Undying
* 
Tombstone's zombies rarely inhibit Anti-Mage, as he can either Blink away or onto the Tombstone and destroy it.
Tusk
* 
Mana Break is very effective against Tusk, as he has a very low mana pool.
* 
Blink allows Anti-Mage to escape from an incoming Snowball.
* 
Counterspell can reflect the Snowball back onto Tusk.
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.
Tusk
* 
Doppelganger allows Phantom Lancer to dodge an incoming snowball.
* Phantom Lancer usually buys a 
Diffusal Blade, which is very effective against Tusk's low mana pool.
* Phantom Lancer usually buys 
Manta Style which can also dodge an incoming snowball, much like Doppelganger.
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.
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.
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
* Split Shot can destroy Tombstone Zombies and Tombstone itself while still damaging heroes.
Tusk
* 
Boulder Smash can return Tusk after his initiation.
* 
Geomagnetic Grip prevents Tusk from using Snowball to escape.
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
* 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.
Tusk
* 
Static Link drains Tusk's base damage, and it also reduces the critical damage output from 
Walrus PUNCH!.
* 
Plasma Field and 
Eye of the Storm allow Razor to chase Tusk after he uses Snowball.
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.
Tusk
* Queen Of Pain can similliar abilities from Anti-Mage 
Blink allows Queen of Pain to escape from an incoming Snowball and Ice Shards.
Undying
* Flak Cannon rips through Tombstone's zombies.
Additional:
* 
Flak Cannon enables Gyrocopter to clear the zombies easily.
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
* 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.
Additional:
* All abilities from Undying easy to steal to Rubick with 
Spell Steal.
Tusk
* After using Snowball, Tusk can't control where he's going, allowing Techies to make him roll onto mines.
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.
Additional:
* 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.
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.
Tusk
* Durable heroes can stand against Tusk during 1v1: 
Axe, 
Dragon Knight, 
Night Stalker, 
Centaur Warrunner, 
Wraith King and more.
Tusk
* 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.
Undying
* 
Meepo can quickly destroy Tombstone thanks to 
Divided We Stand.
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Undying
* 
Huskar's huge damage output and attack speed can get rid of Undying and Tombstone quickly.
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
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
* 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.
Undying
* 
Invoker's multiple spells can lock down Undying and disable him from doing much.
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.
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
Tusk
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, 
Earth Spirit, 
Faceless Void, Magnus, Mirana, 
Monkey King, 
Morphling, 
Pangolier, Phantom Assassin, 
Phoenix, 
Puck, 
Queen of Pain, Riki, 
Sand King, Spirit Breaker, 
Timbersaw, Tusk.
Undying
* 
Reactive Armor makes Timbersaw very effective against heroes that control a lot of units, such as 
Broodmother, 
Lycan and Undying.
Undying
* 
Terrorblade can destroy Tombstone with his 
Conjure Image and 
Metamorphosis.
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
* Mirana can destroy Tombstone, and evade zombies using Leap and Moonlight Shadow's invisibility.
Tusk
* 
Glimpse can return Tusk to where he was after using Snowball.
* 
Static Storm prevents Tusk from escaping with 
Snowball and when upgraded with Aghanim's Scepter, it will also prevent him from using items.
Tusk
* Tusk with Snowball
* Heroes that can dodge Glimpse:
* Puck with 
Phase Shift
* Riki with 
Tricks of the Trade
* 
Phantom Lancer with Doppelganger
* 
Ember Spirit with 
Sleight of Fist and 
Activate Fire Remnant
* Chaos Knight with Phantasm
* 
Naga Siren with 
Mirror Image
* Tusk with Snowball
* 
Juggernaut with 
Omnislash
* 
Brewmaster with 
Primal Split
* 
Lifestealer with 
Infest
* Phoenix with 
Supernova
Tusk
* 
Sticky Napalm makes it difficult for Tusk to hold his own on lane.
* An ill-timed and ill-positioned Snowball will give Batrider a free counter-initiation with 
Flaming Lasso if Batrider is far enough to avoid the stun from the Snowball.
Additional:
* Sticky Napalm makes it difficult for Tusk to hold his own on lane.
* An ill-timed and ill-positioned Snowball will give Batrider a free counter-initiation with Flaming Lasso if Batrider is far enough to avoid the stun from the Snowball.
Tusk
* 
Shadow Demon, 
Outworld Destroyer and Tusk can all save a Lasso'd teammate with their defensive spells.
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.
Tusk
* Snowball can protect Tusk and his teammates from a Spear of Mars' stun after an Arena of Blood, and with proper targeting, even bring them out of the Arena. This is especially noticeable in the earlier stages of the game before allies buy Black King Bar and rely on this less. Even during the late-game, Tusk can purchase a 
Blink Dagger to save allies that are caught before Black King Bars can be used by Blinking in and Snowballing out.
* 
Tag Team is a constant threat to Mars in-lane, as it deals significant damage and slow, making Bulwark slightly ineffective.
* It is worth noting that 
Ice Shards can be detrimental to Tusk's own team by creating terrain that Spear of Mars can latch on, though using it conservatively is a good enough solution in most cases.
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.
Tusk
* Snowball allows Tusk to easily cancel Freezing Field from a safe distance without putting himself in any danger.
* Walrus PUNCH! is most certainly a high enough damage nuke to easily kill off Crystal Maiden.
* Ice Shards can prevent the already immobile Crystal Maiden from escaping, making her an easy kill for either Tusk or a teammate.
Additional:
* Crystal Maiden's low health and armor make her an easy target for Walrus PUNCH!
* Tusk's Snowball can protect allies and cancel 
Freezing Field.
* Snowball and Walrus PUNCH! can interrupt Freezing Field.
Undying
* Anti-Tank heroes like: 
Razor, 
Necrophos, Undying.
Tusk
* Tag Team easily overwhelms Pudge, as he has low armor, which when combined with heroes with strong physical damage and Pudge's slow speed, it becomes for Pudge difficult to escape.
* Snowball can save a Dismembered ally and stop Pudge's Dismember.
* Walrus PUNCH! will removes a big chunk of Pudge's health and stun him.
* Pudge usually can't stand toe to toe against Tusk and his allies in the early game.
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
Tusk
* Shadow Fiend's lack of mobility and low base health make him an easy target for early ganks.
Tusk
* Ice Shards can easily interfere with Rolling Thunder, making him stuck inside the arc and wasting his ultimate. Do not panic and use Shield Crash to get out of that position.
* Snowball helps Tusk and his allies follow a fleeing Pangolier, keep in mind that the Pangolier can always counter-initiate with his Rolling Thunder.
* Walrus PUNCH! deals heavy damage even during his Rolling Thunder.
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.
Tusk
* Snowball can be used to save allies or himself during 
Venomous Gale and 
Poison Nova.
* Venomancer lacks mobility and has low base health, so he can be killed by Walrus PUNCH!
Tusk
* Tusks damage/stun is enough to obliviate Storm Spirit before he can do anything.
* Tusk is a common Blink Dagger carrier, and once he reaches Level 18, Walrus PUNCH! deals roughly half of Storm Spirit's health alone, It also stuns for a long enough time for Tusk to Snowball Storm Spirit, stunning him even more, If that hasn't finished him off, the damage from Ice Shards probably will. Combined with Tag Team, which adds bonus damage to Tusks attacks, Storm Spirit is unlikely to survive Tusk initiating on him
* Walrus PUNCH is even more potent if he uses a 
Silver Edge instead
* However while Ball Lightning doesn't disjoint Snowball, if used before Tusk hits with Snowball, prevents the stun and damage from being applied
Tusk
* Pugna's low health and reliance on channeled abilities make him very vulnerable to Tusk, although Pugna can win in a straight up 1v1 later in the game.
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.
Tusk
* 
Viper Strike can be countered through Snowball, wasting Viper's mana through his ultimate. It's Viper Strike's break is also useless because he has no passive abilties at all. And to make things worse, Viper Strike cannot disable Walrus PUNCH! because it's an auto-cast ability
* As Tusk is a natural Silver Edge wielder, he can use it to disable Viper's magic resistance from 
Corrosive Skin, and make him vulnreable to his other allies.
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.
Tusk
* Snowball and Ice Shards keep Drow Ranger down and preventing her from running away.
* Snowball also lets Tusk get to Drow Ranger and stop her Marksmanship bonus. It can also be to save allies affected by Gust.
* Tag Team allows Tusk to slow her down and land a killing blow on her.
* Walrus PUNCH! slows Drow Ranger and deals a huge amount of damage to her, due to her low health (and low armor without Marksmanship, since Tusk can quickly close the gap to Drow Ranger).
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.
Tusk
* Walrus PUNCH! can interrupt 
Black Hole and it can pierce spell immunity and neither Black King Bar nor 
Linken's Sphere can protect Enigma from Walrus PUNCH! as Walrus PUNCH! is an auto-cast ability.
* In pretty much any phase of the game, Tusk's abilities can easily cancel Black Hole and disrupt Enigma's positioning.
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.
Tusk
* Snowball negates 
Rupture and protects Tusk allies when Ruptured.
Tusk
* Tusk can 
Walrus Kick Monkey King out of Wukong's Command.
Additional:
* Tusk can Walrus Kick Monkey King from 
Wukong's Command, making his ultimate useless.
Tusk
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a 
Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, 
Warlock.
Tusk
* Heroes with high physical and magical damage alike are a huge hazard for Muerta, as they can deal serious damage to her even if she has 
Pierce the Veil active: 
Luna, 
Lina, Tusk, Broodmother, 
Shadow Fiend, Ember Spirit, Gyrocopter, 
Vengeful Spirit, 
Arc Warden, 
Medusa, 
Shadow Shaman.
Undying
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.
Tusk
* 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.
Tusk
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Tusk
* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, 
Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.
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.
Tusk
* Heroes with long range abilities are also able to touch Zeus, such as 
Clockwerk, 
Kunkka, Puck, 
Skywrath Mage, Spirit Breaker, Tusk and others.
Tusk
* Heroes with hiding abilities can protect disabled allies: Outworld Destroyer, Shadow Demon, Tusk, Phoenix with Aghanim's Scepter.
Additional:
* Bane has low mobility and health, making him an easy target for Walrus PUNCH!
* Walrus PUNCH! can be used to cancel 
Fiend's Grip if he is not the target.
Tusk
* Heroes with abilities that can save teammates are also effective such as Shadow Demon, 
Dazzle, 
Oracle, 
Bane, 
Pugna, Tusk, 
Winter Wyvern, 
Io, 
Underlord, 
Treant Protector and 
Keeper of the Light.
Tusk
* 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.
Tusk
* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker, Lifestealer.
Tusk
* Durable heroes can stand against Tusk during 1v1: Axe, Dragon Knight, Night Stalker, Centaur Warrunner, Wraith King and more.
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
* Sniper can easily destroy Tombstone from long range.
Tusk
* Snowball allows Tusk to move himself and allies towards Sniper whilst invulnerable and hidden.
* His Ice Shards may also block pathing for Sniper as he has no means of moving through obstacles. In addition, Tag Team can hinder Sniper's escape.
Additional:
* Tusk alone or with his teammates can close Sniper's long range easily with Snowball, even wasting Shrapnel, ending with a very vulnerable Sniper.
* Walrus PUNCH!'s very high physical damage output can easily kill Sniper instantly due to his low health and armor.
Undying
* Zombies summoned from Tombstone will amplify the damage of
Echo Slam due to them increasing the echo damage.
Tusk
*
Echo Slam is good against Snowball since it bunches everyone up. This can set up some prime opportunities for Blink Echo Slams.
