40% of tracked Commander decks with black-red in their color identity run Smoldering Marsh, and 79% of drawn copies reach the battlefield before the game ends.

Smoldering Marsh sits in 40% of the 5354 Commander decks tracked on Playgroup Live, making it one of the more consistently adopted dual lands among black-red and Mardu strategies. Across 3658 multiplayer games, it has been brought to the table 4203 times.

The draw-to-play rate of 79% is healthy for a land. Lands that enter tapped create a real decision point about timing, but the data shows players move them to the battlefield at a high rate when they do reach their hand. Median first play lands on turn 4, with a mode of turn 1, confirming that copies found in opening hands go down immediately.

The concentration profile is strong: 1532 distinct players have brought this card to tracked games, and the single heaviest contributor accounts for just 1% of all instances. That spread lends meaningful weight to the numbers here.

≥ +2.0pp

Players who cast this card win 26% of the time (n=783) , vs 21% when it never left the library (n=2591).

When players drew this card but left it in hand, they won 21% (n=198) — about the same as leaving it in the library. Those players survived long enough to draw it, so the gap above is about the card resolving, not just about surviving.

Observed gap +5.1pp; 95% confidence interval +2.0pp to +8.3pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Most Smoldering Marsh copies end the game on the battlefield, a natural result for a land that sticks once played. The library bucket is small relative to other singletons because lands tend to be played as soon as they are found.

Frequently Asked

How often is Smoldering Marsh drawn in a Commander game?

In 3658 tracked multiplayer games where Smoldering Marsh was in the deck, it was drawn 26% of the time. That is normal for a singleton in a 100-card deck. Of 1079 copies that reached a player's hand, 79% were played before the game concluded.

What turn does Smoldering Marsh usually hit the battlefield?

Median first-play turn is 4, with the mode falling on turn 1. The distribution is spread across the early game: copies found in opening hands go down on turn 1, while later draws cluster around turns 3 through 5. The 90th percentile stretches to turn 9, reflecting copies found deep into longer games.

Does playing Smoldering Marsh correlate with winning?

Win rate when the card reaches the battlefield is 26%, compared to 21% in games where it stayed in the library the whole time. The difference is a directional positive signal, but both sample sizes point toward a modest, not dramatic, effect. Read it as consistent with the card pulling its weight, not as proof it wins games on its own.

Is Smoldering Marsh legal in Commander?

Yes. Smoldering Marsh is legal in Commander and in most other major constructed formats, including Legacy, Modern, Pioneer, Vintage, Historic, and Timeless. It is not legal in Standard, Pauper, or Pauper Commander. The card has no Commander ban.

Why does Smoldering Marsh show up in three-color decks if it only produces black and red mana?

Smoldering Marsh is a dual land with the Swamp and Mountain subtypes, so it counts as both for the purposes of cards that care about basic land types, such as fetchlands. Three-color commanders in Grixis (blue-black-red), Jund (black-red-green), and Mardu (black-red-white) all contain black and red in their identity, which is why they appear at the top of the commander distribution.

How concentrated is the Smoldering Marsh data across players?

The dataset is well-spread. 1532 distinct players have brought Smoldering Marsh to at least one tracked game, and the single most frequent contributor accounts for just 1% of all instances. That breadth makes the play patterns here a stronger cross-table signal than data dominated by a small group of regulars.
