"What do you get when you cast Thoughtsteal on an Orc? Nothing!" - Tauren joke
How to get
|Card packs||Regular, Golden||1~2|
- Thoughtsteal copies two cards from your opponent's undrawn deck; it will not copy cards which have already been drawn. Your opponent is not able to see which two cards you get from their deck.
- Thoughtsteal will not provide multiple copies of a single card in the opponent's deck, although it may copy two separate copies of the same card. This means that if there is only one copy of a certain card in your opponent's deck, a single Thoughtsteal will provide at most one copy of that card. However, a subsequent Thoughtsteal may copy the same cards again.
- Stolen cards can be used regardless of class. This allows the priest, a non-weapon class, to wield weapons.
- If the opponent has exhausted their deck, Thoughtsteal will not produce any cards, although it will still activate (which can make it useful for triggering effects such as ). If the opponent only has 1 card remaining in their deck (or only multiple copies of a given card), Thoughtsteal will provide a single copy of the remaining card. If the priest has 9 cards in their hand after playing Thoughtsteal, only 1 card will be copied, filling out the priest's hand. Additional copies will not be made and then destroyed; the spell will simply produce fewer copies.
- As with many generate effects, cards generated by Thoughtsteal are marked as such when being played, and when viewed in the history. This allows players to tell which cards the opponent copied, and thus know when they have played all copies.
Thoughtsteal is unusual in that it allows you to draw cards from your opponent's deck. This can be useful strategically; the cards drawn can be used to deduce the style and content of the deck, and any card which is drawn by the priest is shown to currently be in their opponent's deck and not in their hand. On the other hand, this card gives you randomly selected cards from another player and class's deck. This can result in drawing cards that have little synergy with your own deck, or even little or no actual use, such as drawing (unless you also steal a weapon card). However, playing Thoughtsteal does result in a net gain of one card, making it relatively efficient.
If a priest uses Thoughtsteal against you, you can use knowledge of the cards remaining in your own deck to deduce which cards they may have drawn.
One reason to include Thoughtsteal in a deck is simply to enjoy the unpredictable variety of drawing cards from another class mid-game. This can add an enjoyable element of RNG to the game, and defeating a player using their own stolen cards can be particularly entertaining.
If you use a golden Thoughtsteal, the cards you copy will become golden even if they are plain in your opponent's deck. This has no benefit to you when using them, other than aesthetic appeal. However, if you use a non-golden Thoughtsteal, the "goldenness" of the copied cards will follow the "goldenness" of the original cards. This may give you a tiny advantage. For example, if you copied a golden , then witness your opponent playing a non-golden one, they must be running 2 copies of that card in his deck, one golden and one plain. For this reason, top players do not mix golden/plain copies of any card in their decks; they either run both copies golden, or both plain. In this case, plain Thoughtsteals ofter a genuine (if slight) strategic advantage over golden ones.
While Thoughtsteal does not appear in Warcraft lore, it is similar to the Spellsteal mage spell from World of Warcraft in that it allows you to 'steal' spells from your opponent and use them as your own.
- During alpha, this card had the flavor text "That awkward moment when you steal his thoughts and realize he's thinking about you without pants on..."
- During alpha, Thoughtsteal used to actually steal cards from your opponent's deck. However, this was found to cause too much "emotional negativity", especially when stealing key cards from highly structured decks, and was changed to instead generate copies of the cards. This was an early example of Hearthstone embracing the possibilities of the digital medium, something which would not have been possible as a physical card game.
- The artwork for this card comes from the World of Warcraft Trading Card Game "Drums of War" series, for the card Lose Control.
