Minion Steed and Anti Gravity spell

I always loved roman battles,and might've thought up a dark elixer hero like the minion.Think of it as a way to get in by making 1 hero fly in but cant attack while in the air(not even archer queen).The ability could be gaining health and the hero would recieve low health(hittable by all air and ground defences.Also a new trap would be useful,like the anti-gravity trap which makes all flying troops fall down to the ground for a few seconds but only 1 can be bought for like 2-3 thousand and max lv would be 4(total of 16 seconds),but flying units get more health too,making it fair.It would be good if it was added.
