Deathrattle: Put a Secret from your deck into the battlefield.

His mother wanted him to be a mage or a warlock, but noooooooo, he had to go and be a scientist like his father.

See this card on Hearthpwn

Mad Scientist is a common Naxxramas minion card.

How to get[edit]

Regular Mad Scientist is obtained by defeating Grobbulus in Curse of Naxxramas's Construct Quarter. Regular Mad Scientist is soulbound and cannot be crafted or disenchanted.

Once the regular version has been obtained, the golden version can be crafted:

Card Crafting cost Disenchanting
Golden Mad Scientist 400 50


Mad Scientist's Deathrattle will place a random Secret from your unused deck into play, removing the card from your deck.[1] However, it will not choose a Secret that you currently already have active, as it is not possible to have multiples of the same Secret activate at any time.[2]

  • If there are no Secrets remaining in your deck, or all remaining Secrets are copies of those already active, the Mad Scientist will not place any new Secret into play.[3]
  • The drawn Secret is not directly revealed to the controlling player, but can be checked by mousing over the Secret icon on the hero's portrait. The Secret is not revealed to the opponent.
  • A secret put into play by Mad Scientist's Deathrattle after it has been killed by a minion's Battlecry (or Combo / Choose One effect), WILL trigger from the summoning of that minion. For example, if a rogue uses an SI:7 Agent to kill a Mad Scientist, whose Deathrattle puts Mirror Entity into play, then the Mirror Entity will copy the SI:7 Agent. This is due to the specific order that Battlecries, resultant Deathrattles, and summoning-triggered effects resolve; for more information see the Advanced rulebook.


No draw[edit]

The behaviour of this minion's Deathrattle means that should it fail to put a Secret into play, the controlling player therefore has either already drawn all of their remaining Secrets, or has only copies of existing Secrets left in their deck:

  • If the controlling player has no active Secrets, this means they have no Secrets remaining in their deck.
  • In Play mode, if the controlling player has Secrets active, this means they have up to 1 copy of each active Secret remaining in their deck. However, in Arena the number of remaining Secrets could of course be higher, due to decks potentially including more than 2 copies of a given card.
    • For example, if a player in Play mode with 2 active Secrets fails to draw a Secret from the Mad Scientist's Deathrattle, they have between 0 and 2 Secrets remaining in their deck.
  • Any Secrets left in the deck must also be copies of existing Secrets, allowing the player to discount other possibilities. Once any active Secrets have been revealed, the player can be certain of the identity of any Secrets remaining in the deck.
  • Note that this only indicates the contents of the player's deck - they may have Secrets left in their hand. Once the contents of the deck have been surmised, the maximum number of additional Secrets remaining can be learned from the size of the player's hand.
    • Careful counting of the cards in the player's hand can reveal whether any of those cards were Secrets, further consolidating the knowledge gained.

For example, if a player in Ranked play with 0 active secrets fails to gain a Secret from the Mad Scientist's Deathrattle, they have no Secrets left in their deck. If they have cards currently in their hand, the opponent can watch the position of those cards, and once they have all been played, can be sure the player has no other Secrets remaining this match.


This card appears to depict a Forsaken apothecary. While their expertise is primarily alchemical, apothecaries dabble in a range of dark sciences.

From Wowpedia:

When people think of witch doctors, they usually don’t think of Forsaken. However, Forsaken are some of the most skilled alchemists on Azeroth, and while they don’t entreat voodoo spirits for help and don’t call their craft “mojo,” they still possess tricks to make their brews especially potent. These Forsaken call themselves apothecaries.
The iconic apothecary is a withered Forsaken standing in a laboratory. Beakers and cauldrons bubble and spew horrible vapors into the air.

The art itself strongly resembles Apothecary Frye.


I'll show them! I'll show them all!
For Science!
