* 
Life Break and 
Burning Spear usually kills Gyrocopter before he can do much damage to Huskar.
* 
Inner Fire applies a disarm on all enemies, which can be a hindrance to Gyrocopter.
Undying
* 
Huskar's huge damage output and attack speed can get rid of Undying and Tombstone quickly.
Gyrocopter

* 
Reactive Armor makes Timbersaw very effective against heroes that control a lot of units, such as 
Broodmother, 
Lycan and 
Undying.
Gyrocopter
* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, 
Gyrocopter's

Gyrocopter
* 
Blade Fury and 
Omnislash allows Juggernaut to avoid Gyrocopter's area attacks entirely.
Undying

Global Silence are able to silence Undying for up to 6 seconds, preventing Undying from gaining strength and healing his ally or himself.
Undying

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.

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
* 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.

* 
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.

* All abilities from Undying easy to steal to Rubick with 
Spell Steal.
Undying
* Sniper can easily destroy Tombstone from long range.

Gyrocopter
* Heroes with weaker mobility will struggle to keep up with Night Stalker: Gyrocopter, 
Ursa, 
Drow Ranger
Gyrocopter

Anti-Mage, 
Clinkz, Drow Ranger,

Meepo, 
Mirana, 
Monkey King, 
Morphling,

Lina, 
Lion, Zeus
Gyrocopter
* Any hero with a low HP pool is easy for Tinker to nuke down: 
Crystal Maiden, 
Enchantress, Gyrocopter, Lion, Riki, 
Techies, Terrorblade, 
Necrophos, 
Invoker.
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.
Undying
* Invoker's multiple spells can lock down Undying and disable him from doing much.
Gyrocopter
* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: 
Storm Spirit, Morphling, 
Ember Spirit

Spirit Breaker, Gyrocopter, 
Leshrac
Undying
* Mirana can destroy Tombstone, and evade zombies using Leap and Moonlight Shadow's invisibility.
Gyrocopter
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: 
Axe, 
Dragon Knight, 
Sven.
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
* 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
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.
Gyrocopter
* 
Flak Cannon and Call Down can easily clear Naga Siren's illusions.
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.
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
* 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
* 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.

Relocate.
* Flak Cannon allows Gyrocopter to attack both, Io and his 
Tethered target, especially when upgraded with 
Aghanim's Scepter.

* Rocket Barrage and Call Down allow Gyrocopter to deal serious damage to both Io and his Tethered target.
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.
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.

Queen of Pain, 
Shadow Shaman (
Shackles), 
Jakiro,

* Multiple attackers thanks to summoned units or clones: Meepo, 
Witch Doctor, Lycan, 
Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, 
Chaos Knight, 
Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom
Undying
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.

Luna, Lina, 
Tusk, Broodmother, Shadow Fiend, Ember Spirit, Gyrocopter, 
Vengeful Spirit, 
Arc Warden, 
Medusa, Shadow Shaman.
Gyrocopter
* Heroes that relies on armor or other type of physical damage negation are easy for Gyrocopter to take down during the early game with his magical damage: Axe, Dragon Knight, Sven.

Gyrocopter
* Flak Cannon destroys Phantom Lancer's illusions very quickly.
Additional:
* Flak Cannon and Call Down destroy Phantom Lancer's illusions very quickly.
Gyrocopter
* Abilities that deal low damage with high amounts of instances are irrelevant against Pudge during Flesh Heap's active: Gyrocopter's Rocket Barrage and

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.
Gyrocopter
* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like Gyrocopter, 
Kunkka, Magnus and Medusa.
Gyrocopter
*
Rage ignores all of Gyrocopter's magical attacks.
Feast helps Lifestealer out-damage Gyrocopter at close range.
*
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.
