Curious Glimmerroot

Curious Glimmerroot is an epic priest minion card, from the Journey to Un'Goro set.

Strategy
This card requires knowledge and possibly some luck to make use of. Using this card requires the player to know the current meta in order to determine what card your opponent is most likely to put in their deck. Because of this, this card can be "soft-countered" by non-traditional deck building, as using unusual cards like Renounce Darkness, or Shatter can throw a player off.

Because Curious Glimmerroot prioritizes class cards, the combination of both the 3/3 body and the card received is generally of greater value than what is received through Thoughtsteal. This prioritization of class cards also makes choosing the correct card considerably more reliable than what the card texts would suggest as most of the unpredictable cards in common decks (such as tech cards) are neutral.

Cards which synergize with Curious Glimmerroot are those that have the ability to reveal cards in the opponent's deck, such as Thoughtsteal, Drakonid Operative, Crystalline Oracle, Shifting Shade, and cards with Joust.

Obviously, the later in the game this card is used, the higher the chance that the card from your opponent's deck has already been played, making it a no-brainer to see which card started in your opponent's deck.

When you pick the "wrong" card, even though you do not gain a card, you do gain knowledge of your opponent's deck: you now know for sure one card that is, and two cards that are not in their deck.

Lore
Glimmerroot is original to Hearthstone, as both a herb and sentient plant.

Trivia

 * Curious Glimmerroot was originally an idea for a Rogue legendary, but ended up going to Priest as an epic.
 * This card's flavor text is a reference to the children's book character.

Known bugs

 * If Curious Glimmerroot discovers a Molten Blade from the opponent's deck which has already transformed into a weapon, then it will show you the weapon it transformed into, instead of the Molten Blade that actually started in your opponent's deck. In this case, if the transformed weapon is not from the opponent's starting class, Curious Glimmerroot will present Discover options which are of the class of the new weapon. This bug will be fixed in the near future.
 * Curious Glimmerroot's Battlecry does not trigger in the ShiftCon Tavern Brawl.
