I think it's still probably going to be ok in token decks that can take advantage of the beast tag, like fast hunter or druid decks, since a 0 mana 2/5 beast is not bad. Probably gone in rogue though, and is no longer broken enough to just put 2 in every deck in the game.

Hmm, lack of creeper means decks might be able to get a bit greedier, but I don't see patches going anywhere, aggro decks will survive. Cubelocke is going to be amazing, but control warlock is definitely beatable with other control decks in my experience. I'm more worried about jade popping up again as a t1 deck, I'm guessing control warlock will need to run geist or cube combo to beat it. 

Big spell mage could make a resurgence as well, it doesn't get nerfed at all, it's matchup against warlock doesn't feel that bad (cubelock is tough but control is pretty even), and its matchup against aggro is very draw dependent. It was held down by raza, specifically otk or near otk Gaza comboes. Velen/hp/mind blast/hero power is only 18 damage now, which makes otk way tougher for this deck. If warloc can counter jade, other slower decks might just make it work.

This is only in decks because it's pretty much the only answer right now for warlock in classes that lack hard silence removal like polymorph or hex. Its pretty weak if it's not an answer card, its power level is determined by the opness of the deck you're facing, so I don't think it will be removed anytime soon.

Reflecting what many others have said here, voidlord is not that strong on its own, without a deck built around it its only a little stronger than sleepy Dragon and giant Mastodon.

However, possessed lackey can get it out turn 6, it can be brought back by bloodreaver guldan and nzoth, it's a safe target to cube because its deathrattle means you aren't vulnerable when you cube it, and warlock has cool things it can do in a long game, like cube/doomguard, rin, guldan, and nzoth. Warlock also has a bunch of healing it didn't used to have.

Its really a combination of a bunch of different factors that make this card good. I actually like it though. Playing frost lich jaina against control warlock is some of the most fun I've had in this game in a while.

I've been trying it recently with deck of wonders. Aluneth activates at the end of your turn, which means it can somewhat reliably make a late game deck of wonders become "cast three to five random spells with random targets immediately"

It's like a budget yogg that usually makes you lose to fatigue, but is tremendous fun to play.

Reflecting what others have said, creeper is probably a safe craft because you can pretty much put it in any deck and have it be a good card. Spiteful summoner is really powerful, but only if you want to play a deck around it, craft it if you want to play a hyperexpensive spell deck, otherwise it's not worth it.

The more I think about it, the more I actually like this card. A 9 mana 2/4 is bad... Except the effect is actually amazing. If this gets out an 8/8 or a 12/12, your opponent needs to kill two minions immediately or lose the game. Priest would need something like psychic scream or shadow word death and a shadow word pain, hard to do at turn 9. Mage needs a meteor and a ping, or a doomsayer/frost nova, but if you deal with the doomsayer you've basically won.

Even if you get out a primordial drake, that's a taunt which might protect your dragoncatcher. Point is, this is a must remove immediately card that can call out another must remove immediately card. That could have some hidden value.

Seems insane to me. 4 mana 4/4 is good enough it won't lose you the game when you play it, and rogue has insane card draw already with auctioneer. One of the best cards of the set so far.

I'm a bit more optimistic about this card than most, though it's going to be bad in a weapons heavy meta. Tortallan primalist is... Well, it's not good in constructed, but actually pretty decent in arena, because discovering a spell and casting it is really good, even with random targets. If you can get 3 spells off of this weapon, I think it pays for itself.

The issue is the massive loss of tempo if you whiff on the first spell, and the probable prevalence of weapon removal in this meta. If Harrison jones becomes common, this card is awful, but if there's some weird state where nobody plays weapons or removal because of an overreaction to weapon removal early in the meta, this card could be pretty good.

At first I thought this was a bad card, then I realized, the biggest issue with terrorscale stalker was it's inconsistency. This could be run alongside terrorscale and a bunch of deathrattles, and it probably would just made the deck way more consistent.

Maybe not the best deck, but if you run enough cards with the same effect, that means it's easier to build your deck around it.

So, this is a bit overreactionary. This card makes it hard to win with 1 cost spells that are endgame combos. This does not make all 1 cost spells useless. It may actually help control warrior, would you rather draw a whirlwind or a direhorn matriarch on turn 12 in taunt warrior? Power word shield is good because it is a passthrough with a small benefit, it isn't a huge deal to get it removed from your deck.

Inner fire and jade idol are hurt the most, because those cards are victory condition activators. Maybe evolve too, but with the shaman death knight, that's not a huge deal. Otherwise, it can be a small buff or nerf to decks, but this really encourages faster playing of one cost spells more than anything.

It will play out sorta like golaka crawler and eater of secrets I think. It will be a tech option and keep jades in check, but eventually it will reach an equilibrium where its run enough that it will discourage jades, but not enough to shut down the deck completely. Running a 4/6 6 drop that doesn't alter the board at all in a deck that already has a lot of high drops leaves you pretty vulnerable to aggro with a bad draw, and I think control decks will notice that pretty quickly.

It will still be meta defining because jades hard counter a lot of the super control styles that have been pushed in this expansion, but questionable card design nonwithstanding, I think it will leave the meta in a better place.

one issue with this is that playing all your secrets at once removes the secret element to it. If there haven't been two counterspells played yet this game, and I see this planted, I know my next spell should be low cost one. If there haven't been two mirror images, I'm playing a weaker minion next, which could theoretically trigger both potion of polymorph and mirror image. Its a very powerful block if you need a turn and want to thin your deck, but half the value from secrets comes from the awkwardness your opponent has to experience from not knowing what they are (like, playing a weak minion in to counterspell, or a weak spell in to mirror image). Here you will know what they are. It also has negative synnergy with arcaneologist unless you really need a lot of card draw quickly, like if you're doing quest mage.

Still, 'draw and play 4 cards from your deck' is a pretty good card regardless.

At first glance my reaction was, "huh? A yeti that makes your hand worse? Why?"

Then after reading the comments and thinking about it, well, a lot of rogue spells are pretty weak for low mana cost, and rogue can generate low cost spells pretty effectively. Early game this could curve in to etherial peddler to get a bunch of cheap spells that are better than your initial cheap spells, or later in the game you can change cheap spells in to more expensive, better spells.

I'm curious to see if people can make this work, there's some potential here, but its hard to tell if this will actually be good.

 This looks insane, considering you can play your cheap minions to make this copy your expensive ones. Its pretty easy to manipulate your hand so that only 6+ cost minions are left in it by the time you play it. This isn't an on curve play usually, but I think even outside of a combo deck it will get pretty good value.

In a combo deck this just gets ridiculous. This will be meta defining in my opinion.

EDIT: Actually, I may have misunderstood it. I thought the card would be put in play. If its only put in your hand its pretty niche, though could have its uses in a spell heavy deck.
