Mad Scientist is a very strong choice for any secret- or Deathrattle-oriented deck. 2 copies are commonly used even with as few as 3 secrets in the deck, especially for decks focusing upon the early to mid game.

Should the player remove all secrets from their deck before the Mad Scientist`s Deathrattle can trigger, the Mad Scientist`s value can quickly evaporate. This is particularly important for decks with low numbers of secrets. Despite this, as long as there are sufficient secrets in the deck to provide a good statistical chance of the Mad Scientist putting on into play, the minion can be considered a solid choice.

The threat of the secret put into play by the Mad Scientist can also be effective in affecting the opponent`s plays, even if the player lacks the secret. Be that as it may, be aware that a Mad Scientist that does not put a secret into play may provide the opponent with information regarding your remaining deck (see below).


Mad Scientist`s Deathrattle A Loot Hoarder displaying the Deathrattle icon Deathrattle is an ability where the stated effect occurs when the minion or weapon is destroyed. Cards with Deathrattle appear with a skull and crossbones when in play. hearthstone will place a random Secret A Secret is a spell card that is cast normally but has a delayed, hidden effect, which only takes place when a specific event occurs. When a Secret is played, a Secret icon appears on hearthstone from your unused deck into play, removing the card from your deck. Be that as it may, 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.

  • 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.
  • 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.
  • When a Secret triggers, it immediately leaves play, meaning that a Mad Scientist Deathrattle can immediately put another copy of that Secret into play. This can allow you to resolve two Avenges in the same Death Phase, for example.

Known bugs

As of Jan. 2015, a known bug allows Mad Scientist`s Deathrattle to cause the player to exceed the 5 secret limit. Mad Scientist still will not act upon duplicates of currently active secrets, but will put additional different secrets into play if available in the player`s deck, essentially ignoring the 5 secret limit. This has been shown to allow at least 11 different secrets to be active on a hero at the same time. Secrets beyond the 5 limit will activate and take effect normally, and in the correct order.

No draw

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:

For instance, 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.
