How to Read a Cube List in Ten Minutes

Learning to read a cube list is the fastest way to get better at building one. A list is 360 to 600 card names, and a new cube owner usually reads it the wrong way: scanning for the cards they recognize and judging the cube by whether it has their favorites. A designer reads it the way a chef reads a menu, for structure first and ingredients second.

This is a ten-minute method, in order, with two public lists as worked examples: the MTGO Vintage Cube and the MTGO Legacy Cube. You can run it on any CubeCobra page, and on your own cube, which is the real reason to learn it.

Step 1: Count the sections before you read a single card

Every cube list breaks into sections: the five colors, gold, colorless, lands. The counts tell you what the designer values before you know anything else.

Read the Vintage column and you learn three things without opening a card: blue is the best color by design (80 against 56 for green), the gold section is large (about a quarter of the cube), and artifacts matter (69 colorless cards, which include Sol Ring, Mana Crypt, Black Lotus and the colorless lands). Read the Legacy column and you learn the opposite: colors are nearly even, gold is narrow at six per guild, and lands are tracked separately.

Those are two different design philosophies, and you found them in sixty seconds. If a list does not label its sections, CubeCobra’s analysis tab will count them for you.

Step 2: Find the curve in one color

Pick one color, usually white or red because aggro lives there, and sort by mana value. You are looking for the shape.

• A cube that wants aggro to work will have a thick band of one- and two-drops in white and red, often a third of the color or more. The Pauper Cube’s own guide notes that about a third of its white creatures cost two or less.
• A cube that is secretly midrange will have most of its creatures at three and four, with a handful of two-drops that are really utility cards (a Stoneforge Mystic, a Thalia) rather than attackers.
• A cube that leans control will show card draw and removal at two and three, finishers at five-plus, and very few creatures under three that attack well.

You do not need to count precisely. Scroll the sorted list and notice where the pile gets thick. Then check whether the primer’s description of the cube matches what you see. When it does not, trust the list. Our article on the cube mana curve explains what each shape does to game length.

Step 3: Count the fixing

Lands are the most under-counted section in cube design, and Lucky Paper’s 2022 study of more than 75,000 draft decks found most cubes run about 8% to 12% fixing when it suggested 28% to 39% to match the fixing of two-color Legacy or Modern Constructed decks. So count.

Add up every nonbasic land that produces two or more colors, plus any Signets, Talismans and Arcane Signets if the cube uses rocks as fixing. Divide by the cube size. Then ask:

• Under 10%: decks will be two colors and tight. Splashing is a mistake. Aggro gets a boost because mana is honest.
• 10% to 20%: two colors plus a light splash. The most common range in paper cubes.
• Over 25%: three-color decks are normal and the cube is probably built for a slower, bigger game. The Chromatic Cube on Arena is built for multicolor, high-curve decks on purpose.

Also note what kind. Fetches and duals mean fixing is untapped and fast. Gain-lands and bounce-lands mean the cube is deliberately taxing the greedy player. Cube mana fixing covers the trade.

Step 4: Find the gold section’s job

Gold cards are the designer talking to you directly. Each two-color card is a sentence about what that pair is supposed to do.

Read all of one guild. If Boros is Lightning Helix, Figure of Destiny and Boros Charm, the pair is aggro and the designer expects you to know that. If Boros is Ajani Vengeant and Deafening Clarion, it is a control pair in this cube, which is unusual and worth remembering. If Boros is three cards that have nothing to do with each other, the designer has not decided, and that guild will be the weakest lane at the table.

The size of the section is its own signal. Six per guild, as in the Legacy Cube, says “the pairs are hints.” Fifteen per guild, as in the Vintage Cube’s Izzet, says “this pair is a full archetype with its own payoffs.”

If this is useful, the newsletter sends more like it.

Step 5: Look for the packages

The best modern cube lists are built in packages: a build-around plus the four to eight cards that make it work. When the August 2026 update brought Dark Depths back to the Vintage Cube, it came with Crop Rotation, Sowing Mycospawn, Knight of the Reliquary and Wight of the Reliquary, alongside the Thespian’s Stage already in the list. That is a package. Dark Depths alone would be a trap.

So when you see a build-around (Recurring Nightmare, Sneak Attack, Oath of Druids, Tinker, Splinter Twin), scan for its friends. Count them. A build-around with one supporting card is a card the designer likes. A build-around with six is an archetype the designer supports. The second kind is what you should draft toward, and what you should emulate when you add a theme to your own cube.

The inverse check: find a card that looks out of place, a Goblin Bombardment in a cube with no tokens, say, and ask what package it belongs to. Usually it is a leftover from a theme that got cut. That is a slot the owner has not noticed is dead.

Step 6: Read the exclusions

What a list leaves out is as loud as what it includes, especially in high-power cubes.

Ryan Overturf’s May 2021 read of the Legacy Cube noticed the absences first: no Mana Drain, no Strip Mine, no Prismatic Vista, and no Signets or Talismans at all. From those absences he predicted mono-blue would be harder and Armageddon better.

For an unpowered paper cube, the exclusions to check are: Sol Ring and Mana Crypt (is fast mana allowed at all?), Oko and the strongest planeswalkers (is the owner policing swingy cards?), free counterspells (is tempo-blue meant to be a top deck?), and Armageddon or Balance (is the owner comfortable with games that end abruptly?). Each answer places the cube on a map, and cards too strong for an unpowered cube has the longer list.

Step 7: Only now, read the cards

With the structure in your head, scan the full list. You are no longer asking “does it have my favorites?” You are asking:

• Which lane would I draft on this list, and is it well supported?
• Which lane looks under-supported, and is that a gap or a choice?
• Which three cards surprise me, and what package are they in?
• What is the single card I would cut, and what would I replace it with?

Write those four answers down. If you are reading a friend’s list, that is useful feedback. If you are reading your own, it is next month’s changelog.

A note on primers

If the list has a primer, read it after the list, not before. A primer tells you what the designer intended. The list tells you what they built. The gap between the two is where the useful conversation is, and reading the primer first makes you see the list through its claims.

FAQ

What should I look at first in a cube list?

Section counts. The number of cards per color, in gold, in colorless and in lands tells you the designer’s priorities before you read any card.

How do I tell what archetypes a cube supports?

Read each guild’s gold cards as a sentence, then look for build-arounds with four or more supporting cards. Lanes with a clear gold signpost and a full package are the supported ones.

How much fixing is normal in a cube?

Lucky Paper’s CubeCobra data put most cubes at about 8% to 12% of the list, and argued that matching the fixing of two-color Legacy or Modern Constructed decks takes substantially more.

Should I read the primer or the list first?

The list. The primer tells you intent; the list tells you what was built. Compare the two afterward.

Bring a list to the table

Reading lists is a skill that gets faster with practice, and the best practice is reading one with the person who built it sitting across from you. Swap lists with friends and read them out loud together.
