I will be continuing to update this post as more cards are revealed!

Death Knight Hero Cards

The big feature of the new expansion will be the Death Knight Hero cards. You’ll be able to transform your Hero into a Death Knight that has a new Hero Power for you to use!

  • Death Knight Hero cards are a new card type called Hero. They will not interact with things like Mirror Entity or Counterspell. [Source]
  • The Hero card replaces your current Hero, so if you are a Anduin you would become Rexxar if you played Deathstalker Rexxar. [Source]
  • If you are a different Hero Skin you would still become the hero of the card you played. Khadgar would be replaced with Death Knight Jaina. [Source]
  • Unlike Quest cards, Hero cards WILL be available in Arena. [Source]
  • Lord Jaraxxus will NOT be re-branded as a Hero Card. Jaraxxus is slightly different in that he sets your Health. [Source]
  • Hero cards do not replace your health, but do give you five armor when played. [Source]
  • Death Knight Heroes have new Emotes! [Source]

Lifesteal Mechanic

Lifesteal is the new keyword/mechanic coming to Knights of the Frozen Throne. When a card with Lifesteal deals damage, your Hero is healed for the same amount.

Deathstalker Rexxar

When playing Deathstalker Rexxar you receive the new Hero Power: Build-a-Beast. When used you will discover two beasts and combine them together to create a new beast with all the stats of both creatures sewn together: mana cost, attack, health, and card text. The card is then added to your hand.

  • When building a Beast you will not be given a choice of Beast that costs more than 5 mana (because the mana cost would be above 10 and mostly unplayable). No Savannah Highmane combinations unfortunately! [Source]
  • The first card you get to choose from are cards with text, and the second is cards with Keywords or are Vanilla (no text)! [Source]
  • The odds of receiving a Hunter or Neutral Beast card to choose from are equal. [Source]

Watch Deathstalker Rexxar in Action


Defile is seeing a lot of attention because the effect is unique and has far reaching consequences. The card is causing a nerf to the beloved Wild card: Dreadsteed.

  • Dreadsteed is being nerfed to: “Deathrattle: At the end of your turn, summon a Dreadsteed.”
    • You WILL receive a full dust refund for Dreadsteed once Knights of the Frozen Throne is released. [Source]
  • Grim Patron isn’t technically receiving a nerf, but there’s a hard cap on how many activations it will have so it will not go infinite. [Source]


Fatespinner contains a unique mechanic that allows you to secretly make your choose one choice. Your opponent will not know which you’ve decided to choose.

  • The +2/+2 will buff your opponent’s minions as well!
  • If you have Fandral Staghelm on the board the +2/+2 buff will trigger first and then the AOE damage. [Source]


Hadronox is similar to N'Zoth, The Corruptor but with Taunt minions instead of Deathrattles.

Prince Taldaram

Spreading Plague

  • The Scarab token will Cost 2 Mana. [Source]
  • The tokens are called “Scarab Beetle”. [Source]

    Referring to the cards that says, “If X happens, cast this again” is there a cap on how many times it will recast itself or until the condition is no longer met. Like with Defile, it can keep recasting itself until the board is clear if the condition that a minion dies every time it true?

      Yes, it can (and will) keep recasting until the board is clear as long as at least one minion dies with each cast.

    So i am curious, if you swap your hero with Jaraxxus and than proceed to play a hero card would you be able to keep the weapon Jaraxxus equips? I would think so but i haven’t seen a case such as someone transforming into Jaraxxus and than Ragnaros in the same match so im curious.

      I’m pretty sure you’d keep the weapon, but not the Hero Power.

    So I paid money not to play as Rexxar and Garrosh so I can play as zombie Rexxar and Garrosh. Awesome.

  5. Need DK's as a Class

    The problem I’m seeing with the new DK transformation card, is we get cucked out of a Deathknight class, even though its “Kinda” a deathknight template, in a little while when the standard cards change and you can no longer use cards from the LK expansion, we no longer get to use the Deathknight Transformation Card! =(
    So the game carries on, and people who like Deathknights get cucked and can never play that card/class again unless we go to Wild.
    Seems scuffed to me.

    • stop using words

      We get it, you learned a new word, but seriously stop using the word “cuck” unironically. You’re not being cuckolded. You’re really not.

    Hey Evident,

    If I open Deathstalker Rexxar in the first 10 packs of the next set, and then go defeat the Lich King, is it possible for me to receive a second Deathstalker as the reward? I know you probably don’t know the answer to this question, but it should be something keep in mind.

    Have a great day!

      Hey, yeah I’m not sure but it’s a good question!

        With the recent update of nomore copies of legendary cards, I would think not.

          I thought they said that it applies to packs. I hope that it also applies to other rewards.

    “The Hero card replaces your current Hero, so if you are a Priest you would become a Hunter if you played Deathstalker Rexxar.”

    This is a bit misleading, isn’t it? Deathstalker Rexxar is a Hunter card (it’s green), so you can’t play it while playing Priest.

    I was hyped by the thought that you can become another class.. but I think you are wrong here.

      you can if the card is stolen, or found through a discover mechanic
