Commander Brainstorm: Kira Nerys, Firebrand

Quick answer

Commander Spotlight

Kira Nerys, Firebrand ↗

Three mana (one generic, one red, one white) for a legendary 4/3 Bajoran Soldier with trample. If a creature you control would enter while you control an attacking creature, instead it enters tapped and attacking. Whenever another creature you control enters, it gets +1/+1 until end of turn. Rare, Star Trek (TRK), releasing November 13, 2026.

Kira Nerys, Firebrand is a three-mana Boros commander, and her best trick is timing. A creature that enters attacking after your opponents have declared blockers is unblocked, so every flash creature, instant-speed token spell and "put a creature onto the battlefield" effect in your deck becomes damage your opponents cannot block. The three builds below use that in different ways: flash creatures at Bracket 2, instant-speed tokens with burn payoffs at Bracket 3, and big creatures cheated in mid-combat at Bracket 3 or higher.

Why Kira is worth a brainstorm

Most Boros commanders reward you for attacking. Kira rewards you for what you do after you attack, which is a different deck. Four rules decide how she plays, and each one changes which cards are good with her.

After blockers, new attackers are unblocked. A creature put onto the battlefield attacking during the declare blockers step or later enters unblocked (Comprehensive Rules 506.3d). Your opponents block what they can see, and then you add attackers they cannot answer in combat.

You choose who each new attacker hits. In Commander every opponent is a defending player during your combat, so a creature that enters attacking can go at any of them, not only the player Kira attacked (Comprehensive Rules 508.4 and 802.2). That lets you send damage at the player with the lowest life total after you have seen everyone's blocks.

Attack triggers do not fire. A creature that enters attacking never "attacked," so abilities that say "whenever this creature attacks," exert and battle cry do nothing for it (Comprehensive Rules 508.3a). Enters abilities still trigger, which is why this page leans on cards with strong enters abilities.

She needs an attacker, and it cannot be her own re-entry. The effect only applies while you control an attacking creature, and it does not apply to Kira herself as she enters (Comprehensive Rules 614.12). Blinking Kira takes her out of combat. Casting her from the command zone mid-combat puts her in untapped. The effect is also mandatory: a mana creature you flash in during combat enters tapped and cannot tap for mana that turn.

Three builds at a glance

Build 1: The Ambush (Bracket 2)

This is the build that plays most like Kira's card. You attack with Kira and whatever else is safe to send, let your opponents block, and then cast flash creatures that come in attacking and unblocked. A table learns quickly that an open mana pool on your turn means more attackers than they can see, and that makes every block a guess.

The fun is in the blink pieces. Say an opponent blocks your second attacker. You flash in Restoration Angel , which enters attacking and unblocked, and use its enters ability to blink the blocked creature. That creature comes back attacking and unblocked, and its own enters ability triggers again. A block your opponent made on purpose now does nothing.

Flash creatures

Restoration Angel ↗

Four mana at instant speed. Flash it in after blocks and it attacks unblocked as a 4/5 flier, then blinks one of your blocked attackers so that creature comes back attacking and unblocked too.

Saavik, Stoic Student ↗

From the Star Trek set. Flash, and when she enters she deals X damage to an attacking or blocking creature, where X counts the creature types among your creatures (at least four with Kira out). Kill the creature blocking Kira and all of Kira's damage tramples through to the player.

Archangel Avacyn ↗

Flash in after blocks: a 5/5 flier attacking unblocked, and every creature you control is indestructible for the rest of the turn, so the blocks your opponents made cost them and not you.

Captain Jean-Luc Picard ↗

From the Star Trek set. Your other creatures get +1/+1, and each creature spell you cast makes a 1/1 Officer. Cast a creature mid-combat and both bodies enter attacking.

Resolute Reinforcements ↗

Two mana, flash, and it brings a 1/1 Soldier with it. With Kira out that is two unblocked attackers with +1/+1 each for two mana.

Bogardan Hellkite ↗

The top of the curve. Five damage divided as you choose clears the blockers off your attackers, and the 6/6 flier it becomes this turn is unblocked.

Village Bell-Ringer ↗

Three mana, flash. After blocks it enters attacking and unblocked, and its enters ability untaps every creature you control, so your attackers are back up to block on the next turn.

Flash enablers and blink

Winding Canyons ↗

A land that gives every creature spell flash for the turn. Activate it before combat and your whole hand is ambush material.

Vedalken Orrery ↗

The same effect as a permanent artifact: everything you cast has flash, all game.

Cloudshift ↗

One mana. Blink a blocked attacker and it returns attacking and unblocked, with its enters ability again.

Ephemerate ↗

Cloudshift that rebounds: blink an attacker after blocks now, and blink a creature again for free in your next upkeep.

Emergence Zone ↗

The budget Winding Canyons: pay one and sacrifice it for a turn of flash on every spell, not only creatures.

Win condition. There is no single finisher. The deck wins by dealing more damage each combat than the board suggests: Kira's 4 trample, plus 8 to 12 power of unblocked fliers she brings with her. Kira's commander damage is a slower second route, and a reliable one, because Saavik, Stoic Student and Bogardan Hellkite remove her blockers and trample sends the rest through.

Why Bracket 2. The deck needs no Game Changers, no tutors and no combos, and its threats are creatures any table can answer with ordinary removal. What it has is surprise, which is exactly the kind of power a Core table enjoys playing against. On opponents' turns, the same flash creatures enter untapped and can block, so holding mana up is never wasted.

Build 2: The Resistance Cell (Bracket 3)

Kira spent the occupation of Bajor as a resistance fighter, and this build plays like a resistance cell: the attackers your opponents see are never all of them. Instead of flash creatures, it runs instant-speed token spells and creatures that make tokens when you cast spells. Every token gets Kira's +1/+1, so a 1/1 token is a 2/2 the turn it arrives.

Token makers

Secure the Wastes ↗

X 1/1 Warriors at instant speed. Cast it after blocks and every one of them is an unblocked 2/2.

White Sun's Zenith ↗

X 2/2 Cats at instant speed, and it shuffles itself back into your library to be found again.

Raise the Alarm ↗

The cheap version: two mana for two unblocked 2/2s.

Young Pyromancer ↗

Every instant you cast during combat makes a 1/1 Elemental, which enters attacking. Your combat tricks become extra attackers.

Monastery Mentor ↗

The same idea for any noncreature spell, and the Monk tokens have prowess, so the next spell you cast pumps them again.

Felidar Retreat ↗

Crack Evolving Wilds or a fetch land after blocks and the landfall Cat Beast enters attacking. A land in play becomes a hidden attacker.

Turning tokens into damage

Warleader's Call ↗

Boros's own Impact Tremors with an anthem attached. Each creature entering pings every opponent, and each token is a 3/3 with Kira's bonus.

Impact Tremors ↗

One damage to each opponent per creature, for two mana. With an X token spell, the X is also the damage.

Purphoros, God of the Forge ↗

Two damage to each opponent per creature entering, and it is indestructible, so a board wipe aimed at your tokens leaves it behind.

Goblin Bombardment ↗

Reach after combat. Tokens that dealt their damage can be thrown at a player or at the blocker that killed something.

Cathars' Crusade ↗

Every creature that enters puts a +1/+1 counter on each creature you control. Five tokens from one X spell is five counters on everything, the attackers already in combat included.

Win condition. One X spell after blocks. With Warleader's Call on the battlefield, Secure the Wastes for X = 5 costs six mana, deals 5 damage to each opponent from the enters triggers, and adds five unblocked 3/3 attackers you can aim wherever you want. That is 30 damage across the table from one card, before Kira or anything else connects. Add Purphoros, God of the Forge or Impact Tremors and the same spell ends the game.

Why Bracket 3. Nothing here is a two-card combo, but a deck that can deal 30 or more damage from an instant out of nowhere wins faster than a Core table expects, and the bracket guidelines ask you to say so. It also has room for up to three Game Changers. Smothering Tithe fits best, since Treasure pays for X spells.

Build 3: Orbital Drop (Bracket 3, scaling to 4)

The third build skips the small creatures and uses Kira to make the classic "put a creature onto the battlefield" cards better than they have ever been in Commander. Sneak Attack and Through the Breach normally give your opponents a chance to block the creature they bring in. With Kira, you use them after blocks, and an 8-mana creature arrives attacking and unblocked for a fraction of its cost.

The cheat pieces

Quicksilver Amulet ↗

Pay four and tap it to put a creature from your hand onto the battlefield, at instant speed. With Kira attacking, whatever you put in enters attacking.

Sneak Attack ↗

Usually used before combat, where the creature can be blocked. With Kira you activate it after blocks, so the creature arrives unblocked. It is still sacrificed at the end step.

Through the Breach ↗

The one-shot instant version of Sneak Attack. Five mana for whatever is the biggest thing in your hand.

Warstorm Surge ↗

Each creature that enters deals damage equal to its power to any target. Order Kira's +1/+1 trigger to resolve first and that damage goes up by one.

Ilharg, the Raze-Boar ↗

A cheat every turn rather than at instant speed: when Ilharg attacks, a creature from your hand goes in tapped and attacking, and it returns to your hand at the end step to do it again.

What to cheat in

Inferno Titan ↗

Its enters ability splits 3 damage, which is enough to clear a blocker or two off Kira. Its attack trigger will not fire this turn (see below), but the enters trigger does.

Terror of the Peaks ↗

Lands as the first threat, then every creature after it deals its power in damage when it enters, before it deals combat damage too.

Moonshaker Cavalry ↗

When it enters, your creatures gain flying and +X/+X, where X is how many creatures you control. Cast after blocks, it ends the game more often than not.

Akroma's Will ↗

Not a creature, but the finisher this deck wants: with Kira on the battlefield you get both modes, so the attackers have double strike and protection from every color.

Myr Battlesphere ↗

Put it in after blocks and its four Myr tokens enter attacking and unblocked too, each with Kira's +1/+1. One card is five attackers.

Threefold Thunderhulk ↗

It enters with three +1/+1 counters and makes Gnomes equal to its power. Order Kira's trigger first and that is four Gnomes, all entering attacking.

Order your triggers. When a creature enters, Kira's +1/+1 trigger and any damage trigger ( Terror of the Peaks , Warstorm Surge ) all go on the stack together. Put Kira's on top so it resolves first, because those damage triggers check the creature's power when they resolve.

Win condition. One large creature, unblocked, with an enters ability that either removes blockers from Kira or deals damage directly. Moonshaker Cavalry joining five other creatures gives all six +6/+6 and flying, and it is the cleanest single-card finish the deck has.

Why Bracket 3, scaling to 4. Cheating in 8-mana creatures on turn five is faster than a Core deck, so this starts at Upgraded. Its three Game Changers can be Gamble (to find Sneak Attack or the threat), Jeska's Will and Ancient Tomb . Add more than three and it is a Bracket 4 deck, which is a fine place for it as long as you say so at Rule 0.

Cards that look right but are not

Boros has plenty of creatures that care about attacking, and most of them do less with Kira than they appear to. A creature that enters attacking was never declared as an attacker, so these three lose the part of their text you want. Each is still playable, but only as a creature you cast before combat.

Hero of Bladehold ↗

Battle cry and the Soldier tokens both say "whenever this creature attacks." A creature that enters attacking never attacked, so neither ability fires. Hero is still a fine card in the deck, but only as a creature you declare as an attacker.

Glorybringer ↗

Exert happens as a creature is declared as an attacker. Put Glorybringer in mid-combat and it is a 5/5 flier with no exert. Cast it before combat instead.

Combat Celebrant ↗

The same problem: exerting it is the cost of the extra combat, and you cannot exert a creature that entered attacking.

What every build shares

Under each plan, the deck is a normal Boros Commander deck. It wants two-mana rocks like Arcane Signet , Boros Signet and Talisman of Conviction so it can hold mana open on its own turn, cheap removal like Swords to Plowshares and Chaos Warp , and a way to keep Kira alive, because she is three mana and every build loses its instant-speed tricks without an attacker on board. Boros Charm does both jobs: indestructible against a wipe, or double strike on a Kira who has already trampled past her blocker. See the Commander deck template for the baseline counts.

Weaknesses

Every build depends on having an attacker when the trick resolves, so instant-speed removal on Kira before blocks, or on your only attacker in response to a flash spell, turns your ambush into an ordinary creature that enters untapped. Attack with a second creature when you can afford to. Settle the Wreckage and similar cards that punish attacking creatures hit harder against this deck than most, since everything you add joins the attack. Fog effects stop all of it at once.

Which build should you pick?

Pick The Ambush if you like holding mana up and making opponents guess, or if your table plays at Bracket 2. Pick The Resistance Cell if you would rather win with one big turn and enjoy counting damage across the table. Pick Orbital Drop if your pod plays at Bracket 3 or 4 and you want the most explosive version of the commander. Build the list in the Deck Lab, and check its bracket with Rate My Deck before you sit down.
