Last updated on December 22, 2025

Ever had that feeling that your Commander decks are just too budget to compete? They’ve all got better mana rocks, maybe, or some broken nonsense like Smothering Tithe or an OP commander or two. And they’ve got a lot of tutors to find them all.

What if I told you that you could get a decent tutoring suite in blue and black for budget prices?

Transmute is the secret to getting your tutor game on from all the way back in Ravnica: City of Guilds. Make no mistake, these are far less powerful tutors than the greats, like Vampiric Tutor or Mystical Tutor, but you can get in the ballpark for the same casting cost as Grim Tutor.

Let’s see how this mechanic ticks!

How Does Transmute Work?

Transmute is an activated ability that allows you to discard the card from your hand and pay some form of three Dimir mana (Either , , or ) to search your library for a card with the same mana value as the discarded card.

Discarding the transmute card is the cost of activating the ability, and the tutoring happens upon resolution of the ability.

The History of Transmute in MTG

Transmute first appeared on 13 cards in 2005’s Ravnica: City of Guilds, then on one card in 2006's Time Spiral and one more in Future Sight in 2007. That’s it.

With a Storm Scale rating of 9, transmute is unlikely to see the light of day again anytime soon. Mark Rosewater suggests that mechanics built on tutoring are bad for the variability of the game.

Is Transmute a Spell In MTG?

No, transmute is an activated ability. You're not casting anything, though you can interact with the ability via stifle counterspells. Of course, casting a spell that has transmute certainly counts as casting a spell, though transmute is completely irrelevant in that case.

Does Transmute Count as Being Cast?

No, transmute isn’t a spell, and activating transmute does not count as casting anything.

Is Transmute Instant Speed?

No, all transmute cards have the rules text ”play only as a sorcery.”

Can Transmute Be Countered?

Transmute can’t be countered by typical counterspells. Only cards that counter activated abilities can do it, like Mirrorshell Crab.

Can You Respond To Transmute?

Transmute uses the stack, so you can respond to it with instant-speed spells and effects. To stop the transmute you’d need a spell like Voidslime that can counter activated abilities, or a spell like Discontinuity that ends the turn while voiding the stack.

You can't respond to the actual discarding of the card, since that's the cost to activate a transmute ability.

Can You Transmute For A Land?

Yes, you can transmute for a land depending on the card. Tolaria West can only tutor up cards that cost 0, and searching up a land counts for that. Other transmute cards can pull up MDFCs. Agadeem's Awakening, for example, has a mana value of 3, so you could transmute a card like Perplex to fetch it up.

Can You Copy Transmute?

Yes, you can copy transmute. Cards like Rings of Brighthearth can copy activated abilities like cycling and transmute, so the Rings let you tutor up two cards, so long as they both have the exact mana value of the transmuted card.

Why Is Tolaria West A Good Card?

Tolaria West can tutor up anything that costs 0 mana. So that includes other utility lands, utility artifacts like Chalice of the Void and Tormod's Crypt, X-cost spells like Endless One, 0-cost spells like Pact of Negation, and even no-mana suspend spells like Glimpse of Tomorrow.

That’s a lot of options for Commander.

A 3-mana tutor with limited targets is too slow for just about any other format, but there are folks who rock it in Amulet Titan builds in Modern to find Summoner's Pact, Tron players who use it to grab those coveted Urza lands, and even Living End decks to grab their namesake cards.

Best Transmute Cards

These cards are really only as valuable as the cards they can fetch since none of them are really all that playable for their face cost. All of them do something given that criteria, but some have a bit more utility than others.

Honorable Mention: Grozoth

Grozoth can find some really expensive stuff when it enters the battlefield if you’re in a reanimator shell. How do you cast it all? Good question.

But if you’re in Izzet () you should know that this can transmute for your Blasphemous Act. The broken stuff at 9 mana you want is costly already (see Expropriate), so why not already have better tutors if that’s your Commander vibe?

#6. Brainspoil

The only transmute card that tutors for a card with a mana value of 5, Brainspoil is valuable for decks that need something like Sanguine Bond or Gray Merchant of Asphodel.

#5. Dimir House Guard

A sac outlet that you can pitch to find some nasty 4-drop like Sheoldred, the Apocalypse, Dimir House Guard has its place if you’re in black and need a lot of tutors.

#4. Dizzy Spell

The only tutor for mana value 1, Dizzy Spell is a Limited-level combat trick that can tutor up all sorts of fun stuff from Swords to Plowshares to my favorite, Mystic Remora.

I’m sure you can list your own favorites. Being able to immediately cast a cheap tutor target is especially nice.

#3. Perplex

Perplex gets less valuable as a counter the more graveyard decks proliferate in EDH, but having a weak counter you can convert into a Teferi, Time Raveler, a Toxic Deluge, or so many other powerful things when it needs repurposing is great.

#2. Muddle the Mixture

A tutor you can use as a counterspell is pretty flexible. Muddle the Mixture is in a lot of Commander decks because 2-mana cards are often exactly what you need in various situations, so the fact that this isn’t Demonic Tutor is okay.

Maybe you want a Sylvan Library? Thassa's Oracle? Cyclonic Rift? There are a lot more great options at this mana value.

#1. Tolaria West

Tolaria West works in a few Modern decks like Amulet Titan, and in EDH it’s a pretty common tutor. You can see why.

The fail case for it is a blue tap land, but the upside of being able to discard it to find another land or a control piece in decks that recur lands is pretty awesome.

Is Transmute Good?

Yes, transmute is good. As far as tutors go, these are undiscovered gems you can pick up for a pretty reasonable cost. The trick is to figure out your tutoring purpose.

If you just need an extra copy of a winning card, adding a transmute card as a supplement to your more expensive tutor suite is a decent way to get it out of your giant Commander deck.

If you’re playing a flexible deck looking for a toolbox of answers, grabbing all three transmute cards at 2 or 3 mana value and then sifting your deck to prioritize those mana costs when there are choices to be made for certain slots is a good way to get more of what you want in your hand.

These aren’t as powerful as cards like Grim Tutor, but it seems like these transmute cards are just too old and obscure for most players. They’re likely a good buy in a deck with some black or blue, especially if you’re on a budget.

Wrap Up

We’re likely not going to see this budget-friendly mechanic again since a set mechanic that tutors is probably pretty miserable for a format, but the cards that exist are there for intrepid Commander players to grab.
