Deathwing will obliterate your opponent's side of the board. However, it will cost you your hand, meaning that if your opponent is holding Deadly Shot or Polymorph or Assassinate or any other efficient kill spell, you will be extremely far behind. For this reason, don't play Deathwing unless you know your opponent will not have an answer during their next turn.
Deathwing the Destroyer,formerly known as Neltharion the Earth-Warder, was one of the five Dragon Aspects and leader of the black dragonflight. Thousands of years ago, Neltharion was empowered by the Titans with dominion over the earth and the deep places of Azeroth. However, driven mad by the Old Gods, he turned against the other Aspects during the War of the Ancients. Among both mortals and dragons his name became one whispered with a feeling of fear and contempt.
