TL;DR: MTG proxies are best for playtesting and casual games where they’re allowed. Ask the organizer/store first, be transparent with your table, keep proxies readable, and never represent or resell them as authentic Magic cards.
MTG proxies are a normal part of how many people play today—testing decks before spending big money, protecting expensive staples, or keeping a cube playable without risking real cards. The key is using proxies in a way that’s transparent, respectful, and aligned with the rules of wherever you’re playing.
This guide explains how to use proxies responsibly, avoid awkward situations at the table, and keep proxy-friendly play healthy for everyone.
What is an MTG proxy?
A proxy is a stand-in for an official Magic: The Gathering card. Proxies range from handwritten slips in sleeves to professionally printed playtest cards. The purpose is typically one of these:
- Playtesting a list before buying real cards
- Protecting expensive cards (keeping originals at home)
- Budget accessibility for casual playgroups or cubes
- Convenience (clear text/art, easy deck swaps)
The #1 rule: match the event rules
Before anything else, ask: Where am I playing?
- Wizards-sanctioned events: proxies are not allowed (with very limited exceptions like judge-issued proxies under specific circumstances).
- Unsanctioned events / casual nights: it’s up to the organizer or store.
- Home games: it’s up to the playgroup.
If you aren’t sure, the simplest move is: ask the organizer/store before you show up. If they say no, the answer is no.

Proxy etiquette: how not to be “that player”
Responsible proxy use is mostly social, not technical. These habits keep games smooth:
1) Be transparent before the game starts
Say something simple and normal:
- “I’m running a few proxies for testing—everyone cool with that?”
Don’t wait until someone notices mid-game.
2) Keep the power level conversation separate
Proxies don’t “cause” power imbalances—deck choices do. But proxies can accelerate upgrades, which means you should still do the standard pre-game check:
- What power level are we aiming for?
- Are fast mana / tutors / infinite combos on the table?
3) Make proxies readable
If a proxy is hard to identify, it slows the game down and frustrates people. Responsible proxies should be:
- Readable in sleeves
- Consistent (same general look/size)
- Easy to recognize without argument
4) Respect stores and prize support
Even if a shop is proxy-friendly for casual Commander, prize-supported nights often have different rules. Be extra cautious when:
- the event has entry fees + prizes
- the store advertises official rules enforcement
- there are judges or tournament reporting
When in doubt, ask first.
Responsible use scenarios (what’s usually fine)
These are common “green light” situations:
Playtesting before buying
You want to test whether a card actually works in your deck before you spend $50–$500. Proxies are great for this—just be transparent.
Protecting expensive cards
Some players own the real card and proxy it to avoid wear. Many playgroups are fine with this (some even prefer it). Again: communicate.
Cube and board-game style Magic
Cubes are one of the most proxy-friendly environments because the goal is gameplay, not collection flex. Proxies can help keep cubes balanced and accessible.
The hard line: never misrepresent proxies as real
This shouldn’t be controversial, but it needs to be explicit:
- Don’t sell or trade proxies as authentic
- Don’t try to “pass” proxies as real
- Don’t list proxies online in a way that could confuse buyers
Healthy proxy culture depends on honesty.

A quick script for asking a store/organizer
If you want something you can copy/paste:
Hi! I’m planning to come in for Commander night. Are proxies allowed for casual play? If yes, is there a limit (e.g., number of proxies, no proxies for prizes, etc.)?
It’s polite, fast, and it keeps the store in control of their rules.
Where to learn more (and stay consistent)

- shipping timelines and tracking
