13% of tracked Black-Red Commander decks run Canyon Slough, and when a copy reaches a player's hand, it is played 66% of the time with a median first-cast turn of 3.0.

Canyon Slough occupies a reliable niche in Black-Red mana bases. Across 896 tracked multiplayer Commander games, 13% of decks bring it to the table, with 523 of the 3886 distinct tracked decks running a copy.

The card's core appeal is flexibility. It enters tapped, so it costs tempo on the turn it's played. In exchange, it counts as both a Swamp and a Mountain for color requirements, and its cycling ability means it can convert into a fresh card for two mana when the land is not needed. That dual role shows up in the data: a median first-cast turn of 3.0 reflects a large cluster of copies played early as a land, alongside others held and cycled or played much later. 66% of drawn copies are played before the game ends, a neutral figure that reflects both early land drops and late cycling decisions.

Commander decks with Blue in their color identity, particularly those led by Doctor Doom, King of Latveria, account for a notable share of Canyon Slough's presence in tracked games. The card's spread across 447 unique players and a single-player max contribution of 2% of instances signals that what we see is not driven by one prolific contributor. It is an early, broadly sourced signal.

≥ -3.1pp

Players who cast this card win 25% of the time (n=157) , vs 21% when it never left the library (n=588).

When players drew this card but left it in hand, they won 20% (n=75) — 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 +3.9pp; 95% confidence interval -3.1pp to +10.9pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Most tracked Canyon Slough copies finish on the battlefield or in the graveyard, with very few stranded in the library. That graveyard share is a consistent, if directional, sign that the cycling ability sees real use.

Doctor Doom, King of Latveria leads by raw deck count, but the commander list spans multiple color combinations. Any deck with both Black and Red is a potential home, and that breadth shows clearly here.

Frequently Asked

How often is Canyon Slough drawn in a Commander game?
Across 896 tracked multiplayer games where Canyon Slough was in the deck, it was drawn 27% of the time. That is consistent with expectations for a singleton in a 100-card deck. Of 254 total drawn instances, 66% reached play before the game concluded.
What turn does Canyon Slough typically hit the battlefield?
The median first-cast turn is 3.0, but the distribution is spread wide. A large cluster of copies is played on turn 1 when drawn in the opening hand as an early land drop. Many others are played later or cycled away for a card. The mean sits closer to turn 4, reflecting that later-game copies see more varied treatment.
Is Canyon Slough ever cycled rather than played as a land?
The graveyard is the second most common final zone for Canyon Slough in tracked games, and the hand-to-cast data shows copies sometimes sit in hand for several turns before being acted on. This is consistent with players holding the card and cycling it for two mana rather than playing it as a tapped land. The data does not separate cycle events from other discards, but the graveyard finish rate is a directional indicator that cycling happens in meaningful proportion of cases.
Does casting Canyon Slough correlate with winning?
Win rate when the card is cast is 25% across 157 participations, compared to 21% across 588 participations where it stayed in the library. The raw delta is small and the confidence interval crosses zero, so treat this as a directional early signal rather than a firm conclusion. Sample sizes here are growing but not yet large enough to call the effect definitive.
Which commanders most commonly run Canyon Slough?
Doctor Doom, King of Latveria leads the tracked list by deck count, followed by Auntie Ool, Cursewretch and Valgavoth, Harrower of Souls. The top commanders span Black-Red, Grixis (Black-Red-Blue), and Jund (Black-Red-Green) color identities, which matches Canyon Slough's role as a dual land for any deck touching both Black and Red.
Is Canyon Slough legal in Commander and other formats?
Canyon Slough is legal in Commander, Legacy, Modern, Pioneer, Vintage, Historic, Timeless, and several Brawl variants. It is not legal in Standard, Pauper, or Pauper Commander. There are no bans or restrictions in any format where it is currently legal.
