What Are Proxies in MTG? A Deep Dive into Substitutes, Customs, and Rules
In the complex economy of Magic: The Gathering, the value of a deck can range from a few dollars to tens of thousands. This financial barrier often leads players to ask: what are proxies in MTG?
Technically, a proxy is any card used in a game of Magic to represent a different card. While most professional players associate proxies with playtesting, the definition has expanded in 2025 to include high-quality customs for collectors and Commander enthusiasts. This guide covers the technical nuances of creation, the ethical landscape, and the strict regulations governing their use.

The Technical Definition of a Proxy
A proxy card acts as a placeholder for an actual game card. In a strict sense, it carries the same mana cost, type line, and text box as the original card but lacks the authentic copyright and manufacturing origin of Wizards of the Coast.
Why Players Use Proxies
1. Playtesting: Competitive players often print low-quality sheets of cards to test a deck's synergy before purchasing the real list. This saves hundreds of dollars in potential bad investments. 2. Preservation: Older cards (e.g., Reserved List staples like *Mox Diamond* or *The Tabernacle at Pendrell Vale*) are expensive and fragile. Players may use proxies to protect the "real" card from wear during shuffling. 3. Aesthetics: With the rise of "Altered Art" and digital tools, players create proxies with unique anime art or pixel-art renders to customize their Commander decks.

The Spectrum of Proxy Quality
Not all proxies are created equal. In the MTG community, proxies are generally categorized by their fidelity to the original printing.
1. Sharpie / Basic Land Proxies
The most accessible form. A player takes a basic land (usually a forest or island) and writes the name of the card (e.g., "Sol Ring") on it with a permanent marker.
- Cost: $0.00
- Durability: High (using a real card stock)
- Acceptance: High in casual play; low in competitive.
- Cost: ~$0.05 per page (paper + ink).
- Durability: Medium (paper can curl).
- Visibility: Clear art and text.
- Pros: They feel like real cards and shuffle well.
- Cons: The card back is often a different hue or texture than a standard MTG card, making them identifiable in a deck unless double-sleeved perfectly.
- Legal Status: Selling these is illegal (Trademark/Copyright infringement). Owning them is a grey area, but using them to deceive others is universally condemned.
- Technological Arms Race: In 2025, distinguishing high-end fakes requires UV lights and jewelers' loupes to analyze the blue glue line used in official card construction.
2. Color Printed Inserts (Slip-in Proxies)
Players create a digital image of the card, cut it out, and slide it into the front of a card sleeve alongside a basic land or junk rare. This hides the art of the back card while displaying the proxy art.
3. High-Quality Printed Proxies
Services like MakePlayingCards (MPC) or specialized Etsy sellers allow users to upload custom fronts and backs. These are printed on actual card stock with a standard poker size (63mm x 88mm).
4. Counterfeits ("Chinese Fakes")
This is the most controversial tier. These are mass-produced cards designed to bypass authenticity checks—often copying the holographic rosette patterns and specific card stock thickness of genuine Wizards of the Coast prints.

How to Make Your Own Proxies (The Ethical Way)
For educational and playtesting purposes, here is how the majority of players generate DIY proxies for kitchen-table games.
Step 1: Digital Creation
Players use software like Photoshop, GIMP, or dedicated web tools to format images.
Python Script: Mass Generating Card Frames
For users comfortable with code, Python can be used to automate the resizing of raw art images to fit card frames.
import os
from PIL import Image
def resize_image_for_mtcg(image_path, output_path): # Standard MTG card size is 63x88mm, roughly 748x1050 pixels at 300dpi target_size = (748, 1050)
try: with Image.open(image_path) as img: # Resize image to fit card frame img_resized = img.resize(target_size, Image.Resampling.LANCZOS)
# Save as high-quality JPEG img_resized.save(output_path, "JPEG", quality=95) print(f"Processed: {image_path}") except IOError as e: print(f"Error processing {image_path}: {e}")
Example usage loop
source_folder = "./raw_art" output_folder = "./prints"
for filename in os.listdir(source_folder): if filename.endswith(".png"): resize_image_for_mtcg( os.path.join(source_folder, filename), os.path.join(output_folder, filename) )
Step 2: Printing and Cutting
1. Printer: Use a laser printer for durability. Inkjet smudges if the card sweats (e.g., humid weather). 2. Paper: 67lb Bristol cardstock provides a stiffness closest to real MTG cards. 3. Cutting: Use a precision paper cutter (guillotine style) rather than scissors to ensure the corners are perfectly square, allowing them to slide into sleeves easily.

Where Can You Use Proxies?
Understanding the "Rules of Engagement" is critical to avoid being disqualified or banned.
1. Sanctioned Tournaments (WPN)
2. Commander (EDH) / Casual Play
3. Proxy-Legals (Unsanctioned)

The Ethics of Buying Proxies
A common question is: *"Where to buy proxies mtg?"*
You will find thousands of listings on sites like Etsy, eBay, and AliExpress. However, buyers must navigate the distinction between Custom Services and Counterfeits.
The "Test Print" Loophole
Many sellers avoid copyright strikes by listing items as "Test Prints" or "Custom Art Cards." They claim the item is a transformative art piece.
Ethical Guidelines for 2025:

Conclusion
Proxies in MTG serve a vital function: they democratize the game. They allow players to experiment with powerful cards, protect their investments, and express their creativity through custom art. While they remain banned in professional tournaments, their acceptance in casual Commander circles has never been higher. As technology advances, the line between "proxy" and "card" will continue to blur, making it more important than ever for players to understand the distinction between a tool for playtesting and a product for fraud.
Whether you are writing on a Forest with a Sharpie or ordering a high-resolution custom print, the goal of MTG is to have fun—provided everyone at the table agrees on the rules of engagement.
