Puck
* Generally strong against every spellcaster, Puck fully relies on their skill set and is barely a threat when silenced.
* 
Arcane Curse disables Blink Dagger for quite some time, and is also effective against Puck as it tend to use its spells a lot.
* 
Glaives of Wisdom can do a lot of damage against Puck due to Puck's low agility gain and armor.
* 
Last Word can prevent Puck from getting a full combo off, limiting its effectiveness in team fights or ganks.
* 
Global Silence can take Puck out of fights entirely.
Warlock
* Because Warlock's abilities are all active abilities, Silencer can make his impact minimal.
* Arcane Curse prevents Warlock from using his abilities without increasing it's duration, which since all of Warlock's abilities are actives it is very effective against him.
* Last Word can prevent Warlock from casting his Fatal Bonds, Chaotic Offering, and Upheaval combo.
* Global Silence can nullify Warlock's impact in fights by preventing him from casting Fatal Bonds and Chaotic Offering, or by interrupting his Upheaval.
Puck
* All abilities from Puck potentialy can easily stealing with 
Spell Steal. Rubick's can build 
Blink Dagger inisiate escaping from Puck.
* With 
Aghanim's Scepter, Rubick's can easily two stolens abilities from Puck's.
Additional:
* 
Illusory Orb and 
Waning Rift are all great wave-clear abilities.
* Waning Rift can silence 
Puck, disabling all her abilities including 
Phase Shift.
* 
Dream Coil is a powerful teamfight ultimate that leashes enemies and disables their movement.
* As an elusive hero who requires constant repositioning, Puck is greatly countered by her own ultimate as it disables all her mobile abilities and items (especially Blink Dagger), forcing Puck to either stay in the danger zone or latches and stuns for a long time.
* Although Phase Shift does not provide extra damage or lockdown on its own, it does grant Rubick invulnerability, and enables him to use Blink Dagger with full duration similar to Puck's escaping combos.
* Rubick can initiate on Puck relatively fast as 
Telekinesis only has a 0.15 second cast animation.
Warlock
* Spell Steal can perfect steals all abilities for Warlock primarily Chaotic Offering.
* Rubick always purchase Aghanim's Scepter will additionally Rubick's instanly Chaotic Offering stolen although Warlock's without purchase Aghanim's Scepter.
* Telekinesis can cancelled Upheaval lift up Warlock's and also can cancel from Upheaval with nearby creeps and enemy hero from Telekinesis can throw and touch down to Warlock's. Additionally, Telekinesis can save allies from Upheaval trap will upgrade with 
Aghanim's Shard .
Additional:
* Spell Steal can easily stealing from 
Chaotic Offering is a better position. Build Aghanim's Scepter and 
Octarine Core make cooldown reduction abilities from Rubick and addition instanly Warlock's Golem from Chaotic Offering stollen.
* Telekinesis from Rubick can help stopped from 
Upheaval chancelled. Telekinesis also stopped from Upheaval with throw creeps and enemy hero touch down to Warlock. Rubick's can build Aghanim's Shard save the his allies trapped from Upheaval.
* Upheaval can stollen for Rubick passing positionning area from Upheaval. Alternative, already from Chaotic Offering via Spell steal also possible cancelled from Upheaval with ready build Aghanim's Scepter capable of stealing two abilities from Warlock's.
* 
Shadow Word stollen for Rubick can very helpful restore health from his allies. Addictionally, for Shadow Word stollen can reduction health from enemy heroes.
* 
Fatal Bonds makes Rubick simplify fighting from target.
Puck
* Jakiro has 3 damage over time spells, 2 of which are from debuffs on Puck (
Dual Breath and 
Liquid Fire) and 1 affecting an entire area (
Macropyre), making it easy for him to disable the blink dagger.
* 
Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.
Additional:

* Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.
Warlock
* Heroes with channeling spells are very easy targets for Jakiro's abilities: 
Crystal Maiden, 
Dawnbreaker, 
Enigma, 
Pudge, 
Shadow Fiend, 
Shadow Shaman, 
Warlock.
Puck
* 
Doom can shut down with all abilities and items from Puck is strong escape. Since Doom muted silence activated duration, Puck Can't move freely although Doom build item Aghanim's Scepter.
* Doom will use build item Blink Dagger and 
Silver Edge can important from Doom simply catch Puck.
Warlock
* Supports with useful teamfight or contribution spells will be helpless against Doom: 
Dazzle, 
Oracle, Warlock.
Puck
* A Lycan with 
Shapeshift can always run down Puck for a very quick kill due to its low armor. It is important to abuse as many cliffs and trees as possible to escape from a Lycan.
Warlock
* Shapeshift allows Lycan to escape from Upheaval with maximum movement speed.
* Warlock doesn't have a good solution to deal with Lycan's wolves from 
Summon Wolves.
Puck
* Any Hero with high mobility will be neutralized by dream coil: 
Queen of Pain, 
Storm Spirit, 
Ember Spirit, 
Lycan, 
Bloodseeker, 
Anti-Mage, 
Timbersaw
Puck
* 
Riki and 
Disruptor: 
Smoke Screen and 
Static Storm can be thrown wherever Puck used Phase Shift, making Puck an easy target if it doesn't have Blink Dagger or is on cooldown. Puck is also very susceptible to Riki's high attack damage when attacking from the back. Glimpse also prevents Puck from escaping.
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include 
Chaos Knight, 
Spirit Breaker, Riki, and more.
Puck
* 
Bristleback, 
Centaur Warrunner, Spirit Breaker, Pudge, 
Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

Warlock
* Ghostship helps your team soak up damage from Chaotic Offering and hit summons hard.
* Tidebringer clears summons later in the game.
* Most of your spells can interrupt Upheaval.
Puck
* Stone Form's long stun duration may prevent Puck from using escape abilities.
* Visage frequently builds 
Rod of Atos for the root that will make Puck unable to move and use his escape abilities. Alternatively, Visage can also build 
Bloodthorn to prevent Puck from using his escape abilities and make him more vulnerable to damage.
Puck
* 
Void is a potent nuke that is devastating to Puck's low health pool.
* 
Crippling Fear silence can prevent Puck from casting spells, leaving it vulnerable.
Additional:
* Puck cannot use any of its normal means to survive should Night Stalker catch it within Crippling Fear, and goes down quickly.
Puck
* Arc Warden can turn Puck's Phase Shift ability against him by using 
Spark Wraith, ensuring it to hit. To make this worse, Arc Warden can do it twice with his 
Tempest Double.
* 
Flux is also an instant spell (and therefore unavoidable) with a heavy slow and damage over time, which disables Blink Dagger for a certain period of time.
Puck
* Waning Rift's silence is almost completely worthless against Wraith King, due to him having only 1 active ability.
* Wraith King's only active ability, 
Wraithfire Blast, is strong against Puck if it hits, because it applies a damage over time on top of stunning and doing impact damage, disabling Puck for a while, and Blink Dagger for even longer. It is very important to avoid getting hit by this spell when playing against Wraith King.
Puck
* Unless Puck is facing the direction he wants to blink while in Phase Shift, the 
Venomous Gale and 
Poison Nova combo consistently ticks many times over several seconds, making it very difficult to use Blink Dagger towards the other direction. Puck's slow turning rate makes this even worse.
Warlock
* 
Surge allows for Dark Seer and his allies to escape from Upheaval due to it ignoring any slow.
Warlock
* 
Ice Blast cancels Warlock's Golem's and Shadow Word's healing.
* 
Cold Feet stuns Warlock if he stands in place, forcing him to stop channeling Upheaval immediately or be forced to stop channeling it by it's stun.
Warlock
* Weaver's 
Shukuchi allows him to escape from Warlock's Upheaval with high move speed.
* 
Time Lapse allows Weaver to ignore damage from Warlock's Golem and escape.
Puck
* Hard lockdowns such as 
Chronosphere can end a Puck's life quickly. A Puck stunned for longer than 3 seconds usually ends up dead.
* As the type of hero that spams spells, 
Time Dilation counters Puck very effectively. Phase Shift is Puck's main ability for survivability, and Time Dilation effectively triples its cooldown.
* If not silenced, 
Time Walk can easily undo the damage dealt by Illusory Orb, Dream Coil and Dagon.
Additional:
* Puck cannot use spells if affected by Time Dilation, especially Phase Shift for main survivability as it effectively triples its cooldown.
* Chronosphere can end Puck's life quickly, as stun, more than 3 seconds will be a death sentence to Puck.
* If not silenced, Faceless Void can just Time Walk to undo Puck's Burst damage.
Puck
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, 
Void Spirit, 
Mars.
Puck
* 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.
Warlock
* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, 
Witch Doctor, Warlock or Shadow Fiend.
Puck
* Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Warlock
* Heroes who rely on summons will see them destroyed easily by Overwhelming Odds: Lycan, 
Arc Warden, Warlock, 
Chen
Puck
* 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.
Warlock
* Upheaval does not interrupt Slark too much, as he can just Pounce out of the area.
* Fatal Bonds and Shadow Word can be dispelled by Dark Pact.
Puck
* Illusory Orb and Phase Shift allows Puck to avoid most ganking attempts.
* Waning Rift and Dream Coil makes it very hard for Slark to escape bad situations.
* Puck's abilities used together also deals significant magical nuke damage, none of which are targeted and thus cannot be avoided by Shadow Dance.
Puck
* Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Puck
* 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.
Puck
* Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Warlock
* With God's Strength, Warlock Golem goes down in a matter of seconds. The two weaker golems granted by Aghanim's Scepter will fare worse due to Great Cleave hitting both.
* Storm Hammer upgraded with Aghanim's Scepter dispels Shadow Word.
Additional:
* 
God's Strength combined with 
Great Cleave destroys Chaotic Offering golems within seconds.
* 
Warcry gives Sven and his allies armor to help against Warlock's Golem's heavy physical damage and movement speed to help escape Upheaval.
* 
Storm Hammer disrupts Upheaval.
Puck
* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like 
Sven, Lifestealer, 
Ursa and 
Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.
Warlock
* A pre-placed 
Fire Remnant allows Ember Spirit to escape Upheaval.
* 
Flame Guard blocks Shadow Word's damage.
* 
Sleight of Fist allows Ember Spirit to attack from outside of Upheaval's range, and 
Searing Chains lets him interrupt it.
Puck
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw
Puck
* 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.
Warlock
* Warlock has strong counter initiation which reduces Marci's effectiveness throughout the game.
* Fatal Bonds cancels Blink Dagger, which means Marci can move in and out of fights less effectively.
* Chaotic Offering paired with Upheaval provides a ministun, a movement slow and paired with Fatal Bonds has the potential to deal a lot of damage to Marci while she jumps on a target. The ministun also means that Marci will have a harder time casting Rebound. If Warlock does build Aghanim's Scepter and 
Refresher Orb, the physical damage from Golems will overwhelm Marci, especially when played as a support.
Puck
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, 
Invoker, Magnus, Puck, and Sand King.
Warlock
* Fatal Bonds links the Meepos together, which combined with area of effect damage or Cleave will be devastating.
Puck
* Phase Shift allows Puck to dodge all of Earthshaker's abilites.
* Waning Rift disables Earthshaker's stuns, leaving him and his team vulnerable.
* Dream Coil takes a stun from Earthshaker if he tries to escape from Blink Dagger or Enchant Totem upgraded from Aghanim's Scepter.
Warlock
* Warlock often stays back and counter-initiates by dropping his Chaotic Offering on Earthshaker and his allies.
Puck
* Puck relies mainly on magical burst damage, which Phantom Assassin is most vulnerable against.
* Phase Shift and Illusory Orb disjoint Stifling Dagger, also allowing to kite Phantom Assassin.
* Dream Coil will stun Phantom Assassin if she uses 
Phantom Strike to blink away.
Warlock
* 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.
Puck
* Heroes that are hard to kill without lockdown: Puck, 
Weaver.
Warlock
* 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.
Additional:
* Because Shadow Fiend lacks escaping mechanisms, and is dependent on fair positioning for channeling 
Requiem of Souls, it's easier for Warlock with his long range crowd control abilities to lock Shadow Fiend down for his team.
Puck
* Low health spellcasters: 
Lina, Witch Doctor, 
Tinker, 
Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Warlock
* Channeling heroes will not go well against Warlock, especially those who build 
Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Puck
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; Spirit Breaker, 
Legion Commander, 
Axe, Puck, and 
Slardar.
Puck
* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.
Warlock
* Chaotic Offering's spell immunity piercing stun can stop Black Hole's channeling. Due to this ability's large area of effect, it can be cast at a safe distance from the Black Hole. It also goes through Black King Bar and ignores 
Linken's Sphere.
* Fatal Bonds and Aghanim's Shard upgraded Shadow Word can be used to make Enigma's Eidolons easier to kill, potentially feeding the enemy team. Also,their constant damage will put Blink Dagger on cooldown, potentially forcing Enigma to prematurely activate Black King Bar.
Additional:
* Chaotic Offering pierces spell immunity and is an area of effect ability, therefore it doesn't matter if Enigma buys Black King Bar or Linken's Sphere, Warlock will always be able to cancel the channeling of 
Black Hole.
* Enemies often get clumped up around Black Hole to hit your allies, giving you a perfect opportunity to cast Fatal Bonds, Chaotic Offering, and Upheaval on multiple enemies.
Puck
* Heroes with mobility spells like Queen of Pain, Anti-Mage, Phantom Assassin, Riki, Puck, and Spirit Breaker that are cancelled by Frostbite can suffer greatly from the presence of Crystal Maiden. It is absolutely critical, however, to have followup from teammates, as all of the above heroes can make quick work of the squishy Crystal Maiden after they are released from her grip.
Puck
* Puck has both Waning Rift and Dream Coil to stop 
Freezing Field's channel regardless of whether or not Crystal Maiden has a Glimmer Cape, as both spells fully affect invisible units.
Warlock
* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.
Puck
* Backline supports (
Lion,Crystal Maiden) keep him pinned long enough for a kill.
Puck
* Waning Rift silences and damages enemies affected by the ability, diminishing Lion's punishing powers.
* High burst damage potential plus mobility and disable through Illusory Orb, Waning Rift, and Dream Coil allows Puck to effortlessly chase, lock and/or kill Lion, as the Demon Witch lacks proper ways to avoid so.
* Phase Shift allows Puck to dodge 
Earth Spike, 
Finger of Death and breaks 
Mana Drain's link.
Warlock
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: Huskar, 
Drow Ranger, Lion, 
Elder Titan, etc.
Puck
* All of Puck's damaging spells deal AoE magic damage, which focuses on Terrorblade's low health pool and ignores his armor.
* Puck's spells are also great at quickly clearing all of Terrorblade's illusions. Even a single Illusory Orb is enough to drop their health very low, allowing creeps, towers or allies to finish them off very quickly. Waning Rift and Illusory Orb together are usually enough to clear his illusions.
* Waning Rift prevents Terrorblade from casting 
Sunder at low health.
* Puck is a common 
Dagon carrier, making it possible to finish off Terrorblade before he has a chance to Sunder.
Warlock
* Chaotic Offering's vast area-effect can destroy trees and stun Hoodwink.
* Upheaval makes retreating with 
Scurry difficult.
Puck
* Dream Coil leash can stop and stunned moving from 
Windrun.
* Combinated Wanning Rift and build Blink Dagger can easily avoid from 
Focus Fire
Puck
* 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.
Puck
* Puck can initiate on Mirana with Waning Rift to prevent her from going invisible or Leaping.
* A Mirana caught in Dream Coil will stun herself if she tries to Leap away.
* Puck's Burst damage takes advantage of Mirana's below average health.
* Puck can easily dodge Sacred Arrow and Starstorm with Phase Shift.
Additional:
* Mirana's spells are laid out to assassinate enemies. Puck can easily avoid the slow moving 
Sacred Arrow, and also can avoid 
Starstorm with Phase Shift, since the meteors have a delay.
* If Puck casts either Waning Rift or Dream Coil in the area, Mirana cannot 
Leap away.
Puck
* Sniper has no spells to disable Puck. He lacks a silence to prevent spell casting and a stun to disable, allowing Puck to act instantly against Sniper.
* Sniper's main strategy is to attack his enemies from safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get to Sniper. Due to his low health, he is also easily nuked down by Puck.
* The status debuff placed by 
Assassinate on its target makes it very easy to avoid it. Puck has 2 (3 when having Blink Dagger, 4 when having Eul's Scepter of Divinity, 5 when having Linken's Sphere) methods to disjoint or dodge the projectile, making it a bad spell for finishing off Puck.
Puck
* All of Puck's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Shadow Demon will find a hard time catching a Puck, as he can get away with Illusory Orb or even Waning Rift;
* Puck can dodge Shadow Poison waves and potentially avoid the damage from Demonic Purge with Phase Shift. Furthermore, after Disruption ended, Puck can use Phase Shift to avoid any further danger and can blink away with Blink Dagger.
* Waning Rift can be used to initiate Shadow Demon, prevent him from using any spells.
Puck
* Dream Coil and Wanning Rift prevent Pangolier from using 
Swashbuckle and 
Rolling Thunder. If Puck has Aghanim's Scepter, Dream coil will stop Rolling Thunder from moving entirely.
Additional:
* Illusory Orb and Waning Rift provides great mobility, allowing Puck to catch up Pangolier when he is attempting to disengage with his own skills.
* Dream Coil's leash act almost as a literal silence to Pangolier, disabling half of his arsenal and also piercing his spell immunity during Rolling Thunder. Also Dream Coil's very long duration will make Pangolier wasting his entire ultimate rolling in place.
Puck
* All of Puck's abilities are area-targeted, and will hit Dark Willow when she uses Shadow Realm.
* Illusory Orb allows Puck to bypass Bramble Maze, close the gap and silence Dark Willow with Waning Rift.
* Phase Shift helps Puck dodge attacks charged by Shadow Realm, and is easily timed against Terrorize's long cast time..
Puck
* Although Phoenix has many ways to disable a Blink Dagger, the high cooldown of all of its spells makes them not as reliable for this. Also, its spells cost a lot of health to use, making it easy to get nuked down.
* Waning Rift prevents Phoenix from using 
Supernova to refresh itself, giving Puck's team time to finish it off, or allow Puck to burst Phoenix down.
* Dream Coil prevents Phoenix from using 
Icarus Dive without consequences. Waning Rift and Dream Coil are also able to cancel 
Sun Ray, which is its main source of damage in the late game.
Puck
* Phase Shift can easily disjoint Phantom Embrace and waste half of the Soulbind's duration.
* Puck is very mobile hero who can jump backsides and burst Grimstroke before he can cast anything.
Puck
* Illusory Orb and Waning Rift are effective nukes against Phantom Lancer's illusions, especially in the early game.
* Dream Coil limits Phantom Rush and Doppelganger's mobility during teamfights.
Puck
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw
Puck
* Heroes with silencing abilities that are not blocked by Linken's Sphere, like Puck's Waning Rift, 
Death Prophet's 
Silence or 
Silencer's Global Silence.
Puck
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw
Warlock
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.
Puck
* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Puck
* 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.
Puck
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, 
Slark etc.
Warlock
* Chaotic Offering can stop heroes who like to use spell immunity and teleport scrolls to safely farm during the early to mid game, since it stuns and also goes through spell immunity. Notable examples: Juggernaut, Lifestealer.
Puck
* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Puck
* Heroes who can dodge Earth Spirit's abilities: Ember Spirit, Puck, Weaver
Puck
* 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.
Puck
* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.
Warlock
* Chaotic Offering can stop heroes who like to use spell immunity and teleport scrolls to safely farm during the early to mid game, since it stuns and also goes through spell immunity. Notable examples: Juggernaut, Lifestealer.
Puck
* Puck silences Ogre Magi with Waning Rift, and Phase Shift makes Puck untargetable for the duration.
Puck
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw
Puck
* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.
Warlock
* Viper cannot interrupt heroes with powerful channeling abilities: Bane, Enigma, Shadow Shaman, Warlock
Warlock
* 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.
Puck
* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.
Puck
* Heroes with long range abilities are also able to touch Zeus, such as 
Clockwerk, 
Kunkka, Puck, 
Skywrath Mage, Spirit Breaker, Tusk and others.
Warlock
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: Huskar, Drow Ranger, Lion, Elder Titan, etc.
Puck
* Low health spellcasters: Lina, Witch Doctor, Tinker, Keeper of the Light, all rely heavily on their spells and are fragile heroes. They all also have avoidable spells, allowing Puck to get to them and quickly burst them down.
Puck
* Mass summoning heroes: Broodmother, Nature's Prophet and Enigma all have summons Puck can clear clear with Illusory Orb and Waning Rift instantly, due to their summons having low health.
Warlock
* Illusion and heroes with summons are difficult to kill with Chen's single-target offensive spells: Terrorblade, Phantom Lancer, Chaos Knight, Broodmother, Naga Siren, Lycan, Visage, Beastmaster, Warlock, Wraith King. And even though Chen can convert enemy summons with Holy Persuasion, their much greater numbers will often overwhelm Chen and his creeps.
Puck
* Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
Warlock
* Warlock Golems do plenty of physical and pure damage to bring down Huskar when he is at low health. Warlock is always a hazard for Huskar to initiate by using 
Life Break, because Chaotic Offering can stun him instantly, even when Black King Bar is activated, and allows Warlock's team to gather their wit and retaliate.
* After using Life Break to jump in, Huskar will not have any means to escape Upheaval. Which since he is an attack-dependent hero, this will nullify his impact in fights.
Warlock
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some Heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Puck
* Puck's area of effect nukes in the form of Illusory Orb and Waning Rift clears Phantasm illusions from the early game to mid game.
* Phase Shift can be used to disjoint Chaos Bolt.
Puck
* Riki and Disruptor: Smoke Screen and Static Storm can be thrown wherever Puck used Phase Shift, making Puck an easy target if it doesn't have Blink Dagger or is on cooldown. Puck is also very susceptible to Riki's high attack damage when attacking from the back. Glimpse also prevents Puck from escaping.
Puck
* Puck with Phase Shift
* 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
Warlock
* 
Mana Break prevents Warlock from casting his spells, particularly in the laning phase.
* 
Blink allows Anti-Mage to escape from Upheaval.
* 
Counterspell reduces damage from Shadow Word and Warlock's Golem's 
Permanent Immolation passive. Additionally, it can reflect Shadow Word and Fatal Bonds.
* 
Mana Void deals heavy damage after Anti-Mage has drained Warlock's large mana pool.
Puck
* Waning Rift silences Anti-Mage, preventing him from blinking away.
* However, Waning Rift can be dispelled by Manta Style.
* Dream Coil stops Anti-Mage from blinking, with Aghanim's Scepter also locks down Anti-Mage for long duration.
Warlock
* Ursa can shred Warlock's Golems in a few seconds with 
Fury Swipes and 
Overpower.
Puck
* Melee heroes that get kited easily have hard times dealing with Puck without any lockdowns, as Puck is one of the most mobile heroes. Heroes like Sven, Lifestealer, Ursa and Alchemist may have problems to get to Puck without proper initiation items. They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.
Puck
* None of Puck's abilities have any damage-over-time components, meaning that 
Refraction is a valuable form of defense against Puck's lane harassment.
* 
Psi Blades deals pure damage and spills over instantly. Puck cannot reliably dodge the damage with Phase Shift.
Additional:
* Puck high magical burst is almost completely useless against Refraction. Templar Assassin often buys 
Orchid Malevolence to render Puck useless in teamfights.
Warlock
* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, 
Ancient Apparition, 
Grimstroke, Witch Doctor
Puck
* 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.
Warlock
* Warlock can cast Upheaval when Templar Assassin uses 
Meld, preventing her from escaping at the right moment.
* Warlock can also send his Warlock Golem near where she used Meld, preventing escape by Blink Dagger due to the Warlock Golem's Permanent Immolation.
* Warlock's Golem's Permanent Immolation will burn away Refraction with its damage over time.
Warlock
* Because all of Warlock's abilities are active abilities, silences can make his impact in fights minimal. Be cautious of heroes that carry silences like Death Prophet, Puck, and the aforementioned Silencer.
Puck
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, Morphling.
Puck
* Once you farm up an Orchid Malevolence or a 
Scythe of Vyse, you're suddenly a lot more fearsome to elusive heroes like Storm Spirit or even that pesky Puck.
Puck
* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw
Additional:
* Puck will make a game of dodging as many Shadow Strikes as he can with Phase Shift. If he's a good player, he will also dodge Sonic Wave. If he's a great player, he will also dodge Scream of Pain. All through a single spell.
* Puck also has a silence to stop her blink with Waning Rift.
* Puck will have vision to hunt her down if she blinks into the trees with Illusory Orb.
* If Queen of Pain is under the effect of Dream Coil, she will be unable to blink out.
Puck
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, 
Lich, Magnus, Mars, 
Medusa, 
Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, 
Treant Protector, 
Underlord, 
Winter Wyvern, Witch Doctor, 
Zeus.

Brain Sap: Broodmother, Chaos Knight, Naga Siren, Nature's Prophet, Phantom Lancer, Terrorblade, Visage, Warlock, Wraith King.
Puck
* Nyx Assassin can take advantage of every one of Puck's weaknesses. His entire skill set is very effective in countering Puck.
Spiked Carapace, stunning Puck and setting up an easy 
Impale. This can be circumvented by using Phase Shift while the orb is traveling, however, that means that Puck cannot use Phase Shift to dodge any other skill nor use it to safely blink away from a fight.
Eul's Scepter of Divinity, 
Scythe of Vyse, and 
Dagon. This makes 
Mind Flare that much more deadly against Puck.
Impale.
Illusory Orb is easy to reflect with Spiked Carapace, either stunning Puck and setting up an easy Impale or forcing a premature 
Phase Shift.
Phase Shift can easily set Puck up to be stunned by Impale.
* Because Illusory Orb is such a slow moving projectile, Nyx Assassin can simply walk into the orb and activate

Warlock
*
Impale and 
Spiked Carapace interrupts Upheaval with ease.
* Warlock's low health pool, mobility, and high intelligence gain makes him a prime target for Nyx Assassin's burst damage.
