ScrySpireCommander damage and the 21-damage rule
Take 21 combat damage from any single commander and you lose — no matter how much life you have left.
Commander damage is the format’s answer to a specific problem: in a game that starts at 40 life, a big creature that swings for eight would otherwise take five turns to matter. The rule gives commanders a second, parallel way to kill you.
The rule
A player who has been dealt 21 or more combat damage over the course of the game by the same commander loses the game. It is checked as a state-based action, so it happens the moment the threshold is reached — you do not get to untap and fix it.
- It is cumulative across the whole game, not per turn or per combat.
- It is tracked separately for each commander. Two different commanders dealing you 15 each do not combine into 30.
- It only counts COMBAT damage. A commander that deals damage with an ability or a triggered effect reduces your life total, but that damage is not commander damage.
- Commander damage is dealt in addition to reducing your life total. It is not instead of it — the same swing does both.
Partners and commanders that change zones
If you have two commanders, each one accumulates its own separate total. Eleven from one partner and eleven from the other is 22 damage but only 11 commander damage from each, and nobody dies to the rule.
Damage already dealt sticks. If a commander dies and returns — from the command zone or anywhere else — the damage it dealt earlier still counts toward that same commander’s total. Being killed does not reset the clock.
Tracking it without dice everywhere
Most tables track commander damage with spare dice next to each player, which works until a die gets bumped or a player forgets to add one. Because the totals are per attacker and per victim, they grow quadratically with the table size — the reason it is the single most commonly mis-tracked number in the format.
ScrySpire keeps the full matrix: swipe a player’s tile toward the commander that hit them and the total is recorded against that specific commander, with the threshold shown as you go. Partner commanders get their own separate tracks, and the whole thing is saved with the game so you can see afterwards who was actually beating on whom.
Frequently asked questions
How much commander damage kills you in Commander?
Twenty-one. A player who has been dealt 21 or more combat damage by the same commander during the game loses immediately, regardless of their remaining life total.
Does commander damage from two different commanders add up?
No. Each commander has its own separate total. Fifteen damage from one and fifteen from another is 30 life lost, but only 15 commander damage from each — neither reaches 21, so the rule does not trigger.
Does non-combat damage from my commander count?
No. Only combat damage counts toward the 21. If your commander pings someone with an activated or triggered ability, that reduces their life total but does not add to commander damage.
Does commander damage reset if the commander dies?
No. Damage already dealt by that commander stays on the record for the rest of the game, even if it changes zones and comes back.
Does commander damage also reduce my life total?
Yes. A commander connecting for seven takes you down seven life and adds seven to that commander’s damage total against you. The two are tracked in parallel, not instead of each other.
