I believe there will be warlock control based on spells ( like black control in Mtg ) in future so this card will be usefull

I've started using this to counter varion er whatever in my   malylock. Its actually pretty decent.

Though it was a hard-to-reccommend card before, I think this card would see play in TGT in Dreadsteed decks. By that, I mean decks which combine Dreadsteeds with Baron Rivendare or Kel'Thuzad to multiply their unkillable Dreadsteeds. Oh, everything on the board just got killed? Make that everything on your opponent's board just got killed.

I don't think there would exist a single warlock deck without this card if it costed 4 mana.

I hope this will be better with blackrock and ,, X card costs 1 less per minion dead "

For 8 mana : All minions trigger their deathrattle

It's still deadly & epic.

My god does this card suck, but it's still worth playing for two reasons:

I. It can bail you out of a losing situation with a lucky top deck.

II. It's board animation is epic.

Bad card but quite possibly the best top deck in the game in a losing position

I think the mana cost is just right for this card.  By turn 8 your opponent would most likely have heavy hitting minions and legendary cards so when you bring this out they've probably lost their ace cards.  I always have one of these in my deck and saved me a lot of times.  The animation is really cool --- it's an implosion Of purple light.  The problem with this is it's weak against minions with deathrattle -- haunted creeper, cairn bloodhoof etc.  they will still spawn.

The animation is beautiful... I always wp my opponent when they use this card, to thank them for the prettiness.

Anybody has a video of this? I haven't seen this animation yet, everybody says it's the coolest one!

Love sucking the opponents expensive minions into the void.

It should silence the minions first, like Earth Shocl...

I think that would make it to powerful sadly, also it would ruin the combo potential with your own deathrattles ^_^

Twisting Nether 

I would use Twisting Nether  card if it Silence + kill all + gives you a one cost minion Voidwalker.

Silence just makes sense since they are launched into the void, would balance the card nicely.

I think the Voidwalker is a bit much, but the silence makes total sense for this card, and even then, it may not see play anyway.

Overcosted by 1 or 2. Quite unfortunate too, since it's such a cool card.
