Shivan Reef
Shivan Reef appears in 8.7% of tracked Commander decks on Playgroup Live. When drawn, it's cast 70% of the time, and 95% of cast copies are still on the battlefield when the game ends.
Shivan Reef is a staple dual land for any Commander deck running both blue and red. Across 214 tracked games on Playgroup Live, it appears in 147 distinct decks, good for an 8.7% inclusion rate across all decks in the dataset. That number reflects the format constraint: Shivan Reef is only eligible in decks with both {U} and {R} in their color identity, so the real penetration within that subset is considerably higher.
70% of drawn copies are cast before the game ends, a strong draw-to-play rate for a land that enters tapped in zero ways and has zero setup cost. The median first-cast turn is 5, though the distribution spans turns 1 through 12. 50% of drawn copies are cast the same turn they're drawn, consistent with players immediately dropping a land into play rather than holding it. Once it resolves, it sticks: 95% battlefield stickiness is about as permanent as a permanent gets.
Win rate when cast sits at 44.7% versus 38.8% when it sits in the library all game, a directional positive delta of +5.9 points. Both sample sizes exceed 15 observations, so this signal is worth noting, though the dataset is still growing and the gap should be treated as directional rather than conclusive.

How often is Shivan Reef drawn in a Commander game? ▾
Across 214 tracked games, Shivan Reef was drawn in 22.5% of deck-participations where it was included. That is typical for a singleton in a 100-card deck. Of the 54 instances we observed entering a player's hand, 38 were cast before the game ended, giving a 70% draw-to-play rate.
What turn does Shivan Reef usually get played? ▾
Median first-cast turn is 5, with the middle 50% of casts landing between turns 3 and 6. Four copies were played on turn 1, suggesting those hit opening hands. The distribution is relatively flat from turns 2 through 7, which reflects when players naturally hit their land drops rather than any strategic decision to hold the card.
Does casting Shivan Reef correlate with winning? ▾
Early data shows a +5.9 percentage point win rate delta between games where Shivan Reef was cast (44.7%, n=38) and games where it sat in the library the whole time (38.8%, n=183). Both buckets exceed 15 observations, so this is a meaningful directional signal, but the overall dataset is still growing. Treat the gap as consistent rather than definitive.
Why is Shivan Reef played over a basic Island or Mountain? ▾
Shivan Reef taps for either {U} or {R} with no enters-tapped downside, at the cost of 1 life per colored mana. In Commander, where players start at 40 life, that 1 damage is rarely relevant. The ability to produce either color flexibly in a two-color deck is worth far more than the life loss in the vast majority of game states.
Which commanders most often run Shivan Reef? ▾
The top two commanders in the dataset are Rootha, Mastering the Moment (23 decks) and Galazeth Prismari (22 decks), both strict Izzet ({U}{R}) commanders. Magnus the Red follows at 14 decks. The heavy concentration among pure Izzet commanders makes sense: decks with a third or fourth color have additional dual land options to fill, while two-color decks lean harder on reliable Izzet duals.
Is Shivan Reef legal in all Commander formats? ▾
Shivan Reef is legal in Commander, Duel Commander, Oathbreaker, Brawl, and most other competitive formats including Legacy, Modern, Pioneer, and Vintage. It is not legal in Standard, Alchemy, or Pauper. There are no current bans or restrictions on the card in any format where it is legal.
