A lot of people build Commander decks from the spell pile backward.
They start with the commander, add the synergy cards, add the pet cards, add the staples, add the spicy nonsense, and then look down at the deck and realize they only have room left for 34 lands. So 34 it is. Maybe 35 if they feel responsible that day.
That is usually backwards.
Your mana base is not the boring tax you pay before you get to play Magic. It is the thing that lets the rest of the deck function. If you miss early land drops, the whole deck slows down. If you are playing three colors on a budget, the problem gets worse. If your commander costs five or six mana, it gets worse again. And if half your lands enter tapped, now you are also paying a tempo tax for the privilege of being behind.
Kraken Opus already has a strong companion piece on Commander ramp and another on why too many taplands quietly cost games. This land count question sits right between those two topics. It is the missing middle. Ramp cannot fully rescue a greedy land count, and a pile of taplands can make an okay land count feel bad anyway.
How many lands in Commander should most decks start with?
For most normal Commander decks, the best starting point is 37 or 38 lands.
That is not a law. It is a baseline. But it is a good baseline because it gives you enough natural land drops to actually play the game while still leaving room for ramp, draw, removal, and the cards you are excited about.
Here is the version i would actually use:
- 37 to 38 lands for most midrange Commander decks
- 39 to 40 lands if your commander is expensive, your curve is clunky, your mana is budget and slow, or your deck really needs to hit land drops every turn
- 34 to 36 lands only if you have a genuinely low curve, lots of cheap reliable ramp, strong card flow, and a real reason to be that lean
That last category is where people get in trouble. They think their deck is low curve because it has a few one and two drops, but then the deck still has a pile of fours, fives, and sixes. Or they think they can cut lands because they run ten ramp cards, but half the ramp starts at three mana. That is not the same thing.
If you want a practical shortcut, ask this: what happens if you miss your third land drop? If the answer is “not much,” your deck can probably get away with a leaner count. If the answer is “i do nothing and look embarrassed,” you need more lands.
Your commander and your curve matter more than your ego
Your commander is a big clue.
A two mana commander with a low curve and lots of cheap cantrips can often live with fewer lands than a six mana commander that wants to untap and dominate the board. That sounds obvious, but people ignore it all the time because the decklist looks cleaner with more action cards.
Your curve tells the real story, though.
If your deck is packed with two and three drops, you can sometimes get a little greedier. If your deck lives in the four to six mana range, you want a sturdier land count. And if your deck is full of expensive haymakers, X spells, or mana sinks, you should probably stop flirting with 35 lands like it is some clever secret.
I believe this is the simplest way to think about it:
A low curve deck wants to start playing early and double spell fast. A midrange deck wants to hit four and five mana on time. A high curve deck wants enough lands that it can still function when the first ramp piece gets removed. Those are not the same jobs, so they should not all use the same land count.
Cheap ramp changes the math, but not as much as people want
Yes, ramp matters. But it matters differently depending on the kind of ramp.
Cheap, reliable ramp can let you trim lands a bit. The key words there are cheap and reliable.
A two mana signet, Nature’s Lore, Farseek, Arcane Signet, a one mana mana dork in the right shell, those are the cards that actually change your early mana pattern. They show up on time and help you bridge into the rest of your deck.
Three mana ramp is still good. But three mana ramp usually does not justify slashing lands. If you miss early land drops, you might not cast your three mana ramp spell on time anyway. That is the problem.
This is why the greediest decks often fail in such a specific way. They cut lands because they “have ramp,” but the ramp only works if the lands show up first.
A practical rule is to be conservative. If your deck has a healthy number of cheap ramp pieces, you can trim a land or two from an otherwise sane baseline. But i would not use ramp as an excuse to turn 38 into 33 unless the whole deck is built for that life.
Taplands, utility lands, and color needs quietly change the answer
One thing people miss when asking how many lands in Commander is that not all lands do the same job.
A three color deck with a bunch of slow duals is not functioning like a smooth two color deck with a pile of untapped lands. A deck with eight utility lands is not functioning like a deck with mostly clean colored sources. A mono color deck can cheat in ways a budget three color deck cannot.
That means your raw land count and your effective land count are not always the same.
If you are playing more colors, especially on a budget, you usually want a little more land, not less. And if you are stuffing the deck with cute utility lands, be honest about what they cost. Rogue’s Passage is great. War Room is great. Field of the Dead is very great. But colorless utility lands still make color requirements harder, especially in decks with early double pips.
The same goes for too many taplands. If your lands keep entering tapped, you might technically be making land drops and still feel behind. That is one reason some decks feel awkward even when the count looks normal on paper.
A little raw deck math shows why small changes matter
This part is not glamorous, but it matters.
If you compare raw 99 card math, moving from 34 lands to 37 lands gives you a noticeable bump in your odds of naturally seeing four lands in your first 11 cards. Push from 37 to 40 and it climbs again. These are not tiny fake improvements. They are real enough that you feel them in actual games.
And that is the whole point. Commander is full of advice that sounds dramatic but barely changes outcomes. Land count is not like that. A difference of two or three lands really can change how often your deck gets to function.
That does not mean every deck should jam 40 and call it a day. It means shaving lands has a cost, and the cost is real.
When can you safely go lower on how many lands in Commander?
You can go lower when several things are true at once, not just one.
Maybe your commander costs two. Maybe the curve is genuinely low. Maybe you run a lot of cheap cantrips, cheap rocks, cheap land ramp, and modal cards that reduce flood risk. Maybe your deck is built to operate cleanly on two and three mana for the first several turns. Maybe your table is faster and you care more about explosive early sequencing than long-game stability.
That is how 34 to 36 lands starts to make sense.
But most casual Commander decks do not check enough of those boxes. They just want to.
If your deck is full of four drops, your commander costs five, and your first real ramp spell costs three, cutting to 35 lands is usually not “tight deckbuilding.” It is optimism wearing a fake mustache.
Signs your land count is still wrong
You usually do not need a spreadsheet to catch this. The games tell you.
If any of this sounds familiar, the land count probably needs work:
- You keep opening hands that look technically playable but stall immediately
- You miss your third land drop often enough that your group jokes about it
- You cannot cast your commander on time in a deck built around that commander
- Your ramp spells keep fixing problems that lands should have solved
- Your hand has spells, but your board has nothing going on
And on the other side, be careful not to overreact to one flood game. Flood happens. The better question is what your deck does with extra mana. Many decks should add more draw, more mana sinks, or better card quality before they cut lands.
The clean recommendation
So, how many lands in Commander should you play?
Start with 37 or 38 if you want the short answer.
Move to 39 or 40 if your commander is expensive, your curve is heavy, your mana base is slower, or you just want your deck to function more often.
Only drop to 34 through 36 when your deck has the speed, ramp, and card flow to support it, and when you are doing it on purpose instead of because you got greedy while cutting cards.
That is the real trick. Make the number a deckbuilding choice, not the leftover result of trying to keep too many spells. Lands are not exciting. But neither is spending half the game doing nothing.
