How Many Lands Should a Commander Deck Play? The Definitive Guide

The most common question in Commander isn't about combos or win conditions. It's about something far more fundamental: how many lands should your deck play? The answer isn't a single number. It depends on your deck's strategy, your mana curve, and how much ramp you're running. In this guide, we'll break down the math and give you practical land counts for every archetype.

The Baseline: 36-38 Lands

For a typical Commander deck with an average mana value of 3.0-3.5 and 10-12 pieces of ramp, the sweet spot is 36-38 lands. This gives you a 90-95% chance of hitting your third land drop by turn 3, which is critical for staying competitive at the table. If you're running heavy ramp (15+ pieces), you can drop to 34-36 lands. If you're running light ramp (under 8 pieces), you need 38-40 lands.

Adjusting for Mana Curve

Your average mana value (MV) is the single biggest factor in determining land count. Decks with a low average MV (2.0-2.5) can afford to run fewer lands because they can play meaningful spells earlier. Decks with a high average MV (4.0+) need more lands to ensure they can cast their expensive spells on time.

• Average MV 2.0-2.5: 34-36 lands. These decks can play 1- and 2-drops consistently, so they don't need as many lands to function.
• Average MV 2.6-3.2: 36-38 lands. The standard range for most Commander decks.
• Average MV 3.3-3.8: 38-40 lands. You need more lands to hit your 4- and 5-drops on curve.
• Average MV 4.0+: 40-42 lands. High-curve decks need maximum lands to function. Consider adding more ramp or cutting expensive spells.

How Ramp Affects Land Count

Ramp effectively replaces lands. Every piece of ramp you run is one fewer land you need. But not all ramp is created equal. Mana rocks like Sol Ring and Signets produce mana immediately, while land-based ramp like Cultivate and Farseek take time to set up. Here's how to adjust:

• 0-5 ramp: Add 2-4 lands to your baseline.
• 6-10 ramp: Standard land count (36-38).
• 11-15 ramp: Subtract 2 lands from your baseline.
• 16+ ramp: Subtract 4 lands. You're running so much ramp that you can afford to run fewer lands.

Archetype-Specific Land Counts

Different deck archetypes have different land requirements. Here's a breakdown by strategy:

• Aggro: 34-36 lands. You want to play cheap creatures and overwhelm opponents quickly. Every land beyond 36 is a potential brick.
• Midrange: 36-38 lands. The standard range. You need enough lands to play your 3- and 4-drops but not so many that you flood.
• Control: 38-40 lands. You need to hit your land drops to play counterspells and board wipes. Control decks can afford to run more lands because they have card draw to compensate.
• Combo: 34-38 lands. Combo decks need to find their pieces quickly, so they often run less ramp and more lands. The exact count depends on your combo's mana requirements.
• Stax: 38-40 lands. Stax decks need to play their pieces early and consistently. More lands means more consistency.

The Math Behind Land Drops

If you're curious about the probability of hitting your land drops, here's the math. With 36 lands in a 99-card deck, your chance of having exactly 3 lands by turn 3 is about 60%. Your chance of having at least 3 lands is about 90%. If you drop to 34 lands, your chance of hitting 3 lands drops to about 85%. That 5% difference can be the difference between winning and losing.

The key insight is that missing a land drop is exponentially more punishing as the game goes on. Missing turn 1 is bad. Missing turn 2 is worse. Missing turn 3 is often game-losing. This is why we prioritize hitting our early land drops over having extra lands in the late game.

Common Mistakes

Here are the most common land count mistakes we see in deck analysis:

• Running 32 lands with no ramp: You will miss land drops and lose games you should win.
• Running 40 lands with 15 ramp: You'll flood out and draw lands you don't need.
• Ignoring mana curve: A deck with a 4.0 average MV needs more lands than a deck with a 2.5 average MV, even if they run the same amount of ramp.
• Not counting mana dorks as ramp: Creatures like Llanowar Elves and Birds of Paradise are ramp. Count them when calculating your land count.

Using Rate My Decks to Check Your Land Count

When you analyze your deck with Rate My Decks, we calculate your average mana value, ramp count, and land count. If your land count is outside the optimal range for your deck's profile, we'll flag it as a weakness and recommend adjustments.
