Ashertheil Ravenger of the Sky

Flying, Hexproof, Protection from Reach
When Ashertheil Ravenger of the Sky enters the battlefield you may destroy target creature with flying.
Ashertheil Ravenger of the Sky is the only creature who may have flying. All other creatures lose flying and cannot gain flying.
He flies higher than all, faster than all ever watching his kin. Even dragons cower inside their mountain when the God of the Heavens takes flight.
