Scourge of Frostholme ramp

With everyone running nothing but spells (nothing else makes sense) there is a huge meta hole to exploit - Scourge of Frostholme. This deck aims to survive and ramp into A new tomorrow and since Scourge is the only 10 cost unit in the game, we are guaranteed to hit it. This means that our opp most likely cant play anything the rest of the game so we win. I expect the biggest challenge to be either counterspells (do they even work?) or hyper aggro rally decks, but we will see how the meta shapes out. It might be right to play primal instead of justice for more card draw, lightning storm and decimate, or instead of fire. But kindle and harsh rule seem like allstars. I am looking forward to your feedback!
