Transmute MTG: How It Works, All 14 Cards, What Each One Finds and a $62 Oona Deck (2026)

Transmute is the Magic: The Gathering keyword that turns a card in your hand into a tutor. You pay the transmute cost, discard the card, and search your library for a card with the same mana value. You can only do it at sorcery speed. Muddle the Mixture costs {U}{U}, so transmuting it finds any card in your deck with mana value 2: Isochron Scepter, Counterspell, Arcane Signet, whatever the game needs.

There are only 14 cards with transmute. Thirteen came in Ravnica: City of Guilds in 2005 as the Dimir guild’s mechanic, and Tolaria West followed in Future Sight in 2007. None has been printed since, and every transmute cost is exactly three mana. To see what the keyword is worth, we built a budget Oona, Queen of the Fae combo deck with 12 of them and ran it through 100,000 test games, then ran it again with transmute switched off. With transmute, the deck had found both halves of its combo by turn 10 in 64% of games. Without it: 19%.

This guide covers the transmute rules, how mana value works for the search, what each mana value finds, all 14 cards, the combos that share a mana value, legality in every format, how to beat it, and a $62 Oona Commander deck.

What is transmute in MTG?

Transmute is rule 702.53 of the Comprehensive Rules. Rule 702.53a says it is “an activated ability that functions only while the card with transmute is in a player’s hand”, and that “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.”

Four things follow from that sentence.

• It’s an ability, not a spell. You aren’t casting anything, so Counterspell and Negate can’t stop a transmute. Only effects that counter activated abilities can.
• Discarding is part of the cost. The card is in your graveyard before anyone can respond. If the ability is countered, you’ve still lost the card and the mana.
• The search is by mana value only. Colour, card type and name don’t matter. A blue instant can find a black creature, an artifact or a land, as long as the number matches.
• You reveal what you find. The table knows exactly which card went to your hand.

Every transmute card is also a normal card. Muddle the Mixture is a counterspell, Drift of Phantasms is a 0/5 flying blocker, Tolaria West is a land. You choose each time: play it for what it is, or pay three mana to trade it for the card you need more. That choice is why the mechanic is still played 21 years after it was printed.

Transmute rules: 14 common situations

Mana value is the whole mechanic

A transmute card is only as good as the best card in your deck that shares its number. That makes the mana value printed in the corner the most important thing on the card, and it explains why the cheap ones are played far more than the expensive ones. Here is what each one can find in Commander. The counts are Commander-legal cards on Scryfall on 11 November 2026; the targets are the most played cards at that number in blue, black and colourless.

Two rows stand out. Mana value 2 is where the mechanic lives: 6,871 nonland cards, including most of Commander’s mana rocks, its cheapest counterspells and both halves of several combos. That is why Muddle the Mixture is in more Commander decks than any other transmute card, and why three of the 14 cards share that slot.

Mana value 0 is the strangest. There are 1,300 Commander-legal cards with mana value 0, and all but 147 of them are lands. Tolaria West is a land that can become any other land in your deck: a Bojuka Bog when a graveyard gets out of hand, a Reliquary Tower when you’ve drawn 20 cards. It also finds every spell with no mana cost or a cost of {0}: Pact of Negation, Summoner’s Pact, Lotus Petal, Everflowing Chalice, and suspend cards such as Ancestral Vision. In Modern, Amulet Titan decks have used Tolaria West for years to fetch Summoner’s Pact, which then fetches Primeval Titan.

Does transmute work? Transmute on vs off

To put a number on it, we took the Oona deck at the bottom of this page and played 100,000 goldfish games with it, twice. In the first run the 12 transmute cards worked. In the second they did nothing. The deck’s main plan is the two-card combo of Isochron Scepter and Dramatic Reversal, both mana value 2. We counted how often the deck had found both cards, and how often the combo was live: Scepter on the battlefield with Reversal under it, and mana rocks that make three or more mana between them.

By turn 6 the deck with transmute had both pieces in 40% of games, against 10% without. By turn 10 it was 64% against 19%, and the combo was live in 37% of games against 10%. In the games where the combo came together, 84% had used at least one transmute to get there. The deck transmuted about 1.1 times a game on average by turn 10.

The model is simple and it leans against the deck: no mulligans, no card draw spells, no cantrips, no counting the backup combo. Real games will find the combo more often in both columns. The gap is the point. The same 99 cards, with the same four ordinary tutors, find their combo more than three times as often when the transmute cards are allowed to transmute.

The run also shows the cost. Each transmute is three mana that puts nothing on the battlefield, and you pay it at sorcery speed with your shields down. The deck that transmutes on turn 3 and turn 4 has done nothing else on those turns. If you want the odds for your own list, the MTG odds calculator works out how likely you are to draw a card by a given turn.

All 14 transmute cards

Every card with transmute, sorted by how many Commander decks play it (EDHREC, 11 November 2026). Prices are the cheapest regular printing on Scryfall on the same day. 8 of the 14 cost less than a dollar.

The top three, Muddle the Mixture, Drift of Phantasms and Tolaria West, make up 65% of the 482,162 transmute slots across EDHREC’s decks. Muddle the Mixture alone is in 200,913. The pattern is the same all the way down the table: the cards people play are the ones that are fine on their own. A counterspell, a blocker and a land get played. Netherborn Phalanx and Grozoth mostly sit in binders, because six and nine mana are a lot to pay for the front half and there are few cards at those numbers worth finding.

Combos that share a mana value

Transmute is at its best when both halves of a combo have the same mana value, because one card then finds whichever half you’re missing. These are the pairs that line up. Every mana value and Commander legality below was checked on Scryfall on 11 November 2026.

A second trick is the chain. A transmute card can find an ordinary tutor that shares its number, and that tutor finds anything. Drift of Phantasms finds Solve the Equation; Dimir House Guard finds Diabolic Tutor. It costs six or seven mana across two turns, so it’s a late-game line, but it means almost every transmute card in a deck leads to the card you want. For the wider field, see our best tutors in MTG guide.

Is transmute legal? Every format

No transmute card is banned or restricted in any format, and none is on the Commander Game Changers list. Tutors do matter for Commander brackets, though: a deck with a dozen of them and a two-card combo is not a Bracket 2 deck, whatever it cost. Legality checked on Scryfall on 11 November 2026.

Budget Oona transmute deck ($62)

Oona, Queen of the Fae is a blue-black 5/5 flyer for six with one ability: pay {X} and one blue or black mana, and an opponent exiles the top X cards of their library. With infinite mana, that’s every opponent’s whole library. The deck exists to make infinite mana, and it uses 12 transmute cards to find the pieces. 36 lands, 14 mana rocks, average mana value 2.89 without lands, no Game Changers. Total $61.81 at the cheapest regular printing of each card. For a public Oona list you can open in the builder, see Midnight Mischief on KrakenTheMeta, or browse the community decks.

How the deck plays

• Turns 1 to 3: rocks. The combo needs mana rocks on the battlefield, so every rock you cast is ramp now and a combo piece later. See the best mana rocks for upgrades.
• Turns 3 to 6: transmute for what’s missing. Muddle the Mixture, Dimir Infiltrator and Shred Memory each find Isochron Scepter or Dramatic Reversal. Hold counterspells for the turn you go off.
• The combo. Cast Isochron Scepter and exile Dramatic Reversal under it. With rocks that make at least three mana, pay {2} to copy Reversal, untap the Scepter and the rocks, and come out ahead each time. That’s infinite mana, as long as one of the rocks makes blue or black.
• The win. Cast Oona and exile every opponent’s library; they lose when they next have to draw. Or cast Exsanguinate for a million. If Oona is countered, Blue Sun’s Zenith and Stroke of Genius turn the mana into as many cards as you want.
• The backup. Peregrine Drake and Deadeye Navigator, paired through soulbond, make infinite mana once your lands produce three or more. Brainspoil finds the Drake and Ethereal Usher finds the Navigator.

The cards worth finding

The best targets in the list, with the cheapest regular printing on 11 November 2026.

The 10 most expensive cards

Those ten are 48% of the deck’s price. Isochron Scepter is the only card that costs more than a few dollars, and it’s half the combo. Be honest with your table before you shuffle up: this is a two-card infinite combo deck with a dozen tutors. It’s cheap, but it isn’t casual.

How to beat transmute

The cheapest answer costs nothing: attack the player who is spending three mana a turn on tutoring. A deck that transmutes twice has built no board.

Transmute FAQ

What does transmute do in MTG?

You pay the transmute cost and discard the card from your hand, then search your library for a card with the same mana value, reveal it and put it into your hand. You can only do it when you could cast a sorcery.

Can you counter transmute?

Not with a normal counterspell. Transmute is an activated ability, so only cards that counter abilities can stop it. The usual play is to counter the card it found.

Is transmute an instant-speed ability?

No. Every transmute card says “Transmute only as a sorcery”. You need your own main phase and an empty stack.

Can Tolaria West find a land?

Yes. Lands have mana value 0, and so does Tolaria West. It can find any land, plus any spell with no mana cost or a cost of {0}, such as Pact of Negation.

What is the mana value of a card with X in its cost?

In your library, X is 0. Exsanguinate has mana value 2 and Blue Sun’s Zenith has mana value 3, so Muddle the Mixture finds the first and Drift of Phantasms finds the second.

Does transmute count as discarding?

Yes. Discarding the card is part of the cost, so abilities that trigger when you discard will trigger, and the card ends up in your graveyard.

Do you have to find a card?

No. You can search and choose not to take anything, though you’ve still paid the cost and discarded the card.

How many transmute cards are there?

14. Thirteen are from Ravnica: City of Guilds (2005) and one, Tolaria West, is from Future Sight (2007).

Is transmute legal in Commander?

Yes. All 14 cards are legal in Commander as of 11 November 2026, and none is banned in any format where it’s legal.

What is the best transmute card?

Muddle the Mixture. It’s a two-mana counterspell that also finds any card with mana value 2, and it’s in 200,913 Commander decks on EDHREC (11 November 2026), ahead of Drift of Phantasms at 59,768 and Tolaria West at 52,857.
