What’s in the Klingon Fury Commander deck?

Klingon Fury is the red, white and black deck from MTG Star Trek. Its face commander is Worf, Defiant Commander, a 5-mana 3/4, and Kor, Cause of Vengeance is the second legend you can lead with. Nearly every creature is a Klingon or a Warrior, from Martok and Kurn to Chancellor Gorkon and Voq, and three Klingon ships are in the box: the I.K.S. Negh’Var, a K’t’inga-class battle cruiser and a K’Vort-class raider.

The deck lists for $74.99 and sells for about $70.31 on TCGplayer. It releases November 13, 2026, but Wizards said on October 16 that Star Trek Commander decks in North America may arrive after that date. See our Star Trek delays guide for every region.

How does the Worf deck win?

Worf rewards you for spreading your attacks around. His Battlefront ability triggers whenever you attack: exile the top X cards of your library, where X is the number of opponents you attacked this turn, and you can play those cards until the end of your next turn. Attack all three opponents in a four-player game and Worf gives you three extra cards every turn. He also makes a 2/1 Klingon Warrior with haste when he enters.

Seven other cards in the deck have Battlefront. Rite of Ascension makes a 2/1 attacker for each opponent you attacked, Martok hands out +1/+1 counters, Kurn draws cards, Korok pumps your whole team and The Beacon of Kahless makes extra mana. Own the Day, World at War and Combat Celebrant give you extra combats, and the goad cards (Kang, Koloth, Galvanizing Tenor and Disrupt Decorum) force your opponents’ creatures to attack each other instead of you.

That’s the plan every upgrade below builds on: go wide with Klingon tokens, attack every opponent every turn, and make each attack count twice.

What are the best Klingon Fury upgrades?

These 10 picks start from what early Worf players on EDHREC add most, then get checked against the deck’s plan. Every card image links to the card on TCGplayer.

1. Windcrag Siege

What it does: As it enters, choose Mardu or Jeskai. In Mardu mode, whenever a creature attacking causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time.

Why it fits Worf: Every Battlefront ability is an attack trigger, so all of them trigger twice. Worf exiles twice as many cards, Rite of Ascension makes twice as many tokens, and Kor lets you sacrifice and draw twice. It’s the best 32 cents you can spend on this deck.

Price: about $0.32 (TCGplayer) · in 58% of EDHREC Worf decks

2. Isshin, Two Heavens as One

What it does: A 3/4 with the same effect as Windcrag Siege: whenever a creature attacking causes a triggered ability of a permanent you control to trigger, it triggers an additional time.

Why it fits Worf: Isshin and Windcrag Siege stack, so with both out every Battlefront ability triggers three times. He’s also red, white and black, so he could lead this deck himself.

Price: about $3.80 (TCGplayer) · in 33% of EDHREC Worf decks

3. L’Rell, Fierce Visionary

What it does: At the beginning of combat on your turn, create a 2/1 red Klingon Warrior with haste, then sacrifice it at the next end step. You can also pay {2} and sacrifice another creature or artifact to surveil 1.

Why it fits Worf: A free hasty attacker every turn means you always have a body to send at the last opponent. It’s the most-played new Star Trek card in early Worf decks, and with Skullclamp that token turns into two cards a turn.

Price: about $0.55 on preorder (TCGplayer) · in 54% of EDHREC Worf decks

4. Prosper, Tome-Bound

What it does: A 1/4 with deathtouch. At your end step, exile the top card of your library, and you may play it until the end of your next turn. Whenever you play a card from exile, create a Treasure.

Why it fits Worf: Worf’s extra cards are all played from exile, so every one of them also makes a Treasure. That’s ramp and card flow in one card, and the deathtouch body keeps attackers away from you.

Price: about $5.22 (TCGplayer) · in 50% of EDHREC Worf decks

5. Swords to Plowshares

What it does: Exile target creature. Its controller gains life equal to its power.

Why it fits Worf: One mana at instant speed, and it pairs with Path to Exile as the deck’s cheapest answers. Spending one mana on removal leaves the rest of your turn for creatures.

Price: about $1.09 (TCGplayer) · in 58% of EDHREC Worf decks

6. Zurgo Stormrender

What it does: Mobilize 1: whenever Zurgo attacks, create a tapped and attacking 1/1 red Warrior, sacrificed at the next end step. Whenever a creature token you control leaves the battlefield, draw a card if it was attacking. Otherwise, each opponent loses 1 life.

Why it fits Worf: This deck makes a lot of tokens. Klingon tokens that die in combat draw you cards, and the ones sacrificed at the end of the turn, from L’Rell or Zurgo himself, drain every opponent. He’s a Warrior, so Gagh Slinger makes him cheaper.

Price: about $4.47 (TCGplayer) · in 42% of EDHREC Worf decks

7. Fire Lord Zuko

What it does: Firebending X: when he attacks, add X red mana, where X is his power, until end of combat. Whenever you cast a spell from exile or a permanent you control enters from exile, put a +1/+1 counter on each creature you control.

Why it fits Worf: Every card you cast from Worf’s exile pile puts a counter on your whole team. Cast three in a turn and your 2/1 tokens become 5/4s. The Avatar: The Last Airbender crossover card fits right in with the Klingons.

Price: about $0.45 (TCGplayer) · in 38% of EDHREC Worf decks

8. Adeline, Resplendent Cathar

What it does: Vigilance. Her power equals the number of creatures you control. Whenever you attack, for each opponent, create a 1/1 white Human token that’s tapped and attacking that player.

Why it fits Worf: She adds an attacker at every opponent, every turn, so your pressure spreads across the whole table the way Worf wants. With Windcrag Siege or Isshin she triggers twice, which is six tokens a turn in a four-player game.

Price: about $2.76 (TCGplayer) · in 25% of EDHREC Worf decks

9. Skullclamp

What it does: Equipped creature gets +1/-1. Whenever the equipped creature dies, draw two cards. Equip {1}.

Why it fits Worf: Put it on a 2/1 Klingon token and the token dies right away, so 1 mana draws two cards. Worf, Rite of Ascension, Glory to the Empire!, Sins of the Father and the upgrades above all make tokens, so Skullclamp never runs out of targets.

Price: about $4.63 (TCGplayer) · in 17% of EDHREC Worf decks

10. Boros Charm

What it does: Choose one: 4 damage to target player or planeswalker, permanents you control gain indestructible until end of turn, or target creature gains double strike until end of turn.

Why it fits Worf: Nothing in the box keeps your whole board alive through a wipe, and a go-wide deck loses everything to one. Boros Charm stops “destroy” wipes for 2 mana. When you don’t need that, it’s double strike on your biggest attacker or 4 damage to finish someone off.

Price: about $4.65 (TCGplayer) · in 12% of EDHREC Worf decks

How much does it cost to upgrade the Klingon Fury deck?

All 10 cards cost about $27.94. Nothing on the list costs more than $5.25, and the two cheapest key pieces, Windcrag Siege and L’Rell, cost under $1 together. If you only buy one card, make it Windcrag Siege: it’s tied with Swords to Plowshares as the most-played nonland upgrade in early Worf decks, and it doubles the deck’s best abilities for 32 cents.

L’Rell is a Star Trek card that’s still a preorder with only a handful of listings, so its price may move before November 13.

Which 10 cards should you cut from the Klingon Fury deck?

Worf’s deck wants a wide board that attacks every opponent every turn. These cards work against that plan: they wipe your own board, hand your opponents extra cards, or sit back on defense. Where EDHREC has numbers, the percentage is how many early Worf decks still run the card.

• Vanquish the Horde: it destroys every creature, including the board you spent the game building. Ruinous Ultimatum stays as the wipe that only hits your opponents.
• Pest Control: it destroys nonland permanents with mana value 1 or less, and that’s every one of your 2/1 Klingon tokens, plus your Sol Ring.
• Ambassador K’Ehleyr (25%): her parley ability makes every player draw a card each turn, so your three opponents get three cards for every one you get.
• Alexander, Ship’s Fool: the same problem for 5 mana. Every player draws whenever he taps.
• Concerted Effort: 4 mana to share keywords like first strike and flying that the deck barely has. It doesn’t share menace or haste, the two keywords this deck actually uses.
• Right of Vengeance: it only works when creatures hit you, and the goad cards in this deck already send attacks elsewhere.
• Merciful Mandate: a defensive trick that untaps your team or ends a combat. Worf’s deck wants to be the one attacking.
• Cha’DIch Investigator (38%): 5 mana for a 4/4 and a 2/1 token. It’s the weakest of the deck’s 5-drops, and Prosper or Zurgo do more for less.
• Grilka, Widowed Warrior: 6 mana to borrow one creature for a turn. The top of the curve already has Glory to the Empire!, Own the Day and Ruinous Ultimatum.
• Mind Stone (8%): with 38 lands, Sol Ring, Arcane Signet, three Talismans and The Beacon of Kahless, it’s the weakest mana rock, and Prosper’s Treasures cover the ramp.

The trade adds up. Two board wipes go out for Swords to Plowshares and Boros Charm, the two cards that feed your opponents go out for card draw that only helps you (Prosper, Zurgo and Skullclamp), and the slow or defensive cards go out for creatures that make every attack bigger.

What we kept on purpose

• Disrupt Decorum (8%): goaded creatures have to attack someone else on their owners’ turns, so they’re usually still tapped when your turn comes around. That’s an open lane for your whole team.
• Ruinous Ultimatum (17%): it destroys every nonland permanent your opponents control and none of yours. It’s the one wipe this deck wants.
• Terminate and Night’s Whisper (8% each): early high-budget decks swap these for pricier cards, but 2-mana instant removal and two cards for 2 mana still earn their spots.
• Koloth, Tribble Hunter (46%): every player gets Tribbles that can’t block and must attack. Your opponents’ Tribbles have to attack each other, and yours are extra attackers.
• The Promise of Kahless: sacrifice one Klingon or Warrior and it returns every other Klingon and Warrior creature card from your graveyard. It’s your comeback after someone else wipes the board.
• Lightning Greaves (25%): shroud keeps Worf safe from targeted removal, and it costs nothing to move.

Which lands should you upgrade in Klingon Fury?

Klingon Fury already has Vault of Champions, a dual land that enters untapped when you have two or more opponents. Luxury Suite and Spectator Seating are the other two lands from that cycle in Worf’s colors. Luxury Suite is the most-played land added to early Worf decks, and the three shock lands are close behind.

Cut Terramorphic Expanse, Evolving Wilds and Temple of Malice first, since all three put a land onto the battlefield tapped. If you add all five, cut Canyon Slough and Umbral Expanse too. The two Commander lands cost about $13.02, and all five cost about $39.91.

Which other Klingons should you add?

Want more Klingons on the table? Four cards from the main MTG Star Trek set show up in about half of early Worf decks. They’re still preorders, so their prices may move before release.

• Gowron, Eager for Battle (about $3.32, in 50% of decks): he grows whenever another creature dies, and sacrificing a Klingon to him draws a card.
• General Chang, Cold Warrior (about $3.48, 50%): a 1-mana legend whose sacrifice ability puts a +1/+1 counter on every Klingon you control.
• The Duras Sisters (about $1.99, 50%): a 2-mana 3/2 that leaves a 2/1 Klingon token behind when they die.
• D-7 Battle Cruiser (about $1.08, 46%): a 2-mana Spacecraft that makes a hasty 2/1 Klingon for the turn every combat once it has 3 charge counters.

What are the best premium upgrades for Worf?

• Ingris Stingerquill (about $8.25, in 33% of decks): whenever a creature you control attacks, it deals 1 damage to each opponent. With a wide board, that’s a lot of damage before blocks.
• Dawn’s Truce (about $9.07, 33%): for 2 mana, you and your permanents gain hexproof, and your permanents also gain indestructible if you promise an opponent a card.
• Deadly Rollick (about $24, 38%): exile target creature, and it’s free to cast while Worf is on the battlefield.

Is the Klingon Fury deck worth buying?

Yes, if you like to attack. At about $70.31 it’s the most aggressive of the four Star Trek decks, it’s packed with Klingon legends from Kor and Kang to Martok and Voq, and the upgrade path above costs under $30. If you’d rather build a fleet, read our Federation Fleet upgrade guide or the We Are the Borg upgrade guide, or compare all four in our Star Trek Commander decks guide.

Klingon Fury FAQ

Who is the commander of Klingon Fury?

The face commander is Worf, Defiant Commander, a 5-mana red, white and black legend. Kor, Cause of Vengeance is the second legend: a 4-mana 4/4 that lets you sacrifice another creature whenever you attack to draw a card and give your Klingons and Warriors +2/+2.

What does Battlefront mean in MTG?

Battlefront abilities trigger or scale with the number of opponents you attacked this turn. Worf’s version exiles that many cards from the top of your library for you to play, so attacking every opponent gets you the most cards.

When does the Klingon Fury deck come out?

It releases on November 13, 2026 with MTG Star Trek. Wizards said on October 16 that the Commander decks may arrive later in North America.

What is the cheapest Klingon Fury upgrade?

Windcrag Siege costs about 32 cents and is in 58% of early Worf decks. Fire Lord Zuko is about 45 cents.
