Transmute is the keyword ability of cards in Ravnica block aligned with the Dimir guild. It works by allowing a player to pay the transmute cost of a given card, discarding the card, then searching his or her library for a card with the same converted mana cost as the discarded card. It appears only on Black and Blue cards.

Unlikely to return

R&D have soured on Tutoring mechanics as they make games play out too similarly. Individual tutors are considered to be fine, but they don’t currently plan to do whole mechanics like Transmute, anymore.

From the Comprehensive Rules (June 7, 2024—Modern Horizons 3)

• 702.53. Transmute
  • 702.53a Transmute is an activated ability that functions only while the card with transmute is in a player’s hand. “Transmute [cost]” means “[Cost], Discard this card: Search your library for a card with the same mana value as the discarded card, reveal that card, and put it into your hand. Then shuffle your library. Activate only as a sorcery.”
  • 702.53b Although the transmute ability can be activated only if the card is in a player’s hand, it continues to exist while the object is on the battlefield and in all other zones. Therefore objects with transmute will be affected by effects that depend on objects having one or more activated abilities.

Rulings

• If you transmute a card with mana cost , for example, you can search for any card in your library with converted mana cost 2. It doesn't matter what type or colors that card is.
• You don't need to have another card with the same converted mana cost in your library to play the transmute ability, and you don't need to find a card even if there is one.
