My Rating System


Each card is rated on a scale of 1 to 5 on two criteria: Power and Versatility.

The Power rating reflects how much I expect a card to impact the game when played. Cards which immediately represent multiple cards worth of value (Ultimate Infestation) or have a powerful effect on the board for their mana cost (Sunkeeper Tarim) will receive high Power ratings, while cards which have a low impact on the game (Ice Breaker) or cost too much for their effect (Furnacefire Colossus) will receive Power low ratings.

The Versatility rating is intended to communicate how dependent a card is on other cards for its success. Cards can be very powerful without being versatile at all (Clutchmother Zavas), which means that many exciting and powerful cards will end up seeing very little play once the metagame is established. A high Versatility rating means a card relies very little on other cards to be good, and the more comfortable I would feel crafting that card on day one. A lower Versatility rating doesn't necessarily reflect that I expect the card to be bad, but that I wouldn't feel comfortable crafting it until it has proven itself to be a part of a competitive deck.

Kobold Librarian


Fits into: Everything?

Power Versatility
4 5

A one mana 2/1 that Life Taps for free? I'll take two, please!

If this guy ever manages to trade for an enemy minion then you got yourself a two-for-one for only one mana! This is exactly the kind of card that aggressive Warlock decks would love to play, but I think it's strong enough to see play in midrange and controlling Warlock lists as well. I expect to see this little guy everywhere in the new meta.

Vulgar Homunculus


Fits into: Demonlock, Handlock, Zoolock?

Power Versatility
4 4

If it weren't for Prince Keleseth, this little Demon would also be joining Kobold Librarian in almost every new Warlock deck. It's great on defense, it's great on offense, and it has the incredibly important Demon minion-type to provide Bloodreaver Gul'dan with another Taunt minion for his Battlecry trigger.

Though two damage to your hero will likely mean one fewer Life Tap for controlling decks that need to concerned about their life total, the Battlecry on Vulgar Homunculus won't always be a downside. We're going to see several new Warlock cards very soon which benefit from inflicting self-damage, positioning Vulgar Homunculus as an important role-player in a brand new archetype.

Dark Pact


Fits into: Sacrifice, Control Warlock

Power Versatility
2 2

If you need Dark Pact, I think you'll know it. Sacrifice decks in need of extra ways to kill their own minions might want to run a few copies of this card, as well as slower Warlock decks in desperate need of ways to pad their life total.

Amethyst Spellstone



Fits into: Slower decks with 4 or more self-damage cards

Power Versatility
3 2

I don't think this card is strong enough to works its way into decks which can't reliably trigger the upgrade clause. Fortunately for Amethyst Spellstone, I expect almost everything to be running Kobold Librarian and Vulgar Homunculus. The Lesser version isn't terrible, but I think you'll really want to be playing this as its Normal or Greater version to feel as though Amethyst Spellstone is pulling its weight. I don't think this is efficient enough for aggro decks, but predict that Handlock will be more than happy to run a couple copies of this.

Possessed Lackey


Fits into: Don't play this card

Power Versatility
1 1

Too expensive, too slow, and probably not consistent enough at finding Voidlord to warrant a spot in normal Demon decks. Pass.

Hooked Reaver


Fits into: Demonlock, Handlock, Self-damage decks

Power Versatility
4 4

A four mana 7/7 is quite the payoff for a self-damage themed deck! Memes aside, I'm really happy about the way this card was designed. Players are going to have to make quite a few interesting decisions with Hooked Reaver, as it won't always be obvious if this card should be played on turn 4 as a lowly 4/4 to buy tempo, or saved until it can be played for full value. Playable cards with relevant minion-types that lead to interesting decisions are exactly the kinds of cards I love to see in new Hearthstone sets.



Fits into: Slower decks with Bloodreaver Gul'dan

Power Versatility
4 3

A big, nasty Taunt minion with a huge butt is exactly what Handlock and other slow Bloodreaver Gul'dan decks were in the market for. Outside of Hex and Polymorph, it's going to a nightmare for the average deck to slog through the 18 Health of Taunt minions that this card generates. Aggressive decks are going to have to find a way to kill Warlocks before this card wreaks havoc on the battlefield.



Fits into: Handlock, Quest Warlock

Power Versatility
4 2

It'll be interesting to see if controlling Warlock decks use this as an "oops!" button for games that get out of hand early, or if they find that the downside on this card is too high and are satisfied with the number of board wipes they already have in Twisting Nether and DOOM!. Either way, the most exciting application for this card is a to dump your hand and quickly activate Lakkari Sacrifice. I'll admit that I have a really hard time predicting just how prevalent Cataclysm will be in the upcoming meta, but my instincts tell me that a 4 mana card that says "Destroy all minions" is probably good.

Rin, the First Disciple



Fits into: Grindy Warlock Decks

Power Versatility
2 2

How awesome it this card?! I doubt I'll ever end up crafting it, but if ever open it up in one my packs I have no doubt that I'll play Rinlock until I finally kill my opponent with an Azari, the Devourer.

This card is obviously incredibly cool and flavorful, but I don't think its very good. The 3/6 Taunt body is certainly relevant, but there can't that many matchups where you will have the time to play enough seals to make Rin a worthwhile investment. I see Rin as a trump card for grindy Control mirrors, and don't expect her to show in competitive decks unless the metagame becomes incredibly slow.

Skull of the Man'ari


Fits into: Demonlock

Power Versatility
2 1

Skull of the Man'ari is probably my least favorite of all the Legendary weapons. It doesn't do anything the turn it comes into play, and it comes with zero insurance against the Gluttonous Ooze type cards which will likely be in the majority of competitive lists. It doesn't even provide card advantage, just tempo. Getting to trigger this two or three times will make it worth your while, but I have my doubts that this is the best thing Demonlock decks can do with their mana on turn 5.

Thoughts on the Class

Warlock bounced back from Journey to Un'Goro in a big way during Knights of the Frozen Throne, but it was never quite able to break into top tier of classes. I expect that to change with K&C. Warlock is getting two excellent Commons, a game-changing Rare, and a pair of narrow but powerful Epics. The Legendaries aren't much to write home about, but Warlock fans will be happy to have picked up more playable cards from K&C than any other class.

I think you overrate the common by maybe 1 point in power but they are definitely strong.

I would give the Spell Stone 1 more power anyway my general issue with Spell Stones is if you draw them late you wish you would have put another card into your deck :D

And it's rough, both of the class legends are (probably) useless (Paladin looks similar). That's really disgusting.

One point I'd make is that Voidlord can "clutter" your gul'dan play by creating too many weak taunt minions when you finally play Gul'Dan, and muscling away your 6/6s, 4/5s and so on.

And I thought I'm the only one not being excited that much about Voidlord. I don't want a board of weaklings who get killed eventually and doing no damage :D

      We'll get to see 25 new cards in the first week of Witchwood spoilers.
      The full Witchwood card reveal schedule was announced today, detailing the art, names, and times of the 55 cards which will be spoiled over the next two weeks.
      The first week of Witchwood spoilers will brings us 25 cards.  Some of the community members spoiling cards include Thijs, Eurogamer, Alliestraza, Ddahyoni, and Omnislash:

      For two weeks, players will receive one card pack in addition to the normal reward for completing a Daily Quest.
      There are no sweeter words than "free packs" to a Hearthstone fan, which makes today's announcement of the New Year of the Raven Party as sweet as it gets. Beginning on March 26th and ending on April 9th, each Daily Quest completed during the New Year of the Raven Party will reward one card pack in addition to the normal rewards. These packs can be from Journey to Un'Goro, Knights of the Frozen Throne, Kobolds & Catacombs, or even The Witchwood (but they won't open-able until the set releases). That adds up to 14 free packs for daily Hearthstone players, and two additional packs to players who is wise enough to bank up a couple of Daily Quests coming into event.
      Blizzard held a similar event last year leading up to the release of Journey to Un'Goro, which rewarded dust, gold, packs, and even a golden Volcanosaur on the final day of the event. Even though there are already 14 reasons to be excited about the New Year of the Raven party, there could be even more free rewards in store for us as we approach the release of The Witchwood.

      Ben Brode answers sixteen minutes of fan questions in his latest video, shedding light on a number of fun and interesting topics.
      In collaboration with WIRED, Hearthstone's Game Director Ben Brode answered a number of questions from the Hearthstone community in a 16 minute video. The questions span a wide variety of topics, including game balance and new client features:
      Videos with Ben Brode are regularly entertaining to watch, and this one was no exception. It's probably worth a watch (perhaps on 1.25 times speed?) for most big-time Hearthstone fans. However, if you don't have 16 minutes, here's a quick summary of some of the questions which were covered in the video:
      Question: Have they considered ways to balance going second other than The Coin?
      Answer: Several things were tried in place of The Coin during initial design, including giving a 1/1 minion to the player who goes second or making the first minion they play get a 1/1 bonus to its stats. The goal was to aim for a 55% win percentage for the player who goes first, which is equivalent to Chess. The Coin not only achieved that targeted win percentage, but it created some cool moments and interesting decision points along the way.
      Question: What are the chances that cards will be added to the Classic set?
      Answer: High! The Hall of Fame has made it so that Mage has fewer cards than the other classes in Standard. Though they'd have to be very careful about it, there's a good chance that Mage could receive some new Classic cards in the future.
      Question: Why has the focus been on nerfing cards, a not buffing them?
      Answer: The objective is not to make all cards be of the same power level. They want bad cards to exist just as much as they want good cards to exist. Having bad cards can be a benefit to the game, such as with Paladin Secrets. The fact that Paladin Secrets were generally quite bad allowed them to create a card like Mysterious Challenger.
      Question: Will the upcoming tournament mode have a sideboard feature?
      Answer: No, and not likely to happen for a while. Tournament mode will have Conquest and Last Hero Standing modes to start, but it will pick up additional features over time.
      Question: What are the chances that Inspire gets a second look?
      Answer: Not in the near future, but it could happen eventually.
      Question: Will there be a way for players to get old card backs?
      Answer: Eventually, yes! They obviously can't just give them out for free, because that would feel bad to the players who worked hard to get them. They also couldn't make them too hard to get. But if they could find a method which struck a good balance between the two, then this is likely to happen.
      Question: Is Cubelock on their balance radar?
      Answer: Yes! They think it's a skill-testing deck. It posts strong winrates for players who have practice with the deck, but less-than-stellar winrates for players who are just picking it up. They are aware that many players don't like losing to this deck, and they want to collect more data on that. With set rotation coming up they are unlikely to make any changes to Cubelock in the near future, but if the deck is a problem after The Witchwood comes out then they will address it.
      Question: Have they thought about game modes with other deck sizes?
      Answer: They have tried out modes with other deck sizes, including a mode where the decks were 60 cards in size and could have no more than one of each card in it. They don't plan to add any modes like this in the future, but something like this would make a good Tavern Brawl.
      Question: Will there be more rewards for leveling up your Heroes in the future?
      Answer: They would like to add more content to the Hero leveling system in the future.
      Question: Why the unnerf to Molten Giant but not other cards?
      Answer: Molten Giant is a card with a huge following. Many players love the card, and the Hall of Fame was created in part so that cards like Molten Giant can live on in Wild. They are likely to do what they did with Molten Giant to other cards in the future.

      The "Enrage" keyword will be replaced by "while damaged" in an upcoming patch.
      Announced in today's Designer Insights with Peter Whalen, Hearthstone's "Enrage" keyword will be replaced by "While Damaged" in a future patch. Whalen noted that the reason for this change is clarity. Though Hearthstone keywords are typically meant to to be used as shorthand for more complicated effects, Enrage is only one word shorter is than "while damaged" and no less clear.
      You can see an example of the new card templating below:

      Though a date has not yet been provided for when these changes will take place, I'd be surprised if they were not made before The Witchwood is released in mid-April.
