Curious to see how this will work out. I don't really like this card at all, but I am interested in seeing how it will fit into the game. I don't really think this will be playable, unless the meta is near-Minionless Priest decks vs. board heavy decks.
I don't get why you guys say it's bad and just a meme card. It will not activate deathrattles, moreover in many situations your opponent's deck will be weaker. I can imagine that we will see this card in action.
For all users who have looked at this card and somehow decided it was bad, allow me to explain how this card works.
This is a board clear that costs 1 mana less than Twisting Nether and also ignores Divine Shield, Deathrattles and anything else that may keep a minion on board. That's it. As Reynad described it in his reveal video this "might just be the most powerful board clear ever made in the game."
The only downside of this card is that you can't play it in a fatigue deck but that doesn't really matter because it's easier to machine gun them down with Shadowreaper Anduin anyway.
