Cube Card Selection: Power, Role, and Fun

Cube card selection comes down to three questions asked of every card: Is it strong enough for this cube? What job does it do in a deck? Is it fun to have across the table? A card that passes all three goes in. A card that passes only the first one is how cubes end up as a pile of staples that nobody enjoys drafting.

This is a method for filling a slot when one opens up, and it is the one we would recommend to anyone building a first list. It assumes you already know the basics of building a cube and want to get better at the choosing part.

What power level is your cube?

Decide this first, because every other decision depends on it. Power level is not “how expensive are the cards” but “what is the ceiling of what a deck can do on turn three.”

A rough spectrum:

• Pauper. Commons only. Turn three is a 2/2 and a removal spell. Games go long and combat matters.
• Peasant. Commons and uncommons. Adds cards like Lightning Helix and Mulldrifter without the rares that end games alone.
• Legacy or “unpowered.” Everything but the Power Nine and the most broken fast mana. Turn three can be Jace, the Mind Sculptor or a reanimated Griselbrand.
• Vintage or “powered.” Black Lotus, the Moxen, Sol Ring, Mana Drain. Turn one can be a planeswalker.

Within each band, the goal is a flat power curve. You want the median card and the best card to be close enough that a drafter who misses the three best cards in a pack still gets a good deck. A pauper cube with one accidental rare in it is a cube with a lottery ticket. A pauper table and a vintage table feel like different games, and both are good ones.

Once you pick a band, write it down. Every card you consider gets measured against the band, not against the best card ever printed.

What role does the card fill?

Here is where most first cubes go wrong. The builder opens a list of the top 360 cards for a power level and copies it. The result has 14 counterspells, 3 one-drop creatures, and a Golgari section that is just good black cards and good green cards sitting next to each other.

Instead, think in slots. Each color in a 360-card cube gets roughly 50 slots. Before you pick a single card, sketch what those 50 need to be. For white, that might be:

• 9 one-drop creatures
• 10 two-drop creatures
• 7 three-drops
• 5 four-drops and up
• 8 removal spells
• 4 token makers or anthems
• 4 planeswalkers or card-advantage pieces
• 3 flexible slots

Now each card competes only against cards for the same slot. Savannah Lions competes with Thraben Inspector and Kytheon, not with Swords to Plowshares. That is a fair fight, and it lets you say “this is the eighth-best white one-drop, and I need nine, so it is in.”

A role-first list also exposes gaps you cannot see any other way. If your black section has 11 removal spells and 2 sacrifice outlets, your Rakdos sacrifice lane is not real, no matter how good the individual cards are. See cube archetypes explained for the counts each lane needs.

The question to ask is not “is this card good?” It is “which of my decks wants this card, and what does it replace?”

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

Is the card fun to play against?

Power and role are measurable. Fun is a judgment, and it is the one that separates cubes people love from cubes people tolerate.

A few patterns that test badly at a weekly table:

Cards that end the game without a game. Turn-two Blood Moon against a two-color deck. Armageddon when the other player is ahead on board. Winter Orb. Powerful, historically important, and reliably the reason someone leaves early. Many cubes cut land destruction and resource denial entirely, not because they are weak but because a loss to them teaches the loser nothing.

Cards that take five minutes a turn. Sensei’s Divining Top in a Swiss round with a clock. Some storm pieces. Anything that makes one player shuffle while seven people wait.

Cards that only matter if you already know the cube. A narrow combo piece that is a blank to a new drafter and a free win to a regular. These are fine in a cube for eight veterans and bad in a cube that welcomes new people.

Cards that are miserable in multiples. One Stoneforge Mystic is a card. Two in the same deck is a problem, and three sword-style equipment in a 360 cube means someone has that deck every week.

None of these are rules. Some groups love a Blood Moon. The point is to decide on purpose. Write down what your cube does not do, and check each candidate against the list.

A scoring method you can actually use

When a slot opens, we rate each candidate on three scales and add them up. It is crude and it works.

A card scoring 7 or higher goes in. A 6 goes on the watch list. Anything with a 1 in any column gets a hard look, because a 3-3-1 is usually a mistake: a powerful, needed card that makes the night worse.

Try it on real candidates. Lightning Bolt is 3-3-3 in any red section; it is efficient, red always needs cheap removal, and nobody minds losing a creature to it. Balance might be 3-2-1: powerful, fills a sweeper slot, and ends games in a way that feels arbitrary. Mulldrifter in a peasant cube is 3-3-3. The same card in a powered cube might be 1-2-3: too slow, but still beloved.

Where do you find candidates?

Three sources, in order of usefulness:

1. Other cubes. CubeCobra lets you filter thousands of public lists by power band and see what shows up most. The most-included cards for a band are a starting point, not a finish.
2. Your own draft notes. After each night, write down which cards were last-picked, which were never cast, and which decks wished for something they could not find. Three weeks of notes beats any outside list.
3. New sets, filtered hard. Every set has two or three cube-worthy cards and a hundred that look like it. Wait a month and watch what the public lists actually add.

Avoid picking cards because they are famous. Many cards that defined Standard are mediocre in a forty-card deck against a curve of two-drops. Many cards nobody remembers are cube all-stars because their role is so clean.

FAQ

How many cards should a first cube have?

360 cards supports eight players drafting three packs of fifteen. That is the standard first size. You can always grow it to 450 or 540 later.

Should a first cube include expensive cards?

No. Pick a power band you can afford to complete, and consider proxies for the few expensive cards that define a slot. Most casual groups are fine with a few clearly marked proxies.

What is the biggest mistake in choosing cube cards?

Copying a staples list without planning slots. The cards are all good and the decks do not work.

How do you know when to cut a card?

When it is picked late three drafts running, or when it is picked early and never cast. Either way, the slot is not earning its place.

The list is a draft of your group

A cube list is never finished, and it should not be. It is a running argument between what is powerful and what makes eight people glad they came out. Choose for the table in front of you. The game is the reason. The people are the point.
