It clears the board for 1 less mana than Twisting Nether, and doesn't trigger deathrattles. If your opponent has lots of small minions on the board they now have to draw them again from a diluted deck. If they played Spiteful Summoner they now have an extremely slow 10 mana minion that they probably won't bother to play once drawn.
