TLDR
Most casual Commander decks can handle 5 to 15 proxies without bothering anyone, as long as the cards fit the table’s power level and you are honest before the game starts.
If you are building a test deck, a cube-style Commander night, or a budget version of an expensive idea, you can use more. But for a normal recurring playgroup, the best answer to how many proxies should you use in a Commander deck is: enough to make the deck fun and playable, not so many that your deck becomes a disguised cEDH science project.
That is the line. It is not printed in the rules text, sadly. That would be too convenient.
The Real Question Is Not Just “How Many Proxies?”
The question how many proxies should you use in a Commander deck sounds like a numbers question.
It is not really.
The better question is:
How many proxies can you use before the deck stops matching the game everyone else thought they were sitting down to play?
Commander is a casual multiplayer format built around expectations. The deck has 100 cards, including the commander. You usually play one copy of each card other than basic lands. You build within your commander’s color identity. Those are the easy parts.
The hard part is the social layer.
A deck with three proxies can be miserable if those proxies are Mana Crypt, Gaea’s Cradle, and The One Ring in a low-power pod. A deck with thirty proxies can be totally fine if it is a janky Sliver Queen nostalgia build, a precon upgrade test, or a budget player trying to keep up with a group that already owns the expensive staples.
The number matters. But the reason matters more.
A Good Default: 5 to 15 Proxies
For most casual Commander players, 5 to 15 proxies is the safest default range.
That range lets you solve real problems without changing the whole identity of the deck.
You can proxy:
- Expensive lands so the deck actually casts its spells
- A few hard-to-find cards you already own in another deck
- One or two cards you are testing before buying
- Reserved List or old-border cards that are wildly overpriced
- A favorite alternate art version for flavor
- Cards that make the deck functional, not oppressive
Five proxies usually feels invisible. Ten proxies feels normal if the deck is clear and readable. Fifteen proxies starts to feel like a meaningful chunk of the deck, but still not weird if the table knows what is going on.
Once you get above that, people may start asking questions. Not angry questions, necessarily. More like, “So what exactly are we playing against here?” Which is fair. Commander players are not always calm creatures, but they are entitled to know whether your “casual brew” is secretly a luxury sports car wearing a hoodie.
Use Fewer Proxies for Unknown Tables
If you are playing at a local game store, convention, public Commander night, or with people you do not know well, keep the proxy count lower unless the group clearly allows them.
A good public-table range is 0 to 5 proxies.
That does not mean more is morally wrong. It just means public games run on fast trust. Nobody wants to spend ten minutes negotiating your deck before deciding whether to keep a seven-card hand.
At an unknown table, proxies are easier to accept when they are:
- Clearly readable
- Not pretending to be real cards
- Sleeve-friendly and not marked
- Used for casual play only
- Mentioned before the game
- Similar in power to the rest of the deck
The most important part is the pregame sentence.
Try something simple:
“I have five proxies in this deck. They are mostly lands and a couple cards I am testing. Nothing cEDH.”
That one sentence prevents a lot of drama. Commander drama is already plentiful. No need to manufacture artisanal drama from scratch.
Use More Proxies When You Are Playtesting
Playtesting is different.
If you are testing a new Commander deck before buying cards, you can proxy the whole thing. Honestly, that is one of the cleanest uses for proxies.
A 100-card Commander deck can get expensive fast, especially if the mana base includes fetch lands, shock lands, triomes, utility lands, tutors, fast mana, or old staples that have been climbing in price since dinosaurs still used dial-up internet.
For testing, proxy as many cards as you need.
That might mean:
- 100 proxies for a full concept test
- 60 proxies for a deck you are still shaping
- 20 proxies for expensive cards you are unsure about
- 10 proxies for a final round of changes before buying singles
The key is to call it what it is.
A test deck is not the same as your finished Commander deck. If your group is cool with testing, great. Run the paper version, find the clunky cards, and save yourself from buying a stack of singles that spend the rest of their lives in a sad little “maybe later” pile.
Use Proxies to Fix Mana First
If you are not sure which cards to proxy first, start with the mana base.
That sounds boring because it is boring. It is also correct.
Commander decks often lose games because they fail to function, not because they lack one more splashy mythic. A deck that cannot cast spells is not “budget.” It is furniture.
Good proxy targets include:
- Fetch lands
- Shock lands
- Battlebond lands
- Triomes
- Pain lands
- Utility lands
- Ancient Tomb
- Cavern of Souls
- Command Beacon
- Urborg, Tomb of Yawgmoth
- Yavimaya, Cradle of Growth
You do not need all of those. Please do not read that list and decide your squirrel deck needs a mortgage-grade mana base.
The point is simple: mana proxies often make games better because they reduce non-games. If your deck needs three colors and you spend the first four turns staring at the wrong lands, nobody is impressed by your financial restraint. They are just waiting for you to join the game.
Be Careful Proxying Raw Power
Some proxies help a deck function.
Others change the social contract instantly.
Be more careful with cards like:
- Mana Crypt
- Jeweled Lotus
- Dockside Extortionist-style burst mana
- Demonic Tutor
- Vampiric Tutor
- Rhystic Study
- Mystic Remora
- The One Ring
- Fierce Guardianship
- Force of Will
- Gaea’s Cradle
- Lion’s Eye Diamond
- Original dual lands
The issue is not that these cards are bad to proxy. The issue is that they send a message.
When someone sits down across from a proxy Mana Crypt, they do not think, “Ah, wonderful, this person believes in affordability.”
They think, “What turn are we dying?”
That may be unfair in some cases. But Commander is built on vibes as much as rules, and those cards have very loud vibes.
If your pod plays high-power Commander, proxy them. If your pod plays precon-plus battlecruiser games, maybe do not slide in a stack of fast mana and pretend nothing happened. That is how trust gets exiled.
Match the Proxy Count to the Deck’s Purpose
A useful way to decide how many proxies to use is to sort the deck by purpose.
Finished Casual Deck: 5 to 15 Proxies
This is the normal everyday range.
Use proxies for expensive staples, duplicate cards you own elsewhere, or upgrades you are testing. Keep the deck readable and honest.
Budget Upgrade Deck: 10 to 25 Proxies
This works well when you are trying to bring a lower-budget deck up to your group’s level.
Proxying lands, removal, and a few engine pieces can make the deck smoother without turning it into a monster.
Full Test Deck: 50 to 100 Proxies
This is fine for playtesting.
Just be clear that it is a test list. The goal is to learn whether the deck is fun, consistent, and worth building.
Cube or Battle Box Commander: As Many As Needed
Cube environments are their own thing.
If the whole experience is built with proxies, nobody is confused. In fact, proxies can make cube much cleaner because every card can match the intended environment instead of being limited by what people happen to own.
High-Power or cEDH Testing: Often 25 to 100 Proxies
Competitive Commander testing has a different culture in many groups.
When the point is to test tight lists, proxies are often accepted because nobody wants match results determined by who owns the most expensive cardboard. Still, confirm the rules of the group first.
The Best Proxy Rule: Tell People Before the Game
The best rule is not a specific number.
The best rule is disclosure.
Before the game starts, say:
- How many proxies you are using
- What kind of cards they are
- Whether the deck is casual, high-power, or cEDH
- Whether any proxies are major power outliers
- Whether the deck is finished or being tested
You do not need to read a notarized deck affidavit. Just be normal.
A good version sounds like:
“This is a mid-power Muldrotha deck. I have around twelve proxies, mostly lands and a few cards I am testing. No fast mana outside Sol Ring.”
That is enough.
A bad version sounds like:
“It is casual.”
Then on turn two you reveal a proxy Underground Sea, Mana Crypt, Rhystic Study, and a tutor chain.
That is not casual. That is a trust fall where you moved the floor.
Proxy Quality Matters More Than People Admit
A proxy does not need to be fancy, but it does need to be playable.
Good Commander proxies should be:
- Easy to read across the table
- Clear about what card they represent
- The same size as the rest of the deck when sleeved
- Not marked or thicker in a way that affects shuffling
- Durable enough for repeated play
- Not presented as authentic originals
This is where professionally printed proxy cards can make a difference for casual decks, collections, cubes, and playtesting. A clean, readable proxy is less distracting. It does not slow down the table. It does not force people to squint at a printer-paper rectangle that looks like it survived a backpack incident in 2007.
Nerdventure’s MTG proxy cards are intended for casual play, cube building, playtesting, collection use, display, and custom projects. That fits the healthy proxy lane: make the hobby easier to enjoy, do not misrepresent anything, and keep the expectations clear.
Do Proxies Make Your Deck Too Strong?
They can.
This is the sneaky part.
People often talk about proxies as a money issue, but proxies are also a deck-building issue. If cost disappears, restraint becomes the real skill.
Without a budget limit, it is very easy to add:
- Better lands
- Better tutors
- Better free interaction
- Better fast mana
- Better win conditions
- Better card draw
- Better protection
Then suddenly your “same deck, just cheaper” is not the same deck. It is sharper, faster, and less forgiving. That might be fine. But it should be intentional.
A good rule:
Proxy the version of the deck your table actually wants to play against.
Not the most optimized version you can imagine.
Not the online list with every expensive staple.
Not the deck that wins once and then mysteriously struggles to find opponents next week.
The Best Cards to Proxy First
If you are building a normal casual Commander deck, proxy in this order:
1. Mana Fixing
Start with lands that help the deck function.
A smoother mana base makes games better without necessarily making the deck oppressive.
2. Cards You Already Own Elsewhere
If you own one copy of a card and use it in three decks, proxying duplicate copies is very reasonable in many groups.
Nobody wants to move the same Cyclonic Rift between sleeves like it is the family silver.
3. Cards You Are Testing
This is one of the best uses for proxies.
Try before you buy. Cut the card if it does not perform. Your wallet will survive, and your binder will contain fewer regrettable “I swear this was good in theory” purchases.
4. Expensive Theme Cards
Some cards are expensive because collectors want them, not because they are format-breaking.
These are great proxy candidates if they make your deck feel more complete.
5. High-Power Staples
Save these for last, and only add them if they match the table.
Fast mana, tutors, and free counterspells are not automatically wrong. They are just loud. Treat them like loud cards.
So, How Many Proxies Should You Use in a Commander Deck?
Here is the clean answer.
Use 5 to 15 proxies for a normal casual Commander deck.
Use 0 to 5 proxies when playing with strangers unless the table clearly allows more.
Use 20 or more proxies when playtesting, building a cube environment, or playing in a group that openly supports proxy-heavy decks.
Use 50 to 100 proxies when testing a full deck before spending money.
And no matter the number, talk about it before the game.
That is the part people skip, and it is usually the part that causes problems.
Final Verdict
The best answer to how many proxies should you use in a Commander deck is not “as many as possible” or “none ever.”
The best answer is: use enough proxies to make the deck playable, affordable, and fun, while keeping the game honest for everyone else at the table.
For most casual decks, that means 5 to 15. For testing, use as many as you need. For public games, keep it conservative. For regular groups, set a shared expectation and stop treating every proxy conversation like a courtroom drama.
Commander is better when more people can play the decks they are excited about.
Just tell the table what you brought.
