New Air Troop?

I still haven't worked out the details but for air troops it seems that they are all equivalent to some type of ground troop.
ex: barb/archer=minion
pekka=dragon
golem=lava hound
wizard=balloon
giant=?
See how most troops have an equivalent on the ground or in the air but the giant has no air equivalent. So I was thinking that there could be an air troop that takes a large amount damage but doesn't have big amount of power. Now it wouldn't have as much health as a lava hound maybe like 1/5 of a lava hound. This obviously doesn't have very much detail to it but it's just a small idea. Please voice your thoughts on it down below.

I think the equivalents are just a coincidence, and that there is no need for any extra air troops.

i think giant works out as a lava houn too, and a wiz dosent have an air counterpart
