Commander Damage Rules in MTG: What Counts and What Doesn't

Commander damage rules come down to one line: if the same commander deals you 21 or more combat damage over the course of a game, you lose. Your life total doesn't matter. You could be sitting on double your starting life and still be out of the game.

The confusing part is that commander damage isn't a different kind of damage. It's ordinary combat damage. It comes off your life total like any other hit, and on top of that the table keeps a running tab per commander. Everything below is about what goes on that tab and what doesn't.

The rule in the Comprehensive Rules

Rule 903.10a reads: "A player who's been dealt 21 or more combat damage by the same commander over the course of the game loses the game." It's a state-based action, which means nobody has to cast anything or announce it. The moment the tab reaches 21, that player is out.

Players start Commander at 40 life, so 21 is a little over half. That's why the rule matters: a commander that keeps connecting can kill someone who's been gaining life all game, and the other way around, a player at 15 life can still die to ordinary damage long before any commander gets to 21.

Commander damage vs regular damage

Every point of commander damage is also regular damage. If a 6-power commander hits you, you lose 6 life and the tab for that commander goes up by 6. Two separate counters, one hit.

What only goes on the life total:

• Damage from any creature that isn't a commander, including tokens your commander makes.
• Noncombat damage from your commander itself: a fight, a "deals damage to any target" ability, a spell that has it deal damage. The rule says combat damage, and only combat damage.
• Life loss that isn't damage at all.

That second line trips a lot of tables up. "I'm guessing it's because no one ever says 'commander combat damage'," wrote u/Phailen in an r/EDH thread on exactly this mix-up. Pinging commanders and fight effects feel like commander damage. They aren't.

What never comes off the tab: life you gain. mtg.wiki puts it plainly: "gaining life won't affect this total in any way." Lifelink on your own creatures heals your life total and leaves the commander damage you've taken exactly where it was.

What counts toward 21

Each commander keeps its own tab

The 21 has to come from the same commander. Twelve from one opponent's commander and twelve from another's is a lot of damage off your life total but zero commander-damage losses. With three opponents, you track three tabs, or more if anyone has partners.

Partners are tracked separately

Two partner commanders don't share a tab. The rules say to "consider damage from each of your two commanders separately". If Kraum, Ludevic's Opus hits you for 12 and Tymna the Weaver hits you for 10, you're still in the game. For a partner deck that plans to win by attacking, that split is a real cost. Our partner commanders guide covers which pairs are legal.

A stolen commander keeps its history

The tab belongs to the card, not to whoever controls it. Wizards' own Commander page says it outright: "if one player takes control of another player's commander, any damage that commander already dealt is still counted." So if your opponent's Uril has already hit you twice and you take it with Gilded Drake, nothing resets. And if you then attack its owner with it, that damage goes on their tab for their own commander.

It happens at real tables. "Was playing Syr Gwyn and had someone steal it from me fully equipped and kill me with her. It was funny," wrote u/AdmiralSkippy on r/mtgrules.

The same logic covers zone changes. The rules call the commander designation "an attribute of the card itself" that it keeps "even when it changes zones", so a commander that dies, goes back to the command zone and gets recast is still the same commander for the count. A token copy of it, though, isn't the card, so it isn't a commander and its damage only hits your life total. That last point is our reading of rule 903.3, not a separate ruling.

Merged and mutated commanders count

If a commander is part of a merged permanent, for example with mutate, the whole merged permanent "is that player's commander". All the combat damage it deals goes on the tab.

How many hits it takes

Hits to 21 by power, no pumps, no blockers. Image: BaseMTG chart, arithmetic on rule 903.10a.

The chart is simple division, and it's the quickest way to read a Voltron threat. A 3-power commander needs seven clean hits, which almost never happens. A 7-power one needs three. Double strike halves the count, because each hit is two combat damage steps and both go on the tab.

Rafiq of the Many is the textbook case. Attacking alone, exalted makes it a 4/4 and its own ability gives it double strike, so each swing is 8 commander damage and the third swing kills. Uril, the Miststalker starts as a 5/5 and gets +2/+2 per Aura. With two Auras it's a 9/9 and kills in three hits too, and since it has hexproof you can't target it to stop that.

The edge cases that start arguments

• Infect commanders. Infect damage to a player turns into poison counters instead of life loss, and ten poison counters loses the game. It's still combat damage, so in our reading it also goes on the commander tab, but poison gets there first. Skithiryx, the Blight Dragon hits for 4: three hits is ten poison, while 21 commander damage would take six.
• Vehicle commanders. Since the Edge of Eternities rules update, a legendary Vehicle or Spacecraft with a power/toughness box can be your commander. It only deals combat damage while it's crewed and attacking. Parhelion II is a 5/5 flier with first strike, so it needs five connected hits. The two 4/4 Angels it makes when it attacks aren't commanders, so their damage only comes off life totals.
• Brawl. No commander damage at all. The rules say Brawl games don't use it.
• Damage that gets prevented never happened, so there's nothing to count. A Fog against a Voltron commander saves you from the tab too.

How to keep track at the table

Commander damage rules only work if somebody keeps count, so pick one way and stick to it for the whole game. The usual options are a life-counter app with a commander damage grid, a dice per opponent's commander, or a line on paper per commander. Say the number out loud when it changes ("that's twelve from Rafiq") so nobody finds out two turns late that they were already dead.

If your table wants to drop or change the rule, that's a Rule Zero conversation, and it's worth having before the game starts. New to the format? Our Commander guide, how the commander tax works and how to build your first Commander deck cover the rest.

What players think of the rule

Tolarian Community College asked "Should We Get Rid Of Commander Damage?" in July 2026, and the top comments said no, for practical reasons. "yesterday I played a game where this kid managed to get over 100 life I think commander damage is pretty useful," wrote @Odyssey- in one of the most-liked comments. Another viewer, @kiwi_commander, made the deckbuilding case: "Removing commander damage directly nerfs Voltron commanders. And they already have a tough time winning games."

One reply was about how the rule changes play even when nobody dies to it. "In my play group, the amount of ppl who actually die to commander damage is fairly rare but it does make everyone play in a way where they see being hit by an Emmett commander as more serious," wrote @ataraxia7439. That matches the chart: the threat is real for big commanders and almost theoretical for small ones.
