Klingon Fury Attacks Twice for Three Mana. Here's How the Worf Precon Plays, and What to Upgrade
Attack all three opponents, tap The Beacon of Kahless for three red mana, and Own the Day costs exactly that: the Klingon Fury precon pays for its own second combat, and every Battlefront trigger fires again. Here's how Worf's engine plays, the rule that trips up your own tokens, five swaps for $10.24 that add no combos and no Game Changers, and the $5 Equipment that makes it a Bracket 3 deck.
You attack all three opponents. It doesn't matter with what, or whether anybody blocks: Worf, Defiant Commander exiles the top three cards of your library, and you can play them until the end of your next turn. In your second main phase, you tap The Beacon of Kahless. Its Battlefront ability adds mana of one color equal to the number of opponents you attacked this turn, so you pick red and get . Own the Day costs , minus for each opponent you attacked, which makes it right now. Cast it, and every creature that attacked untaps. After this main phase there's an additional combat phase, and when you attack again, every "whenever you attack" ability in your deck triggers again, still counting three opponents. Both cards are in Klingon Fury.
Klingon Fury is the Mardu deck () among the four Star Trek Commander precons, and it hits tables November 13 at $74.99. Twenty-three of its 24 creatures are Klingons or Warriors, eight cards carry Battlefront, a new ability word that counts the opponents you attacked this turn, and three cards give you extra combats. Out of the box it has no Game Changers and no combos. Below you'll find how Battlefront works, three tricks in the box, the rule that trips up your own tokens, five swaps for $10.24 that keep it at Bracket 2, and the $5 Equipment that doesn't.
(When we first looked at the set in July, this deck was reported as Mardu, go-wide and led by Worf. All three held. Wizards published the full list on October 28.)
The full stock list is in DeckCortex, card for card, as a deck you can open, copy and edit:
Two commanders, two speeds
Worf costs and is a 3/4. When he enters, you create a 2/1 red Klingon Warrior creature token with haste, so the turn he lands you already have something that can attack. His Battlefront ability is the deck's card draw, sort of: whenever you attack, you exile the top X cards of your library, where X is the number of opponents you attacked this turn, and you may play those cards until the end of your next turn. Lands included, and you still pay for the spells.
The second commander, Kor, Cause of Vengeance, is the sacrifice build: for a 4/4. Whenever you attack, you may sacrifice another creature. If you do, you draw a card, then Klingons and Warriors you control get +2/+2 until end of turn. Worf turns every attack into cards. Kor turns one token per attack into a card and a bigger team, and he costs one less.
Battlefront counts opponents, not damage
Battlefront is an ability word, so it has no rules meaning of its own. Every Battlefront ability in the box uses the same number: the opponents you attacked this turn. Each opponent counts once, no matter how many creatures went at them, whether they blocked, or how many combats you had. In a four-player game it tops out at three. Eight cards use it, and they're all in this deck:
| Card | Cost | Battlefront, where X is the number of opponents you attacked this turn | |---|---|---| | Worf, Defiant Commander | | whenever you attack: exile the top X cards of your library, play them until the end of your next turn | | Kurn, Son of Mogh | | whenever Kurn attacks: you draw X cards and lose X life | | Martok, Hero of the Empire | | whenever you attack: a +1/+1 counter on each of up to X target creatures you control | | Korok, Liberated Rage | | whenever Korok attacks: creatures you control get +X/+X until end of turn | | Galvanizing Tenor | | whenever it attacks: goad up to X target creatures | | Rite of Ascension | | whenever you attack: a tapped and attacking 2/1 red Klingon Warrior token with haste for each opponent you attacked this turn | | The Beacon of Kahless | | : X mana of one color (it also taps for one mana of any color) | | Own the Day | | costs less for each opponent you attacked; untap all creatures that attacked this turn, then an additional combat and main phase |
So attack everybody, every turn, even if all you have is one 2/1 for each of them. A blocked token still counts. Kurn, Korok and the Tenor have to attack themselves; the others only need you to attack with something.
The rest of the box pays you for the same habit. Glory to the Empire! makes a 2/1 hasty Klingon Warrior for each opponent you have and gives all your creatures melee, which is +1/+1 for each opponent you attacked that combat. Shared Animosity gives each attacker +1/+0 for every other attacking creature that shares a creature type with it, and Gnarling Targ gives Klingons and Warriors +2/+0 and trample whenever you attack.
Three tricks in the box
Attack, tap the Beacon, attack again
Here's the opener in numbers. In a four-player game, attack all three opponents with anything. In your second main phase, tap The Beacon of Kahless for its Battlefront mana: three mana of one color, so . Own the Day costs and gets cheaper for each opponent you attacked, so it's , and the Beacon pays all of it. It untaps all creatures that attacked this turn, and after this main phase there's an additional combat phase followed by an additional main phase.
In that combat, X is still three, because Battlefront counts the whole turn. Declare attackers again and every "whenever you attack" ability triggers again: Worf exiles three more cards, Rite of Ascension makes three more attacking 2/1s, and Martok puts out three more counters. If Kurn attacks again, you draw three more cards and lose three more life. Then you get a third main phase to play what Worf exiled.
World at War and Combat Celebrant give you extra combats too, and each one fires the same triggers. Celebrant's comes right after the current combat with no main phase in between, so you can't cast a sorcery off it.
One 0/1 gives the whole team double strike
Concerted Effort costs . At the beginning of each upkeep, creatures you control gain flying until end of turn if a creature you control has flying, and the same is true for double strike, first strike, trample, vigilance and a few more. Ferocious Colonist is a 0/1 Klingon with double strike and melee. With both on the battlefield at the start of your upkeep, every creature you control has double strike for the turn. Add Glory to the Empire!'s melee, which is +3/+3 when you attack all three opponents, and a 2/1 token swings as a 5/4, twice.
The box supplies the other keywords too: Imperial Hullbreachers has flying, Gnarling Targ has trample, and I.K.S. Negh'Var, Imperial Flagship gives your Klingons and Warriors vigilance, so Concerted Effort hands all of it to the whole team. It only reaches creatures you control when the upkeep trigger resolves, though. Worf's token, Rite of Ascension's tokens and anything you cast that turn don't get it.
Most upgrade lists cut Concerted Effort. In this deck, keep it.
Sins of the Father can drain from your own graveyard
Sins of the Father is a Saga. Chapter I makes each opponent sacrifice a nontoken creature, chapter II gives you a 2/1 hasty Klingon Warrior for each opponent, and chapter III exiles target player's graveyard, then each opponent loses life equal to the number of creature cards exiled this way. Target player, not target opponent. By chapter III, an aggro deck that trades creatures in combat and sacrifices them to Kor often has the biggest graveyard at the table, and eight creature cards in yours is eight life from each opponent. The catch is The Promise of Kahless, which wants that graveyard for itself.
The rule people will get wrong: tokens that enter attacking never attacked
Rite of Ascension's tokens enter tapped and attacking. They're attacking creatures, but for the purposes of trigger events and effects they never "attacked" (Comprehensive Rules 508.4). Three things follow from that:
- They don't add opponents to Battlefront's X. Send a 2/1 at one opponent and Rite makes one token. Point that token at a second opponent and Battlefront still counts one. You need a declared attacker at every opponent.
- They don't trigger "whenever this creature attacks." No melee bonus from Glory to the Empire! and no Shared Animosity trigger of their own.
- Own the Day and World at War don't untap them. Both untap only creatures that attacked this turn, so last combat's Rite tokens stay tapped. Combat Celebrant untaps all your other creatures, tokens included.
The trigger order helps you here. When you attack, Rite of Ascension and Shared Animosity trigger at the same time, and you choose their order. Put Rite's on the stack last. It resolves first, and by the time the Shared Animosity triggers resolve, the three new Klingon Warriors are attacking creatures that share a creature type with your attackers, so each attacker gets +1/+0 for them too.
The same rule covers two popular upgrades, Adeline, Resplendent Cathar and Mardu Ascendancy. Their tokens enter attacking, so they never raise X either. (Adeline makes a token for each opponent, attacked or not.)
Three more notes for the pilot
- Worf's cards are plays, not draws. You can play a land from among them if you haven't played one this turn, but every spell still costs mana. Leave some open for your second main phase. Qo'noS Quartermaster adds one mana of any color whenever it attacks, and that mana doesn't empty between steps and phases that turn.
- Koloth, Tribble Hunter gives every player two Tribbles at the beginning of your end step. All Tribbles get +1/+0 and are goaded, so they attack each combat if able and attack a player other than you if able, and they can't block. Yours are two more attackers for Battlefront. Theirs attack each other.
- The Promise of Kahless needs a body. It returns all other Klingon and Warrior creature cards from your graveyard, but only if you sacrifice a Klingon or Warrior as it resolves. After a wipe, recast Worf first: his token is a Klingon Warrior, and so is he.
Where it struggles
- Worf costs five, and the mana is slow. Six lands always enter tapped (Canyon Slough, Glittering Massif, Umbral Expanse, Temple of Malice, Nomad Outpost and Path of Ancestry), and three more fetch a basic land that enters tapped.
- It hands out cards. Ambassador K'Ehleyr and Alexander, Ship's Fool both make every player draw.
- Two of its sweepers hit you hardest. Pest Control destroys every nonland permanent with mana value 1 or less, which means your Klingon Warrior tokens, your Treasures and your Sol Ring. Vanquish the Horde destroys all creatures, in a deck that wants a wide board.
- Its protection is thin. Valorous Stance saves one creature, K'Vort-Class Raider gives your creatures hexproof during your turn, which stops targeted removal but not a wipe, and The Promise of Kahless only rebuilds if you still have a Klingon or Warrior to sacrifice.
Bracket 2 out of the box, and the $5 Equipment that changes that
Open the list in DeckCortex and Bracket Fit says Bracket 2, with a power level of 2.9 out of 10. It finds no Game Changers, no tutors and no two-card combos. The one thing keeping the deck out of Bracket 1 is Sol Ring, which counts as fast mana, and Bracket 2 allows one such card.
The combo engine also lists near misses, combos that are one card away, and four of them run through the same card. Combat Celebrant costs . If it hasn't been exerted this turn, you may exert it as it attacks, and when you do, you untap all other creatures you control and get an additional combat phase after this one. Give it a copy machine and it never stops. Helm of the Host ($5.03) creates a token copy of the equipped creature at the beginning of combat on your turn, not legendary and with haste. Equip it to the Celebrant: the new copy attacks and exerts, everything else untaps, and the next combat brings a fresh copy that hasn't been exerted. That's infinite combat phases, and every one of them triggers Worf, Martok and Rite of Ascension again.
Mirage Phalanx ($1.51), Splinter Twin ($7.41) and Kiki-Jiki, Mirror Breaker ($17.47) do the same with the Celebrant. With any one of the four in the list, the engine counts one complete two-card combo, and Bracket Fit moves the deck to Bracket 3. Bracket 2 allows none.
Upgrades in three stages
Every swap below replaces a card that does the same job. Prices are current Scryfall paper prices for each card's default printing in DeckCortex. The main-set Star Trek card is a preorder.
Stage 1: five swaps for $10.24, still Bracket 2
Two of these stop the deck from feeding the table, and two stop it from wiping its own board.
| In | Price | Out | Why | |---|---|---|---| | Windcrag Siege | $0.32 | Duelist's Heritage | Both are three-mana enchantments that make each attack count twice. The Heritage gives one attacking creature double strike. The Siege, set to Mardu, makes every ability that triggers because a creature attacks trigger an additional time: Worf exiles six cards instead of three, Kurn draws six (and you lose six life), Rite of Ascension makes six tokens. You lose the double strike. | | Skullclamp | $5.21 | Alexander, Ship's Fool | Both are repeatable card draw. Alexander's makes every player reveal and draw a card. Skullclamp draws only you two cards whenever the equipped creature dies, and its +1/-1 kills a 2/1 Klingon Warrior token the moment you equip it: for two cards. You lose a 3/5 with vigilance and haste. | | Phyrexian Arena | $2.94 | Ambassador K'Ehleyr | Both give you an extra card every turn. K'Ehleyr's Parley makes each player draw at the beginning of combat on your turn. The Arena draws only you a card in your upkeep, for 1 life. You lose a three-mana vigilant body that grows. | | Swords to Plowshares | $1.39 | Pest Control | Both are your cheapest removal. Pest Control destroys every nonland permanent with mana value 1 or less, and in this deck that's your own tokens, Treasures and Sol Ring first. Swords exiles one creature for . You lose the sweep. | | Elspeth, Sun's Champion | $0.38 | Vanquish the Horde | Both answer a board that has outgrown yours. Vanquish destroys all creatures, yours included. Elspeth's −3 destroys only creatures with power 4 or greater, so your 2/1 tokens survive it, and her +1 makes three 1/1 Soldiers every turn. She always costs six, while Vanquish gets cheaper with every creature on the battlefield. |
With all five in, the engine still finds no combo and no Game Changer, and Bracket Fit still says Bracket 2.
Stage 2: five swaps for $11.16, still no combos and no Game Changers
The second doubler, a main-set Worf, and three lands that stop costing you a turn.
| In | Price | Out | Why | |---|---|---|---| | Isshin, Two Heavens as One | $3.72 | Gnarling Targ | Both pay you whenever you attack. The Targ gives Klingons and Warriors +2/+0 and trample. Isshin does what Windcrag Siege does, and the two stack: every attack trigger now triggers three times, so Worf exiles nine cards in a four-player game. Kurn draws nine, and you lose nine life, so watch your total. He's a 3/4 for three instead of a 4/5 for five. | | Worf, Intelligence Contractor | $1.09 | Grilka, Widowed Warrior | Both borrow creatures to attack with. Grilka takes one creature for six mana. This Worf costs three and, for each opponent, takes up to one creature with mana value 3 or less until end of turn; they untap, become Warriors and gain haste. A borrowed creature attacking its owner counts for Battlefront like any other attacker. | | Haunted Ridge | $1.45 | Canyon Slough | Both are black-red dual lands. The Slough always enters tapped. The Ridge enters untapped once you control two other lands. You lose cycling. | | Shattered Sanctum | $2.14 | Umbral Expanse | Same deal in white-black. | | Sundown Pass | $2.76 | Glittering Massif | Same deal in red-white. |
With stages 1 and 2 in, the engine still finds no complete combo and no Game Changer, Sol Ring is still the only fast mana, and Bracket Fit says Bracket 2, with a power level of 3.0.
Stage 3: Bracket 3 on purpose, three Game Changers for $145.77
| In | Price | Out | Why | |---|---|---|---| | Smothering Tithe | $58.11 | Talisman of Indulgence | Both are mana. | | Teferi's Protection | $46.87 | Merciful Mandate | Both stop one bad turn from ending your game. The Mandate untaps your creatures and can end a combat phase. The Protection keeps your life total from changing and phases out everything you control until your next turn, so it also saves your board from a wipe. | | Jeska's Will | $40.79 | Painful Truths | Both refill your hand. Painful Truths draws up to three cards for that much life. With Worf out, Jeska's Will exiles your top three cards to play this turn and adds for each card in target opponent's hand. |
With all three, DeckCortex counts three Game Changers, and Bracket Fit says Bracket 3; Bracket 2 allows none. We'd stop at stage 2. Two doublers already turn every attack into nine cards off the top for Worf, and none of that is a Game Changer.
Is it worth $74.99?
Most of today's value is in the reprints. At current prices for their existing printings, the 66 reprints in the box add up to $127.67, basics included, led by Vault of Champions ($16.80), World at War ($12.46), Path of Ancestry ($11.73), Sword of Light and Shadow ($9.89) and Warleader's Call ($9.02). Of the new cards, only Worf has a preorder price so far, $9.95 for the foil. Don't count on any of that holding. A precon reprint tends to push those prices down, and a preorder price is an ask, not a sale. Buy it because you want to attack with it. It plays fine out of the box, and its weakest slots cost about ten dollars to fix.
Your call
If you want a deck that attacks from the turn Worf lands, this is one. Copy the list in DeckCortex, make the five stage-1 swaps for $10.24, and play it at a Bracket 2 table. If your pod plays Bracket 3, stage 2 adds Isshin and three untapped duals for another $11.16 without a single Game Changer. Whatever you add, run the combo scan before game night. If Helm of the Host shows up next to Combat Celebrant, your Bracket 2 deck isn't one anymore.
