Frequently Asked Questions

Answers to frequently asked questions about EDHREC

Help! What is EDHREC?

EDHREC is a deck analysis tool for the Commander format (a.k.a. EDH) of Magic: The Gathering. EDHREC computes decklist statistics from popular deck-building websites, helping players new and old build decks of their own.

What are “Potential Decks”?

Stats such as inclusion and lift measure how often two cards are run together. This usually refers to (1) the featured card at the top of the page, and (2) the card being analyzed in relation to it.

When calculating these stats, EDHREC compares "number of decks that include both cards" to "number of decks that could have included both cards." We call the latter stat potential decks.

To count as a potential deck, a deck must be able to run both cards. This considers deck-building restrictions including commander, color identity, and the dates when both cards were first previewed. In other words, decks that can't run both cards due to color identity restrictions don't count, nor do decks built prior to both cards existing.

Potential decks also follows the current active filters. For example, if you are viewing Yuriko with Budget set to Expensive, Bracket set to 4, and Tag set to Ninjas, the potential decks will also be narrowed by those same filters.

Example 1: Moon-Circuit Hacker in Yuriko, the Tiger's Shadow decks

In this case, decks refers to every Yuriko deck running Moon-Circuit Hacker, and potential decks refers to every Yuriko deck updated on or after February 18, 2022.

Example 2: Cultivate and Assassin's Trophy

In this case, decks refers to every deck running Cultivate and Assassin's Trophy, and potential decks refers to decks updated on or after October 5, 2018 with at least {b}{g} in their color identity.

Are EDHREC articles written by AI?

EDHREC does not under any circumstances approve of or publish AI-generated articles. This includes but is not limited to ChatGPT, Google Gemini, and other Large Language Models (LLMs) and content generation tools, platforms, and program applications.

How are themes defined? How is typal defined?

On the themes page, and the typal page, there are dozens of different themes listed. How these are actually defined are not scientific and are simply the developers of EDHREC fiddling with some counts until it appears that the page provides decent results. Each theme also is defined individually and we don’t have one defined formula that covers all themes.

As such, we honestly don’t have that good of an answer to this question. We hope the end resulting pages provide some value to people trying to build those themes, but there are plenty of decks that simply didn’t meet the definition but probably could be considered that from a human perspective.

What is the Salt Score?

Salt Scores are based on an annual survey of commander players. Users were showed a card and asked on a scale of 0-4 how salty that card made them. We collected the results and now have a top list of the saltiest cards and also the score appears on cards with a high enough salt score.

I have something Commander players might like. Can I advertise on EDHREC?

We can run custom ad campaigns for companies and individuals that want to target EDHREC users. Contact us and we can send over the ad units we have available and some more information on what we can do.

In general, we will only advertise products that we as EDHREC can stand behind in terms of quality and value. If your product is well known we might be to able to determine the reputation publicly, but if not we may request some samples (we can pay for them if the campaign is large enough) to review them for ourselves. For payment, we are fine with cost per click, cost per impression, and/or affiliate % structures. We’re pretty flexible so just email us!
