MTG Proxy Cube Guide: Build a $10,000 Cube for Under $150
Building an MTG proxy cube is the single best value in all of Magic: The Gathering. A cube is a curated, self-contained draft environment — hundreds of cards you own, shuffled into packs, and drafted like a booster draft with no packs to buy. The catch? A powered cube with Black Lotus, the Moxen, and the rest of the Power Nine runs $10,000 to $30,000+ in real cards. A fully proxied version of the exact same list costs about $216 for 360 cards — and a 180-card starter cube for game night costs just $126. If you’ve never drafted a Cube Cobra list, or you’re looking for the cheapest way to draft the most powerful cards in Magic history, this guide walks you through everything: what a cube is, what it really costs, how to build a proxy cube step by step, and how to sleeve and run it like a veteran.
Cube is the format where proxies are not just accepted — they’re the norm. Unlike competitive formats with official ban lists and sanctioned events, a cube is your own personal card pool. Nobody polices it, nobody certifies it, and the community has been proxying cube staples for well over a decade. That’s why this guide focuses on the numbers, the card choices, and the practical build steps — so you can draft a $10,000 cube for less than the price of a video game.

Quick Facts
Why Cube Is the Best Format for Proxies
If you’ve only played constructed formats, cube might sound unfamiliar. Here’s the pitch: instead of bringing a pre-built deck, every player at the table drafts one on the spot from a shared card pool — the cube. The cube owner designs that pool: the color balance, the archetypes, the power level, even the theme. That makes cube the ultimate expression of Magic’s core mechanic, and it explains why so many veteran players call it “the best format.”
Three things make cube uniquely suited to proxies:
It’s a casual, self-contained format. There are no sanctioned cube tournaments, no official ban lists, and no Wizards-enforced card authenticity rules. The only rule is the one you set: what’s in your cube. This is the same Rule Zero spirit that lets Commander playgroups run proxies — but in cube, the whole card pool is yours, so there’s nobody to “surprise” with a proxy. The deck you draft is born and dies at the table.
The best cube lists are absurdly expensive. The most popular powered cube lists on Cube Cobra — the ones packed with Black Lotus, Ancestral Recall, Time Walk, Mox Sapphire, and Mox Ruby — cost more than a used car in real cards. Individual staples like Timetwister ($8,000+), Mishra’s Workshop ($4,000+), and Gaea’s Cradle ($1,500+) are exactly the cards every drafter wants to play and exactly the cards no one can afford to sleeve up. Proxies are the only realistic way most playgroups ever draft these cards.
Cube culture already embraces proxies. Cube owners have proxied expensive additions for years — it’s how you test a $400 card before trading for it, and how you run a themed cube (like a “Power Only” cube) without a six-figure collection. On Cube Cobra, the platform most cube owners use, proxying a list is a normal, openly discussed part of the hobby. You’re not breaking a community norm — you’re joining one.
What a Real Cube Costs (And What a Proxy Cube Saves You)
Let’s put real numbers on it. Cube prices vary wildly by power level and card pool, but here’s a fair 2026 snapshot of what a 360-card cube costs in real cards:
The gap between a powered cube and a peasant cube is the entire story of why proxies matter: the cards people most want to draft — Black Lotus, the Moxen, dual lands, Tabernacle — are precisely the cards that inflate a list to five figures.
The Proxied Price, By the Numbers
MakeProxyCard uses tiered Full Color pricing, so the more cards you order, the less you pay per card:
A 360-card powered cube — the exact list that costs $10,000-30,000 in real cards — is $216 proxied. That’s a 98-99% saving, and it includes every Reserved List card you can fit in the list. The 180-card starter cube comes in at $126, which is why the title of this article promises “under $150”: the entry point to the best draft experience in Magic costs less than a single booster box, and far less than one real Mox.
The Math on a Single Staple
Consider the most expensive card you can legally play in cube: Timetwister, the $8,000+ Reserved List sorcery. One real copy costs more than 35 full proxy cubes. A single proxy of Timetwister at the 360-card tier costs 60 cents. That single comparison explains the entire economics of the proxy cube — you’re not choosing between real and fake cards; you’re choosing between a $216 draft night and a $30,000 draft night that almost nobody can actually afford.
How to Build a Proxy Cube in 5 Steps
Building a proxy cube is a weekend project. Here’s the exact workflow.
Step 1: Pick a cube archetype. The four classic starting points are: Powered (Power Nine + the strongest cards ever printed — the full fantasy), Legacy (no Power, but dual lands and top-tier staples — a very common sweet spot), Unpowered (modern staples, lower budget cards), and Peasant/Pauper (commons and uncommons only — cheapest real-card analog and a great low-cost draft). If you’re not sure, start with an Unpowered cube: it’s the most balanced draft experience and the most forgiving list to tune.
Step 2: Grab a proven list from Cube Cobra. This is the step that saves you weeks of tuning. Cube Cobra hosts thousands of curated lists — search by archetype, size, and power level, then copy a list that’s been drafted hundreds of times. Community lists have already solved the color balance, the mana curve, and the archetype support. Don’t reinvent the cube; clone a good one.
Step 3: Export the list and order your cards. Convert the list into your order — MakeProxyCard’s Build Your Deck flow takes a card list directly, and every card in the list is available in the catalog at tier pricing. For a 180-card starter, you’re looking at $126; for 360 cards, $216. Add 5-10 flex cards if you want swap options later — at 60 cents a card, it costs almost nothing.
Step 4: Sleeve and label. Double-sleeve every cube card (see the section below on sleeves). Most cube owners also print a small “cube list” sheet with the archetypes and a few draft tips — it’s the difference between a confusing pile of cards and a welcoming draft night for friends who’ve never drafted before.
Step 5: Run your first draft. For 180 cards, draft with 2-4 players (packs of 15, standard draft rules — or try Winston draft for two players). For 360 cards, you get a full 8-player pod with three packs of 15 per player. Add basic lands — most players bring their own, or keep a box of 50 of each color with the cube.
Card Quality, Sleeves, and Cube Etiquette
A cube gets handled harder than any constructed deck. Cards get picked up, passed around, piled into packs, and shuffled between every single game. That’s why quality and sleeves matter more here than in any other proxy use case.
Order 350gsm blue-core cardstock. This is the same grade MakeProxyCard recommends for competitive proxy decks: it shuffles, snaps, and feels like genuine Magic cards, and it survives the constant handling of draft nights. The 330gsm standard grade works for a casual-only cube, but if you want your draft to feel premium — and you’ll be passing these cards around a table of friends — 350gsm blue-core is worth the upgrade.
Double-sleeve everything. Cube cards get touched far more than deck cards: draft picks, deck construction, sideboarding, and resleeving between games. Double-sleeving (inner sleeve + outer sleeve) protects the card faces and backs from the wear of constant handling. Matte outer sleeves reduce glare under shop or kitchen lights and keep cards from sliding when you’re passing packs.
Use a uniform card back. In a draft, every card in the pool should look identical from the back — otherwise, experienced players can read card types from sleeve damage or back patterns. A uniform proxy back across the whole cube keeps drafts fair. This is also why you should never mix proxy cards and real cards in the same cube: the backs will differ.
Set the table rules upfront. Cube is the most proxy-friendly format in Magic, but good hosts state their house rules anyway: what power level the cube is, whether it’s singleton (it usually is — cube is almost always a singleton format), and how basics are handled. A 30-second intro makes everyone comfortable, especially first-time drafters.
The Bottom Line: Draft the Cube You Actually Want
The proxy cube is the purest expression of what proxies are for: playing the cards you want to play, at a price that makes sense. A $216 powered cube lets you and seven friends draft Black Lotus, Time Walk, and the Moxen on a Friday night — the same experience that costs five figures in real cards, and one that almost no playgroup in the world actually owns. You’re not settling for a lesser version of cube; you’re building the cube that the card market priced you out of.
Start small — 180 cards, $126, one game night — and grow from there. Every 60-cent staple you add later is a no-brainer. That’s the whole strategy: pick a proven list, order at tier pricing, sleeve it properly, and draft.
At MakeProxyCard, every card is printed at up to 1200 DPI on 350gsm blue-core cardstock with accurate MTG dimensions (63x88mm) — the same standard competitive players expect. Whether you’re building a 180-card starter for two-player Winston drafts or a full 540-card powered cube, the principle is identical: draft the cube you actually want, not the cube you can afford.
