Cube Color Balance: Counts That Keep Every Color Open

Cube color balance starts with equal counts, 50 cards per color in a 360-card cube, but equal counts are the beginning of the job, not the end. Two colors can have the same number of cards and wildly different draft value. This article covers the counts that work, the places balance quietly breaks, and the checks that tell you when a color is dead before your drafters start avoiding it.

The goal is not that every color wins the same number of games. It is that a drafter who moves into any color at pick five of pack one can expect a real deck at the end.

What are the standard counts per color?

For a 360-card cube, the common skeleton is 50 cards in each of the five colors, 50 gold, 20 to 30 colorless, and 30 to 40 lands. For 540, scale the colors to about 75 each and the gold to around 75, but grow lands more slowly. Ryan Overturf’s cards-per-color article makes the point that land quality drops off in a bigger cube, so a 540 should not simply run 50 percent more lands.

Those are house guidelines drawn from cubes we draft and the published lists we follow. The MTGO Vintage Cube runs 540 cards and is maintained by Wizards of the Coast, per Draftsim’s overview, and its section counts shift update to update. Equal counts per color are nearly universal; the gold and land numbers are where owners differ.

Why do equal counts still produce unbalanced colors?

Because the count hides three other numbers that matter more.

Depth of the two-drop slot. A color with 50 cards and six playable two-drops is a worse draft color than one with 50 cards and twelve. Count each color’s cards at one and two mana. If any color has fewer than ten, that color struggles to support aggro, and in most cubes that means white or red is quietly weak.

Removal count. A color with no cheap answers is a color nobody wants to be in during game two. Black and red carry removal naturally. White’s removal is often conditional, blue’s is counters and bounce, and green’s is fight spells. If green has two removal-shaped cards and black has twelve, drafters feel it. The numbers to aim for are in how much removal a cube needs.

Role overlap with gold. If six of your ten gold pairs include white, white gets more total draftable cards than blue even with identical mono counts. Check the gold section’s color distribution. Each color should appear in exactly four pairs, so each pair gets the same number of gold cards.

Which colors drift weak, and why?

In our experience and in most published changelogs, two colors need deliberate attention.

Green. Green’s identity in Limited is big creatures and ramp, and cube removal is good enough that big creatures die. Green needs mana creatures that matter, a few card-advantage engines, and either a go-wide plan or a graveyard plan to pair with. If your green section is 30 creatures that cost four or more, it is a trap color.

White. White has the best one-drops in the game and the worst five-drops. Owners who fill white with the same curve as blue end up with weak top end and an aggro plan that runs out of gas. White should run more one- and two-drops than any other color and accept a thin five-plus slot. Our piece on keeping aggro alive explains why this matters for the whole cube.

Blue tends to drift strong, because card draw and counterspells are flexible and every control drafter wants them. Black drifts strong when removal is plentiful. Red is the swing color: strong if the cube supports burn-plus-haste, weak if burn is the only thing red does.

How do you check balance after a draft?

Count four things after every draft and write them on the changelog page.

1. Color pairs drafted. Eight decks, two colors each, sixteen color slots. Over five drafts that is eighty slots, and an even split would give each color sixteen; our house rule of thumb is that a color showing up fewer than ten times in eighty is being avoided.
2. Last-pick colors. Look at what wheeled late. If green cards keep coming around at pick twelve, green is either too deep (good problem) or too weak (bad problem). Ask the drafters which.
3. Match wins by color. Keep it simple: a tally per color per draft night. Over ten nights, the gap between the best and worst color should be modest; a color winning twice as often as another needs a look.
4. Splash rate. If three or four decks splash the same color, that color’s gold or payoff cards are too strong for its mono-colored support. Splashable bombs are a balance leak.

None of these tells you what to change. They tell you where to look. The actual changes follow the method in how to update a cube without breaking it.

Should every color have the same number of creatures?

No. Give the aggressive colors more creatures and the control colors more spells, within a range. A reasonable 360-cube split is 30 to 34 creatures in white and red, 26 to 30 in green and black, and 20 to 24 in blue. The overall ratio is covered in creatures vs spells. Balance is about each color being able to do its job, not about identical pie charts.

What about hybrid and colorless creatures?

Hybrid cards count toward whichever side is weaker when you are balancing, because that is the side that needs them. Treat colorless creatures as a sixth color for counting purposes and keep them modest; a cube where every deck plays the same eight artifact creatures has less color identity, not more.

When should you break equal counts on purpose?

Three cases. A themed cube may deliberately run a short color. A cube whose group refuses to draft a color despite your best efforts can trim it and widen the others. And a cube supporting a specific five-color or four-color archetype can run a slightly larger gold section at the expense of mono counts. In each case, write down the reason in the primer so drafters understand why the packs look the way they do.

For a first cube, do not break equal counts. You will not yet know which imbalances are real and which are one bad night.

FAQ

How many cards per color should a 360 cube have?

Fifty of each color, with about 50 gold, 20 to 30 colorless, and 30 to 40 lands. Those are house guidelines; equal counts per color are the near-universal part.

Which color is usually weakest in a cube?

Green, in most unthemed cubes, because its big creatures run into plentiful removal. White is the other common weak spot when its curve is built like blue’s instead of leaning on one- and two-drops.

How do you know if a color is underpowered?

Track color pairs drafted, which colors wheel late, and match wins by color over several drafts. One bad night means nothing; a color avoided across five drafts does.

Does the gold section affect color balance?

Yes. Each color should appear in the same number of gold cards, usually four pairs times five cards each in a 360 cube. Uneven gold counts give some colors more draftable cards than others.

Count more than cards

Equal counts get you to the table. Counting curves, removal, and what wheels keeps every color worth drafting. The game is the reason. The people are the point.
