royale*cough*) it targets all troops that can hit air troops, meaning that this troop pairs perfectly with minions, dragons, balloons and the such. also, this isn't my final design, as this was made with parts of a golem, dragon, and pekka, for I do not own a good editing program. so you could make the design better for the main game. this troop takes up 15 housing space, less than a dragon, but takes a whopping 50 minutes to train, and 600 dark elixer to train. what separates this troop from other dark troops is that you need elixer to upgrade! it also isn't the fastest troop, as it's movement speed is 6. but it's attack speed is a wonderful .5s when ranged attacking but 2.5s when melee attacking. it's attack strength is 360 when melee attacking and 98 when ranged (with splash damage). if this troop makes it into coc, it would be one of the most interesting and special troops in the game, making it very fun to mess around with.
