Three-color Commander is where decks start feeling “real”… and where mana bases start punishing you for being cute.
You can absolutely build a 3-color deck with the same land count as a 2-color deck. The difference is you’ll lose more games to color screw if your lands aren’t doing their job.
TLDR
For “how many lands in a 3-color commander deck,” start at 37 lands.
Go to 38–40 if you’re running lots of taplands, your curve is higher, or your ramp is light.
35–36 is reasonable for low-curve lists with strong fixing and lots of cheap ramp/draw.
Start here: 37 lands is still the best default
A 3-color mana base doesn’t automatically need more lands than a 2-color mana base. You still want to:
- hit land 3
- hit land 4
- keep making land drops while the table ramps and draws
So the default holds:
- 37 is the “I want to actually play Magic” number
- 38 is the “I’m tired of two-land tragedy” number
The problem usually isn’t total lands. It’s that your 37 lands don’t produce the colors you need on time.

In 3 colors, color fixing matters more than raw land count
This is the big mindset shift:
A 3-color deck can have 37 lands and still be unplayable if too many of those lands:
- enter tapped
- only make one color you don’t need early
- make colorless when your early turns require colored mana
So when you ask “how many lands in a 3-color commander deck,” the honest answer is:
- pick a land count (usually 37)
- then make sure those lands actually cast your spells
A practical way to do this without going full math-mode:
- Look at your early plays (turns 1–3).
- Which color shows up most in those costs?
- Make that color the easiest one to produce early.
If green is your early ramp color, you want green sources early. If blue is your early setup color, you want blue early. This sounds obvious. It’s also the exact thing people skip when they add “fun utility lands” that only tap for colorless.
Taplands: the reason some 3-color decks want 38–40 lands
On a budget, 3-color mana bases often lean on lands that enter tapped. That’s totally fine… but it changes the texture of your deck.
A tapland-heavy deck may want:
- +1 land to reduce the number of hands that are “technically keepable” but too slow
- and/or more ramp so you don’t fall behind while playing lands that can’t be used right away
If your opening turns are frequently:
- tapped land, go
- tapped land, go
- finally an untapped land… and you’re already behind
That’s not a 37-land problem. It’s a speed problem. Adding a land doesn’t fix it by itself, but going from 37 to 38–39 can make your keepable hands less fragile.
Basics vs nonbasics: land count stays similar, but your stability changes
I’m not going to pretend there’s one “correct” number of basics in a 3-color deck. It depends on budget, your ramp, and what your group plays.
But a few things are consistently true:
- More basics usually means fewer awkward early hands (especially on a budget).
- More nonbasics usually means better fixing (if they’re good nonbasics).
- If your ramp searches for basics, you need enough basics to actually find.
So your land count might stay at 37, but your experience changes a lot based on how many of those lands are fetchable basics versus color-fixing dual/tri lands.
And if you’re running MDFCs, you can often keep the land count around 37 while still increasing how often your opening hand has enough mana.
A clean “3-color” land count recommendation
If you want a simple set of targets:
- 37 lands: most 3-color decks, average curve, decent ramp
- 38–40 lands: higher curve, tapland-heavy, or you really want to hit 5–6 mana naturally
- 35–36 lands: low curve + lots of cheap ramp/draw + strong fixing
- 34 and below: usually only if you know exactly why you’re doing it
If you’re unsure, don’t get clever. Start at 37, play games, then adjust.
