Murders at Karlov Manor is the set where the Magic booster aisle changed shape. It launched on February 9, 2024 as the first premier set built around Play Boosters, retiring both Draft and Set Boosters in a single move, and every Standard set since has followed its configuration. If you are pricing an MKM booster box today, working out what a Play Booster actually contains, or trying to find the serialized Ravnica City guild leaders, this page covers the whole sealed lineup and where the market sits now.

Thirty-six Play Boosters of 14 cards. The Play Booster recipe debuted here: roughly six commons, three uncommons, a wildcard of any rarity, a guaranteed rare or mythic, a traditional foil of any rarity, a land, and a token or art card, with one pack in eight swapping a common for a card from The List or Special Guests. The result sits between the old Draft Booster and Set Booster in both card count and excitement, and it is the box you want if you plan to draft the set.
The pack count is worth pausing on, because it is the most common mistake people make when comparing MKM to a newer box. Play Booster boxes launched at 36 packs, matching the Draft Booster boxes they replaced, and held at 36 through Foundations in November 2024. Wizards cut them to 30 packs from Aetherdrift in February 2025 while keeping the per-pack price the same, so a 2024 box holds six more packs than a 2025 or 2026 one and any per-pack comparison has to account for that.
Wizards had suspended published MSRPs by 2024, so there is no official list price for MKM; launch retail was around $140-$150, roughly $4 a pack. Boxes now trade at $95-$175 with most sales between $110 and $130, or about $3.10-$3.60 per pack, which is among the cheapest draft-ready product in Magic.
Twelve Collector Boosters of 15 cards, each an all-premium pack with foil commons and uncommons, multiple Booster Fun rares and mythics, a foil land and a foil token. This is the only place the serialized Ravnica City cards and the invisible ink dossier treatment appear. MKM Collector boxes opened near $250 and now sell in a $270-$450 band, clustering around $330-$400.
Nine Play Boosters, a foil alt-art promo, 30 basic lands, a spindown die and a storage box. It is the cheapest way to sample the set without committing to a box, and it generally runs $40-$65 now.
Four 100-card preconstructed decks: Deadly Disguise (Naya, disguise and cloak), Revenant Recon (Dimir, surveil and evidence), Deep Clue Sea (Bant, Clue tokens) and Blame Game (Boros, suspect). Each ships with a foil face commander, a Collector Booster Sample Pack, tokens and a deck box. Sealed decks run $30-$60 apiece, with Deep Clue Sea usually the priciest.
Six Play Boosters, a year-stamped foil rare or mythic, a spindown die and a deck box. Prerelease kits from a rotating-out set are mostly a nostalgia buy now, and they trade at $25-$40.
Not a booster product at all. This is a standalone board game crossover with Hasbro's Clue that contains four preconstructed Magic decks plus a murder-mystery game layer, released alongside MKM. It has its own collector following and trades well above its original price, generally $80-$140 depending on condition of the box.
A Play Booster case is six boxes and a Collector Booster case is six boxes. Case-fresh product is the only way to fully rule out resealing, which matters more for Collector boxes than for Play boxes at these price levels.
The serialized run is the headline. Seven Ravnica City cards, one for each of the surviving guild leaders, were printed in double rainbow foil at 250 individually numbered copies each, English text only, and appear exclusively in Collector Boosters regardless of the language on the pack. That is a tighter run than most serialized cycles, and pulls still surface for four figures when they change hands.
Underneath that sit two showcase frames built for the murder-mystery theme. Showcase magnified cards, thirty in total, frame the art behind a detective's lens. Showcase dossier cards, forty-one of them, present characters as case files, and a subset of those received an invisible ink treatment that is Collector Booster exclusive and reads as though the card has been dusted for prints. Borderless surveil lands and the full-art Impossible basic lands round out the set, and the surveil land cycle has held its value better than anything else in MKM because Standard and Pioneer both want them.
Straight singles value is thin. Anzrag, Delney and Massacre Girl were the early standouts and none of them carry a box on their own. Wizards publishes Collector Booster slot contents rather than per-card odds, so treat any listing claiming a specific serialized hit rate as marketing.
Honestly, not as an investment. MKM was printed to demand during a heavy 2024 release calendar, it sold in large volume, and its singles never developed the top end that supports box prices. A Play Booster box at $120 contains around $75-$95 of realistic singles value at current levels even with 36 packs in it, which is a normal and unflattering result for an in-universe Standard set. The Collector box is a wider bet: the serialized guild leaders and invisible ink cards give it a real tail, but the median box comes nowhere near $370 in content.
What MKM does have going for it is drafting. It is a well-regarded limited environment, boxes are cheap, and the 36-pack configuration means a single box seats a full eight-person draft with packs to spare, which a 30-pack box from 2025 onward does not. For running drafts at a kitchen table or a store night, this is one of the best value-per-pack choices on the shelf. Buy it to open, not to shelve. The one caveat on the other side is February 2027 rotation: once MKM leaves Standard, demand for its surveil lands may soften further, so do not treat the current price as a floor.
The reseal risk on MKM is concentrated in Collector Boosters, where a box that has had its packs weighed or swapped can look perfect from the outside. Check that the shrink is tight and uniform with a clean factory seam, that there is no adhesive residue or tool scoring at the flaps, and that the box does not shift or rattle when tilted. A Collector box that has been opened and rewrapped often shows a slightly looser fit and a seam that sits off center.
Loose Collector Boosters from unknown sellers are the highest-risk purchase in the set, because a serialized card sits in a heavier slot and mapped packs are a persistent problem. Counterfeit sealed boxes of Magic sets exist and have improved in quality, so compare the set symbol placement and the print sharpness of the box art against a known-good example. If you can, buy boxes pulled from a sealed case by a shop that will stand behind them.
Local shops still hold MKM stock from allocation and often price it below the online market because it has been sitting; the card shop directory will show you what is nearby, and a store is the only place you can look at the shrink before you pay. Card shows are good for Commander decks and Clue Edition copies. Online, these searches cut through the clutter:
A Play Booster box holds 36 packs of 14 cards. A Collector Booster box holds 12 packs of 15 cards. There were no Draft or Set Booster boxes for this set. Play Booster boxes were reduced to 30 packs starting with Aetherdrift in 2025, so newer sets hold six fewer packs than MKM.
Yes. MKM was the first premier Magic set to ship Play Boosters, and it replaced Draft Boosters and Set Boosters at the same time. Every Standard set since has used the same 14-card, 30-pack configuration.
Yes, but not for much longer. MKM rotates out of Standard in February 2027, alongside Outlaws of Thunder Junction, Bloomburrow and Duskmourn.
Seven Ravnica City guild leader cards, each limited to 250 individually numbered double rainbow foil copies, found only in Collector Boosters and always in English.
Sealed Collector Booster boxes sell for roughly $270-$450 as of September 2026, with most transactions between $330 and $400. They launched around $250.
Play Boosters are for drafting and for cheap volume. Collector Boosters are the only source of serialized cards and invisible ink dossiers, and cost several times more per pack for that access.
