Friendly greetings and welcome to a deck tech for Elrond, Moon-ReaderElrond, Moon-Reader. I'm John Sherwood, Theft deck apologist, demonstrating how this new legend from The Hobbit will help you enjoy playing Commander with other peoples' cards.

Lunar Literacy

Magic's return to Middle-earth brings us a new take on Elrond, a familiar character with flavorful abilities from J.R.R. Tolkien's beloved epic fantasy.

In the story, Elrond interprets some runes which only appear in the light of the moon. With the aid of Elrond's translation, Thorin Oakenshield and his party embark from RivendellRivendell on a quest to reclaim their ancestral home, The Lonely MountainThe Lonely Mountain. Consistent with Magic design, Elrond's knowledge is represented through card draw. His second ability also has thematic roots, sending creatures on a journey to exile (there) and back again.

Even as the card seamlessly blends lore and mechanics, it's surprisingly safe for a legendary creature in 2026. Both abilities on Elrond, Moon-ReaderElrond, Moon-Reader have very clear guard rails. Limiting its triggered ability to once per turn staves off easy combos and predictable finishes with stale cards like Thassa's OracleThassa's Oracle and Laboratory ManiacLaboratory Maniac. Meanwhile, the staggering cost of functionally restricts its activated ability to fair play only.

A commander with this many caveats would struggle in Brackets 4 or 5, but the combination of these two abilities makes Elrond a prime candidate for social games in Bracket 3.

Despite power-limiting restrictions, Elrond manages to be open-ended to a surprising range of possible deck themes. Many blue and colorless creatures possess interesting, even potent, activated abilities. Along the journey to write this article, I gave serious consideration to Persistent PetitionersPersistent Petitioners, or pingers like Prodigal SorcererProdigal Sorcerer.

As I combed through search results for creatures with activated abilities, I noticed a line connecting both of Elrond's abilities to one of my favorite strategies: beating people with their own cards.

Elrond's Entourage

Creatures with activated abilities to gain control of opponents' creatures make up the core of this Elrond, Moon-Reader theft deck.

Control MagicControl Magic on a stick has been a blue card template since Old Man of the SeaOld Man of the Sea in Arabian Nights. Unfortunately, that particular card is on the no-good Reserved List for no good reason. If anyone reading this article can do something sensible about that problem, kindly get to it. In the meantime, I'm excluding Old Man of the Sea from the final deck list because it costs more than the entire deck list combined.

On the bright side, the Old Man's successors from SeasingerSeasinger to Simic ManipulatorSimic Manipulator go easy on the wallet.

Typically, the exchange rate for targeted removal is one object for one card. Control Magic effects improve this ratio in your favor, because you spend a card and gain an object, while your opponent loses an object. Repeatable control effects, like Beguiler of WillsBeguiler of Wills and Empress GalinaEmpress Galina, incrementally build a board advantage.

By activating one ability per turn, Elrond reliably draws multiple cards per round. Each resolution of a control effect shifts the balance of the board state in our favor, and fills our hand with resources to win a war of attrition.

One of my favorite features of this deck is the age of the cards with activated abilities for the Theft theme. These pieces average 23 years since first printing, and none of them are newer than 2013. Over time, power creep replaced the classic template of these activated abilities with enters-the-battlefield effects. The current peak is Agent of TreacheryAgent of Treachery, a card never played with good intentions, because it's easily repeatable to lock players out of the game.

Lock-outs belong in Bracket 4. Since this is a Bracket 3 deck, we still want our opponents to have a chance to participate in a meaningful way. Agent of Treachery will sit this one out because it's a signpost for oppressive gameplay.

Reinforcements

Sadly, only 13 creatures in the deck steal other permanents via activation. That's pretty slim pickings for a deck's main theme. We're relying on Elrond's easy card draw trigger to churn through the deck and get to those pieces. Packing more sizzle into this game plan requires calling for backup. We'll do this from two angles: copying activated abilities, and untapping creatures.

Copying activated abilities reinforces the central theme, and three other Universes Beyond sets provided creatures for the job: Adric, Mathematical GeniusAdric, Mathematical Genius from Dr. Who, Gogo, Master of MimicryGogo, Master of Mimicry from Final Fantasy, and Echo, Perceptive ProdigyEcho, Perceptive Prodigy from Marvel Super Heroes.

Incorporating creature-based untappers packs the deck with more activated abilities to trigger Elrond. The best untapping abilities can target any permanent type like Vizier of Tumbling SandsVizier of Tumbling Sands and Ioreth of the Healing HouseIoreth of the Healing House.

These untappers can squeeze extra mileage out of the theft abilities, untap creatures in combat, or untap lands for more mana. Their value is in their versatility.

Dorks for Draws

More often than not, card draw and ramp packages are repetitions of the same staples. This goes beyond the ubiquity of Sol RingSol Ring and Arcane SignetArcane Signet. Blue decks typically rely on noncreature artifacts for ramp, but with Elrond in play our mana dorks pay dividends. It pays to leave a dork or three open at the end of your turn, instead of using creature-sourced mana all at once.

Blue decks already love to leave mana up for interaction. By utilizing creatures like Silver MyrSilver Myr for this role, Elrond can draw extra cards on opponents' turns. Your opponents don't need to know if you have that CounterspellCounterspell in hand. Even if you don't use the mana to pay costs, you can still tap a dork to draw a free card on the end step before your next turn.

Politics and War

Normally, the best time to give back a stolen creature is after eliminating the owner from the game. Situationally, it might be prudent to return a creature sooner. Maybe another player can make better use of their own creature to deal with a common threat. Perhaps we need an opponent to have a blocker so they can stay in the game until the opportune moment. Consider returning creatures to other players as an act of good faith, or goods for making deals at the table.

Elrond comes with a built-in return to sender, but seven mana is a steep price to pay for politics. Bounce spells like UnsubstantiateUnsubstantiate are made to be removal, but a theft deck can use them as a bargaining chip.

Blink is more useful than bounce in this regard, since the object goes back to play instead of back to hand. Elrond's activated ability costs way too much mana to be reliable. BlurBlur costs less mana, and draws a card. Three mana is a much better rate for a spell that is functionally modal. It might as well say choose one: return a creature to an opponent, protect a creature from targeted removal, or rebuy an enters effect.

There are times when diplomacy fails, and you need a spell to go to war. Ghostly FlickerGhostly Flicker is blue's best blink, with a wider range of eligible targets. Most significantly, Ghostly Flicker returns the permanents under your control. Because they enter as new objects they aren't subject to return clauses like Callous OppressorCallous Oppressor and OvertakerOvertaker.

Many of blue's theft effects have terms by which you have to give the object back. Ghostly Flicker alters the deal.

If You Can't Take 'em, Make 'em

Cloning is another approach to playing with your opponents' toys. Thousands of creatures have activated abilities, and there are great odds one of your opponents will play something worth mimicking. A few clones come standard with activated abilities, such as ShapesharerShapesharer and Zygon InfiltratorZygon Infiltrator.

The Shapesharer's copy effect is temporary, but it comes on a cheap body. This deck needs some functional two-drops because most theft and copy effects cost four mana or more. Spending three mana to copy the best thing on the board and drawing a card with Elrond is a decent return on investment.

Zygon Infiltrator is also temporary, with a side dish of soft removal. The activation cost buys two turns of copying, but the most important feature here is repeatability. With enough mana, or a discount from Training GroundsTraining Grounds, Zygon Infiltrator is a machine that can neutralize blockers, shut down engines, and lock down threats.

Similar to stealing, cloning appears in nearly every set going back to Alpha. "CloneClone with set's mechanic" is a design template as ubiquitous as bear with set's mechanic. In contrast, very few spells make token copies of opponents' creatures without strings attached or hoops to jump through. Theoretical Duplication and See Double are two of the best, simply by virtue of speed and cost.

Three or four mana for instants which are both economical and versatile. Economical and versatile are really the name of the game with a deck like this.

Conclusion

This legend might be new in 2026, but it opens lines for some of Magic's oldest cards and some of blue's most interesting effects. Theft and clone decks are fun because you get to piece together board states and synergies that don't normally happen within the confines of a 100-card deck with singleton and color identity rules.

From an opponent's perspective, theft and clone decks are fun to play against, because they inherently involve counterplay instead of solitaire. If you tend toward solitaire Commander, please get out of your comfort zone and play the game with the other people at the table.

A deck like this is also limited in power to whatever your opponents are doing, so there's no risk of winning faster than Bracket 3's intended six or more turns. Because it's reactive, it doesn't contain any of blue's usual win conditions. It will take skill and patience to identify the right pieces to steal or copy to assemble a winning board state. If you love challenging, interactive gameplay, then maybe this brew is for you.
