How to build Constable Odo

A creature held down by stun counters never leaves the battlefield, so if it is a commander its owner has no way to cast it again. Every flicker in this list hands Odo that choice once more: lock something down for two more turns, or take two Clues.

A stunned commander stays where its owner cannot recast it

Most removal pointed at a commander is a loan. Destroy it or exile it and its owner moves it to the command zone, then casts it again on their next turn for two mana more than last time. The stun mode does something no removal spell can. The creature stays on the battlefield, tapped, and its owner has no say in when it comes back, because it never went anywhere.

Two stun counters cost a creature two of its controller's untap steps. Each time it would untap, a counter comes off instead, so it sits through two untap steps and is free again on the third. Until then it cannot attack, cannot block and cannot use any ability with the tap symbol in its cost. Any card that untaps it in between runs into the same rule and only takes a counter off.

What the counters leave alone matters just as much. Static abilities work on a tapped creature, and so does any trigger that needs no attack. A commander whose value is an upkeep trigger or a cost reduction barely notices, and that is the job for Swords to Plowshares and the other removal in the list. Point the stun at whatever attacks, blocks or taps for value, and keep the exile for the commander that does its damage sitting still.

Each end step flicker adds two counters, and each of their untap steps takes one away

Four permanents in the core list exile and return a creature at the beginning of your end step: Teleportation Circle, Soulherder, Conjurer's Closet and Thassa, Deep-Dwelling. Aim any one of them at Odo, choose the stun mode, and pick the creature you stunned the turn before.

The count then only goes one way. You add two counters at your end step, its controller's untap step removes one, and so the pile grows by one every time the turn comes back round to you. For as long as the engine stays on the table, that creature does not untap again.

The pile is a reserve as well as a lock. Three rounds on the same creature leave three counters on it after its owner untaps, which is three more untap steps it sits through with no further help from you. Spend those three end steps on Clues and it is still tapped when you come back to it.

Fear of Sleep Paralysis turns every stun counter into a permanent one

Fear of Sleep Paralysis has one line that changes what the commander is. Stun counters cannot be removed from permanents your opponents control. A stunned creature still tries to untap, the rule still says to remove a counter instead, the counter cannot be removed, and so the creature stays tapped.

With that enchantment out, the stun mode is a lock with no end date, and against a commander it beats any removal in the format for the reason above. The enchantment adds a counter of its own whenever it or another enchantment enters, and it is a 6/6 flyer, so it is never a dead draw when the board is quiet. If it leaves, nothing untaps all at once. The counters are still there and start coming off again, one per untap step, which buys a few turns to find another flicker.

Tap an attacker in its owner's beginning of combat, never once it has attacked

Tapping a creature that is already attacking does not take it out of combat. It deals its damage anyway, and the stun counters only matter from the next untap step on. To stop an attack, Odo has to enter before attackers are declared, which on an opponent's turn means the beginning of combat step.

Six cards in the list can put him there. Ephemerate, Momentary Blink, Ghostly Flicker and Restoration Angel flicker him at instant speed. Deadeye Navigator does it for two mana once the two are paired. Sally Sparrow lets you cast creature spells as though they had flash, and that includes Odo himself out of the command zone. Floodpits Drowner, Cryogenic Stasis and Out Cold do the tapping without him.

Disorder in the Court is the one card here that still works after attacks are declared, because it exiles rather than taps. Set X to two and target the attacker and Odo together. The attacker leaves combat, two Clues arrive straight away, both creatures come back tapped at the next end step, and Odo's trigger can then put two stun counters on the creature that has just returned.

Doubling Odo's trigger buys a second choice of mode, not the same one twice

Panharmonicon, Roaming Throne and Elesh Norn, Mother of Machines each make Odo's trigger happen twice when he enters. Two triggers are two separate abilities, each with its own choice of mode, so a doubled Odo locks a creature and makes two Clues on the same entry instead of picking between them. Elesh Norn also stops your opponents' enters triggers altogether, which matters most against the other blink deck at the table.

Name Detective on Roaming Throne. Odo is a Shapeshifter Detective with no changeling text, so the throne sees him under either type, but Detective also covers Ezrim, Agency Chief, Alquist Proft and Sally Sparrow. Dominion Saboteur takes on Odo's types when it copies him, so it is covered by either name. Shapeshifter would catch Odo and his copies and nothing more.

Erdwal Illuminator and Academy Manufactor multiply the other side. Erdwal adds a third Clue the first time you investigate each turn, and Manufactor turns every Clue you would create into a Clue, a Food and a Treasure. One entry with both on the table is three of each, which pays for cracking the Clues it just made.

Uncracked Clues become 6/6 Plants once Tangletrove Kelp is out

Clues are the card draw in this list, and on a first read they look like its weak spot, because only seven cards in the list are draw spells in the usual sense. Count the cards that investigate instead and the picture changes. Odo alone is two cards an entry, and behind him sit Ethereal Investigator (three Clues at a four player table), Ezrim (two), Confirm Suspicions (three), Out Cold, Disorder in the Court, Alquist Proft, Sally Sparrow and Thraben Inspector. Each Clue is two mana for a card at instant speed, which suits a deck that keeps mana open for flickers and counterspells and needs a use for it on the turns nothing happens.

Tangletrove Kelp changes what a Clue left on the table is worth. At the beginning of each combat, on your turn and on everyone else's, every other Clue you control becomes a 6/6 Plant until end of turn. Eight Clues are forty eight power when you attack and eight blockers when they do. A Clue made this turn cannot attack, because it has not been under your control since the turn began, so it is the Clues from an end step flicker that swing on the following turn.

That puts a choice into the late game that the early game never asks. Crack Clues for cards, or keep them as bodies. Once Kelp is in your hand, stop cracking.

Four cards that get paid for a tapped creature

The stun mode looks like the one that costs you, since the Clue mode makes two cards and this one makes none. Four cards in the list pay you back for it.

Sharae of Numbing Depths draws a card the first time each turn you tap one or more untapped creatures your opponents control, and the stun mode does exactly that whenever its target was untapped. Floodpits Drowner shuffles itself and any creature with a stun counter on it into their owners' libraries for , which turns a two turn lock into a permanent answer. Its owner may send a commander to the command zone instead, so save the Drowner for everything else. Shuttle Crew deals 4 damage to a tapped creature an opponent controls when it enters, and a stunned creature is a tapped one.

Norn's Choirmaster proliferates whenever your commander enters or attacks. Put its trigger on the stack first so that it resolves after Odo's, and the creature he has just stunned gets a third counter along with every other stunned creature on the board. Karn's Bastion is in the land count for the same job, at a time.

Thirty five of the thirty six lands can pay for Odo

A source count reads Odo's as two white pips and two blue pips at the same moment, and neither demand is real. Each hybrid symbol takes white or blue, so any two coloured mana pays for him, and thirty five of the thirty six lands here make or fetch one colour or the other. Karn's Bastion is the only one that cannot, and it is there to proliferate.

The pressure that is real comes from the rest of the list. Ezrim, Agency Chief costs , the hardest colour requirement in the list, and at two mana Knight of the White Orchid wants while Counterspell wants . That is why the split sits so close to even, at twenty eight blue sources against twenty seven white once the four rocks that make coloured mana are counted, from ten Islands, nine Plains and sixteen other lands that make or fetch one colour or both.

Three Game Changers set the floor at 3, and the lock is what to mention at the table

Smothering Tithe, Rhystic Study and Teferi's Protection are the three Game Changers in the core list. Three is the most bracket 3 allows, and they are why the floor sits there.

The thing worth saying out loud before a game is on no list at all. With Fear of Sleep Paralysis and an end step flicker on the table, a creature Odo stuns never untaps again, and a bracket 3 pod has not signed up for that just because nothing in the deck is restricted. The lock involves no combo and does nothing to a noncreature threat, so the deck belongs at bracket 3, but tell the table it is in there.

The core list

Hover over any card name to see it. Nobody sells the five Star Trek cards yet, so they show no figure. Each of the others is shown at the cheapest paper copy on sale, and that copy is also the one the hover shows you.

Load into the deck builder Copy decklist

“Load into the deck builder” opens this list in your account, ready to edit or save. “Copy decklist” gives you plain text for Moxfield, Archidekt or Arena, with no account needed.

The budget rung keeps Panharmonicon, and the bracket 4 rung pairs Deadeye with Peregrine Drake

The two rungs pull on different parts of the list. Odo, the flicker spells, the stun pieces and the Clue engine sit in all three versions. What moves is how often an entry counts twice, how fast the deck reaches the cards that matter, and whether it ever stops.

The budget rung is fourteen swaps, and it brings the minimum from $430 down to $98. The three Game Changers leave, and so do Roaming Throne, Elesh Norn, Mother of Machines and Thassa, Deep-Dwelling, along with Otawara, Soaring City, Flooded Strand and the two dearest dual lands. Panharmonicon stays, and so do Fear of Sleep Paralysis, Floodpits Drowner, Sharae of Numbing Depths, Erdwal Illuminator, Tangletrove Kelp and every flicker spell, so a stunned creature still never untaps and a pile of Clues still turns into an army.

Strionic Resonator comes in as the cheap way to repeat a trigger, and here it is worse in one exact respect. A copy of a triggered ability keeps the mode chosen for the original, so a copied Odo trigger gives you two locks or four Clues, never one of each. Panharmonicon makes a second trigger with a second choice, which is why it is the doubler that survives and the Resonator only covers part of the gap.

The protection changes character on the way down, and in one respect for the better. Teferi's Protection phases your board out, which saves it and triggers nothing. Eerie Interlude and Ghostway exile your creatures and bring them back at the next end step, so a sweeper answered by either of them also hands Odo a fresh entry. What the cheaper list gives up is pace. Without Thassa the end step flickers are Teleportation Circle, Soulherder and Conjurer's Closet, Cloudshift and both replacement protection spells are one shot, and the second choice of mode now rides on a single artifact.

The bracket 4 rung is nine swaps, and one of them changes the deck's ending. Peregrine Drake untaps up to five lands when it enters. Paired with Deadeye Navigator, which is already in the core list, it can be exiled and returned for as often as you like, and each return nets three mana, so the mana has no ceiling. Float as much as you need, decline the pairing on the last return, flicker Odo once with Ephemerate or Momentary Blink, and pair Deadeye with him instead. From then on every is another entry: stun counters on every creature your opponents control, and as many Clues as you want. Crack enough to find Tangletrove Kelp, and the rest are 6/6 attackers on your next turn against a board where nothing untaps.

The other eight swaps find and protect that. Enlightened Tutor fetches Fear of Sleep Paralysis, Thassa or Panharmonicon, Mystical Tutor fetches a flicker spell, and Fierce Guardianship and Force of Will keep the loop alive through a counterspell. Mana Vault and The One Ring are speed and cards. Grand Arbiter Augustin IV takes a mana off every white spell and every blue one, so Odo, who is both, costs two less, while every opposing spell costs one more. Cyclonic Rift is the overload for the turn the lock has not reached far enough. With eleven Game Changers aboard, the floor is 4 and the minimum price is $835. Nothing in it is banned and nothing takes an extra turn, and the loop needs Deadeye Navigator and Peregrine Drake on the table at the same time, so the table always knows where to aim its removal.

FAQ

How long do Constable Odo's stun counters keep a creature tapped?

Two of its controller's untap steps. Each time a stunned creature would untap, one counter comes off instead, so with two counters it stays tapped through two untap steps and untaps as normal on the third. A card that untaps it in between only removes a counter too. This list flickers Odo to add two more each time, which is how one creature is kept down for the whole game.

Is Constable Odo legal in Commander?

Yes, from 13 November 2026, which is Star Trek's release date. A deck checker run sooner than that refuses him and the other four cards here from that release, because legality is tracked card by card and those five are not on sale yet. The other ninety five are legal today.

Does Panharmonicon let Constable Odo use both modes?

Yes. Panharmonicon makes his enters trigger happen twice, and each trigger is its own ability with its own choice of mode, so a single entry can stun a creature and investigate twice. Copying the trigger works differently. A copy made by Strionic Resonator keeps the mode the original chose, so it repeats that mode instead of giving you the other one.

Is Constable Odo a changeling?

No. He is a Shapeshifter Detective with no changeling text, so those are his only two creature types, whatever the character manages on screen. Cards that care about a type see him as one of those two. On Roaming Throne this list names Detective, which also covers Ezrim, Agency Chief, Alquist Proft and Sally Sparrow.

Can Constable Odo stop a creature that is already attacking?

Not with the stun mode. Tapping an attacking creature does not remove it from combat, so it still deals its damage. Flicker Odo during the beginning of combat step, before attackers are declared, and the stunned creature cannot attack at all. Once attacks are declared the answer is Disorder in the Court, which exiles the attacker and so does take it out of combat.

How much does this Constable Odo deck cost?

At least $430 for the core list, $98 for the budget rung and $835 for the bracket 4 rung. Each figure is a minimum, because nobody sells the Star Trek cards yet, so none of the three totals covers all hundred cards. Everything already in print is counted at the cheapest paper copy on sale.

Can Constable Odo be a Pauper Commander?

Yes, once Star Trek is out. Pauper Commander takes an uncommon creature as its commander, and Odo is printed at uncommon. This list is not a pauper list, though, since that format also wants the other ninety nine to be commons, so a pauper version starts again from the flicker and investigate commons.
