Undying
* 
Death Prophet is able to 
Silence Undying up to 6 seconds. Besides, due to Undying's high strength during a team fight, 
Spirit Siphon is a powerful ability against Undying thanks to the percentage health drain.
Void Spirit
* Spirit Siphon and 
Exorcism can damage through his 
Resonant Pulse shields.
* Silence can prevent Void Spirit escape or contributing much in fights.
Undying
* 
Meepo can quickly destroy Tombstone thanks to 
Divided We Stand.
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.
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
Undying
* Due to Fervor and Battle Trance, Troll Warlord has a significant attack speed, enabling him to crush 
Tombstone quickly.
* Undying usually stays at the front line with no disables, making him an easy target for Troll Warlord.
Undying
* Luna's 
Moon Glaives and 
Lunar Blessing can help her destroy Tombstone easily, and this becomes more effective if Luna is equipped with 
Manta Style.
* Spell Immunity of Zombies from Tombstone is a total disadvantage against Luna because 
Eclipse will strike only Undying, which can turn Undying's own ability against him.
* Though Undying often builds 
Blade Mail which can turn Luna's burst damage against her, Luna often builds 
Black King Bar which will allow her to attack Undying freely because Blade Mail cannot pierce spell immunity.

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.
Undying
* Necrophos is a dangerous opponent to go against with. Regardless of how much strength Undying has gained from Decay, Necrophos can finish off Undying with 
Reaper's Scythe once Undying's HP falls below a certain threshold.
* 
Heartstopper Aura will do more damage to Undying if he gained strength from Decay, as it does damage based on a hero's maximum health.
Undying
* Zombies summoned from Tombstone will amplify the damage of 
Echo Slam due to them increasing the echo damage.
Undying
* 
Arcane Curse can effectively discourage Undying from casting his spammable abilities in a team fight, as Undying will have to suffer more damage and the slow due to the penalty duration of Arcane Curse.
* 
Last Word and 
Global Silence are able to silence Undying for up to 6 seconds, preventing Undying from gaining strength and healing his ally or himself.
Undying
* Geminate Attack works on Tombstone, allowing Weaver to kill it quickly.
* Zombies attacking Weaver disappear once he goes invisible with Shukuchi.
* Undying has no way to catch a mobile Weaver.
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.
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.
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.
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.
Undying
* Chemical Rage will take down Tombstone in no time.
Additional:
* With 
Greevil's Greed, Alchemist can farm Tombstone zombies and gain a significant gold advantage.
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

Undying
* Sniper can easily destroy Tombstone from long range.
Void Spirit
* 
Refraction negates all of Void Spirit's burst damage.
* 
Meld quickly burns through Resonant Pulse.
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.
Undying
* Tidehunter takes close to no damage from Undying's zombies once he maxes out his 
Kraken Shell, especially if he gets the level 20 Kraken Shell upgrading talent. This might allow him to blink away to safety.
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.
Undying
* All abilities from Undying easy to steal to Rubick with 
Spell Steal.
Additional:
* Tombstone can be stolen to counter-initiate the enemy team in skirmishes.
* Tombstone provides vision over the enemy around, use this to Rubick's advantage for more spells.
* Since 
Undying is melee and has low attack speed, the tombstone can be hard to taken down by Undying himself.
* 
Flesh Golem provides Rubick with increased Health pool and a powerful attack modifier.
* 
Rubick can apply the Flesh Golem debuff much more easily as a ranged hero.
* 
Decay is a decent damaging ability, making Rubick somewhat tankier in teamfights.
* 
Soul Rip can be used for extra heal or burst damage.
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
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: 
Puck, Void Spirit, 
Mars.
Undying
* 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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: 
Sven, Tiny, 
Wraith King, 
Ogre Magi.
Void Spirit
* Heroes that can purge his slow and disables are very difficult to go on and their team: 
Abaddon, 
Oracle.
Void Spirit
* Heroes that can purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Undying
* 
Huskar's huge damage output and attack speed can get rid of Undying and Tombstone quickly.
Undying
* 
Chaos Knight's multiple illusions from 
Phantasm can destroy Undying, as Soul Rip can't offset the damage from the high amount of damage from his illusions.
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
* 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.
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.
Undying
* 
Mirana can destroy Tombstone, and evade zombies using Leap and Moonlight Shadow's invisibility.
Undying
* In general, melee 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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
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.
Undying
* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, 
Gyrocopter's 
Homing Missile, and 
Zeus's 
Nimbus.
Undying
* 
Reactive Armor makes Timbersaw very effective against heroes that control a lot of units, such as 
Broodmother, 
Lycan and Undying.
Undying
* Tombstone's zombies rarely inhibit Anti-Mage, as he can either Blink away or onto the Tombstone and destroy it.
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.
Undying
* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.
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
* 
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.
Undying
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.
Undying
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the Tombstone zombies.
* The potency of Soul Rip can be increased from nearby illusions from Haunt.
* Decay will shut down Spectre during the laning phase by effectively cutting down her initial health pool.
Additional:
* Spectre must chase for kills and relies on movement speed for mobility in fights, and has no way to counter the Tombstone zombies.
* The potency of Soul Rip can be increased from nearby illusions, so Undying can use 
Haunt against Spectre.
* Early game Decay will make Spectre easy to shut down in lane.
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.
Undying
* Decay, Soul Rip and Flesh Golem all deal magical damage which ignores Bulwark.
* Decay reduces Mars' natural strength and therefore his health pool, which is what he relies on to trade effectively in lane.
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
* 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 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.
Undying
* Undying's Decay is a dangerous ability against Bristleback, as it makes him more vulnerable and reduces his tankiness.
* Undying's Tombstone together with Flesh Golem can slow Bristleback down significantly.
Undying
* Due to Spirit Breaker's low attack speed, Tombstone is problematic for Spirit Breaker as the zombies summoned from Tombstone apply a stacking movement speed slow, which can significantly reduce Greater Bash's damage.
* Soul Rip and Decay allows Undying and his allies to survive and recover from any incoming ganks by Spirit Breaker.
Undying
* Undying's Tombstone will cheerfully chew through treants, incidentally netting you some extra income during fights.
* The above interaction tends to ensure that skirmishes are heavily populated with units, thereby buffing Soul Rip
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.
Undying
* Winter Wyvern cannot handle the Zombies created by Undying's Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well.
Additional:
* Winter Wyvern cannot handle the Zombies created by Tombstone very well. In most situations, Zombies will have more movement speed than her.
* Undying can gain one or two easy Decay stacks on an ally in Cold Embrace. The ally will still take the damage as well, since it is magical.
Void Spirit
* Void Spirit's AoE damage make short work of Broodmother's spiderlings
* Even in she is within the range of her spiderwebs from 
Spin Web Broodmother cannot escape Void Spirit's mobility.
Additional:
* Void Spirit's AoE damage make short work of Broodmother's spiderlings
* Broodmother cannot escape Void Spirit's mobility, even in her webs.
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.
Undying
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are 
Crystal Maiden and 
Witch Doctor.
Undying
* Anti-Tank heroes like: 
Razor, 
Necrophos, Undying.
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
* 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
* 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
* Heroes that can summon units will have their summons destroyed very quickly if badly micro-managed, like Chen, Lycan, and 
Phantom Lancer.
Undying
* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are Crystal Maiden and Witch Doctor.
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.
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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Undying
* Undying can use Decay not only to reduce Sven's maximum health, but also to reduce the damage he can deal with his ultimate.
* Zombies spawned by Tombstone together with Flesh Golem slow Sven down significantly. Landing Sven's powerful but somewhat slow right-click on Tombstone would be a waste.
Undying
* 
Invoker's multiple spells can lock down Undying and disable him from doing much.
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.
Void Spirit
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Undying
* Undying saps strength from heroes with Decay, and Ogre Magi's high strength gain will allow Undying to steal more and more strength, becoming stronger with each use.
* Due to the Strength steal from Decay, Undying is normally very tanky, and has high health, making it harder for Ogre Magi to kill him.
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.
Undying
* Decay can be good against Centaur Warrunner, as reducing the health of Centaur can make 
Double Edge risky.
* His zombies do not proc 
Retaliate, as it only procs for regular attacks.
Undying
* 
Terrorblade can destroy Tombstone with his 
Conjure Image and 
Metamorphosis.
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.
Undying
* Flak Cannon rips through Tombstone's zombies.
Additional:
* 
Flak Cannon enables Gyrocopter to clear the zombies easily.
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.
Undying
* Phantom Lancer's many illusions will easily destroy Tombstone, provided he has sufficient farm.
* He also has no ways of dealing with the illusions, since Decay doesn't steal strength from illusions.
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.
Undying
* Lifestealer is able to endure Undying, especially in the laning phase, where Undying is strongest. Feast can offset
Decay's strength steal for its percentage lifesteal. Rage delays Undying from stealing strength and can help Lifestealer destroy Undying's 
Tombstone uninterrupted. As well, none of Undying's abilities pierce magic immunity.
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.
