This is the Xixo C’Thun Warrior Deck with Deathwing he used to win the Star Series tournament. Deathwing has become an inclusion in some Dragon Warrior builds but was interesting to see it in a C’Thun deck.
Your opponents will not be playing around Deathwing, that’s for sure. Not that it’s easy to play around a 12/12 that hits the board and clears everything. There seems to be a growing trend of adding more threats to decks, so Deathwing is optional but if you have it give it a go.
