A cube is Magic as a board game. It’s draft night, but you control the environment. It’s also expensive if you try to do it with only authentic staples.
That’s why a proxy cube is so popular. You get the gameplay you want without needing to treat your collection like a retirement account.
This guide covers the practical side: fairness, readability, sleeves, storage, and how to keep the cube fun instead of fiddly.
Step 1: Decide what your proxy cube is trying to be
Before you print a single card, answer a few questions:
- Do you want high power (fast mana, broken engines) or mid power (more combat, fewer non-games)?
- Do you want it to feel like a specific era (old-school, modern sets, etc.)?
- Is this for experienced drafters or mixed-skill friends?
- How big is the cube going to be?
A common starting size is 360 cards, because it supports an 8-person draft with no leftovers. But you can go bigger if you want more variety.
The main point: pick a direction. Cubes feel bad when they’re a random pile of “good cards” with no structure.
Step 2: Proxy cube fairness is all about consistency
If you want people to trust the draft, the cube has to feel uniform.
Here’s what that means in practice:
Use one sleeve type for the entire cube
Same brand. Same color. Same level of wear.
If some cards feel different, people will notice. Even if nobody accuses anyone of cheating, it still damages trust.
Avoid mixed backs or visible backs
If your sleeves aren’t fully opaque, backs can show. That’s how hidden information leaks happen.
A proxy cube is supposed to be fun. It’s not supposed to be “can you spot the different card through the sleeve under this lamp.”
Standardize your proxies
One consistent layout style beats a mix of styles. A cube draft is fast. People need to parse cards quickly.

Step 3: Readability is the real “power level”
A cube can be balanced on paper and still play badly if the table can’t read the cards.
Here’s the readability standard i like:
The three-second test
Pick up a card and give yourself three seconds. Can you identify:
- Card name
- Mana cost
- Type line
- The main effect (at least the gist)
If not, the proxy design is adding friction to drafting. And friction is the fastest way to turn “fun draft night” into “why did we do this.”
Keep functional zones clean
The art can be stylish. The text box needs to be readable.
In a cube, people are learning the environment while drafting. Don’t make them decode the cards too.
Step 4: Plan your token and double-faced card setup
Token decks and double-faced cards are cube staples now. They’re also where cube nights get messy.
If you want to keep things clean:
- Have a token kit (real tokens or printed proxies)
- Use dice for counts, not identity
- For double-faced cards, use opaque sleeves or placeholders

Step 5: Make setup and teardown easy (or you won’t use the cube)
A cube that takes 45 minutes to set up becomes a cube that lives on a shelf.
Here are two setups that work.
Option A: Shuffle the whole cube, then build packs
- Shuffle everything
- Deal 15-card packs for the draft
- This is the simplest, but shuffling a big cube can take time
Option B: Pre-build packs
- Build packs once, store them as packs
- Draft night becomes grab-and-go
- You’ll need a system for re-packing afterward
Neither is “best.” Pick the one that matches your patience level.
Step 6: Storage that doesn’t make you hate your life
A few boring things make cube ownership way easier:
- Dividers for sections (colors, lands, multicolor, artifacts)
- A separate basics box
- Spare sleeves stored with the cube
- A small token kit stored with the cube
- A note card with your cube’s quick rules (house bans, special archetypes, etc.)
The goal is less searching and more playing.
Step 7: Updating your proxy cube without breaking it
Cubes drift over time. A new archetype gets too strong. One card becomes the obvious first pick every draft. Or your group just gets bored.
A simple maintenance routine:
- After draft night, ask each player: “one card you loved, one card you hated”
- Track the cards that never make main decks
- Make small swaps, then test again
The cube doesn’t need constant changes. It needs thoughtful ones.
Final thought
A proxy cube can be one of the best things you build in Magic. It’s reusable, social, and it turns your favorite parts of the game into a repeatable event.
Just keep it consistent. Keep it readable. Keep it easy to set up.
