I personally think this is a very well designed card. It's very situational, but when you find the right times to use it, it can provide a massive tempo swing in your favor. Also very good when fatigue starts to kick in.

My only gripe is that I wish it was 4 mana. That's probably way too good, but I'll feel better about it as it rots in my hand.

Awesome as last removal, if your deck is empty you can remove all enemy minions without burning cards (and ZERO fatigue damage)

Fuck this fucking card. Who the fuck at Blizzard made this?

I actually had this happen where this card was vital in winning my game.

This is the worst DK Card and the best DK card.

vs Aggro = bad, you lose your deck, maybe key cards etc.

vs high healthy minions you lose only 1,2 or 3 cards and you have a hard removal for only 5 Mana

No it is bad against control... it is very good against Aggro  though, you just wait for them to empty their hand, play this and put any taunt in play and you won. "Key" cards against aggro don't matter because they might as well be at the bottom of your deck and you still won't draw it. Get this from Arfus and you have a way to stabilize against aggro decks, if you got this from The Lich King then it doesn't even matter, aggro deck usually cannot deal with 8/8 taunt without losing anyway...

Won't know until release for certain, but it sure looks that way.

Does this work like Fel Reaver in fatigue?
