Tiny
* Dual Breath and Liquid Fire reduces Tiny's already abysmal Attack Speed.
* If Tiny 
Tosses a hero onto Jakiro, he can react with Ice Path, and potentially Macropyre.
* Tiny's 
Avalanche is easily countered with Ice Path.
* As Tiny has a very high Health, Liquid Frost is particularly effective against him.
Shadow Shaman
* Heroes with channeling spells are very easy targets for Jakiro's abilities: 
Crystal Maiden, 
Dawnbreaker, 
Enigma, 
Pudge, 
Shadow Fiend, 
Shadow Shaman, 
Warlock.
Tiny
* 
Chaos Bolt and 
Reality Rift makes Tiny's low mobility non existent.
* 
Chaos Strike means Chaos Knight will most likely survive longer in a duel between the two because Tiny has much lower attack speed.
* Chaos Knight has a 3.2 strength growth, making him one of the most tanky heroes and a very difficult target for Tiny to burst.
Shadow Shaman
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: 
Bane, 
Beastmaster, 
Bloodseeker, 
Clockwerk, 
Doom, Shadow Shaman.
Tiny
* Long ranged heroes like 
Sniper or 
Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Shadow Shaman
* Sniper can easily destroy 
Mass Serpent Wards from long range.
Tiny
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as 
Silencer, Drow Ranger and 
Death Prophet.
Tiny
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, 
Tiny and 
Undying have a very hard time killing Familiars.
Shadow Shaman
* Due to their high attack speed, 
Summon Familiars will destroy Mass Serpent Wards quickly, granting Visage a massive amount of gold.
* Visage can use 
Stone Form of the Familiars to cancel Shackles. 
Aghanim's Shard upgraded Stone Form also allows Visage to use Stone Form himself to cancel Shackles while restoring his health.
* 
Grave Chill can make Shadow Shaman's bad movement speed and attack speed even worse.
* Visage is also a natural 
Bloodthorn wielder, which allows him to silence Shadow Shaman and make him more vulnerable to damage.
Additional:
* Due to their high attack speed, Visage's Summon Familiars will destroy Mass Serpent Ward quickly, granting Visage massive amount of gold.
Tiny
* Tiny can deal with 
Visage's 
Gravekeeper's Cloak quickly, as Avalanche deals damage in enough instances to completely remove all 4 layers of the passive. With Visage's lower than average Armor, a well positioned stun can allow Tiny to kill Visage easily.
Additional:
* Tiny's Avalanche removes a significant number of layers from Gravekeeper's Cloak. When combined with Toss burns through all of Gravekeeper's Cloak while doing triple times Toss damage to Visage in midair.
* Tiny's already high damage coupled with 
Tree Grab's attack modifier will make short work of Visage's Familiars.
Tiny
* 
Feast will deal a enormous amount of damage because of Tiny's huge health pool.
* 
Rage protects Lifestealer from Tiny's magical burst damage.
Tiny
* 
Blade Fury protects Juggernaut from all of Tiny's magic burst damage.
Shadow Shaman
* Riki is known for being a successful support killer, something Shadow Shaman is very vulnerable to.
* 
Smoke Screen is particularly devastating to Shadow Shaman. With neither his various disables nor a solid health pool Shadow Shaman is usually dead. This forces Shadow Shaman to buy a 
Force Staff if he finds himself in this scenario and buy 
Sentry Wards if you have the money.
Tiny
* 
Reaper's Scythe will turn Tiny's high health against him.
* 
Heartstopper Aura does substantial damage to Tiny as a result of his high max health.
* 
Ghost Shroud protects Necrophos from Tiny's physical damage with Tree Grab and Tree Volley.
Shadow Shaman
* 
Ether Shock is a great farming ability as a handy short-cooldown nuke.
* 
Hex and 
Shackles gives Rubick extra lockdown potential in ganks and teamfights.
* Mass Serpent Ward, should Rubick steal, serves as a powerful source for teamfighting, pushing, and acquring Roshan.
* 
Arcane Supremacy allows Rubick to cast Hex and Shackles at a further distance, which keeps Rubick at a safer position compared to Shadow Shaman.
* Rubick can interrupt Shackles by casting 
Telekinesis.
Additional:
* All abilities from Shadow Shaman can very vulnearble steal from 
Spell Steal.
* Rubick can interrupt Shackles by casting Telekinesis.
Shadow Shaman
* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Tiny
* Tiny's nonexistent armor in the early game makes him very vulnerable to 
Quill Spray's large amounts of physical damage.
* 
Bristleback decreases Tiny's high burst damage against Bristleback.
* 
Viscous Nasal Goo can slow Tiny to a crawl and allows Bristleback to easily kite him with his high movement speed and Quill Spray's long range, as Tiny has no ability to escape.
Shadow Shaman
* Mirana can disturb Shadow Shaman's channeling even if he is under the effect of invisibility thanks to 
Sacred Arrow.
* Mirana armed with an 
Aghanim's Scepter is known to be able to quickly burst down heroes - especially supports. Together with 
Ethereal Blade the bullying towards Shadow Shaman can continue for the whole match.
Shadow Shaman
* 
Waveform allows Morphling to escape from Mass Serpent Ward
* Morphling can interrupt Shadow Shaman while he is shackling an ally with 
Adaptive Strike (Strength).
* With Ethereal Blade Morphling can quickly burst him down before he even has a chance to react.
Tiny
* Primal Roar and the slow from Boars make kiting Tiny very easy.
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like 
Phantom Assassin and 
Tinker are very effective because of Tiny's low attack speed. Additionally, 
Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Shadow Shaman
* By simply using Aphotic Shield, Abaddon can easily save his allies from heroes that apply long disables, such as 
Lion or Shadow Shaman.
Shadow Shaman
* 
Omniknight can dispel Hex or Shackles with 
Heavenly Grace. He can also heal teammates who you disabled. The same goes for 
Abaddon's 
Aphotic Shield.
Shadow Shaman
* 
Arc Warden with his Magnetic Field will protect allies from Mass Serpent Ward.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (
Clinkz, 
Templar Assassin, 
Ursa, 
Wraith King etc).
Tiny
* 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.
Shadow Shaman
* Pudge, Legion Commander and 
Axe will make the match a living hell for Shadow Shaman, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt Shadow Shaman's channeling, Legion being especially problematic, as she can use 
Press the Attack on an ally who is hexed as well.
Shadow Shaman
* 
Nyx Assassin, Bounty Hunter and 
Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with 
Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Shadow Shaman
* Heroes with summons and illusions can find themselves easily bested by Lina, like 
Broodmother, 
Nature's Prophet, 
Chen, 
Terrorblade, 
Naga Siren, Visage, Wraith King, 
Lycan, 
Phantom Lancer, Shadow Shaman.
Tiny
* He can quickly take out heroes with low armor (Tiny) with his great physical damage.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
Tiny
* Heroes that are able to slow Tiny's attack speed, like 
Tusk and 
Phoenix, will greatly limit his Physical damage output.
Shadow Shaman
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
Shadow Shaman
* Heroes that have a channeled ability that can be interrupted by Meat Hook: Shadow Shaman, 
Witch Doctor, Enigma, Bane.
Tiny
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Tiny
* Avalanche and Toss will never be enough damage to take out Sven in a clean way.
* Tiny is very slow with low armour growth and does not buy items to sustain Sven's damage output.
Shadow Shaman
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or 
Magnus.
Shadow Shaman
* With all 5 Meepos available, all of Shaman's wards will be disposed of very quickly.
* All of Shaman's disables are based around single target control, and he can at most only disable two Meepos, allowing the rest to easily lay waste to him, be it during the channel duration of Shackles or by using 
Earthbind.
Tiny
* 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.
Tiny
* Tiny has low movement speed and attack speed, making him vulnerable to Viper's slows.
* 
Corrosive Skin provides magic resistance to lower Tiny's magic burst damage.
Shadow Shaman
* Viper cannot interrupt heroes with powerful channeling abilities: Bane, Enigma, Shadow Shaman, Warlock
Shadow Shaman
* Luna's high magical damage burst from 
Lucent Beam and 
Eclipse can take advantage of Shadow Shaman's low health and strength gain.
* Without 
Black King Bar, Luna's Lucent Beam and 0.25 Eclipse Mini-stun talent for Eclipse can be used to disable Shadow Shaman while he is channeling Shackles.
* Aghanim's Scepter upgraded Eclipse combined with 0.25 Eclipse Mini-stun can repetively stun Shadow Shaman, and can even discourage him from even trying to use Shackles.
* Luna is a natural Black King Bar wielder, and almost none of Shadow Shaman's spells can bypass spell immunity, except for Mass Serpent Ward.
* Bear in mind, however, that if Shadow Shaman gets a jump on Luna first, he will be able to use Hex to disable Luna and burst her down before she can use Black King Bar, Lucent Beam or Eclipse. In addition, 
Moon Glaives cannot bounce on Mass Serpent Wards at all.
Additional:
* Luna's high magical damage burst from Lucent Beam and Eclipse can take advantage of Shadow Shaman's low health and strength gain.

Shadow Shaman
* A couple of nukers and disablers on the same lane can finish a squishy Luna efficiently despite a teammate's assistance: Sven + Shadow Shaman.
Tiny
* Invoker is a big problem for Tiny the whole game because of its multiple disables. For example, the 
Cold Snap ability can catch an attack from Tiny's hand by surprise, because it becomes slower with the pumping of 
Grow. has a giant deceleration, creating a condition for the kite, which Tiny is very afraid of. In addition, Invoker has a 
Deafening Blast that disables Tiny's main weapon - strong blows from the hand
Additional:
* Invoker is a big problem for Tiny the whole game because of its multiple disables. For example, such as 
Tornado + 
E.M.P. create unrealistic conditions for Tiny with mana, which is very necessary for Tiny at least for some attacks in a fight. The Cold Snap ability can catch an attack from Tiny's hand by surprise, because it becomes slower with the pumping of Grow. has a giant deceleration, creating a condition for the kite, which Tiny is very afraid of. In addition, Invoker has a Deafening Blast that disables Tiny's main weapon - strong blows from the hand
Shadow Shaman
* Heroes with long lockdowns: Shadow Shaman, Legion Commander.
Tiny
* Squishy heroes, usually supports, like Lion, 
Ancient Apparition, 
Keeper of the Light etc can die quickly to Tiny's magic burst.
Shadow Shaman
* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: 
Invoker, Silencer, Nyx Assassin, 
Skywrath Mage, Shadow Shaman, Lion and etc.
Shadow Shaman
* Shackles prevents Chen from acting, and damages him while healing Shadow Shaman, also allowing Shadow Shaman's allies to kill him faster. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Chen while he is disabled. And to make things worse, Chen has no way to cancel Shackles on his own, and must rely on outside from {U:Centaur Conqueror} or {U:Mud Golem} under his control.
* Ether Shock and Mass Serpent Ward can often not only kill Chen's allies before he can save them with 
Hand of God, but they can also be used to destroy Chen's creeps easily thanks to their high damage and area-of-effect.
* Hex will prevent Chen from any attempt to save himself or his allies with Hand of God.

* Hex will prevent Chen from any attempt to save himself or his allies with Hand of God.
Shadow Shaman
* Shackles and Hex can both be used on Muerta while in 
Pierce the Veil, potentially wasting it until she gets Black King Bar.
* Ether Shock and Shackles can deal high damage to Muerta while she is affected by Pierce the Veil.
* However, Mass Serpent Ward cannot hurt Muerta while Pierce the Veil is active.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Tiny
* Heroes that have disposable area-targeted spells can force her to undo her Meld: 
Leshrac, 
Puck, Tiny, 
Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Shadow Shaman
* Shackles and Mass Serpent Ward instantly destroy 
Refraction
Tiny
* Avalanche and Toss combo makes short work of 
Mirror Image's illusions.
* Tiny's cleave with Tree Grab and area of effect damage with Tree Volley will easily wipe out illusions.
Shadow Shaman
* Shadow Shaman's Mass Serpent Ward together with Ether Shock can easily kill lots of Treants if played defensively.
* Hex and Shackles can disrupt Nature's Prophet's escape attempts with Teleportation.
Additional:
* Mass Serpent Ward can kill lots of treants if played defensively.
* Mass Serpent Ward, Hex, and Shackles can catch and kill a Nature's Prophet trying to use Teleportation.
Shadow Shaman
* Mass Serpent Ward rips apart Huskar quickly due to his poor armor.
* As soon as Huskar jumps in, he will be vulnerable to Shadow Shaman's disables if he does not have Black King Bar.
Shadow Shaman
* Hex greatly reduces Timbersaw's mobility.
* The stun and damage over time from Shackles mitigates Reactive Armor's HP and armor regen.
Shadow Shaman
* Shadow Shaman has many disables to lock down Queen of Pain, preventing her from Blinking away, even through 
Linken's Sphere or her spell block talent.
* Mass Serpent Ward can tear through Queen of Pain's low health pool once she's locked down by Hex & Shackles.
Shadow Shaman
* Shadow Shaman's long disables are effective at kiting and wasting the duration of Battle Trance.
* Mass Serpent Ward are especially effective against Troll Warlord during Battle Trance, as trapping him inside them during the duration is effectively another hard disable, as Troll cannot attack the wards or use Phase Boots to escape.
Shadow Shaman
* Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Shaman has used all his crowd control before entering a fight.
* Brewmaster also has no defense against Shadow Shaman lockdowns.
Shadow Shaman
* Shadow Shaman's many disables can lock down Weaver. Even with Linken's Sphere, Weaver might not be able to escape should Shadow Shaman uses Shackles quickly enough following Hex.
* Mass Serpent Wards can make short work of Weaver once he is locked down.
Shadow Shaman
* Heroes with break can disable Untouchable for a while: Doom and 
Shadow Demon (via Aghanim's Scepter), 
Viper, Shadow Shaman with Hex Breaks talent.
Shadow Shaman
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: Sven, Omniknight, Enigma, 
Luna, Naga Siren, 
Mars, Jakiro, 
Venomancer, 
Elder Titan, 
Faceless Void, 
Rubick, Keeper of the Light, 
Pugna, Invoker, 
Spectre, Alchemist, 
Treant Protector, 
Lina, 
Oracle, 
Zeus, Shadow Shaman, Phoenix, 
Razor, 
Huskar, 
Batrider, 
Kunkka, 
Tidehunter, Wraith King, 
Sand King, 
Medusa, Dawnbreaker.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Shadow Shaman
* In general, squishy heroes that rely on escape often struggle against the amount of disables Shadow Shaman can bring. 
Queen of Pain, 
Anti-Mage and 
Storm Spirit are among these.
Shadow Shaman
* Heroes with channeling spells because Shadow Fiend has nothing to cancel channeling outside of Requiem of Souls: Bane, Enigma, Pudge, Shadow Shaman, Dawnbreaker, Warlock, Crystal Maiden.
Shadow Shaman
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Shadow Shaman
* Heroes with both illusions and summons, for Io has nothing to deal with multiple enemies at once outside from Spirits's weak area-of-effect: Beastmaster, Broodmother, 
Chaos Knight, Lycan, Naga Siren, Nature's Prophet, Phantom Lancer, Shadow Shaman, Terrorblade, Visage, Warlock, Wraith King.
Tiny
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, 
Ogre Magi.
Shadow Shaman
* Heroes that can keep Marci for a long time in one place so she can't pursue her targets, like Bane, Lion, Shadow Shaman, Invoker, 
Disruptor and Kunkka.
Additional:
* Shadow Shaman can provide an excellent counter-initiation against her 
Rebound. His abilities can shut down any of her tower dive attempts in the laning phase.
* Shackles keeps Marci stunned for an extended time, wasting her ultimate. A combo with Mass Serpent Ward only makes things worse for her, as her armor is low.
Shadow Shaman
* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, 
Dazzle from Aghanim's Shard with upgraded 
Poison Touch.
Shadow Shaman
* Heroes who can clear the waves of Enigma's Eidolons: Lina, Luna, Dawnbreaker, Jakiro, Shadow Shaman, Death Prophet, Keeper of the Light, Invoker, Leshrac, Puck.
Tiny
* Heroes with high base damage (
Morphling, Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and 
Diffusal Blade users (
Juggernaut or 
Riki) will suffer from Reflection's illusions.
Shadow Shaman
* All of Shadow Shaman's abilities totally ruin Terrorblade: Ether Shock destroys his illusions, Hex prevents him from using 
Sunder or 
Manta Style in bad situations, Shackles not only that prevent him from using Sunder, but he has no way to cancel it and Mass Serpent Ward can help Shadow Shaman push faster than Terrorblade even in 
Metamorphosis.
Additional:
* Ether Shock, Mass Serpent Wards summoned from both, Mass Serpent Ward and Aghanim's Shard upgraded Shackles can do great damage to both, Terrorblade and his illusions.
* Hex prevents Terrorblade from using Sunder or Manta Style in bad situations. Hex can also destroy one of his illusions.
* Shackles can damage Terrorblade and prevent him from using his abilities and items, whether to fight, survive, or dispel it in any way while also healing Shadow Shaman in process. In addition, Terrorblade has no solutions to cancel it. Aghanim's Shard upgraded Shackles can also summon four more Mass Serpent Wards to attack Terrorblade while he is disabled.
Shadow Shaman
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned Drow Ranger and Sniper) and supports (like Dazzle and Shadow Shaman).
Shadow Shaman
* Hex can be used immediately to destroy Spectre's illusion when she 
Haunts.
* Shadow Shaman can use Shackles to lock down Spectre for his team.
* Shadow Shaman's Mass Serpent Ward and Ether Shock help him push lanes and end the game early before Spectre can come online and take over the late game.
Shadow Shaman
* Nyx Assassin, Bounty Hunter and Slark can all sneak up and kill Shadow Shaman, Nyx being particularly deadly. Shadow Shaman must watch out for Slark carefully, as he can break either (but not both unless he makes a mistake) of Shadow Shaman's disables, with Dark Pact and leap out of a serpent ward ring. These heroes, however, rely heavily on escape and are themselves not very durable and none of them can survive a full lockdown with Mass Serpent Ward. Having Sentry Wards can turn Shadow Shaman from prey to predator.
Tiny
* Toss and Avalanche deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
* Tiny has 0 agility, which means Slark's 
Essence Shift permanent agility steal does not do much against him.
Shadow Shaman
* Heroes that are squishy by nature are an easy target for Spirit Breaker: Sniper, Drow Ranger, Shadow Shaman
Shadow Shaman
* Can easily interrupt and disable Spirit Breaker with hex if being charged.
Shadow Shaman
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: Shadow Shaman, Visage, Dazzle, Rubick, 
Lich.
Tiny
* Tiny can quickly clear Spiderlings with his active abilities and cleave.
Shadow Shaman
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.
Tiny
* Tiny can be a serious problem for the distance between Lone Druid and his 
Summon Spirit Bear with his Toss ability, since he will throw one away from the other, giving his team the opportunity to deal with either the Summon Spirit Bear or Lone Druid himself
* Lone Druid will not always be in his 
True Form, since she has her own recharge, which is why Tiny can find him with a 
Shadow Blade or 
Blink Dagger and kill him in a second with a combination of Avalanche and Toss, due to the fact that Lone Druid has a very small health reserve without True Form
Additional:

Tiny
* 
Mana Drain has an fair long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as Tiny or 
Spirit Breaker.
Additional:
* Lion can continuously Mana Drain Tiny in the early game, depleting his small mana pool for his abilities.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Shadow Shaman
* As a caster, Anti-Mage's 
Mana Break and 
Mana Void are highly effective against him.
Shadow Shaman
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, 
Grimstroke, Witch Doctor, Riki, Faceless Void, Skywrath Mage, Puck.
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like Phantom Assassin and Tinker are very effective because of Tiny's low attack speed. Additionally, Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Shadow Shaman
* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.
Shadow Shaman
* Pudge, Legion Commander and Axe will make the match a living hell for Shadow Shaman, since they are known for surprise attacks from the fog and quickly killing low HP heroes. They can also interrupt Shadow Shaman's channeling, Legion being especially problematic, as she can use Press the Attack on an ally who is hexed as well.
Shadow Shaman
* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (
Clinkz, 
Templar Assassin, 
Ursa, 
Wraith King etc).
Shadow Shaman
*
Reincarnation allows Wraith King to survive Shadow Shaman's initial chain of disables and Serpent Ward attacks.
Wraithfire Blast is ideal for interrupting Shackles.
* Short cooldown of
