Is Commander Damage Only Combat Damage? Learn MTG rules, examples, and tips to understand how Commander damage actually works.
If you’ve ever played the Commander format of Magic: The Gathering, you’ve probably had a game where someone gets knocked out, not by a massive life drop, but by something called Commander damage … a fascinating part of Culture & Trends within the MTG community.
I still remember experiencing it for the first time.
It was a casual Friday night with friends, we were all gathered around the table, there were snacks everywhere, the decks were shuffled and ready. My Atraxa, the voice of the Praetors played, shone like a powerhouse. A friend of mine looked dead at me after a big blow and said:
“This is Damage 21 Commander. You’re out.”
What are you waiting for? I had 35 lives left!
That moment drove me crazy… Searching forums, reading official rules, watching YouTube explanations. I needed to know: Is commander damage only combat damage? Or can abilities and spells also matter?
If you’ve found yourself asking the same thing, you’re not alone. Let’s clear this up… Once and for all.
Short answer: Yes, Commander damage is just combat damage.
To get straight to the point:
Commander damage is calculated only from the combat damage your commander does in battle.
- Disadvantages:
- Activated or triggered abilities
- Spells cast by your boss
Effects or triggers of loss of life
…21-Does not count towards the damage limit.
So if your boss catches someone with a spell-like effect, it’s normal damage… Not boss damage. Only those hits in the attack phase count towards the end of the game 21.
What is Commander damage anyway?
Let’s go back for a moment.
In Commander (also known as EDH… Elder Dragon Highlander), each player starts with 40 life and chooses a legendary creature as their commander. This card represents the leader of your deck and can be regenerated from the command zone if it dies.
Now here’s the kicker:
If a boss deals 21 or more battle damage to the same player during the game, that player loses, regardless of his or her life total.
It doesn’t matter that they’re sitting on 100 lives from life-gain effects… 21 battle damage from the same boss is letting them down.
21 Why the loss? The origin of the rule
It’s not just a random number.
“21” comes from the early roots of Commander… When the format was literally called Elder Dragon Highlander (EDH).
The original Elder Dragons, such as Nicol Bolas, Vevictis Asmadi, and Arcades Sabbath, were all 7/7 creatures.
Three clean hits (7×3) = 21.
So the number stuck. This was a fun nod to the game’s origins… Which indicated that a true “Commander” could defeat an opponent in three decisive attacks.
How Commander Damage works… Step by step
Let’s break it down simply:
- A boss deals combat damage
During the battle phase, your boss attacks and damages a player.
Example: Edgar Markov swings for 6. This is 6 commander damage.
- The damage increases throughout the game
The vessel’s damage is not reset. Even if your boss leaves the battlefield, goes into exile, or changes control… It still counts.
- When a player takes 21 or more from a boss
That player loses immediately, regardless of the sum of his remaining lives.
That’s it. No extra moves, no special counters, no ability damage. Just pure fighting power.
What Doesn’t Count as Commander Damage
Here’s where most confusion happens … because not all damage feels the same in MTG.
Let’s clear this up with examples:
| Type of Damage | Example | Counts as Commander Damage? |
| Combat damage from attacking | Commander attacks and hits for 7 | Yes |
| Activated ability (e.g., “Tap: deal 3 damage”) | Niv-Mizzet’s ability | No |
| Spell damage (like Lightning Bolt) | Commander casts spell that deals 3 | No |
| Noncombat triggers | “When this deals damage to any target…” | No |
| Life loss effects | “Target player loses 2 life” | No |
| Prevented damage (e.g., Fog) | Damage prevented | No |
Even if the damage source is your commander, it must be combat damage … meaning it happened in the attack phase, either unblocked or through trample, double strike, etc.
Examples of real games: When it comes to
Let’s say you’re playing Kalia of the Vast and you kill an opponent multiple times in a row.
- Turn 5:6 damage
- Turn 6:8 damage
- Turn 7:7 damage
That opponent now has a total of 21 Commander battle damage from Kalia… And they lose the game immediately, even though they have 40 lives left.
But what if Kalia used an ability or spell outside of combat to deal damage? None of this will count.
Advanced Commander damage rules (which many players forget)
Even experienced players sometimes abuse these nuances. Let’s dig deeper.
1. Commander damage never resets
When a boss deals damage to a player in battle, the damage is permanently tracked for the rest of the game.
- It does not matter if:
- The boss is destroyed, banished, or sent back to the command zone.
The same manager is later reappointed.
Kul continues where it left off.
2. Separate count for each boss
If multiple commanders are present (as partner commanders), their damage is not combined.
Example:
You have Tymna the Weaver and Thrasios the Triton hero.
Timna received 15 damage, Thrasios received 10 damage.
This is not a total of 25… Because each boss’s damage is tracked separately.
A player only loses when a boss automatically reaches 21.
3. You can lose to your own boss
Yes, it’s true… If your boss is stolen and used against you, you can be defeated by your own blade.
Imagine your opponent takes control of Xenagos, God of Revels and uses it to deal 21 damage to you.
Even if it’s your commander, it’s still the card that deals combat damage… And the rules apply. You are out
4. Damage prevented or modified does not matter
If an effect like fog, creature protection, or damage prevention wears off, that combat damage is never “dealt.”
That means it is not added to the Commander damage table.
5. Copies are not commands
If a card like Clone makes a copy of a boss, that copy is not considered the “real” boss.
Although it looks similar and deals damage in battle, it does not trigger the Commander damage rules.
6. Commander status matters
If a creature becomes a Commander during play (for example, through a special rule or variant), only the damage it takes after becoming a Commander counts.
Damage before this is not retroactively counted as pilot-in-command damage.
My personal opinion: Why this rule makes the boss special
Honestly, I think this rule adds beautiful tension to the format.
Commander isn’t just about big spells or endless combos. It’s also about personality… Your story tells. Commander damage adds this fun “boss fight” energy. Every attack feels personal.
When I first understood the 21-damage rule, it completely changed the way I built decks.
I started paying more attention to combat-focused commanders… Who could close out fights through pressure, not just combos.
Cards such as:
- Rafik, among many (Double Strike deals damage quickly!)
- Skithyrix, Blight Dragon (Infected and Flying… Awesome combo)
- Najeela, Blade-Blossom (extra battle stages means faster 21 hits)
When you start thinking in combat math, you start to see Commander in a whole new light.
Strategic implications of loss of commander
Knowing that only combat damage matters changes how you approach games… And how you assess threats.
1. Aggro decks provide most of the benefits
Decks that rely on combat-focused strategies naturally benefit from the Commander damage rule.
If you can get your boss to connect quickly… Especially with double hits, stomps, or unblockable effects… You can close out the game faster.
2. Life benefits don’t save you
You might be sitting at age 80 and feel invincible… But if Edgar Markov stays connected, you’re one game away from losing.
3. Voltron shines
“Voltron” is all about equipping your boss with gear, aura or buffs… Turning it into a one-shot machine.
Because Commander stacks with damage, Voltron decks are uniquely powerful.
Even if you can’t drain all 40 lives, you only need to reach 21 total battle damage.
4. The control deck must control the match
If you’re playing a control or combo deck, this rule reminds you:
You cannot ignore war forever. Sooner or later, a big, flying commander can break through your defenses… And it’s game over.
Example Scenario Recap
Here’s a recap table for quick reference:
| Scenario | Counts as Commander Damage? | Explanation |
| Commander attacks and hits player | Yes | Combat damage counts |
| Commander’s ability deals 3 damage | No | Ability damage |
| Commander casts Lightning Bolt | No | Spell damage |
| Damage prevented by Fog | No | Not dealt |
| Opponent steals your commander and attacks you | Yes | Still your commander |
| Partner commanders each deal 10+ | No | Separate tallies |
| Copy of commander deals damage | No | Copy not commander |
Common misconceptions
Let’s tackle some quick myths that still confuse experienced players:
“All the damage to your commander counts.”
No. Only battle damage matters… Not abilities, magic, or life loss.
“Commander’s damage resets when he dies.”
Also fake. The total is maintained throughout the game.
“Partner commanders share total damage.”
They don’t. Each boss’ damage is tracked individually.
“Life gain can save you from Commander damage.”
Error again. Even with infinite lives, 21 battle damage from a single boss means you lose.
Why does Commander damage make the format better?
Commander damage isn’t just a weird rule… It’s a balancing tool.
Without it, decks with life gain can dominate endlessly, and combat-focused strategies will suffer.
But with this rule, even a single creature can become a valid win condition.
It keeps the game connected to its roots: combat, strategy and personality.
And honestly? Looking across a table and realizing someone’s boss just turned 21 is one of the most dramatic, fun, and satisfying moments in all of MTG.
Key takings
