Seath The Scaleless

Hexproof, Flying
When Seath enters the battlefield exile all other dragons and you can play instant and sorcery
spells this turn without paying their mana costs.
The albino dragon, Seath the Scaleless, was born
deformed and blind, lacking the stone scales that gave
his kin their immortality. When war broke out
between the dragons and the newly empowered Lords,
Seath betrayed his own people.
