Star Trek MTG Mechanics Explained: Dilemmas, Assimilate & Station

Star Trek releases on November 13, 2026, and its rules text leans on six terms. Five are new (assimilate, dilemma, strange new worlds, federation and beam me up) and one is back from Edge of Eternities (station, the Spacecraft mechanic). Here are the Star Trek MTG mechanics explained for Commander players: what each term does by the rules, where the reminder text stops short, and how each one plays in a four-player game. The Star Trek set page has every card, and our card-by-card spoiler roundup covers the factions. This post is about the rules.

Station is the ability on every Spacecraft, the artifact subtype that arrived with Edge of Eternities. The reminder text on U.S.S. Enterprise-D, Galaxy-Class reads: "Tap another creature you control: Put charge counters equal to its power on this Spacecraft. Station only as a sorcery. It's an artifact creature at 7+." Below that is a threshold line, "7+ | Flying, vigilance". Once the ship has seven or more charge counters it is an artifact creature with the power and toughness printed on the card and the abilities on that line. The counters stay. A Vehicle that you crew (tap creatures to animate it) is a creature only until end of turn; a stationed ship stays a creature from then on.

Four rules details decide how the mechanic plays. Station is an activated ability you can only use in your own main phase with nothing on the stack, so you cannot station in response to anything. Its cost taps another creature rather than using that creature's own tap ability, so a creature that entered this turn can be tapped for it, the same way crewing works. The number of counters is the creature's power when the ability resolves, so a pump spell cast before you activate, or in response, counts, and an opponent shrinking the creature in response costs you counters. And a ship that crosses its threshold can attack that same turn as long as you have controlled it since your turn began, because the rule about attacking looks at how long you have controlled the permanent, whatever it was at the time.

Until it crosses the threshold, a Spacecraft is a plain artifact. Creature removal and board wipes (wraths, the spells that destroy every creature) cannot touch it, and Romulan Bird-of-Prey has hexproof (it cannot be targeted by anything your opponents control) for exactly as long as it is not a creature, charging itself two counters every time you cast a noncreature spell. The moment it becomes a creature, every wrath hits it. The play that follows: station the ship to one counter short of its threshold while the table is holding wraths, and cross the line on the turn you attack.

The flagship is U.S.S. Enterprise-D, Galaxy-Class, three mana for an artifact that exiles the top card of your library, and lets you play it this turn, the first time each turn counters are put on it. The trigger does not care how many counters arrive, so a 1/1 Officer token stationing for one counter gets you the same card as a six-power creature. Warp Core finds a basic land for your hand when it enters, then, for and a tap, puts two counters on a Spacecraft at sorcery speed, once a turn since it taps, which triggers the Enterprise without tapping a creature. Lt. Cmdr. Geordi La Forge doubles every charge counter you put on an artifact, so one four-power creature puts the Enterprise online in a single station. Zefram Cochrane, Warp Pioneer has your Spacecraft enter with two extra counters and lets you cast one artifact spell from the top of your library during each of your turns.

Two more ships show the range of the mechanic. D-7 Battle Cruiser costs , and from three counters it makes a hasty 2/1 Klingon Warrior at the start of each of your combats (sacrificed at the next end step) while it is still a noncreature artifact; it only becomes a creature, with flying, at eight. Deep Space 9 costs , and its station reminder text has no creature threshold at all: it never becomes a creature. It exiles the top four cards of your library when it enters and at each of your upkeeps, puts every permanent card among them onto the battlefield, and at nine counters gives your creatures +3/+3. Captain Jean-Luc Picard ties the Officer tokens to the ships: tap seven untapped Officers and he puts any Spacecraft from your library onto the battlefield with seven counters already on it.

Assimilate is a keyword action, a verb a card tells you to perform, like investigate or explore. The reminder text on Borg Queen, Perfection Manifest, a mono-black mythic from Star Trek Commander: "Put it onto the battlefield under your control with a +1/+1 counter. It's a Borg artifact creature and loses all other creature types." Each card says where the creature card comes from. The Queen, six mana, takes a creature card from an opponent's graveyard when she enters. Death Is Irrelevant, an eight-mana enchantment, assimilates a creature card from any graveyard, yours included, at the beginning of each of your end steps. Borg Cube, a Spacecraft that costs less for each artifact creature you control (that is what affinity for artifact creatures means), assimilates a creature card it has exiled whenever it enters or attacks, and if there is none, exiles up to one target creature instead, ready for its next trigger.

Most of the card survives assimilation. It keeps its name, mana cost, colors, abilities and the legendary supertype. It gains the artifact type and the Borg creature type and drops every other creature type, so a stolen Dragon still flies but is no longer a Dragon for anyone's Dragon lords (creatures that pump every other creature of their type). It was put onto the battlefield rather than cast, so counterspells do nothing, its enter-the-battlefield triggers happen for you, and nothing that cares about casting notices. It also arrives with a +1/+1 counter.

The set's Borg payoffs are written for artifact creatures in general. Locutus, the One Who Speaks gives artifact creatures you control +1/+1, Borg Queen gives them +2/+0, Primary Unimatrix Adjunct gives them double strike, Command Subadjunct vigilance, Assault Drone +1/+0, and Death Is Irrelevant indestructible. A Myr, a Thopter token or a Construct gets all of it, and so does any Spacecraft that has crossed its threshold, which is the quiet overlap between the Borg and Starfleet halves of the set. Collective Drone has power equal to your artifact creature count, and Overflow Submatrix lets you cast an artifact creature spell from your graveyard once during each of your turns, entering with a finality counter (a creature with one is exiled instead of dying).

Two Commander-specific points. When a commander dies, its owner may send it to the command zone instead of leaving it in the graveyard, and nearly always does, so an opponent's commander is almost never there for Borg Queen to take; she takes the best creature that died, and at a four-player table that is three graveyards of candidates. Since her trigger needs a creature card in an opponent's graveyard, the Queen is at her best cast after the first board wipe. Resistance Is Futile, the Borg removal spell, is modal, which means casting it is also a dilemma, covered next.

No card in the set is a dilemma. Facing a dilemma is something you do: the reminder text on Seven of Nine reads "You face a dilemma as you choose one or more modes for a spell or ability." A mode is one of the bulleted options on a card that says "choose one", "choose two" or "choose one or more". Every charm, every command and every modal removal spell ever printed qualifies, which is why the dilemma payoffs are the set's most Commander-ready cards: Boros Charm, Kolaghan's Command, Cryptic Command, Austere Command and Collective Brutality all count, and most Commander decks already run a handful of cards like them.

The set's own modal spells include the five mono-colored Tests (Test of Conviction, Test of Priorities, Test of Loyalty, Test of Identity, Test of Courage), Impossible Choice, Consider the Prime Directive, Perils of the Past, Encounter the Unknown, Command Decision, Make It So, Stray from History, Rules of Acquisition and Dathon and Picard at El-Adrel. Modes on permanents count too. Captain James T. Kirk makes you choose a mode whenever he enters or attacks (one or more if your hand is empty). Subcommander T'Pol and Commander Raffi Musiker have modal enter triggers. The five lands Federation Outpost, Ni'Var Science Academy, The Unicomplex, Quark's Bar and Q Continuum offer a choice when they enter untapped, and they enter untapped once you control two other lands, so from your third land drop on, each of them is a free dilemma.

The payoffs: Seven of Nine draws a card per dilemma. Elim Garak, Simple Tailor drains each opponent for 2 per dilemma and Obsidian Order Operative for 1. Captain Benjamin Sisko makes a 1/1 Officer at your end step for each dilemma you faced that turn. The Caretaker triggers at the end step of any turn in which you faced a dilemma, opponents' turns included: an opponent exiles cards from the top of their library until a nonland card turns up, and you may cast it for free. Gabriel Lorca, Mirror Menace returns from your graveyard to your hand for whenever you face one.

Timing is the part to know cold. You choose modes while casting the spell, so the dilemma trigger goes on the stack on top of the spell and resolves first. Seven of Nine draws before Impossible Choice resolves, and she still draws if the spell is countered. Modes for an ability are chosen as the ability goes on the stack, with the same result. One spell is one dilemma however many modes you pick, so Kirk choosing all three options with an empty hand is a single trigger. Things that are not modes: picking a face of a modal double-faced card, paying kicker, choosing a value for X, choosing a color or a creature type, and casting one half of a split card.

Kobayashi Maru Scenario is the trap. At each of your upkeeps you choose a mode that has not been chosen yet, and the four modes are return an opponent's creature with mana value 3 or less to its owner's hand, draw two cards, make two Officers, and lose the game. Each of those upkeep choices is itself a dilemma, so for three turns it feeds Seven of Nine, Sisko and Garak on its own; then the fourth upkeep forces the last option, so the enchantment has to leave before it. Returning it to your hand resets it, because a card that leaves and comes back is a new object with no modes chosen. Tell Me What You See returns itself the same way whenever you face a dilemma, which is how it re-uses its enter trigger (an opponent chooses between letting you draw a card and losing 4 life).

Instants with modes are what make a dilemma deck work in a four-player game, and the set has one in every color: Impossible Choice in black, Consider the Prime Directive and Test of Priorities in blue, Perils of the Past and Test of Identity in red, Test of Courage in green and Set Phasers to . . . in white. Cast on an opponent's turn, each one has Seven of Nine drawing around the whole table instead of only on yours. One more thing for commander choice: Captain Benjamin Sisko's activated ability costs , and mana symbols in rules text count toward color identity, so he is a five-color commander whose deck can run every command in the game.

Strange new worlds is an ability word, which means the words themselves have no rules meaning; what follows them always counts the number of differently named lands you control. Five Forests are one name. Every nonbasic land is its own name. A Standard deck has to work to reach seven names, while a three-color Commander manabase has somewhere between twenty and thirty of them, so the mechanic is far stronger at our tables than in the format it was balanced for.

Captain Pike, Fullness of Time costs and has power and toughness equal to the count, and he lets you look at the top card of your library at any time and play lands from it, the same two lines as Augur of Autumn, which the Star Trek Commander decks reprint. The Traveler, a two-mana creature with reach and vigilance, has power equal to the count. Deep Space Scan draws that many cards and lifts your maximum hand size until your next turn. Branching Timeline reveals that many cards and puts every permanent among them onto the battlefield tapped. Ensign Pavel Chekov has each opponent exile that many cards from the top of their library and lets you play one land from each pile. Excalbian Gamemaster makes that many Officers, Pah-Wraith gives every creature you control that much extra power when it attacks, and Seven of Nine, Unassimilated draws a card at your first main phase, stops making you discard once you have five names, and at seven names can pay to become a 7/9.

Planet is the land subtype that feeds the count. The ten Planets (Andoria, Bajor, Cardassia Prime, Earth, Sector 001, Ferenginar, Orion, Qo'noS, Risa, Romulus and Vulcan) are two-color lands that enter tapped and gain you 1 life, one for each pair of colors. Final Frontier fetches a basic or a Planet onto the battlefield tapped. Saurian Explorer, Stable Wormhole, Genesis Effect and the five Anomaly lands (Artificial Anomaly, Gaseous Anomaly, Spatial Anomaly, Subspace Anomaly and Temporal Anomaly) make a Planet token named New Planet that taps for any color. Every one of those tokens has the same name, so the first New Planet adds one to the count and the rest add nothing. An Anomaly sacrifices itself, a uniquely named land, to make one, so the first Anomaly you crack breaks even and each one after it costs you a name; Genesis Effect makes you destroy a land of your own, so point it at a duplicate basic.

Two more traps. A fetch land (a land you sacrifice to search for another) or Evolving Wilds leaves the battlefield when you sacrifice it, so the count drops by one until the land it finds replaces it, and only recovers if that land is a new name. And since basic land names are the only duplicates most decks have, a mono-colored deck should know that Snow-Covered basics have different names from regular ones: an Island and a Snow-Covered Island are two names.

Federation is the second ability word, and it counts the number of creature types among non-Borg creatures you control. Each type counts once: Captain Pike, Fullness of Time alone is three (Human, Officer and Scout), and a second Human Officer beside him adds nothing. Tokens count, and Captain Jonathan Archer enters with Porthos, a legendary 1/1 Dog token, a type most decks never have. Borg creatures are excluded by type, and since assimilated creatures lose every type but Borg, the Borg deck gets nothing from any of this, by design.

Archer pays and taps to give a creature +X/+X at sorcery speed. Saavik, Stoic Student has flash and deals X damage to an attacking or blocking creature an opponent controls when she enters. Hoshi Sato, Exolinguist looks at the top X cards and keeps one. Infinite Diversity, nine mana, exiles an instant or sorcery from your graveyard and copies it X times, cast free. Starfleet Academy is a legendary land: and tap to add X mana of one color.

Now the clause, because it runs the opposite way from what most players will assume. A changeling is every creature type, and Borg is a creature type in this set, so a changeling is a Borg creature and federation ignores it. Universal Automaton adds nothing to X. Maskwood Nexus, which makes every creature you control every creature type, makes every creature you control a Borg and sets X to zero for as long as it is out, and the changeling copies Dominion Infiltration makes count for nothing either. The number has to come from real variety: Porthos's Dog, a Vulcan, a Klingon, a Cardassian, a Whale, and the Officers, Scientists and Pilots the crew cards carry two and three at a time. A deck of legendary crew members reaches a solid X by the midgame. A typal deck (one built around a single creature type) is the worst possible Federation deck.

Beam me up is a way to cast a card from your graveyard. The reminder text on Energize: "You may cast this card from your graveyard for if you also return a creature you control to its owner's hand. Then exile this spell." It behaves like flashback with an extra cost: cast it from the graveyard, pay the beam me up cost instead of the mana cost, return a creature to hand, and the spell is exiled after it resolves. The creature is returned as part of paying the cost, so nobody can respond to the return. But every beam me up card revealed so far is a sorcery (Energize, Open Communications, There's Coffee in that Nebula, Pure Energy, Adversary by Algorithm and Final Frontier among them), so this is a main-phase mechanic. None of the printed ones can save a creature from a removal spell. With Scotty, below, an instant in your graveyard can, but only during your own main phase.

When the creature has an enter trigger, the return is the reason to cast the spell. Spock, Always Your Friend digs four cards deep for a noncreature, nonland card. Hoshi Sato, Exolinguist, Saavik, Stoic Student, Worf, Intelligence Contractor, Salt Vampire, Subcommander T'Pol and Commander Raffi Musiker all enter with a trigger, and the last two are modal, so recasting them is also a dilemma. A token can be returned too; it stops existing in your hand, which is fine once an Officer token has done its job. Miles O'Brien, Transporter Ops bounces one of your own creatures or artifacts when he enters and draws a card at the end of any turn in which something returned to your hand from the battlefield.

Scotty, Miracle Worker is the engine: during your main phase every instant and sorcery card in your graveyard has beam me up for its own mana cost, with the rule that Scotty himself cannot be the creature returned. Marooned, a one-mana Aura, stops a permanent untapping (and taps it for an extra ) and says it cannot be beamed up, the set's own brake on the mechanic.

The Commander wrinkle: your commander can be beamed up. When a commander would go to your hand you may put it in the command zone instead, but you can also leave it in hand, and recasting it from there costs no commander tax (the extra per previous cast that applies only when you cast it from the command zone). Beam up a commander with an enter trigger, recast it for its printed cost, and the tax never climbs.

Dilemmas are the easiest to build well, because the cards that face them are the modal removal and card draw you were going to run anyway; the only new discipline is preferring a charm over a one-mode spell at the same cost. Strange new worlds is on by default in Commander and needs no help beyond keeping fetch lands to a minimum and cracking at most one Anomaly. Station needs a board of small creatures you are happy to tap, and the Officer tokens from Kirk, Picard, Sisko, U.S.S. Enterprise-A, Free Spirit and Make It So are exactly that. Assimilate wants a long game with full graveyards, which four-player games provide. Federation needs a deck built for it, because the non-Borg clause switches off the usual creature-type shortcuts.

Any two- or three-card combos the set made possible are indexed on the Star Trek combos page as they are found, and the Star Trek Commander precons have their own set page. If one of these mechanics ends up in your command zone, record the games: the deck gets its own rating from the first one, and after a few weeks you will know whether Seven of Nine is drawing enough cards to matter.
