The Infinite Combos WotC Ships in Precons
We scanned all 178 precon decklists in our database against Commander Spellbook: 16 ship with a two-card infinite combo straight from the factory — and the rate has jumped from 4% (2011–2022) to roughly one in five since 2024. The receipts, the bracket rules' "intentional" loophole, and what to do when the scan finds one in your deck.
You bought Fae Dominion because faeries are great and building from scratch is homework. You told your pod it's "basically a precon, Bracket 2-ish." And somewhere in those hundred cards, Wizards of the Coast sold you Hullbreaker Horror and Sol Ring in the same box — the single most popular two-card combo in Commander Spellbook's entire database, sitting in 335,626 registered decks.
Nobody snuck it in. It shipped that way.
We scanned all 178 unique preconstructed Commander decklists in the DeckCortex database — every ingested precon from the 2011 originals through this year's releases, Secret Lair drops included — against our local mirror of Commander Spellbook, counting only true two-card combos (4,744 variants; no three-card lines, no "technically"). The result: **19 of 178 precons (10.7%) contain a complete two-card combo, and 16 (9.0%) contain a two-card infinite combo.** Straight out of the shrink-wrap.
One in ten doesn't sound like much — until you sort by year.
The factory changed its settings
From 2011 through 2022, WotC shipped 94 distinct precon lists in our corpus. Exactly four of them contained a two-card infinite combo — 4.3%, and two of those were famous one-offs (more on them below). Most years the number was a flat zero.
Then the line bends:
| Era | Precons | With a 2-card infinite combo | |---|---|---| | 2011–2022 | 94 | 4 (4.3%) | | 2023 | 27 | 3 (11.1%) | | 2024 | 26 | 3 (11.5%) | | 2025 | 18 | 3 (16.7%) | | 2026 so far | 13 | 3 (23.1%) |
Nearly one in four of this year's lists — with the usual small-sample caveat, since 2026 is thirteen decks and counting. Take the last two years together and it's a solid one in five. Whatever the design philosophy was in 2016, it isn't the design philosophy now.
The full year-by-year census
| Year | Precons | With a 2-card combo | With an infinite combo | |---|---|---|---| | 2011 | 5 | 0 | 0 | | 2013 | 5 | 1 | 1 | | 2014 | 5 | 0 | 0 | | 2015 | 5 | 0 | 0 | | 2016 | 5 | 0 | 0 | | 2017 | 8 | 0 | 0 | | 2018 | 8 | 0 | 0 | | 2019 | 4 | 1 | 1 | | 2020 | 9 | 0 | 0 | | 2021 | 15 | 1 | 1 | | 2022 | 25 | 1 | 1 | | 2023 | 27 | 3 | 3 | | 2024 | 26 | 5 | 3 | | 2025 | 18 | 4 | 3 | | 2026 YTD | 13 | 3 | 3 |
The zeros are real zeros: seven separate years shipped nothing that Spellbook recognises as a complete two-card pair. The streak ends in 2021 and never comes back.
The receipts
Nineteen boxes, thirty-four combo instances — several products carry more than one line. The highlights:
Mind Flayarrrs (Baldur's Gate, 2022) and Fae Dominion (Wilds of Eldraine, 2023) — the pair from the intro, and WotC shipped it twice in two years. The loop is simple enough to teach at the bar: tap Sol Ring for , cast any zero-cost permanent, and Hullbreaker Horror bounces the Ring back to your hand; recast it for and the Horror bounces the zero-drop right back too. Every cycle nets one colorless mana and two spell casts — infinite mana, infinite storm count, pick a payoff. That third zero-cost permanent is the honest asterisk (more in the caveats below), but both halves of the format's #1 combo come out of one box. Two boxes, actually.
Creative Energy (Modern Horizons 3 Commander, 2024) is the poster child: two independent infinite-combat lines in one box. Satya, Aetherflux Genius — the face commander — attacks alongside Lightning Runner, copies it as a tapped-and-attacking token, and every Runner in the pile pays eight energy to untap the team and bolt on another combat phase. Don't have Satya out? Stone Idol Generator does it too, farming an energy counter per attacker until the Runner loop pays for itself.
Living Energy (Aetherdrift Commander, 2025) proves the energy experiment wasn't a one-off. Aetherwind Basker banks an energy counter per creature you control every time it attacks; Lightning Runner — yes, him again — spends eight to untap the team and buy another combat. Swing with both while you control six creatures and the ledger balances forever. That's Lightning Runner's third infinite line across two consecutive years of precons; at this point he's less a card than a recurring guest star.
Draconic Rage (Forgotten Realms Commander, 2021) gave Vrondiss, Rage of Ancients two separate dance partners. Give Vrondiss indestructible from any third card and either Scourge of Valkas or Warstorm Surge turns his Enrage trigger into a treadmill: token enters, token damage retriggers Enrage, new token, forever. Conditional, yes — the box still hands you both halves of two loops.
Blast from the Past (Doctor Who, 2023) hides the funniest one. The Fifth Doctor untaps your creatures and hands out +1/+1 counters at end step; Adric, Mathematical Genius copies that trigger for a pop, which your freshly untapped mana dorks keep paying. Infinite untaps, infinite counters, courtesy of a math teacher.
World Shaper (Edge of Eternities Commander, 2025) ships The Gitrog Monster next to Dakmor Salvage. Discard the Salvage to hand size, the Frog draws you a card for the land hitting your graveyard, you dredge the Salvage right back — and you're still over hand size, so you discard it again. Your whole library, milled on demand from the cleanup step. Spellbook counts this pair in over fifty thousand decks; WotC put it in one product.
And the census keeps going.
Riders of Rohan (The Lord of the Rings, 2023) hands Gilraen, Dúnedain Protector the perfect blink target in Village Bell-Ringer. Two mana and a tap exiles the Bell-Ringer and returns it on the spot, and its flash-ETB untaps your entire board — Gilraen included, so she's instantly ready for the next round. Infinite untaps for a cycle; once your mana creatures tap for three or more, the loop pays its own bill.
Family Matters (Bloomburrow, 2024) pairs Helm of the Host with Combat Celebrant. Bolt the Helm onto the Celebrant and every combat opens with a fresh, never-exerted hasty copy; that copy exerts as it attacks, untapping the team and bolting on another combat — where the Helm mints the next one. Infinite combats, and your whole board swings in every single one.
Miracle Worker (Duskmourn, 2024) is the sneakiest of the year. Unlock Secret Arcade // Dusty Parlor and every nonland permanent you control is an enchantment on top of its other types — including Ondu Spiritdancer, who copies any enchantment entering under your control. Her "only once each turn" rider is real; the trick is that every token is a brand-new Spiritdancer with its own fresh allowance, so each copy clones itself the moment it lands and the parade never stops.
Blight Curse (January 2026) runs the oldest engine in the museum: Hapatra, Vizier of Poisons plus Blowfly Infestation. Whenever a creature dies carrying a -1/-1 counter, Blowfly passes a counter to the next victim; Hapatra sees you place it and produces a 1/1 deathtouch Snake — itself a fresh one-toughness body for the next counter to kill. Every death seeds the next, and Flourishing Defenses sits in the same list as a full Hapatra stand-in, making Elves instead of Snakes off the very same trigger.
Honorable mention to the two ancestors. Power Hungry (Commander 2013) shipped Primal Vigor + Tooth and Claw: sacrifice two creatures to make one Beast token, Vigor doubles it into two, and those two feed the next activation — a token treadmill that loops for free and turns lethal the moment any death or ETB payoff is watching. Mystic Intellect (Commander 2019) built its box around Sevinne, the Chronoclasm, who freely copies the first spell you cast from your graveyard each turn: flash back Increasing Vengeance (or the aftermath half of Refuse // Cooperate) and let Sevinne's copy target the original still sitting on the stack — every copy births another copy for as long as you care to point. Those were the outliers of their era. Today they'd just be a Tuesday.
Even the non-infinite finds are on theme. Science! (Fallout, 2024) packs James, Wandering Dad // Follow Him next to Mechanized Production: investigate a handful of times off the Adventure half, enchant one Clue, and Production wins the game at your upkeep once the Clue count hits eight — about all-in. The Secret Lair deck literally named 20 Ways to Win carries three two-card win lines. A kicked Rite of Replication on Biovisionary puts you at six copies when the card only asks for four, winning at the end step. Drown in Dreams lets Triskaidekaphile — who removes your maximum hand size — draw to exactly thirteen cards and take the win at your next upkeep. And Maskwood Nexus makes every creature card you own a God, so The World Tree's activation fetches your entire creature library straight onto the battlefield. WotC liked that last line enough to ship it again five months later in Everyone's Invited!. At least the boxes are honest.
What the bracket rules actually say
Here's the part that keeps this from being a scandal piece. The official bracket system — in every revision since the February 2025 beta — restricts Brackets 1 and 2 to "no intentional two-card infinite combos." Intentional is the load-bearing word, and WotC spelled it out in the launch Q&A: "if you accidentally find an easy two-card combo in your deck, hopefully that's a good laugh for everyone and you now know to take it out for next time."
So no, your unmodified precon doesn't violate its label, and neither do you. But the census explains a quiet rules change: when brackets launched, precons were the reference point for Bracket 2 — and in the October 2025 revision, WotC formally cut that precon-equals-Core link. Look at the table above and you can see why. The products stopped fitting the definition years before the definition stopped pointing at the products. The same revision reworded combo limits into turn expectations ("about eight turns" for Core) and dropped Food Chain from the Game Changers list because the bracket combo rules already cover combos — the system leans on exactly the line our census is measuring.
The wider context makes the precon numbers look almost tame. ScryCheck's March 2025 scan of 17,603 player decks found combo lines climbing a perfect ladder: 5.8% of self-declared Bracket 1 decks, 17.2% of Bracket 2, 50% of Bracket 3, 85.4% of Bracket 4, 98.7% of Bracket 5 — 56% of the whole sample. Their conclusion, worth quoting: most of these "aren't dedicated combo decks — they're decks where two or three cards happen to go infinite together." Our own user-deck corpus is far too small for headlines — 37 public Commander lists of legal size — but it points the same direction: over half contain a complete two-card combo, and DeckCortex users skew tuned. Combos aren't an invasive species in casual Commander. They're the water.
And the mechanism is no mystery.
Sol Ring — half of the format's most popular combo — is in roughly 84–86% of all EDH decks by EDHREC's count, and 97.6% of the 27,986 cEDH lists in our own three-month corpus. When one combo piece is in nine decks out of ten, the second piece only ever needs to wander in. That's how a combo becomes "accidental": each card earned its slot on its own.
What you do with this
Two honest caveats before you do anything. Our 178 precons are the ones in our database — a complete population of what we've ingested, not a claim about every product ever printed. And "contains a combo" is a fact about deck construction, not gameplay: several of these lines need a third generic piece (a zero-cost permanent for the Hullbreaker loop, an indestructible grant for Vrondiss, a damage outlet for the snakes) and none of them assemble themselves without draws or tutors.
But here's the practical takeaway, and it's a thirty-second job: scan your own list. If WotC's own editors ship two-card infinites in one of every five recent products, the deck you've been upgrading for two years has almost certainly picked one up along the way. DeckCortex's deck analysis runs the same Spellbook matching we used for this census and shows you every complete and near-complete combo in your build, next to the bracket signals that actually matter.
Then make the call WotC already scripted for you: pull the piece and keep your Bracket 2 label clean — or keep the combo, move the sticker to 3, and say the quiet part at Rule 0. Both are fine. The only bad option is the one where your opponents' scan finds it before yours does.
