Shivan Reef
Shivan Reef sits in 30% of tracked Commander decks on Playgroup Live, with 70% of drawn copies reaching the battlefield and a median first-cast turn of 4.
Shivan Reef is the go-to Izzet dual land for Commander players who want untapped colored mana without a steep price tag. Across 998 tracked multiplayer games on Playgroup Live, it appears in 571 of 1932 distinct decks, a 30% inclusion rate that reflects its role as a reliable mana-fixer in any red-blue shell.
The funnel tells a clean story. Of 1108 copies brought to games, 284 were drawn. Of those, 70% reached the battlefield, which is consistent with a land that players play the moment it enters their hand. The median first-cast turn is 4, with the distribution spread across early and mid-game turns, typical of a land that enters when a player needs the colored mana rather than on a strict curve.
The data is well-spread across 454 distinct players, with no single contributor accounting for more than a small fraction of observations. Rootha, Mastering the Moment leads the top commanders list, which is unsurprising given that deck's strict Izzet color identity. Shivan Reef is legal in Commander, Legacy, Modern, Pioneer, Vintage, and most other major formats.

First-cast turn
n=199The "good card" funnel
1108 brought · 454 playersOf 1108 Shivan Reefs brought to games, 284 were drawn and 199 of those were played, with the vast majority staying on the battlefield through the end of the game.
Players who cast this card win 30% of the time (n=196) , vs 24% when it never left the library (n=746).
When players drew this card but left it in hand, they won 33% (n=80) — 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 +6.5pp; 95% confidence interval +0.2pp to +12.9pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
