Marsh Flats
Marsh Flats appears in 9% of tracked Commander decks on Playgroup Live. When drawn, 71% of copies reach activation before the game ends, with a median first-activation turn of 4.0.
Marsh Flats is a fixture in black-white and multicolor Commander lists. Across 1028 tracked games on Playgroup Live, it sits in 9% of all decks that have played a live game, appearing in 703 of the 8080 distinct tracked decks.
As a fetch land, Marsh Flats behaves differently from spells in the funnel data. Its "cast" event is the moment it sacrifices to search, so 71% of drawn copies being activated reflects how reliably players find a window to use it. The median activation lands on turn 4.0, but the distribution is front-loaded: a meaningful cluster fires on turn 1 from the opening hand. Because the land sacs itself on resolution, battlefield stickiness is structurally low and not a useful signal here.
The data is well-spread across the player base. 444 distinct players have brought Marsh Flats to a tracked game, and no single player accounts for more than a small fraction of instances, which supports treating these figures as a genuine cross-meta signal rather than one person's playstyle.

First-cast turn
n=220The "good card" funnel
1289 brought · 444 playersOf 1289 Marsh Flats copies brought to games, 309 were drawn, 220 of those were activated to search, and the vast majority moved to the graveyard on resolution as designed.
Players who cast this card win 30% of the time (n=214) , vs 24% when it never left the library (n=891).
When players drew this card but left it in hand, they won 33% (n=87) — 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 +5.6pp; 95% confidence interval -0.5pp to +11.7pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
355 instancesMost Marsh Flats copies never leave the library in a given game, a normal outcome for any singleton in a 100-card deck. Among those that do reach a hand, the graveyard is the expected final destination once the land sacrifices to fetch.
