New dark troop

I'm not sure what you could name it, but you guys are very smart at supercell, u would think of something.
Ok so, what it does is, It's a flying troop, and after it gets a certain amount of damage, it drops to the ground, and becomes a ground troop until it dies, i think it should have similar hitpoints as a pekka or golem... but its ur choice, and have it drop from air troop to a ground troop after retaining a certain amount of damage.. Example: take 50% health of it flying, so it drops.
