Rules & Tracking
How to Track Commander Damage
Commander damage is combat damage dealt by a specific commander, tracked per opponent, that ends the game outright at 21, separate from life total. Here's the rule in plain language and the five things that actually keep it accurate at the table.
1. Know the rule
A player who has been dealt 21 or more combat damage by the same commander over the course of the game loses the game, regardless of their life total. This only counts combat damage dealt by that specific commander, not damage from a spell, a different creature, or a different player's commander.
2. Track it per opponent, per commander, not as one shared pool
Commander damage is tracked separately for every commander that's hit you. In a four-player pod, you need up to three separate Commander damage counters as one player, one for each opponent's commander (more if someone's playing partner commanders, since each partner is tracked individually).
3. Update it the moment combat damage resolves
Don't wait until end of turn or 'whenever someone asks.' Commander damage totals get disputed almost entirely because someone tried to reconstruct three attacks from memory after the fact. Update the counter as soon as damage is dealt, while everyone at the table can see it.
4. Call out the total out loud on big attacks
Before combat damage is applied on an attack that could be close to lethal, say the running total out loud: "That's 14 Commander damage from your Meren, putting you at 14." It costs five seconds and prevents the most common kind of table dispute.
5. Use a tracker built for it
A life tracker app that separates Commander damage from general life loss, per opponent, removes the manual math entirely. TurnZero HQ tracks Commander damage this way by default for every pod size, from 1v1 up to six players and Two-Headed Giant.
Why Paper Tracking Falls Apart
Commander damage is the single most argument-prone number at a Commander table, because it's easy to lose track of who's dealt what to whom across a dozen turns of combat. A notepad works until someone attacks with two creatures in one turn and nobody's sure which hit landed on which player.
Use one running total per opponent's commander, visible to the whole table.
Update immediately after damage. Never "I'll add it up later."
Say the new total out loud after any attack that could be close to lethal.
Use an app that separates Commander damage from life loss automatically.
Watch It Tracked in a Real Game
This is a full Commander game in TurnZero HQ, opening on the part that matters here: combat resolving, with commander damage counted per opponent alongside the life totals. The rest of the walkthrough covers setting up the gathering, choosing decks, and the end-of-game stats.
Frequently Asked Questions
How much Commander damage does it take to lose the game?
21 combat damage from a single commander, tracked across the whole game (it doesn't reset between turns). A player at 40 life can still lose outright to Commander damage if they've taken 21 from one commander, even with life total to spare.
Does Commander damage include damage from a commander's abilities, or only combat damage?
Only combat damage counts toward the 21-damage rule. If a commander deals damage through an ability or a triggered effect rather than combat, that damage still reduces the target's life total, but it does not count toward the Commander damage total that can end the game.
How do you track Commander damage with partner commanders?
Each partner commander is tracked separately, the same as if they were two different players' commanders. A player facing two partner commanders from one opponent needs two separate running totals against that opponent, not one combined number.
Can Commander damage from your own commander count against you?
No. A player only loses to Commander damage dealt by an opponent's commander. Damage your own commander deals to you (from an effect, not combat, since you generally won't attack yourself) doesn't apply toward this rule.
Track Commander damage automatically, every game.
TurnZero HQ separates Commander damage from life loss by default, for every pod size, with no mental math required.
