Strategy
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).
Notes
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. 
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 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.
- Mad Scientist`s put into battlefield Put into battlefield effects are abilities which puts cards from the player s deck or hand directly into the battlefield. They may affect minions or spells, and may require a specific type or sub-type of card.
effect will not activate triggered effects The lightning bolt icon, explicitly indicating a triggered effect Triggered effects are effects that activate in response to specific events. Triggered effects may belong to minions, weapons or spells (in the form of Secrets), as which trigger from Secrets being `played` or `cast`, such as Mana Wyrm Mana Wyrm Set: Classic Type: Minion Class: Mage Rarity: Common Cost: 1 Attack: 1 Health: 3 Tags: Spell-related, Triggered effect Whenever you cast a spell, gain +1 Attack.These wyrms feed on arcane energies, and while , Secretkeeper Secretkeeper Set: Classic Type: Minion Rarity: Rare Cost: 1 Attack: 1 Health: 2 Tags: Secret-related, Triggered effect Whenever a Secret is played, gain +1/+1.She promises not to tell anyone about that thing you did last or Fel Reaver Fel Reaver Set: Goblins vs Gnomes Type: Minion Subtype: Mech Rarity: Epic Cost: 5 Attack: 8 Health: 8 Abilities: Remove from deck Tags: Triggered effect Whenever your opponent plays a card, remove the top 3 .
- A secret like Mirror Entity Mirror Entity Set: Classic Type: Spell Class: Mage Rarity: Common Cost: 3 Abilities: Copy, Secret, Summon Tags: Summoning-related, Triggered effect Secret: After your opponent plays a minion, summon a copy of it."You go first." - 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 in the subsequent After Play Phase and affect the played minion. For instance, if a rogue uses an SI:7 Agent to kill a Mad Scientist, whose Deathrattle puts Mirror Entity Mirror Entity Set: Classic Type: Spell Class: Mage Rarity: Common Cost: 3 Abilities: Copy, Secret, Summon Tags: Summoning-related, Triggered effect Secret: After your opponent plays a minion, summon a copy of it."You go first." - into play, then the Mirror Entity will copy the SI:7 Agent. This is due to the specific order that Battlecries, deaths/on-death triggers and After Play Phase triggers resolve. for more information see the Advanced rulebook. It seems that for now (as of Patch 5.0.0.12574 (WotOG patch)), the behaviour is intended.
- If a Mad Scientist`s Deathrattle puts into play a secret which triggers from death (e.g., Duplicate Duplicate Set: Naxxramas Type: Spell Class: Mage Rarity: Common Cost: 3 Abilities: Copy, Generate, Secret Tags: Death-related, Triggered effect Secret: When a friendly minion dies, put 2 copies of it into your hand.The one time , Redemption Redemption Set: Classic Type: Spell Class: Paladin Rarity: Common Cost: 1 Abilities: Copy, Secret, Summon Tags: Death-related, Resurrection effect, Triggered effect Secret: When a friendly minion dies, return it to life with 1 Health.I am or Avenge Avenge Set: Naxxramas Type: Spell Class: Paladin Rarity: Common Cost: 1 Abilities: Secret Tags: Death-related, Random, Triggered effect Secret: When one of your minions dies, give a random friendly minion +3/+2.Several paladins have joined together ), the secret will not trigger on the Scientist`s Death Event. This is because when we start resolving a Death Event (like the Mad Scientist`s Death Event), we queue all related on-death triggers then resolve them. An on-death trigger that becomes eligible after this queue is populated is too late to join it.
- If a Mad Scientist dies at the same moment as another minion, which entered play after the Scientist, and the Scientist puts into play a secret which triggers from minion death (e.g., Duplicate Duplicate Set: Naxxramas Type: Spell Class: Mage Rarity: Common Cost: 3 Abilities: Copy, Generate, Secret Tags: Death-related, Triggered effect Secret: When a friendly minion dies, put 2 copies of it into your hand.The one time or Redemption Redemption Set: Classic Type: Spell Class: Paladin Rarity: Common Cost: 1 Abilities: Copy, Secret, Summon Tags: Death-related, Resurrection effect, Triggered effect Secret: When a friendly minion dies, return it to life with 1 Health.I am ) the secret will not trigger from the Scientist`s death, but will trigger from the next minion`s death. This is because Death Events are resolved in play order, and each one queues all on-death triggers that are eligible when it begins to resolve. (This means that Mad Scientist pulling an on-death Secret can`t have it trigger on a minion played before the Scientist or on itself.)
- 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:
- If the controlling player has no active Secrets, this means they have no Secrets remaining in their deck.
- In Play mode Preparing for battle in Ranked play mode, in Standard format Play mode is a game mode that matches players against other human players of similar skill. Players can choose to play Casual friendly games, or , if the controlling player has Secrets active, this means they have up to 1 copy of each active Secret remaining in their deck. Be that as it may, in Arena A video explaining the Arena in Hearthstone made by the Curse Gamepedia @@@#@@@YouTube(youtube.com)###@### Channel. The Arena is a game mode where players compete against each other using specially constructed decks to earn substantial rewards. It the number of remaining Secrets could of course be higher, due to decks potentially including more than 2 copies of a given card.
- For instance, 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 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.
