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.
Void Spirit
* One hit with 
Jinada should be sufficient in removing Void Spirit's shield most of the time.
* 
Track negates much of Void Spirit's escape abilities by revealing his position and prevents him from rotating effectively.
Shadow Shaman
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as 
Silencer, 
Drow Ranger and 
Death Prophet.
Void Spirit
* 
Spirit Siphon and 
Exorcism can damage through his 
Resonant Pulse shields.
* 
Silence can prevent Void Spirit escape or contributing much in fights.
Shadow Shaman
* Dragon Knight can simply tank and destroy all Shadow Shaman's Serpent Wards.
Void Spirit
* Heroes who can match Void Spirit's mobility (like the aforementioned 
Ember Spirit or 
Queen of Pain) or tank his spells (
Dragon Knight or 
Centaur Warrunner) are very problematic for him.
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.
Void Spirit
* Meepo's Earthbind can easily lockdown Void Spirit.
* Meepo and his clones can easily burst Void Spirit's Resonant Pulse.
Void Spirit
* 
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.
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.
Void Spirit
* Heroes that can purge his slow and disables are very difficult to go on and their team: 
Abaddon, 
Oracle.
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.
Void Spirit
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like 
Ursa, 
Lifestealer, or Axe.
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.
Void Spirit
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: 
Puck, Void Spirit, 
Mars.
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.
Void Spirit
* Ember Spirit has much higher mobility in 
Fire Remnant than Void Spirit.
* Ember's 
Flame Guard is effective against Void Spirit's spells, as most of them deal magical damage.
* The root from 
Searing Chains prevents Void Spirit from using Dissimilate or Astral Step.
Void Spirit
* 
Rupture will fully damage Void Spirit during his ultimate, removing his main escape mechanic during fights and his way to disrupt them heavily.
* 
Blood Rite will force Void Spirit to use Dissimilate or Astral Step or be silenced. In the latter's case, it can be dangerous when combined with Rupture.
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.
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.
Void Spirit
* The brutal physical damage of 
Slithereen Crush and 
Bash of the Deep can quickly remove Void Spirit's shield and stun him for a while.
* 
Corrosive Haze provides vision of Void Spirit while he is running away and 
Guardian Sprint allows Slardar to quickly close the gap
Void Spirit
* Lion's instant cast point shuts down his initiation and buys time for his allies to catch up.
* Void Spirit has to be cautious when fighting, as he has no protection against 
Finger of Death. If caught out in a stun, the high magic damage could end him quickly.
Shadow Shaman
* Sniper can easily destroy Mass Serpent Wards from long range.
Void Spirit
* Void Spirit can easily be bursted down by Puck's high magic damage spells in early game.
* Wanning Rift and Dream Coil prevent him from using two of his important mobility abilities: Dissimilate and Astral Step.
Additional:
* 
Dream Coil prevents the usage of Void Spirit's escape abilities and limits his damage output in fights almost entirely.
* Killing Puck in the late game becomes difficult when they obtain a 
Eul's Scepter of Divinity, 
Blink Dagger, and 
Phase Shift.
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.
Void Spirit
* 
Doom is effective against every hero, and Void Spirit is no exception. Being unable to cast spells or items during fights for 16 seconds nullifies his impact entirely.
* Doom has a very versatile build and can consume creeps which has abilities that can stun or provide additional magic resistance.
* Doom's high strength gain and versatility in items can be effective against Void Spirit's magical damage.
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.
Void Spirit
* Heroes that can purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Shadow Shaman
* 
Arc Warden with his Magnetic Field will protect allies from Mass Serpent Ward.
Void Spirit
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like Ursa, Lifestealer, or Axe.
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.
Void Spirit
* Special mention to Legion Commander, as she can lock down Void Spirit for a long amount of time without worrying too much about being killed by him during the 
Duel.
Shadow Shaman
* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion
Void Spirit
* Heroes with burst damage of their own won't be afraid to go toe to toe with Void Spirit, like Ursa, Lifestealer, or Axe.
Void Spirit
* Heroes who can match Void Spirit's mobility (like the aforementioned Ember Spirit or Queen of Pain) or tank his spells (Dragon Knight or Centaur Warrunner) are very problematic for him.
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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: 
Sven, 
Tiny, Wraith King, 
Ogre Magi.
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
* Heroes with channeling spells are very easy targets for Jakiro's abilities: Crystal Maiden, 
Dawnbreaker, 
Enigma, Pudge, 
Shadow Fiend, Shadow Shaman, 
Warlock.
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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Shadow Shaman
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane, 
Beastmaster, 
Bloodseeker, 
Clockwerk, 
Doom, Shadow Shaman.
Void Spirit
* 
Fiend's Grip and 
Nightmare are very useful to lock down Void Spirit.
* 
Brain Sap can be difficult for Void Spirit to deal with in the laning stage.
Shadow Shaman
* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, 
Dazzle from Aghanim's Shard with upgraded 
Poison Touch.
Void Spirit
* 
Poison Attack makes it hard for Void Spirit to lane against him.
* 
Corrosive Skin reduces the magical damage from Void Spirit's spells.
Shadow Shaman
* Viper cannot interrupt heroes with powerful channeling abilities: Bane, Enigma, Shadow Shaman, Warlock
Void Spirit
* Wins on the central line, thanks to its strong nukes 
Shadowraze, because of which Void Spirit cannot approach the creeps to farm gold and overtake Shadow Fiend by level
Additional:
* Wins on the central line, thanks to its strong nukes Shadowraze, because of which Void Spirit cannot approach the creeps to farm gold and overtake Shadow Fiend by level
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
* 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.

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.
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.
Void Spirit
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: 
Phantom Assassin, Nyx Assassin, 
Mirana, Bounty Hunter, 
Templar Assassin, 
Riki, 
Spirit Breaker, 
Anti-Mage, 
Tusk, Ursa, Nature's Prophet, Enigma, Void Spirit, 
Magnus etc.
Void Spirit
* Void Spirit's AoE damage can make short work of Broodmother's spiderlings
* Even if she is within the range of her spiderwebs from Spin Web Broodmother cannot escape Void Spirit's mobility.
* However, Spinner's Snare from Aghanim's Scepter can be very hazardous for Void Spirit, as it allows Broodmother to create invisible lines on her webs from Spin Web that will root Void Spirit, deal damage over time to him and reveal him if he unwittingly steps on them, disrupting Void Spirit's ganking or escaping attempts with Dissimilate and Astral Step while also alerting Broodmother on his attempts to ambush her and her allies.

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.
Additional:

* Hex will prevent Chen from any attempt to save himself or his allies with Hand of God.
Void Spirit
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, 
Clinkz, 
Sniper, Slark, Phantom Assassin, Void Spirit, 
Storm Spirit, Ember Spirit, 
Earth Spirit, Spirit Breaker.
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.
Void Spirit
* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, 
Batrider, 
Earthshaker, 
Elder Titan, 
Faceless Void, 
Invoker, Legion Commander, Mars, 
Primal Beast, Riki, Shadow Shaman, Silencer, 
Vengeful Spirit, Void Spirit.
Additional:
* Void Spirit's high mobility becomes a nuisance to Terrorblade.
* Void Spirit's arsenal of magic damage is effective against Terrorblade's low strength.
* Terrorblade has no disables to prevent Void Spirit from escaping.
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.
Void Spirit
* Heroes with abilities that can close the gap can easily kill Muerta: Storm Spirit, Earth Spirit, Ember Spirit, Void Spirit, Lycan, 
Chaos Knight, Tusk.
Shadow Shaman
* Heroes with long lockdowns: Shadow Shaman, Legion Commander.
Void Spirit
* A good choice against Invoker, as it has some advantage with the help of abilities.
* With the Dissimilate, Voidspirit can evade Invoker's skills, going to another world where he does not receive damage. The same ability to run away or attack quickly.
* Astral Step moves quickly from point to point, which also reduces the Invoker's probability that he will hit him with skills and cause at least some damage.
Additional:
* A good choice against Invoker, as it has some advantage with the help of abilities.
* With the Dissimilate, Voidspirit can evade Invoker's skills, like 
Chaos Meteor or 
E.M.P., going to another world where he does not receive damage. The same ability to run away or attack quickly.
* Astral Step moves quickly from point to point, which also reduces the Invoker's probability that he will hit him with skills and cause at least some damage.
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.
Void Spirit
* Dissimilate and Astral Step allow Void Spirit to quickly escape from Cold Feet.
* Void Spirit deals both magical and physical damage, which makes Ancient Apparition an easy target to ambush.
* If Void Spirit purchases Aghanim's Scepter, the silence provided by Resonant Pulse can disrupt Ancient Apparition during fights, as he is entirely reliant upon spells to contribute.
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.
Void Spirit
* Heroes who take a long time to become strong are in for a rough mid game, such as 
Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
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.
Void Spirit
* Heroes with either magical, physical or pure damage burst: Bane, Ember Spirit, 
Leshrac, Lina, Luna, Nyx Assassin, Phantom Assassin, Skywrath Mage, 
Tinker, Ursa, Void Spirit.
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.
Void Spirit
* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like Ember Spirit, Void Spirit, Storm Spirit, Anti-Mage, Faceless Void, Puck or always build items like Blink Dagger and Force Staff.
Void Spirit
* Astral Step and Dissimilate makes a quick work of Phantom Lancer's illusions.
* Resonant Pulse helps clear illusions and protects Void Spirit from Phantom Lancer's physical damage and with the Aghanim's Scepter upgrade, it prevents Phantom Lancer from casting his abilities.
* Void's Spirit mobility makes it hard for him to chase down with Phantom Rush.
Void Spirit
* Keeping Void Spirit inside 
Wukong's Command is a very tricky task, especially in the early and mid game. In addition, if Monkey King is in a bad position, a well placed Aether Remnant can easily pull him out of the ring.
* Getting stacks of 
Jingu Mastery can be difficult when attacking Void Spirit.
Void Spirit
* Void Spirit can easily dodge Gyrocopter's {Ability ID:Homing Missile|gyrocopter} with the help of Dissimilate.
* Void Spirit can partly dodge 
Call Down via Dissimilate or move out of its range with Astral Step.
* Gyrocopter has no escape abilities, which benefits Void Spirit's high mobility.
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
* 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.
Void Spirit
* Void Spirit is strong against heroes who cannot deal with his rotations due to his mobility. Such heroes include Spectre, 
Gyrocopter, 
Morphling, and Chen.
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'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.
Void Spirit
* Void Spirit deals entirely magical damage in the early game, ignoring her evasion from 
Windrun.
* A Void Spirit with fast reaction time can use Dissimilate or Astral Step to dodge 
Powershot.
Additional:
* Void Spirit deals entirely magical damage in the early game, ignoring her evasion from Windrun.
* A Void Spirit with fast reaction time can use Dissimilate or Astral Step to dodge Powershot.
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.
Void Spirit
* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Void Spirit
* Heroes that can summon units will have their summons destroyed very quickly if badly micro-managed, like Chen, Lycan, and Phantom Lancer.
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.
Void Spirit
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
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
* 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 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
* 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.
Void Spirit
* Heroes who take a long time to become strong are in for a rough mid game, such as Outworld Destroyer, Magnus, Medusa, and Anti-Mage.
Void Spirit

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
* 
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.
Void Spirit
* Void Spirit can greatly pressure Morphling's farm, which is very bad for a hero who needs a large amount of space.
* Waveform does not provide better mobility than Astral Step.
* If Morphling shifted all of his strength to agility, he can be bursted down by Void Spirit before he can react.
* Doing an Ethereal Blade combo on Void Spirit is incredibly difficult, as Dissimilate and Astral Step can allow him to escape or dodge the projectile.
Void Spirit
* 
Refraction negates all of Void Spirit's burst damage.
* 
Meld quickly burns through Resonant Pulse.
Shadow Shaman
* Shackles and Mass Serpent Ward instantly destroy Refraction
Void Spirit
* Queen of Pain can 
Blink to both escape and initiate onto Void Spirit.
* She is also a very common 
Orchid Malevolence carrier, which can prevent Void Spirit from contributing much in fights.
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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Shadow Shaman
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.
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
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate:
Sven, 
Tiny, 
Wraith King, 
Ogre Magi.
