Previous availability[]


  • This card's effect creates a cost-modification enchantment attached to your player: this means that it will not be cancelled if your hero is replaced by Ragnaros or Lord Jaraxxus. This enchantment reduces by 2 the mana cost of spell cards in your hand, but wears off as soon as you play a spell or at the end of your turn (whichever happens first).


Preparation is one of the best Combo activators for Rogues, disregarding the state of the board unlike Backstab or Shadowstep on top of providing a mana discount for chaining more Combo cards. As a free spell used in combination with other spells, it is excellent for use with cards such as Violet Teacher and Gadgetzan Auctioneer, and in such decks is best saved for when one of these minions is on the board.

Preparation is also useful for making expensive spells much more accessible. Cards like Sprint or Vanish can be used without consuming all of your mana.

Fixed bugs[]

  • Until Patch (WotOG patch), Preparation attached an enchantment to your hero, meaning that if you replaced your hero (such as by playing Lord Jaraxxus) the enchantment will be removed and lost. However, the enchantment can not be removed through Silences, such as by using Light's Champion on the Lord Jaraxxus hero, because it is explicitly set to be unsilenceable.[1] (As of Patch (LoE patch), Light's Champion can no longer target the Lord Jaraxxus hero.)
  • If you played Preparation, Summoning Stone then played a spell, you paid the Preparation-discounted cost but Summoning Stone summoned a minion according to the undiscounted cost. (Gazlowe also used the undiscounted cost to decide whether to trigger or not.)[2] This bug was fixed in Patch (WotOG patch).
  • Starting in Patch (LoE patch), if you played Preparation then a spell with Overload, you did not gain any Overload. In addition, Unbound Elementals would trigger as normal, but Tunnel Troggs would gain Attack only if played BEFORE the Preparation was.[3] This bug was fixed in Patch (2015-12-04).

Patch changes[]

All changes we make to the Basic and Classic sets are aimed at ensuring Hearthstone's long-term health. Preparation is currently seen as such a powerful card that it appears in nearly all Rogue deck archetypes. That said, the change we've landed on is a small one. While we do want the card’s power to decrease, we also think it's important for Preparation to remain a reasonable option, since it fits the Rogue class fantasy so well.
Preparation is regularly used to reduce the cost of cards like Sap or Eviscerate, and those interactions will remain unchanged. Reducing the cost of your next spell by 2 as opposed to 3 opens our design options up a little more to create higher cost Rogue spells without having to balance so closely around the assumption that they'll be cast alongside Preparation.
  • Patch (2013-10-02): Now reads: ...costs (3) less. (previously: ...costs (2) less.).
    • Previously: The next spell you cast this turn costs (2) less. [0 mana, Epic][4]
