* Winter's Curse in late game is pretty much the end for Meepo or any of his nearby allies. Natural counter for Winter's Curse like Linken's Sphere or Lotus Orb is meaningless to her if she can land it on one of Meepo's clones.
Additional:
* Meepo's clones usually gets grouped in teamfight making any of them ideal target for Winter's Curse, forcing Meepo to literally kill himself. Also, unlike other heroes he cannot protect himself with Linken's Sphere.
* While Meepo's clones are grouped up, Splinter Blast will hit almost every clone, slowing Meepo and making him easier to fight.

* Cold Embrace saves allies from dying in Duels.
* Winter's Curse turns Legion Commander's high damage against her allies, giving the enemy team little time to react.
* However, Winter Wyvern lanes very poorly against Legion Commander due to Press the Attack removing all the debuffs she can give. Winter Wyvern also has little chances of surviving if she gets Dueled herself.
Additional:
* Cold Embrace is very effective against Duel.
* Also, casting Winter's Curse at Legion Commander while an ally is in a Duel will stun her for most of the duration, possibly preventing lethal damage dealt to your ally. It can also turn her high-damage against her teammate.

* Each of Meepo's clones count as real heroes, meaning that an Echo Slam hitting them will deal catastrophic damage to Meepo and his team.
* Eathshaker's AoE stuns can interrupt Meepo's Poof cast animation.
Additional:
* Echo Slam will deal catastrophic damage against a cluster of Meepos and anyone nearby.
* Aftershock allows Earthshaker's abilities to potentially stun any number of Meepos for a fairly long duration, often enough to finish one off.

* Earthshaker's AoE stuns can save ally against Duel, forcing Legion Commander to spend Aghanim's Scepter or Black King Bar.

* Poof won't damage Medusa and she can use Stone Gaze to disable all of Meepo's clones.
* Mystic Snake will easily become the bane of Meepo early game.

* Mana Shield makes Medusa very hard to take down in Duels.
* Stone Gaze stops Legion Commander from Dueling altogether, regardless of who she targets.

* Great Cleave and God's Strength can take down Meepo and his clones very quickly.
* The lack of spell immunity for Meepo's clones makes them vulnerable to Storm Hammer.
Additional:
* Great Cleave will devastate Meepo's clones. Against a closely packed group, Sven does not even need to target the clone with the lowest health.

* God's Strength makes Sven one of the worst heroes to Duel.
* Storm Hammer can be used to interrupt Duels.
* Warcry gives a big boost in passive defensive ability with the active component to nearby allies.
* With the Aghanim Shard Warcry also gives nearby allies passive increases.

* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.

* Battery Assault's mini-stuns can severely disrupt Legion Commander's attack animation when she enters a Duel, potentially saving Clockwerk (or his allies) and possibly even giving him an edge in securing a win himself.
* Power Cogs pushes Legion Commander away from Clockwerk's allies when she enters a Duel.

* Heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, Dragon Knight, Meepo, Doom, Bounty Hunter, Dark Seer, Undying, Alchemist, Legion Commander.

* Atrophy Aura's percentage-based damage reduction greatly diminishes Legion Commander's overall damage output, even if she has won many Duels
* Legion Commander cannot get out the way of Firestorm because she is stationary.
Additional:
* Atrophy Aura makes it hard for Legion Commander to win Duels.
* Fiend's Gate can be used to save Underlord and his allies from a Duel or to intercept Legion Commander, because outside from Overwhelming Odds, Legion Commander has no other area-of-effect abilities.

* Tree Dance and Primal Spring allows him to chase a retreating Meepo.
* Boundless Strike gains critical strike bonuses and Wukong's Command can take down Meepo and his clones very quickly.
Additional:
* Monkey King can gain Jingu Mastery stacks on Meepo’s clones from Divided We Stand.
* Tree Dance allows him to sneak up on and gank a lone Meepo clone.

* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: Legion Commander, Lifestealer, Weaver, Wraith King

* Bulwark blocks the attack from Meepo and his clones.
* Spear of Mars & God's Rebuke prevents Meepo and his clones from initiation or escaping.

* Because Duel requires both combatants to face each other, Bulwark's effectiveness will be increased by a huge margin, which makes it much more difficult for Legion Commander to win any duels against him.
* Spear of Mars and God's Rebuke pushes Legion Commander away during Duels against allies.
Additional:
* Bulwark immensely mitigates Duel, even with bonus physical damage, as Bulwark scales by percentage. Mars can also buy time for a dueled ally by pushing Legion Commander away with Spear of Mars.

* Pangolier's arsenal deals heavy damage in a wide area, make him deadly even for a Meepo with a high magic resistance.
* Shield Crash can easily give him a ridiculous 80% damage resistance (Becomes 100% if Pangolier gets his +5% Shield Crash talent, Or there is 5 Meepos), resulting in a near unkillable Pangolier in a short amount of time.
* Rolling Thunder disrupts Meepo's initiation or escaping.
* Swashbuckle can hit all of Meepo clones.
* Lucky Shot can disarm Meepo's clones.
Additional:
* Shield Crash gains its damage reduction bonus from all Meepo clones, and can be used even when rooted, allowing Pangolier to gain a massive amount of damage reduction (even more than 100%).
* With too many clone running around during combat, it is almost impossible for Meepo to avoid Rolling Thunder or Swashbuckle.
* Still, remember that a lone Pangolier can never escape from a ganking Meepo.

* Lucky Shot can disarm Legion Commander and reduce her armor, which can reduce her chances of winning a duel. If an ally is targeted, Pangolier can simply use Swashbuckle to inflict it on her.
* If an enemy Pangolier casts a well-timed Rolling Thunder before Legion Commander can cast Duel, it might result in her chasing down Pangolier until his or her ultimate ends, whichever duration ends first, resulting in an open window for enemy allies to target Legion Commander, making her vulnerable and susceptible to any source of attacks. If Legion Commander has an Aghanim's Scepter in her inventory, the risk of wasting a solid 8 seconds would result in a futile duel.
* Dueling Pangolier is normally a mistake, Pangolier can disarm you in the duel, and potentially gain some Duel damage, Only duel Pangolier if at least 1 ally is nearby, and he is on low health, And even then, be wary, A good duel can easily turn against you with one Lucky Shot (Due to Lucky Shot lasting 4 seconds).
Additional:
* Swashbuckle can be used to disarm Legion Commander while she is Dueling an ally, granting her opponent a considerable advantage, Lucky Shot lasts 4 seconds at most wasting Legion Commander's entire Duel, (Or half, if Legion Commander has the Scepter).
* Legion Commander will try not to duel Pangolier alone, as she will almost inevitably lose, thanks to Lucky Shot's disarm, If Legion Commander wants to duel a Pangolier, she must be with atleast a teammate, and if she has her scepter, 3 or 4 teammates.
* Legion Commander is often with her allies, allowing you to rack up some considerable damage resistance with Shield Crash.

* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.

* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; Spirit Breaker, Legion Commander, Axe, Puck, and Slardar.

* Troll Warlord can root and deal a lot of damage to a single Meepo while lifestealing through the assault from the other Meepos. Meepo needs expensive items like Ethereal Blade or Heaven's Halberd to be able to fight him.

* Troll Warlord's melee bash and high attack speed can often help him and his allies win Duels against Legion Commander.

* Meepo lacks the disengages to escape a well-timed Echo Stomp, in particular if Elder Titan is his current target.
* Clones are counted as heroes, increasing massively the power of Astral Spirit's buffs, including Aghanim's Scepter's spell immunity buff.
* Meepo relies heavily on high agility and his mediocre strength gain makes him a very prized target for Natural Order.
* Meepo and his clones like to group up to hunt and kill in teamfights or ganks and can be easily disabled together with Echo Stomp.
Additional:
* Echo Stomp can completely disable multiple Meepos for 5 seconds.
* Astral Spirit will affect Meepo clones, as they don’t count as illusions. Elder Titan can receive a massive amount of damage, armor and movement speed from each Meepo.
* With Natural Order, Elder Titan’s mere existence causes Meepo to be disadvantaged, due to the aura that completely negates his base armor and magic resistance. Combining Astral Spirit with Natural Order allows Elder Titan to easily kill any Meepo within a second, depending on how much damage he gains from Astral Spirit. This is highly detrimental for Meepo as he is prone to buying items that grant agility like Disperser and Eye of Skadi.
* Earth Splitter deals over 30%/40%/50% of each Meepo’s max hp, and is even stronger if the Meepos are near Elder Titan due to Natural Order.

* With Nether Swap, Vengeful Spirit can isolate one of the Meepos, making him an easier kill for the team.
* Her Magic Missile gives her an easy way to cancel Meepo's Poof, preventing isolated Meepos from fleeing.

* Tether helps Io escape from Earthbind even if Meepo has Blink Dagger.
* Io's Spirits can pressure Meepo while laning and will usually hit at least one of his clones.

* Tethered heroes are much harder for Legion Commander to kill in Duels.
* Relocate can cancel Duels and save allies.

* Astral Imprisonment prevents Legion Commander from killing her opponents in Duels.
Additional:
* Outworld Destroyer can save an ally hero caught by Duel with Astral Imprisonment, and he can inflict heavy damage on Legion Commander with Arcane Orb to aid his ally. However, if he gets caught, he is unlikely to survive the duel, due to his lack of durability.

* Shallow Grave prevents Legion Commander from killing her opponents in Duels.
* Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.

* If he isn't broken (break), Abaddon can use Borrowed Time to waste Legion Commander's Duel, As Borrowed Time has a shorter cooldown, Legion Commander can't win duels, effectively reducing her targets by one, Duel also means that Borrowed Time heals Abaddon for the duration of the duel, as Legion can't stop attacking.
Additional:
* Aphotic Shield and Mist Coil makes it hard for Legion Commander to kill Abaddon's teammates in Duels.
* Borrowed Time makes Abaddon nearly impossible to kill in Duels, and often replenishes much of his health because Legion Commander cannot manually stop attacking during Duels.

* Solar Guardian can save allies who are being dueled and will interrupt her Duel initiation.

* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.

* Invoker's spells will disable and destroy Legion Commander while she's locked in a Duel.

* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.

* Bane has powerful single-target abilities that can help his allies win Duels, or at least cripple Legion Commander for the duration.
* Nightmare can waste Duel's entire duration as the dueled units transfer the Nightmare back and forth. This may be prevented if a non-Dueling unit attacks the Nightmared Dueler.
Additional:
* Enfeeble, Nightmare and Fiend's Grip all prevent Legion Commander from winning Duels, especially when Bane has Blink Dagger.

* Dark Seer can take great advantage of Divided We Stand by putting an Ion Shell on a clone in order to harass them effectively.
* Vacuum can take a single Meepo and disable him for Dark Seer and his teammates to take out.

* Fury Swipes can give Ursa the edge in Duels.
* Enrage's instant cast time allows it to be used before Legion Commander initiates a Duel, causing Ursa to take almost no damage for a brief period of time.
* However, Duel stops Ursa from casting Enrage at the most critical moment

* Pulse Nova deals an insane amount of damage in an area around him, which can quickly wear down Meepo clones.
* Leshrac can catch multiple Meepos in Split Earth and follow up with the rest of his area damage spells making Meepo unable to get close to Leshrac.
* Diabolic Edict is a strong ability that can wear down a lone Meepo clone quickly.

* Purification prevents Legion Commander from killing her target, and will always hit her during Duels.
* Guardian Angel completely wastes Duel's duration and can save an ally across the map when upgraded with Aghanim's Scepter.
Additional:
* Both Guardian Angel and Purification are perfect counters against Duel.

* Every Meepo clone adds to Thirst's bonuses.
* Bloodseeker can chase down retreating clones when Meepo tries to cycle weaker clones away from combat.

* X Marks the Spot is good to prevent a single meepo from escaping from a deadly situation.
* Tidebringer, Torrent and Ghostship destroys Meepo's clones.
Additional:
* Tidebringer's cleave damage can wear down Meepo's clones quickly. It can also give Meepo problems in the lane, due to his melee range and initially low health pool.
* Ghostship and Torrent can effectively disable Meepo while dealing heavy damage.
* X Marks the Spot prevents attempts to escape using Poof.

* Paralyzing Cask can save ally from Legion Commander Duel's until she purchases Aghanim's Scepter.
* Voodoo Restoration can heal Witch Doctor allies from Duel's.
* Death Ward can help Witch Doctor allies from winning Duel's, if, he is not a target.

* If Meepo ganks Lion with Poof and Earthbind, he will be an easy target for Earth Spike & AoE Hex from his level 25 talent.

* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion

* Flak Cannon and Call Down will shred Meepo's clones.
* Homing Missile can catch and single out retreating Meepos, making them an easy kill.

* Casting Bramble Maze on top of Meepo guarantees a root, as it is nearly impossible to leave the thorns with all of Meepo's clones.
* Terrorize and Cursed Crown offer great disables against the grouped Meepos and can prevent them from using Poof to escape.

* All of Jakiro's skills are Area of Effect, which can easily affect all Meepos in a targeted area.

* Meepo is vulnerable to area damage and disables from Magnus himself as well as his team through Empower.

* Static Link drains Legion Commander's accumulated damage, effectively neutralizing her overall primary advantage, and prevents her from winning Duels.
* Storm Surge's movement speed buff makes Razor and his allies harder to catch and initiate.
* Eye of the Storm, if used beforehand, will always hit Legion Commander during Duels, due to her forced proximity. This drastically lowers her survivability during Duel.

* Because multiple Meepos tend to clump up, they present an easy target for Timbersaw's many area abilities.
* Although be careful since Timbersaw cannot use Timber Chain to escape if rooted from Earthbind.

* Light Strike Array can catch Meepo and his clones off-guard if he tries to gank Lina with Earthbind & Poof.
* Laguna Blade can quickly kill Meepo and his clones before they escape with Poof.

* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector

* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.

* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.

* With armor items like Solar Crest or Assault Cuirass combined with Bash of the Deep, Slardar can easily tank the Duel, If not dueled himself, he can drop Legion Commander's armor during duel and/or buff his teammate and save them, leaving her only the choice of dueling supports which can also be saved with fast Blink into Slithereen Crush.

* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.

* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector

* Shadow Fiend's Requiem of Souls not only slow all Meepos, but it can also kill the weakest Meepo instantly if the ultimate is released at the right position and time.

Additional:
* Shadow Fiend can easily focus down and kill one of the Meepos.
* The amount of damage from Shadow Fiend's AoE spells makes Meepo vulnerable in every aspect.

* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).

Additional:
* Walrus PUNCH! makes Legion Commander lose Duel easily, especially when she doesn't have Blade Mail. Tusk can also snowball dueled allies, preventing them from taking damage for a large portion of the duel's duration.

* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.

Additional:
* Burrowstrike can stun multiple Meepos, making them vulnerable targets.
* Epicenter and Sand Storm's AoE damage ensures all Meepo clones get damaged, making it hard for Meepo to choose which one to flee as all are taking damage at the same rate.
* Just be aware when using Sand Storm to escape, as Meepo has good AoE damage and disables, which, as explained in the "Bad Against" section, works well against an invisible Sand King.

* Heroes that have doubles or clones such as Arc Warden, Meepo or Lone Druid are vulnerable to Muerta's Gunslinger.

* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.

* Tiny's Avalanche affects all Meepos and Toss can send a singular Meepo into death.

Additional:
* Avalanche and Toss prevents Meepo's from using Poof to escape.
* Tiny doesn't need to target the weakest clone while he is affected by Tree Grab.

* Enchantress's Untouchable slows down Meepos attacks and Impetus can deal heavy pure damage to a single Meepo, however once Meepo has closed the gap she is an easy target for Poof.

* Untouchable makes Enchantress one of the hardest heroes for Legion Commander to Duel against, as her attack speed will be significantly slowed for the duration, even with any form of spell immunity.
* Meanwhile, when Enchantress is not a target, Enchantress can use both Impetus and Enchant on Legion Commander to help her ally win the Duel.

* Besides Lone Druid and Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.

* Gravekeeper's Cloak protects Visage from Legion Commander's attacks for most of Duel's duration.
* Chain stuns from Visage's familiars prevents Legion Commander from winning Duels.

* Fate's Edict prevents Legion Commander from attacking for a few seconds, potentially saving Oracle's ally.
* Fortune's End dispels Press the Attack's healing and attack speed buff, as well as the movement speed bonus from Overwhelming Odds.
* False Promise protects allies and prevents Legion Commander from winning Duels and gaining bonus damage.
Additional:
* Provided that the enemy team does not have an Axe, Oracle can guarantee that his ally survives for the duration of the Duel with False Promise and has decent nuke potential to help ally to win a Duel. He can also disarm Legion Commander with Fate's Edict.
* Oracle can dispel enemy buffs like Overwhelming Odds and Press the Attack with Fortune's End.

* Fatal Bonds links the Meepos together, which combined with area of effect damage or Cleave will be devastating.

* Decrepify on either hero stops Legion Commander from completing a Duel, and dissuades her from initiating Duels on ethereal allies.
* Life Drain can help Pugna's teammates win a fight, either by killing Legion Commander or replenishing her target's health.
Additional:
* Decrepify prevents Legion Commander from attacking allies during Duel, regardless if it's used on her or on the ally .
* Pugna can easily cast Decrepify, Nether Blast and Life Drain on Legion during the 4/4.75/5.5/8 seconds of duel

* Poof combo puts all of the Meepos very close together, making them vulnerable to Frost Blast's AoE slow and multiple bounces from Chain Frost.

* Aggressively Poofing and Earthbinding is not going to end well against Venomancer, as he will be an easy target for Noxious Plague.
* Venomancer's constant slows greatly reduce Meepo's mobility.

* Mystic Flare can easily burst down Legion Commander while she is Dueling.

* Meepo is quite fragile in the early game and can be easily taken down by Flame Guard's and Searing Chains' damage. Later on, Meepo is very vulnerable to Sleight of Fist's damage due to Battle Fury's cleave on multiple Meepos.
Additional:
* Sleight of Fist combined with Battle Fury, Maelstrom and Daedalus will allow Ember Spirit to make a quick work of Meepo if his clones are crowded around each other.
* Searing Chains interrupts Meepo's initiating because Meepo's clones do not have spell immunity.

* Reactive Tazer can lock multiple Meepos in place and prevent them from Poofing.
* Proximity Mines, Sticky Bomb and Blast Off! can deal heavy magic damage to multiple Meepos.

* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: Arc Warden, Keeper of the Light, Riki, Tinker

* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: Arc Warden, Keeper of the Light, Riki, Tinker

* Void Spirit can dodge Earthbind with Dissimilate and Astral Step, giving him a good chance to escape. If he gets caught anyways, Resonant Pulse allows him to retaliate.

* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: Arc Warden, Keeper of the Light, Riki, Tinker

* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion

* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector

* Magnetic Field prevents Legion Commander from getting wins with Duel.
Additional:
* Magnetic Field prevents Legion Commander from easily gaining wins with Duel.

* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.

* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).

Additional:
* Disruption can save allies and mess up an initiation from an enemy Legion Commander. Using Disruption on your ally that is affected by Duel will leave her totally exposed without the benefit of the life steal from Moment of Courage. A precise decision to Disrupt Legion Commander or her victim is crucial to waste Duel's potential.
* Demonic Purge cannot be dispelled by a hard dispel from Press the Attack, which in turn can be dispelled by your ultimate.

* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.

* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.

* Heroes with global abilities can give Legion Commander's opponent an edge in Duels from anywhere on the map: Nature's Prophet, Ancient Apparition, Zeus, Invoker, Treant Protector

* Heroes who can hide the Dueled target (Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter etc).

Additional:
* Legion Commander relies on her powerful attack and her Duel to be effective. But if Phoenix gets the jump on her first, she can find herself severely slowed, taking heavy damage, and find herself unable to Duel a burning Supernova.
* It must be noted that Press the Attack will both dispel the attack slow of Fire Spirits and grant her or whoever she targets bonus attack speed. This allows her to easily destroy a Supernova if caution is not taken to prevent this from occurring. As such, it would be a better decision to simply avoid a farmed or skilled Legion Commander instead of attempting to overpower her.
* If an ally is caught by Duel, Phoenix can use Sun Ray to heal the ally and damage Legion Commander, possibly swinging the Duel in their team's favor. Or with Aghanim's Scepter, Phoenix can save an ally from dying in Duel with Supernova and cancel the Duel as well.

* Song of the Siren lasts long enough to prevent a successful Duel (but only if Naga wasn't the target).

* Flaming Lasso is the perfect tool to isolate a single Meepo and focus him.

* Focus Fire can quickly attack target Meepo or clones instanly. Additionally, Windranger can use combinated Shackleshot and Focus Fire since Poof wrong landing and stunned from Shackleshot affected Meepo and clones collateral damege from Focus Fire.
* Escaping from Windrun make Earthbind roots can not reach.

* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden).

* A well-timed Eclipse before a Duel usually prevents Legion Commander from winning Duels, if Luna is the target.
* Meanwhile, when Luna is not a target, Eclipse and Lucent Beam can also help an ally win a Duel against Legion Commander.
* However, skilled Legion Commander will always buy a Black King Bar to block Eclipse and Lucent Beam or Aghanim's Scepter to reduce it's damage.
Additional:
* A well-timed Eclipse before a Duel usually prevents Legion Commander from winning Duels if Luna is the target. Luna can also buy Linken's Sphere to block Duel.
* Meanwhile, when Luna is not a target, Eclipse and Lucent Beam can also help an ally win a Duel against Legion Commander.
* Bear in mind, however, that skilled Legion Commander will always buy a Black King Bar to block Eclipse and Lucent Beam or Aghanim's Scepter to reduce their damage.

* Viper Strike prevents the lifesteal from Ransack.
* Meepo and his clones have a lack of magic resistance, so they're vulnerable to Poison Attack & Viper Strike directed onto one clone.

* Quill Spray usually hits Meepo's clones, although Bristleback cannot turn his back when rooted with Earthbind.

* Melee heroes who rely on summons, illusions, or clones will trigger Counter Helix more often, thus taking more damage: Meepo, Lycan, Phantom Lancer

Additional:
* The combination of Counter Helix and Berserker's Call can disable multiple Meepos and deal heavy area damage.
* Axe's natural high survivability makes it difficult to burst him down with Poof or chip away at his health with Ransack.

* Lifestealer is not affected by Earthbind or Poof during Rage, making him a difficult target to work around.

* Wraith King's Reincarnation allows him to severely punish Legion Commander after he revives, as her abilities are on cooldown. Legion Commander is still awarded a Duel win if Wraith King reincarnates.

Additional:
* Wraith King makes a poor Duel target, as he can be already quite hard to bring down once, and then you have to worry about his second life.
* However, even if Legion Commander does win the duel when Reincarnation is off cooldown, she still receives the permanent victory damage bonus because taking down Wraith King's first life still counts as a "kill".
