Polluted Delta
Polluted Delta lands in 10% of tracked Commander decks and, when drawn, reaches the battlefield 67% of the time, with a median first-use turn of 4.0.
Polluted Delta sits in 10% of the 8540 Commander decks tracked on Playgroup Live, appearing across 861 distinct lists. That number covers only decks with a Blue or Black color identity, so the penetration rate within eligible archetypes is considerably higher than the headline figure suggests.
As a fetch land, Polluted Delta behaves differently from almost any other card in the format. It enters the battlefield and immediately sacrifices itself to find an Island or Swamp, which means its "stickiness" metric is structurally near zero by design, not by weakness. The 67% draw-to-play rate tells the real story: when players draw it, it resolves quickly. The median first-use turn is 4.0, and the mode is turn 1, reflecting how many players keep opening hands that contain it and fire it immediately to thin the deck and fix mana.
The commander distribution is broad. 518 distinct players have brought Polluted Delta to tracked games, and no single player accounts for more than a small fraction of the dataset, which gives the numbers here reasonable spread across archetypes ranging from five-color goodstuff to tight Dimir control builds.

First-cast turn
n=284The "good card" funnel
1656 brought · 518 playersOf 1656 Polluted Deltas brought to tracked games, 425 were drawn, 284 of those were activated, and the overwhelming majority moved immediately to the graveyard as the fetch resolved.
Players who cast this card win 34% of the time (n=271) , vs 25% when it never left the library (n=1100).
When players drew this card but left it in hand, they won 33% (n=138) — 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 +8.5pp; 95% confidence interval +3.1pp to +13.9pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
490 instancesThe graveyard dominates Polluted Delta's final-zone chart by design. Every activation sends it there directly, so the library figure represents copies that were never drawn and the battlefield count is near zero, which is exactly how a fetch land is supposed to behave.
