I swapped out one of the spectral sights.

This deck is pretty decent. I have 56% win rate from 16 games. My advice is try to pressure the opponent early game with Battlefiend, Chaos Strike. You should try to damage the enemy to summon Frenzied Felwing very early which will overwhelm the opponent. In addition you can use Raging Felscreamer with Escaped Manasaber to summon Priestess of Fury very early. Metamorphosis is helpful in finishing off the enemy. I also added in Kayn Sunfury.
