What is the 75% rule in MTG?

If you have heard someone say "this is a 75% deck" and had no idea whether that meant casual, sweaty, or somewhere in the mushy middle, this article is for you.

The short answer: the 75% rule in MTG is a Commander deckbuilding philosophy. Jason Alt described a 75% deck as one that is about 75% of the way to a fully optimal build, strong enough to beat tuned decks if you play tight and get a little lucky, but not built to crush every weaker table on sight. He laid that out in his original 2014 CoolStuffInc article, "Building a 75% Commander Deck."

That matters because "75%" is not an official rule, not a line in the Comprehensive Rules, and not a secret Commander power-level formula. It is a way to build decks for multiplayer games where you want your deck to function, scale, and still leave room for other people to play Magic.

If you're a Commander player trying to figure out whether your deck is casual, tuned, or quietly becoming a problem, this is the framework people are talking about.

Key takeaways

• The 75% rule is a Commander deckbuilding philosophy, not an official MTG rule.
• The idea came from Jason Alt's 2014 writing about building decks that can compete without steamrolling casual pods.
• A 75% deck is usually interactive, coherent, and strong, but not maximally optimized.
• It is more useful than vague "power level 7" talk because it focuses on how a deck actually plays.
• Commander brackets help describe pods, while 75% still helps you decide how hard to tune your own list.

Quick answer

Here is the clean definition.

The 75% rule in Magic: The Gathering is the idea that a Commander deck should be powerful enough to compete with strong decks, but not so ruthlessly optimized that it pubstomps casual pods.

A 75% deck usually aims for three things:

• it can execute its own game plan reliably
• it can interact with stronger decks when needed
• it avoids the most repetitive or oppressive cards that make mixed-power pods miserable

If you want the blunt version, a 75% deck is trying to win fair-ish games in unfair environments.

Where the 75% idea came from

The term came from Jason Alt's Commander writing in 2014. In that original article, he described 75% decks as decks that are "75% of the way to an optimal build" and good enough to beat 100% decks if you play well and get lucky. The bigger point was not the exact number. The point was experience.

He was arguing for decks that let you do something powerful without making every game feel predetermined. That same ethos shows up again in later discussions of the theory, including the 2019 Commanderin' MTG Podcast episode with Jason Alt, which points back to both the original article and his follow-up writing on the idea.

So if you were looking for a hidden Commander rulebook entry, there isn't one. This is culture, not law.

What a 75% Commander deck actually looks like

This is where the concept gets useful.

A 75% deck is not just "medium power." It usually has a clear plan, a decent mana base, real interaction, and actual ways to close games. What it often cuts are the cards and lines that make the deck feel maximally efficient at the cost of table quality.

Common traits of a 75% deck

A 75% list often has:

• a focused commander and game plan
• enough ramp to keep up, usually around 8 to 12 pieces
• enough card draw to keep the deck moving, often 8 to 10 sources
• removal and stack interaction that can answer scary stuff
• synergy-driven win conditions instead of pure goldfish speed
• fewer tutors than a high-power list
• fewer fast-mana spikes that blow out slower tables

It is trying to be functional, not sloppy. The idea is not "play bad cards on purpose." The idea is "stop tuning every slot like you are trying to win a 4-round event."

What a 75% deck usually avoids

Most 75% decks steer away from at least some of the following:

• stacked fast mana beyond the usual baseline
• tutor density that turns every game into the same script
• compact two-card combos as the default finish
• prison pieces that stop weaker decks from participating
• all-gas mana bases and hyper-efficient curve compression

That does not mean none of those cards can ever appear. It means the deck should not be defined by them.

The easiest way to understand 75%

Think of it like this.

A precon says, "I hope my engine shows up."

A high-power list says, "I am going to make my engine show up."

A 75% deck says, "My engine will usually show up, but I am not going to strip all the randomness and social friction out of the format to force it every single game."

That is why scalable cards matter so much here. Cards like Beast Within, Swords to Plowshares, and Cultivate are still great in mixed pods because they are strong without being warped around the most degenerate lines possible.

75% rule vs power level 7

These get mashed together constantly, but they are not the same thing.

The problem with "power level 7" is that everybody uses the number differently. We already have a GrimDeck post on how badly that breaks down in real pods: The Rule 0 Conversation Is Killing Commander Games.

The 75% idea is a little more useful because it asks different questions:

• How consistently does this deck execute?
• How many tutors smooth out variance?
• How much fast mana is pushing the opening turns?
• Does this deck end games in the same way every time?
• Can weaker decks still play a game against it?

That is better than everybody saying "mine is a 7" and hoping nobody is hiding a turn-4 combo kill.

75% rule vs Commander brackets

This is the part that matters in 2026.

Wizards of the Coast introduced the Commander Brackets beta in 2025 as a shared language for pairing games, especially in stores and events. Gavin Verhey described it as something more useful than the old 1-to-10 power scale, while still leaving room for Rule 0 conversations and honest table expectations in the official announcement, "Introducing Commander Brackets Beta."

That means Commander now has two different tools floating around:

So no, the bracket system did not kill the 75% idea. It just changed where it is most useful.

Use brackets to describe the game you want. Use 75% thinking to decide how mean your deck really needs to be.

A 75% deck checklist

If you are wondering whether your own deck fits the idea, this gut-check is more helpful than pretending the answer is a perfect percentage.

Your deck is probably close to 75% if...

• it has a strong plan and can actually finish games
• it can answer a scary commander, combo piece, or engine
• it does not rely on drawing the exact same tutor package every game
• it wins more through synergy than through raw card-quality bullying
• it can steal games from stronger decks without making casual decks miserable

Your deck is probably past 75% if...

• the opening hand with fast mana changes the whole table dynamic immediately
• you routinely tutor for the same line by turns 3 to 5
• most wins come from compact combo instead of natural board development
• weaker pods have to hard-target you before your first untap step
• your deck feels "polite" only because you promise not to cast the worst stuff in it

That last one is a dead giveaway. If your deck needs a verbal disclaimer every game, the list is usually stronger than you are admitting.

Why Commander players liked the 75% rule in the first place

The philosophy caught on because it solved a real social problem.

Commander has always had a weird tension between self-expression and efficiency. People want to play their pet cards, cast splashy spells, and build around weird legends. But they also do not want to sit there durdling while somebody else plays solitaire with tutors and fast mana.

The 75% approach says you do not need to pick one extreme.

You can build a deck that:

• has real interaction
• scales into stronger pods
• still lets battlecruiser decks have a game
• wins because the deck is coherent, not because it is packed with the most brutal shortcuts possible

That is a much healthier target for a lot of kitchen-table Commander than "make it as strong as the internet says it can be."

Common mistakes people make with the 75% rule

Mistake 1: treating 75% like a precise measurement

It is not a math problem. There is no spreadsheet that tells you 74% vs 81%.

The number is shorthand. The real question is whether your deck creates competitive games across a wider band of tables.

Mistake 2: using 75% as an excuse for underbuilt decks

A 75% deck is not a pile. It still needs ramp, draw, interaction, and a plan.

If your deck folds to its own mana base, never sees its engine, and has no way to stop anything, that is not 75%. That is just loose deckbuilding.

Mistake 3: pretending a fully optimized deck is 75% because you "play it casually"

Nobody is fooled by this one.

If the list is loaded with premium tutors, dense fast mana, and the same deterministic finish every game, it is not magically a 75% deck because you say you are chill.

The list matters. The play patterns matter. The table experience matters.

So, should you build around the 75% rule now?

For a lot of players, yes.

If you mostly play with a regular pod that has already figured out its own rhythm, you may not need the phrase at all. But the underlying philosophy is still useful.

It is especially useful if:

• you bring one deck to mixed store pods
• your group has a wide range of budgets and experience levels
• you want your deck to punch up sometimes without crushing down constantly
• you are tired of the fake precision of 1-to-10 power numbers

In those spots, 75% is still one of the better deck-tuning ideas Commander has produced.

Final answer

The 75% rule in MTG is a Commander philosophy, not an official rule. It means building a deck that is strong, interactive, and coherent without tuning every slot for maximum oppression.

If the power-level scale feels useless and full cEDH optimization feels like overkill, this is the middle ground a lot of players were actually trying to describe the whole time.

And if you want to see where your own list lands before you shuffle up, building it inside GrimDeck's deck builder makes that a lot easier than guessing from memory. You can look at the list as a whole, trim the cards that push it from "scalable" into "obnoxious," and keep the deck honest.
