The short version
MTG proxies are unofficial cards used to represent Magic cards during play. They are useful for testing upgrades, trying a new Commander deck, and building casual decks without acquiring every expensive card first. Whether you can use them depends on the setting: your playgroup or organizer decides what is acceptable in casual games, while player-made proxies are not authorized cards for sanctioned tournaments.
Understanding MTG Proxies: What You Need to Know comes down to three habits: ask before playing, make every card easy to identify, and keep proxy use separate from any attempt to pass an unofficial card off as authentic. A transparent, readable proxy can be a practical game piece. A card designed or presented to deceive buyers, opponents, or collectors is a different matter.
What is an MTG proxy?
In ordinary player conversation, a proxy is a stand-in for another Magic card. It might be a plainly labeled placeholder used during deck testing, a custom-printed casual game piece, or a complete proxy deck made for a consenting playgroup. The word is broad in community use, so context matters.
Official tournament documents use “proxy card” more narrowly. Under the Magic Tournament Rules, a tournament proxy is issued by a judge in limited circumstances; it is not simply any substitute card a player brings from home. This difference explains a great deal of otherwise confusing proxy advice.
Wizards has also used “playtest card” for a non-authentic card created for personal, non-commercial testing and not intended to look authentic. Its published policy distinguishes those cards from counterfeits made to reproduce genuine Magic cards deceptively. Wizards’ policy discussion of proxies and playtest cards remains useful for understanding that distinction, although event authorization is governed by the current tournament rules.
Why Commander players use proxies
Commander turns a promising deck idea into a 100-card logistics project remarkably quickly. A list may include cards you do not own, staples already tied up in other decks, uncertain upgrades, or a mana base that costs more than the commander that inspired the whole exercise. Proxies let players solve several different problems.
- Test a commander or archetype before acquiring the full deck.
- Try an expensive upgrade and determine whether it actually improves the list.
- Maintain several casual decks without moving the same staple between sleeves every game night.
- Build around a visual theme while keeping card names and gameplay information readable.
- Experiment with a higher-powered list after discussing that power target with the pod.
- Replace awkward temporary slips of paper with a consistent, sleeved testing deck.
The strongest use case is iteration. A card can look perfect in a digital list yet be too slow, too narrow, or simply unfun in the games your group plays. Testing first lets you revise the deck before treating the list as finished.
For a complete build, audit the list rather than focusing only on expensive cards. Check the mana base, ramp, interaction, win conditions, tokens, double-faced cards, and any cards sitting in a maybeboard. Our guide to turning a 100-card list into a finished Commander deck covers that larger workflow.
Are MTG proxies allowed?
There is no single answer that covers kitchen-table Commander, an unsanctioned store league, and a sanctioned tournament. The applicable rule depends on who runs the game.
| Setting | Can you use player-made proxies? | What to do |
|---|---|---|
| Private casual Commander | Only if the participants agree | Tell the pod before the game and discuss deck power as well as proxy use. |
| Local game store free play | Store and table policies vary | Ask the store and the players rather than assuming. |
| Unsanctioned store event | The organizer decides | Check the event announcement or contact the organizer before arriving. |
| Sanctioned tournament | Player-made proxies are not authorized cards | Use cards permitted by the current Magic Tournament Rules; judge-issued proxies exist only in limited circumstances. |
Sanctioned tournaments
The Magic Tournament Rules dated February 27, 2026 state that cards used in sanctioned events must generally be regulation-sized, genuine Magic cards publicly released by Wizards of the Coast. Non-authorized cards are prohibited. Owning an authentic copy elsewhere does not turn a player-made substitute into an authorized tournament card.
A Head Judge may issue a tournament proxy in specified situations, such as when a card is accidentally damaged or excessively worn during the current tournament. The rules also include a limited provision involving foil cards for which no non-foil printing exists. Players may not create their own tournament proxies under these provisions. Consult the current official Magic Tournament Rules and the event staff when tournament eligibility matters.
This is also separate from format legality. A genuine card can still be illegal because it is banned or falls outside the event’s format, while a card being legal in Commander does not authorize a player-made version for sanctioned play. Use the official Banned & Restricted list to check format legality and the tournament rules to check card authorization.
Casual Commander and local stores
Casual Commander is based on participant expectations, not a universal proxy rule. One pod may welcome complete proxy decks, another may permit proxies only for testing, and a third may prefer official cards. Stores can likewise apply different policies to free play, unsanctioned leagues, and sanctioned events held in the same building.
Ask two separate questions before playing: “Are proxies acceptable here?” and “What kind of game are we trying to play?” Permission to use proxies is not permission to ignore power expectations. A proxied precon-level theme deck and a tutor-heavy combo deck create very different games even if both contain the same number of unofficial cards.
Wizards describes Commander Brackets as optional tools for finding games with similar expectations. They can support a pregame conversation, but they are not a proxy policy and do not replace organizer approval. If your group uses that framework, the practical goal is to build a Commander Brackets proxy deck that fits your playgroup, not merely to attach a number to the deck.
Proxy, playtest card, and counterfeit are not interchangeable
Players sometimes use “proxy” for every unofficial card, but the purpose and presentation matter.
- A playtest card is an obvious stand-in used to test gameplay. It is not presented as an authentic collectible.
- A casual proxy is an unofficial game piece used with the knowledge and agreement of the other players or organizer.
- A judge-issued proxy is a substitute created by tournament staff under the limited conditions in the tournament rules.
- A counterfeit is made or presented to be mistaken for an authentic product. Deceptive representation and resale are not ordinary casual proxy use.
You do not need to imitate authentication details to make a useful Commander proxy. In fact, an obvious unofficial treatment helps preserve the distinction. The front still needs enough gameplay information for opponents to understand the card without repeatedly borrowing your phone.
How to use proxies considerately
A good proxy deck should reduce friction, not move the cost of understanding your deck onto the other three players. Prioritize disclosure, readability, consistent handling, and an honest power conversation.
Tell the table before the game
A brief explanation is enough: say whether the entire deck or only selected cards are proxies, name any especially powerful cards or compact combos, and ask whether the group is comfortable proceeding. Do this before shuffling up rather than after the first proxied fast-mana card appears.
Keep essential information readable
Each card should have a clear name, mana cost, type line, rules text, and relevant power and toughness or loyalty information. Art can be thematic, but it should not make identification harder. Consistent frames and layouts help opponents scan a battlefield containing several permanents.
Custom treatments need extra restraint for cards with dense rules text, modal choices, or multiple faces. Keep alternate faces available, and include the day/night, monarch, initiative, token, emblem, or other helper pieces the deck regularly creates. A cohesive deck is useful only if it remains playable.
Avoid marked-card problems
Cards in the library should be indistinguishable by touch or from their backs. Use uniform opaque sleeves, replace visibly damaged sleeves, and avoid mixing game pieces with noticeably different thicknesses or dimensions. Even in casual play, nobody wants the top of the deck announcing that the next draw is definitely not a basic land.
Match the deck to the promised game
Proxies change access, not card power. Replacing a basic-heavy mana base with efficient lands, adding free interaction, or introducing multiple tutors can alter a deck substantially. Discuss those functional changes rather than treating proxy count as a power rating.
For example, a deck with 70 proxies might be a low-powered typal build, while a deck with three proxies could use them for a powerful tutor, combo piece, and premium land. What the cards do is more important than how many are unofficial.
Turning a test list into a finished proxy deck
Once a list survives testing, freeze a version before ordering or printing it. Confirm that every card belongs in the deck, remove maybeboard entries, and check spelling and quantities. A normal Commander deck contains 99 cards plus one commander and follows singleton and color-identity restrictions, apart from cards whose rules specifically allow otherwise.
Then review the physical deck as a complete object:
- Verify the commander, color identity, card count, and current format legality.
- Check that the mana base supports the deck’s actual colored requirements.
- Remove obsolete test cards and duplicate singleton entries.
- Choose legible treatments for every card, especially text-heavy and double-faced cards.
- Add the tokens, emblems, counters, and reminder pieces the list needs.
- Decide how opponents will distinguish transformed, copied, manifested, or face-down cards.
- Use consistent opaque sleeves and keep a current decklist available.
- Confirm proxy acceptance and the intended power level before game night.
If you want a professionally produced deck rather than a home-printing project, a print-on-demand option such as ProxyMTG can turn a finalized list into physical game pieces. The important word is finalized: printing a list does not fix an accidental 101st card, an omitted basic land, or a token package that exists only as optimistic memory.

Common questions about MTG proxies
Do I need to own the original card?
For casual play, that is a policy choice for the group or organizer. Some groups require ownership, while others do not. In sanctioned events, owning an original card elsewhere does not authorize you to put a player-made substitute in the tournament deck.
Can I use proxies at my local game store?
Possibly, but ask first. A store may allow proxies during casual free play and prohibit them in a sanctioned event. It may also run an unsanctioned league with its own restrictions. Check the policy for the specific event, not just the building.
Should I disclose a full proxy deck?
Yes. Tell the pod before the game. Disclosure prevents avoidable disagreements and creates an opening to discuss tutors, fast mana, combos, mass land destruction, or other choices that may matter more to the game than the cards’ origin.
How many cards are in a Commander deck?
A normal Commander deck contains exactly 100 cards: 99 cards in the main deck plus the commander. It is generally singleton and must follow the commander’s color identity. Check the current official Commander page and card-specific rules when an unusual commander or deckbuilding permission is involved.
The practical takeaway
Proxies work best as transparent tools for testing and mutually agreed casual play. Ask the organizer or pod, make the cards easy to read, sleeve the deck consistently, and describe its power honestly. For sanctioned tournaments, follow the current Magic Tournament Rules rather than relying on local custom or the fact that you own another copy.
If you are starting with a digital Commander list, test the uncertain cards first. Then lock the list, audit all 100 cards and helper pieces, and build the physical deck around clarity. That approach produces something better than a pile of placeholders: a coherent deck your group can understand and enjoy playing against.
