A good MTG cube is not just a pile of powerful cards.
That is the first trap.
A cube can be packed with iconic spells, efficient creatures, premium removal, and old favorites, and still produce boring drafts if the environment does not have shape. The best cubes feel intentional. They create decisions. They support different strategies. They make players argue over picks in a good way.
A cube should make people say, “Run it back.”
Decide What Kind of Cube You Are Building
Before choosing cards, decide what experience you want.
Do you want a high-powered vintage-style cube? A budget cube? A peasant cube? A tribal cube? A graveyard cube? A cube based around combat? A cube that feels like older Magic? A cube that supports newer mechanics?
There is no correct answer. But there should be an answer.
A cube without a clear identity can become muddy. Aggro cards do not have enough support. Control decks get too much removal. Combo pieces show up without payoff. Midrange becomes the only real option, which is fine for some people but can get repetitive fast.
The clearer your cube identity, the easier it is to make cuts.
Support Aggro Properly
Many cube designers accidentally make aggro bad.
They include flashy late-game cards, sweet value engines, and expensive planeswalkers, then wonder why every draft turns into a midrange soup festival.
Aggro needs real support. That means enough one-drops, enough cheap interaction, enough reach, and enough reasons to punish slow decks.
If aggressive decks cannot win, the whole environment slows down. Control and midrange players get too comfortable. Games go long. Drafts become predictable.
Good aggro makes everyone honest.
Give Each Color a Job
Colors should have identities. That does not mean they need to be narrow, but they should feel distinct.
White might support go-wide creatures, blink, and removal. Blue might support tempo, control, and spells. Black might support sacrifice, reanimator, and attrition. Red might support aggro, burn, and artifacts. Green might support ramp, counters, and big creatures.
Once each color has a role, multicolor pairs become easier to define.
For example:
White-blue: blink or control
Blue-black: reanimator or tempo
Black-red: sacrifice or aggressive removal
Red-green: stompy or lands
Green-white: tokens or counters
These archetypes help drafters understand what is open. They also make the draft feel less random.
Do Not Overload on Cute Cards
Every cube designer has pet cards. That is fine.
The danger is when too many pet cards sneak in without doing enough work. A card can be nostalgic, funny, or flavorful and still be wrong for the environment.
Ask hard questions:
Does this card support an archetype?
Is it playable in more than one deck?
Is it too weak for the cube’s power level?
Is it too strong and repetitive?
Does it create fun decisions?
Does anyone actually draft it?
If a card keeps wheeling and never makes main decks, it may be time to let it go. Place it gently in the binder. Thank it for its service.
Use Proxies to Test Expensive Cards
Cube can get expensive quickly. Dual lands, premium staples, powerful artifacts, and older cards can turn a casual project into a financial event.
Proxies are extremely useful for cube testing. They let you try cards before buying them, protect valuable originals, or build a cube environment that would otherwise be out of reach.
For clean testing copies, PrintMTG is a useful resource for casual MTG proxy cards. Just keep proxies clearly identified and use them in playgroups where everyone is comfortable with them.
On a research-focused site like Overvalwagen, detail matters. Cube design is similar. The small choices, the card slots, the balance between themes, all of that shapes the final experience.
Watch the Draft, Not Just the Games
Playtesting a cube is not only about who wins.
Watch the draft itself.
Are players finding clear lanes? Are certain archetypes always open because nobody wants them? Are some colors overdrafted because they are obviously stronger? Are narrow cards trapping people? Are gold cards too hard to cast? Are mana fixing and lands showing up at the right rate?
A cube can produce fun games but frustrating drafts. The draft is half the experience, so treat it that way.
Keep Updating
A cube is never truly finished. That is part of the fun.
New sets bring new tools. Old cards become more interesting when support improves. Some cards get stale. Some archetypes need help. Some cards turn out to be miserable and should be removed before they ruin another evening.
Small updates keep the cube alive.
But do not change too much at once. If you swap twenty cards after every draft, it becomes hard to know what improved and what got worse. Make focused changes, test, then adjust again.
The Best Cube Is the One People Request
A good cube is not measured only by power level or price. It is measured by whether people want to draft it again.
If players leave talking about their decks, the close games, the weird picks, and the card they should have taken, the cube is working.
Build with intention. Support your archetypes. Protect the fun. Cut cards that do not belong.
And remember: if every deck becomes five-color good stuff, something has gone wrong. Unless that was the plan, in which case, congratulations on building chaos with lands.
