Luna Pocket Galaxy with a attack restriction

It's usually a buff if you build your deck with this in mind. 

Warlock often gets these very interesting but highly situational and ultimately unplayable cards. Sadly this seems like one.

What

This is definitely an interesting card. Can't wait to see what crazy combos come from this.

In general, a fair number of high cost minions with low attack (but good effects) are available here and the swap is just 100% good for the person using this.

Maybe the only drawback is being 6 mana, so you might be drawing your "swappable" cards before you play this.

By the way I would use this occasion to encourage people to try out playing Wild. It is so rich in deck lists and different combinations, that it simply never gets boring. Just think of how many configurations can Deck of Chaos have - even with Hir'eek, the Bat or the Old Gods. 

Great tech cards in this expansion so far, there will be a lot to try out in the first week! Cheers!

Interesting, but I think warlock will still be too bad to play this.

How will this work with giants?

Why wouldn't the giants swap attack and mana just like any other minion?

Giants don't have cost-reduction while they're in the deck or on the board -- they only functionally reduce in cost (due to their own effects) while they're in your hand. So for a Molten Giant, it would become a 20-attack, 8-cost minion in your deck (due to Deck of Chaos's effect). Once you draw it, its 8 cost would be reduced by 1 for each point of health you're missing, so if you're at 22 health or below, it would be a free 20/8 minion. Not bad!

prolly going to be a bad card unless warlock can get something that really makes control works so you can float a 6 mana do nothing on play.

Cant wait to open it in my first 10

4 Mana Maly-GOOSE?

Yes please!

A 4 mana 9/12 Malygos, at that!

works similarly to luna's pocket galaxy, but requires more attention to deckbuilding

a nice addition to warlock malygos decks

OMG! This card and:

N'Zoth, the Corruptor

N'Zoth, God of the Deep

Yogg-Saron, Master of Fate

C'Thun, the Shattered

 The Warlock is truly the one closest to the Old Gods!

I really think this will be a slow but strong card.

Markmckz approves

This is op on wild wtf? 3 mana 9/9 voidlords? 4 mana 6/6 reno... plus you can play the card that organizes the deck by the cost to make this card give you tempo+ Win conditions.

When does Warlock in Wild ever spend mana to summon a voidlord?  I've never seen it.
