Spinerock Knoll is in 4% of tracked Commander decks on Playgroup Live, and 70% of drawn copies are played before the game ends, with a median first-play turn of 4.0.

Spinerock Knoll sits in 4% of tracked Commander decks on Playgroup Live, a niche but consistent presence in red-heavy pods. It appears across 344 of the 8280 distinct decks that have played a tracked game, and the data is well-spread: 313 unique players have brought it to a game, with the single heaviest contributor accounting for just 6% of all tracked instances.

The card's core proposition is a free spell stapled to a tapped red source. Hideaway 4 means you exile one of the top four cards on entry, then unlock it the moment any opponent takes 7 or more damage in a single turn. In red decks built around combat damage, burn, or token swarms, that condition fires reliably enough to matter. 70% of drawn copies are played before the game ends, and 93% of played copies remain on the battlefield at end of game, consistent with a land that simply stays in play until scooped or Strip-Mined.

The commander distribution tells the real story: Valgavoth, Harrower of Souls leads the table by a wide margin, reflecting how well a punishment-damage commander synergizes with a "7 or more damage this turn" trigger. Aggressive mono-red and Rakdos commanders fill out the rest of the list. If your deck regularly threatens large chunks of damage in a single turn, Spinerock Knoll offers a free spell at minimal deckbuilding cost.

≥ -11.0pp

Players who cast this card win 25% of the time (n=110) , vs 28% when it never left the library (n=458).

When players drew this card but left it in hand, they won 33% (n=51) — 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 -2.5pp; 95% confidence interval -11.0pp to +6.0pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Most Spinerock Knolls end the game on the battlefield, as expected for a land. The small library residual reflects the structural reality that most copies of any singleton in a 100-card deck are never drawn in a given game.

Commanders that played this card

in tracked games

Valgavoth, Harrower of Souls dominates the top-commanders chart by deck count, a strong signal that punishment-damage commanders are the primary home for this land. The list fans out across a range of red and Rakdos strategies after that.

Frequently Asked

How often is Spinerock Knoll drawn in a Commander game?

In 681 tracked multiplayer games where Spinerock Knoll was in the deck, it was drawn 24% of the time. That rate is normal for a singleton land in a 100-card deck. Of 171 instances that reached a player's hand, 70% were played before the game ended. The remainder largely reflects games that concluded before the card could be played, not a deliberate decision to hold it.

What turn does Spinerock Knoll typically hit the battlefield?

Median first-play turn is 4.0, with the distribution running from turn 1 through the mid-game. The hand-to-cast data shows a same-turn play rate of 67%, meaning the majority of players who draw it in a given turn put it into play immediately rather than holding it. That makes sense for a land: there is rarely a strategic reason to delay playing it.

Does casting Spinerock Knoll actually help you win?

The current data shows a cast-vs-library delta of -2.5 percentage points, which is a small negative number. Both sample buckets have well over 15 observations, so this is a directional read rather than noise, but the magnitude is modest. A negative delta for a utility land is not unusual. Lands are often run for their secondary ability rather than their direct win contribution, and the free spell from Hideaway may generate value that appears in the commander's win rate rather than the land's.

Is Spinerock Knoll legal in Commander?

Yes, Spinerock Knoll is legal and unrestricted in Commander, as well as in Legacy, Modern, Vintage, and several other formats. It is not legal in Standard, Pioneer, Brawl, or Pauper. The card originally appeared in Lorwyn and has since been reprinted in various Commander products, including the set tracked here: Duskmourn: House of Horror Commander.

Which commanders most often run Spinerock Knoll?

Valgavoth, Harrower of Souls leads the tracked list by a substantial margin. Valgavoth deals damage to opponents as a resource, making the hideaway unlock condition straightforward to trigger. Zada, Hedron Grinder and Krenko, Mob Boss follow, both representing aggressive red strategies where generating 7 damage in a single combat is routine rather than exceptional. The breadth of the list, spanning mono-red, Rakdos, and even a few off-color commanders, suggests the card earns its slot wherever red can reliably spike damage totals.

How concentrated is the Spinerock Knoll data among a few players?

The concentration stats are healthy. 313 distinct players have brought Spinerock Knoll to a tracked game, and the single most active contributor accounts for just 6% of all tracked instances. That is well below the threshold where one player's preferences could meaningfully skew the aggregate numbers, so the draw, cast, and win-rate figures reflect a broad cross-section of play rather than a single prolific contributor.
