TLDR: For Rule 0 proxies Commander conversations, say how many cards are proxied, whether any are custom designs, and what the deck actually does. Mention fast mana, tutors, free interaction, compact combos, or another major power signal. Then ask whether the table and venue are comfortable with it. Casual consent cannot override a store policy or sanctioned-event rules.
A good proxy conversation does not need to become a committee hearing. It needs to give the other players enough information to choose the game they are about to play. “I have eight proxies” is less useful than “I am testing eight cards, including two fast-mana pieces, and the deck can threaten a win around turn six.” Quantity matters, but the resulting play experience matters more.
The 30-second Rule 0 proxy script
Use this basic script and replace the brackets with honest answers:
“Quick proxy check: this deck has [number or proportion] playtest cards, including [important examples]. They represent existing Magic cards, not custom designs. The deck is trying to [strategy], usually becomes threatening around [turn or game stage], and it runs [fast mana, tutors, free interaction, compact combos, or none of those]. Is everyone comfortable with that here?”
If you are at a store or organized event, add one sentence before shuffling: “Is this casual play, and does the organizer allow player-made proxies?” That question separates three issues people often mash together: the pod’s preference, the venue’s policy, and sanctioned-event legality.
Three layers decide whether proxies are appropriate
| Layer | Question to ask | Who decides |
|---|---|---|
| Commander pod | Does everyone want to play this game with these proxies and this power profile? | The players at the table |
| Store or organizer | Does this venue or event permit player-made proxies? | The host, store, or organizer |
| Sanctioned event | Do the current Magic Tournament Rules permit these game pieces? | Official policy administered by event staff |
Commander is presented by Wizards as a casual multiplayer format, and its Commander Brackets are offered as an optional tool for pregame discussion. Wizards also says bracket philosophy and intent matter alongside card counts, and the framework is identified as beta. The official Commander format page is the place to check its current form.
That social framework does not grant permission to ignore a host’s rules. A private pod can accept a handwritten test card while a particular store event refuses it. Another organizer might welcome proxies in an unsanctioned Commander night but prohibit custom cards. There is no universal casual proxy limit in the supplied official guidance, so ask instead of quoting a number somebody’s old playgroup invented.
Disclose the game experience, not just the proxy count
A proxy is a substitute game piece. It does not independently determine power. A proxied basic land is still a basic land; a proxied piece of zero-cost acceleration still does what that card does. The useful Rule 0 conversation therefore covers both the physical substitutes and the deck they enable.
- Quantity: Give a number, a rough proportion, or say clearly that the entire deck is proxied.
- Purpose: Explain whether you are testing possible purchases, maintaining multiple decks, playing cEDH, or using long-term casual stand-ins.
- Power and pace: Say when the deck generally expects to become threatening rather than relying only on a vague one-to-ten rating.
- Acceleration: Mention unusually efficient fast mana when it can put the deck materially ahead of the table.
- Tutors: Disclose whether they mostly find utility pieces or repeatedly assemble the same win.
- Interaction: Mention dense free interaction or protection if it changes how opponents must play.
- Win conditions: Identify compact combos, deterministic loops, mass land denial, or similarly consequential plans.
- Card identity: Say whether every proxy represents an existing Magic card or whether the deck includes custom rules text.
Commander Brackets can provide shared vocabulary, but they are not a substitute for the useful details. The supplied official framework describes lower brackets as more socially focused and higher brackets as increasingly powerful or competitive. Because the system is beta and can change, check the current official page rather than memorizing an old Game Changers list.
Expensive staples and high power are different questions
Price can be the reason you proxy a card, but price is not a reliable power rating. An expensive land may make a mana base more consistent without creating a fast combo deck. A cheap tutor or combo piece may have a much larger effect on pace. Discuss what the card changes, not what an authentic copy costs.
For a mana-base test, try: “I’m proxy-testing five lands before deciding whether they belong in the deck. They improve color consistency, but I have not added fast mana or changed the win condition.” A controlled test is more informative when you record the cards replaced and avoid changing fifteen unrelated slots at once. The Commander mana-base proxy-testing workflow explains how to structure that experiment.
For expensive staples, try: “I have six expensive cards represented by playtest cards. Two are stronger acceleration, one is a tutor, and the others are lands. The deck can assemble a two-card combo, but it is not built for cEDH speed.” That tells the table far more than announcing the combined market price like an auctioneer.
Scripts for common proxy situations
A few test cards
“I’m testing four possible upgrades tonight. They are clearly marked playtest cards representing existing cards. One is a tutor, but the deck is still aiming for a longer casual game. Is that fine with everyone?”
A fully proxied deck
“This entire deck is proxied. Every card represents a real Magic card, the faces are readable, and there are no custom designs. It is a high-power list with fast mana, several tutors, free interaction, and a compact combo. I have another deck if that is not the game we want.”
Full-deck proxies deserve clearer disclosure because the other players cannot reasonably infer your choices from a handful of visible substitutes. State that the deck is fully proxied before play, summarize its strategy and strongest power indicators, and bring an alternative when playing with unfamiliar people. If you are preparing a long-term test deck, consistent and legible MTG proxy cards can also reduce the confusion caused by a pile of mismatched paper slips.
A cEDH or other competitive list
“This is a fully proxied cEDH deck. It is built to win efficiently and interact on the stack, not to play a relaxed upgraded-precon game. Is this a cEDH table?”
Do not bring that deck to an explicitly casual pod and treat proxy permission as permission for any power level. The mismatch is competitive intent versus social intent, not cardboard ownership.
A custom commander or custom card
“My commander is a custom design with rules text that does not exist on an official card. Here is the complete text. Are you interested in trying a game against it? No problem if not—I brought a normal deck too.”
Custom cards require a separate yes. A reskin or alternate-art representation with unchanged official text is still representing an existing card. A card with new abilities, costs, stats, or characteristics changes the game’s rules environment. The Tournament Rules identify Oracle as a card’s official text, which provides a useful dividing line between alternate presentation and new game design.
Keep the physical cards fair and readable
Table consent does not fix unreadable cards or marked-card problems. Players should be able to identify a card, understand its relevant text, and distinguish it from other objects without asking for a translation every turn. Sleeves should conceal differences in card backs, edges, thickness, and paper inserts.
- Use one consistent sleeve type across the deck.
- Make names, mana costs, types, and rules text readable.
- Do not use artwork or frames that make cards deliberately easy to confuse.
- Check that paper inserts do not produce obvious bulges or tactile differences.
- Handle double-faced cards without revealing hidden information.
- Keep current Oracle text available when an alternate treatment is unclear.
Before game night, run the proxy deck marked-card checklist. Double-faced cards also need a consistent system; these five ways to handle proxy DFCs focus on readability and hidden-information fairness.
Proxy, playtest card, and counterfeit are not synonyms
For a clean conversation, distinguish the objects involved:
- Authentic card: an official Magic card.
- Proxy or playtest card: an unofficial stand-in used transparently.
- Counterfeit: a fake represented, or intended to be represented, as authentic.
- Custom card: a new design with game text or characteristics not belonging to an existing Magic card.
In a 2016 policy statement, Wizards distinguished visibly non-authentic personal, non-commercial playtest cards from counterfeits intended to pass as authentic. That statement is useful for terminology, but it is not the current rulebook for sanctioned events. Wizards’ proxy-policy statement
Transparency is the practical line. A playtest card should not need to fool anybody to perform its job. Label questionable pieces, avoid authentic-looking presentation intended to deceive, and never represent an unofficial card as genuine when trading or selling.
How to decline without turning Rule 0 into combat
Players can decline proxies, custom cards, or a particular power mismatch. They do not need to prove that their preference is the one true philosophy of Commander. A useful response is brief and specific:
“I’m fine with test cards, but I’m not looking for a game against custom designs tonight.”
Or: “That list sounds faster than the decks we brought. Do you have something slower, or should we find you a high-power table?”
If someone declines your proxy deck, do not litigate their collection, income, or moral character between mulligans. Switch decks, adjust the list, or find another pod. Rule 0 is a consent process, not a mechanism for forcing consensus.
Rule 0 does not override sanctioned-event rules
The Tournament Rules document supplied for this article is labeled effective February 27, 2026. It requires sanctioned events to use regulation-sized, genuine Magic cards publicly released by Wizards and prohibits unauthorized cards. It also says players may not create their own tournament proxies. A Head Judge can issue a proxy only in narrow circumstances described by the rules, including specified card-damage situations and certain foil-only cases.
Before bringing player-made proxies to organized play, ask two direct questions: “Is this event sanctioned?” and “What is the organizer’s proxy policy?” Do not rely on what happened at last month’s casual Commander night. Venue permission for an unsanctioned game and eligibility for a sanctioned event are separate matters.
Quick answers to common questions
Are proxies allowed in Commander?
In informal Commander, their use depends on the pod and host. There is no universal casual numeric limit established by the supplied sources. Ask before play and describe the deck honestly.
Can a store ban proxies?
A store or organizer can set rules for its space and events. A pod’s agreement does not override the host’s policy.
Is a fully proxied deck okay?
It can be when the pod and host agree. Disclose it clearly, ensure every card is readable and physically fair, explain the deck’s power indicators, and be ready to use another deck.
Do expensive cards automatically make a deck high power?
No. Price and power can overlap, but they are not equivalent. Explain whether the cards increase speed, consistency, tutoring, resilience, interaction, or access to compact wins.
Are custom cards different from proxies?
Yes. A proxy represents an existing card; a custom card introduces a new design. Ask for separate consent, even if the custom card appears balanced.
Can player-made proxies be used in sanctioned events?
The supplied Tournament Rules say players may not create their own tournament proxies. Only a Head Judge may issue one under the narrow circumstances specified in the rules. Check the current document and speak with event staff before playing.
The rule to remember
A solid Rule 0 conversation answers three things: what is unofficial, what the deck does, and who has authority over the game. Disclose the proxies, describe the meaningful power signals, and check the venue. If the answer is no, switch decks or tables without making it weird. Thirty honest seconds now can prevent a two-hour argument later.
