New Strategic Hero

In the Name of GOD
I want to share my Idea about new Strategic Hero. It's simple. I think about a Hero that basically is on ground and attack like wizard but after some levels (may be 5 Level) She/he can get fly ability. Barbarian King after five level unlock ability that make him to produced five or more barbarian and get speed and health. in this case Hero unlock ability that add wing to it and flying. ( and also can Increase Speed and Health recovery).

Advantage:
It's may be an strategic units because It first walk and didn't trigger air defense But can be target by mortar and canon but after flying can target by air defense but can not target by mortar and canon. It's the main flexibility and strategic side of this new hero.

Appearance:
In my opinion it can be walking animal like Frozen Dragon and after unlocking ability make flying. It can produce some little dragon (like minion) in flying mode. His\her speed on walking mode is little (like 12) but health is great (like 1500) and in flying mode his speed is increase twice but health be half (after increasing health). he\she has area splash damage like wizards (Ice breath) and slowing target structure or units by levels.
This feature and others can be change by supercell designers & developers to be balance.
I only want to share My Idea With you and I hope you enjoying.
Thank a lot.
