This will let you play a 4/4 [card]Foul Egg[/card] for 0 mana, won't it? I'm not sure if this will be better for playing low-cost minions for free with a buff, or high-cost minions for cheap where the deathrattle is …

This is going to take a hell of a lot to fully get rid of. Still, each minion summoned is only 1/1, so you'd probably want to have buffs handy next turn. [card]21152[/card] on turn 2 seems like a nice …

Will this be the card that make Deathrattle Rogue great, or does Rogue need more deathrattle minions or something? Lot's of neutrals, so I'm not sure why they wouldn't work.

More Thief Priest support. Seems to be quite a lot of that, but I'm not aware of it being a very strong archetype, so I guess it needs more?

This shouldn't be hard to play for cheap. Especially with [card]Underking[/card], which has a very good shot at making this free by itself.

Even single concoctions look reasonable at 3 mana, so playing a mixture of two, or all three for nothing? Sweet!

Well, this should be really good in a Big Shaman deck or anything that uses mostly expensive minions.

I'm going to guess they're printing more outcast cards, since you would want to play a lot if you are running this card, and we've only seen two DH cards so far.

Oh hey, [card]Deathstalker Rexxar[/card]'s hero power on a minion, so that, barring copying, you can use it a maximum of twice, and it isn't available at all times. And I have no idea if Rexxar is even any good today. …

I guess this doesn't do a whole lot when played, but I doubt many can complain about an additional 3/3 for free.

Given that this only gives one concoction per turn, I think you have a much less chance of getting a Mixed Concoction with all three effects than with [card]Potionmaster Putricide[/card], but then, this is an epic, while the other is …

12 armor plus a 6/6 rush for 7 mana can't possibly be bad, can it? You might even get all 12 armor the same turn if there's a big enough guy to trade this into. 

Looks like a pretty good defensive card, but the attack seems pretty low, so I'm not completely sure how strong this will be. The deathrattle combined with its lifesteal, along with the fact it has reborn, so it might do …

Looking at Neutral/Warlock deathrattle minions that might die before this does, nothing really stands out for this to gain. Maybe [card]Banshee[/card], or possibly [card]Foul Egg[/card]?

I assume that the text of Mixed Concoction changes based on what other concoctions you get. If you get all three, that's a lot for 3 mana, and in the right deck, it will be extremely easy to kill three …

Wording seems awkward, which minion? I didn't watch any of the streams, do they mean "Destroy a friendly Undead and gain its Attack."?

Well, I'm commenting now, and not when we know what this Vision of Darkness is. I guess permanently means it stays in you hand and can't be discarded or played. It better be good to limit your hand space to …

I imagine this most likely isn't staying alive more than one turn, but damaging the enemy hero and healing yours for 6 should be pretty good if you can use the healing. It's a source of even more healing if …

I'm pretty sure a 3-cost 2/5 taunt is good regardless, but summoning it for free off of something like [card]Scourge Supplies[/card]? Nice.

3-mana draw 2 basically, except you lose a card forever. Feels like a worse [card]11369[/card], unless you draw something that benefits from being discarded.
