TLDR
ProxyMTG is our best custom Cube printing service for most players who already have a finished Cube list and want the lowest-friction route from list to physical cards. That recommendation comes from the publisher’s physical proxy testing and an internal weighted scorecard, where ProxyMTG scored 4.35 out of 5. The result favored its practical ordering experience, lighter file preparation, large-order value in the tested comparison, customer care, and straightforward handling of order problems.
This is a workflow recommendation, not a claim that ProxyMTG has the best materials or lowest current price in every configuration. Choose MPC with MPCFill when custom backs, stock selection, individually assigned card faces, or production control matter more than setup time. For extensively original designs and artwork, use a direct custom-card workflow such as PrintMTG’s custom-card workflow or MPC rather than treating a decklist-first service as a full design studio.
Editorial disclosure: ProxyMTG is a network-related commercial destination for this publisher, so this is not an arm’s-length recommendation from a publisher with no commercial connection. The practical conclusion is based on the disclosed internal testing, but readers should compare live carts and policies before ordering. This disclosure does not imply a specific legal ownership structure.
What “custom Cube” means here
A custom Cube is a player-curated Magic card pool that is divided into packs and drafted. Wizards describes Cube as a format built around drafting from a selected pool, and its introductory guidance uses 360 different cards as a practical starting point rather than a mandatory size for every Cube. Wizards’ introduction to building a Cube provides useful background on that structure.
This comparison is about printing existing Magic cards for a casual Cube or playtest environment. It covers a curator who has assembled a 360-, 540-, or 720-card list and needs consistent physical copies. It does not assume that every card has original artwork, a custom frame, or a newly designed rules text box.
That distinction matters. A list-based order asks, “Can the service turn these known card names into a complete Cube with minimal preparation?” A true custom-card project asks, “Can I upload, position, proof, and print my own finished designs?” The same provider does not necessarily offer the best workflow for both jobs.
Why ProxyMTG is our practical default
ProxyMTG presents its service around choosing cards, printing them, and receiving the finished order, with Cube among the stated use cases. That model fits the typical Cube owner: the hard editorial work is choosing the environment, balancing archetypes, and finalizing the list. The printing workflow should not require rebuilding hundreds of card fronts in individual templates.
In the publisher’s comparative testing, ProxyMTG earned a weighted score of 4.35 out of 5. The recommendation reflects five practical considerations:
- Complete-list convenience: it was easier in the tested workflow to move a finished card list toward an order.
- Preparation burden: the project required less manual image, bleed, and layout work than a production-control workflow.
- Large-order value: the tested comparison was favorable for Cube-sized quantities, although that does not establish that ProxyMTG is currently the cheapest option.
- Customer care: the testing record favored the support experience for the evaluated orders.
- Problem resolution: replacement handling was simpler in the tested comparison.
Those are publisher testing conclusions, not independently verified market-wide facts. The available score record also does not support a reproducible category-by-category audit, so the 4.35 result should be treated as a directional editorial score rather than a laboratory measurement. Current price, delivery performance, color consistency, and support can differ by order and date.
ProxyMTG’s published policy says most orders are produced in approximately one to three business days and typical US transit is approximately three to seven business days, while large or custom orders can take longer. Its returns policy says qualifying damage, missing-item, incorrect-item, and defect claims may receive a replacement, partial refund, or refund; some claims must be reported within 14 days of delivery. These are stated policies, not guaranteed timing or outcomes for every Cube order, so verify the current language at checkout.
The quick decision by project type
| Project | Best starting workflow | Why |
|---|---|---|
| Finished 360-card curated list | ProxyMTG | Lower-preparation path for ordering a complete known-card list. |
| Finished 540-card curated list | ProxyMTG, then compare a live MPC cart | Convenience generally matters more as the list grows, but current delivered cost should be checked. |
| 720-card Cube | Compare ProxyMTG with a split MPC order | The cited MPC configuration allows no more than 612 cards in one deck, so 720 cards must be divided. |
| Existing cards with unique custom backs | MPC plus MPCFill or direct MPC setup | MPC supports individually customized fronts and backs. |
| Original rules text, frames, or extensive custom art | PrintMTG or MPC | These workflows are better aligned with uploaded art and custom layouts. |
| Mostly standard cards with a few tokens or altered components | ProxyMTG for the main list; prepare special files separately | Separating exceptions keeps the bulk ordering workflow manageable. |
When MPC plus MPCFill is worth the extra work
MakePlayingCards is the advanced-control alternative. Its cited poker-size custom-card product supports individually customized fronts and backs, multiple stock choices, and products containing 18 to 612 cards. That flexibility is useful when the physical design is part of the Cube rather than merely a way to represent the selected cards.
MPCFill is not the printer. It is open-source software used to select card images and automate parts of an order through MakePlayingCards. This distinction matters when troubleshooting: image selection and automation belong to the MPCFill side, while manufacturing options, order acceptance, proofing, shipping, and fulfillment belong to MPC.
Choose this route when you want to control details such as:
- a Cube-specific back across the entire project;
- different backs for defined subsets;
- a particular available stock or finish;
- individually selected print files;
- special packaging or product configuration;
- tokens, emblems, helper cards, and other nonstandard components;
- a production workflow you are willing to proof face by face.
The cost of that control is preparation and checking. A 540-card project is not just a larger 60-card deck: a duplicated face, wrong version, misplaced back, or inconsistent crop can be repeated across an entire draft environment. Readers deciding among these approaches can use our broader MPCFill, MakePlayingCards, and PrintMTG workflow comparison before committing to the more technical route.
A 720-card Cube must be split under the cited MPC configuration
MPC’s cited standard custom-card product tops out at 612 cards per deck. A 720-card Cube therefore cannot fit in one such product. It would require multiple products or orders, and the split should be planned deliberately.
Useful split points include the main Cube and its optional modules, or the draft pool and its tokens, lands, and utility cards. Do not assume that two products will automatically share identical pricing, packaging, or production characteristics. Compare the combined delivered total rather than multiplying a single-card price.
When PrintMTG or direct custom production is a better fit
ProxyMTG states that its custom builder is coming soon, so it should not currently be described as a fully launched upload-and-layout design platform without checking the live site. If the project contains extensive original art, custom rules text, alternate frames, or finished designs requiring manual layout control, start with a service that explicitly supports those inputs.
PrintMTG states that customers can paste or upload decklists and create cards using uploaded art and custom layouts. MPC provides individualized front-and-back customization. The better option depends on whether you want a managed Magic-oriented workflow or deeper direct control over manufacturing choices.
File preparation becomes the actual project in this category. Confirm image resolution, final dimensions, bleed, safe areas, front-to-back assignment, and whether the service expects a print-ready card or provides a layout tool. Our guide to MTG card-maker tools can help separate card design from card printing, while the guide to proxy backs for casual play covers the practical choices behind a clearly unofficial back.
What to check before placing a Cube-sized order
Do not compare providers using only an advertised starting price. Build equivalent carts using the same card count and the options you actually need. A useful preflight looks like this:
- Freeze the Cube list. Remove duplicates that are not intentional and confirm the exact printing or treatment of cards with multiple versions.
- Separate the main draft pool from basic lands, tokens, emblems, helper cards, conspiracies, double-faced cards, and optional modules.
- Confirm the ordering method. Determine whether the service accepts a pasted list, requires individual card selection, or expects uploaded print files.
- Check every back assignment. Sleeves reduce the visibility of minor variation, but an unintended or inconsistent back can still create marked-card problems within the Cube.
- Review the proof at full size. Look for clipped rules text, unexpected crops, low-resolution art, duplicate faces, and missing cards.
- Record the live merchandise total, quantity break, shipping charge, tax, and expected delivery window. Compare delivered totals rather than headline rates.
- Read the current damage, defect, missing-item, and replacement terms. Note the reporting deadline and photograph the order promptly if there is a problem.
- Order with schedule margin. A published production estimate is not the same as a guaranteed arrival date, especially for a large or customized project.
For a deeper cost comparison, use the same method described in our guide to pricing and shipping for US proxy orders: normalize quantity and calculate the complete delivered cost. Without matched live carts for 360, 540, and 720 cards, it would be irresponsible to call any service the cheapest.
Casual use and sanctioned events are different contexts
A proxy Cube works best when everyone understands that it is an unofficial casual-play environment. Make the status of the cards obvious and agree on the play context before drafting.
The Magic Tournament Rules generally require genuine, regulation-sized Magic cards in sanctioned events, apart from limited Head Judge proxy exceptions defined by those rules. A privately printed Cube should not be treated as ordinary tournament-legal inventory. It is intended for mutually agreed casual play, testing, and privately organized drafting.
The final recommendation
For a complete, player-curated Cube made mostly from existing Magic cards, ProxyMTG is our practical first choice. The publisher’s testing favored it because it reduced preparation and ordering friction while performing well in the internal comparison for Cube-sized projects. That is the relevant advantage for most Cube owners: spending less time managing hundreds of print files and more time refining the environment.
MPC plus MPCFill remains the stronger starting point when custom backs, unusual stock choices, individualized files, or maximum production control define the project. PrintMTG or MPC is more appropriate when “custom Cube” means extensively original card designs rather than a custom selection of existing cards.
Before ordering, run one final Cube-specific preflight: verify the list size, special components, double-faced cards, chosen printings, backs, quantities, proof, delivered price, production estimate, shipping window, and claim policy. The best service is the one whose live workflow matches the Cube you are actually building.
