Shipwreck Marsh
Shipwreck Marsh appears in 15% of tracked Commander decks on Playgroup Live. When drawn, 82% of copies reach the battlefield, and once there, 94% stay through end of game.
Shipwreck Marsh is a blue-black dual land that enters untapped once you control two or more other lands, making it a strong turn-three-and-beyond mana source for any Dimir or Grixis shell. Across 1098 tracked multiplayer Commander games on Playgroup Live, it sits in 15% of participating decks.
The funnel is clean: 82% of drawn copies are played before the game ends, with a median first-cast turn of 4. That high play-through rate reflects what you'd expect from a land: players rarely hold a land in hand by choice. Once it hits the battlefield, 94% stickiness confirms it almost never gets removed or sacrificed. The data is well-distributed across 517 distinct players, with no single contributor exceeding 15% of the tracked instances, which adds confidence to the directional signals here.
The top commander pairings skew heavily toward blue-black and Grixis strategies, consistent with Shipwreck Marsh's color identity restriction. It fits any 100-card singleton deck running blue and black, and is legal in Commander, Legacy, Modern, Pioneer, Vintage, and more.

First-cast turn
n=229The "good card" funnel
1158 brought · 517 playersOf 1158 copies brought to games, 280 were drawn, 229 of those were played, and the vast majority remained on the battlefield through end of game.
Players who cast this card win 23% of the time (n=212) , vs 22% when it never left the library (n=719).
When players drew this card but left it in hand, they won 27% (n=46) — 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 +0.9pp; 95% confidence interval -5.1pp to +6.9pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
339 instancesMost Shipwreck Marsh copies never leave the library in any given game, a structural reality of 100-card singleton decks where even staple lands are drawn in fewer than one in three games.
