12% of tracked Gruul-identity decks on Playgroup Live run Mossfire Valley, with 76% of drawn copies reaching the battlefield and a median first-cast turn of 4.

Mossfire Valley slots into any Red-Green deck as a cost-efficient dual land, and the Playgroup Live dataset backs up its reputation as a reliable includes. 12% of tracked decks carry it, spread across 607 distinct lists out of 4920 in the dataset.

When a copy reaches a player's hand, 76% of those instances are played before the game ends. Median first activation lands on turn 4, which is later than you might expect for a land, reflecting that the {1} activation cost means players sometimes prioritize untapped sources early and deploy Mossfire Valley when fixing is needed in the mid-game. Once it hits the battlefield, it sticks: 90% of cast copies remain in play at game's end.

The data is well-spread: 536 distinct players have brought this card to tracked games, and no single player accounts for more than a small fraction of the sample. That breadth adds confidence that what we see reflects real format behavior rather than one prolific grinder's preferences.

≥ +3.6pp

Players who cast this card win 30% of the time (n=210) , vs 20% when it never left the library (n=811).

When players drew this card but left it in hand, they won 30% (n=61) — 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 +9.8pp; 95% confidence interval +3.6pp to +16.0pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Frequently Asked

How often is Mossfire Valley drawn in a Commander game?

Across 1204 tracked multiplayer games where Mossfire Valley was in the deck, it was drawn 23% of the time. That is consistent with a singleton land in a 100-card deck. Of 293 drawn instances, 76% were played before the game concluded.

What turn does Mossfire Valley typically come down?

The median first-cast turn in multiplayer games is 4, with the distribution showing a cluster of early plays (turns 1-2, when it shows up in an opening hand) and a longer tail into the mid-game. The {1} activation cost means players occasionally let it sit a turn or two when untapped red or green sources are available. The p25 lands at turn 3 and the p75 at turn 8, showing a wide spread.

How sticky is Mossfire Valley once it enters the battlefield?

90% of Mossfire Valley copies that were played remained on the battlefield at the end of the game. This is expected for a land with no enters-the-battlefield condition or sacrifice effect. Once it resolves, it almost always stays.

Is Mossfire Valley legal in Commander?

Yes. Mossfire Valley is legal and unrestricted in Commander, as well as in Legacy, Vintage, Duel Commander, Oathbreaker, and Premodern. It is not legal in Modern, Pioneer, Standard, Pauper, or Brawl.

Which commanders most commonly pair with Mossfire Valley?

On Playgroup Live, Cloud, Ex-SOLDIER leads the list followed by Bello, Bard of the Brambles. Both commanders sit in the Gruul (Red-Green) color space that Mossfire Valley naturally slots into. The spread across many commanders is broad, which suggests the land is a format staple for the color pair rather than a narrow include for any one strategy.

Does casting Mossfire Valley correlate with winning?

In 210 tracked participations where Mossfire Valley was played, the normalized win rate was 30%. The baseline for decks where it stayed in the library was 20%. The difference is a directional early signal, not a conclusive finding, given the sample sizes and the nature of mana-fixing lands, which enable other cards to win rather than winning directly themselves.
