New Dark Elixer troop! (Gryphon)

The troop Will be a flying unit that can attack both ground and air!
The reason why i chose this was because there isnt alot of flying units, so what i came uo with was this. Here are the stats
Name of troop. Gryphon
Training cost. 500 DE
Housing space. 15
Damage. 175
Movement speed. 24
Hp. 800
Th reach 8
Dark barracks required 6
Description- The gryphon came to be an unbelieve creature, the dark elixer has changed this freak of nature into a wild beast! As it attacks its vulnerable to teslas and wizard towers, as it does 2x the damage. This unit can also come down to attack as well. When its on ground the effect of 2x the damage fades away, as it can be attacked by everything.
Any thoughts?
