* 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..

* 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.

* Bristleback's tankiness and damage reduction from the rear makes him very hard for Phantom Lancer to chase and finish off, due to his lack of burst damage.
* Quill Spray destroys Phantom Lancer's illusions.
* Bristleback's passive costs no mana, meaning that it will continue to trigger even if Phantom Lancer drains Bristleback's mana with Diffusal Blade.
Additional:

* Quill Spray quickly destroys Phantom Lancer's illusions.
* Bristleback's passive costs no mana, meaning that it will continue to trigger even if Phantom Lancer drains Bristleback's mana with Diffusal Blade.

* Quill Spray usually hits Meepo's clones, although Bristleback cannot turn his back when rooted with Earthbind.

* 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.

* 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.

* Bristleback reduces most of Broodmother's and her spiderlings' damage.
* Quill Spray will hit any spiders in its proximity, hindering Broodmother's fighting and farming capabilities.
Additional:
* Quill Spray destroys spiderlings, and hits Broodmother even when she's regenerating in her webs. This makes Bristleback one of her hardest counters in lane.

* Viscous Nasal Goo can hinder Crystal Maiden's already abysmal mobility, which allows Bristleback (or his teammates) to run her down and kill her.
* Bristleback frequently builds Blade Mail, which can quickly kill Crystal Maiden if her ultimate is used while he is under its effect.
* The passive part of Bristleback will trigger many, many times under the damage from Freezing Field, and as the stacks increase, the damage output from each successive cast (or proc) will eat away at Crystal Maiden's small HP pool.

* 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.

* 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.

* Heroes that have AoE damage: Lina, Keeper of the Light, Timbersaw, Leshrac, Bristleback, Axe

* 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.

* Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.

* 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.

* Bristleback's abilities are nearly useless for Rubick to Spell Steal, as he does not gain the bonuses from Warpath.

* 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.

* Quill Spray will hit Sand King inside Sand Storm, damaging him and putting Sand King's Blink Dagger on cooldown, preventing him from escaping.
* Epicenter's numerous damage ticks will trigger Bristleback's passive repeatedly during teamfights.

* Tiny's nonexistent armor in the early game makes him very vulnerable to Quill Spray's large amounts of physical damage.
* Bristleback decreases Tiny's high burst damage against Bristleback.
* Viscous Nasal Goo can slow Tiny to a crawl and allows Bristleback to easily kite him with his high movement speed and Quill Spray's long range, as Tiny has no ability to escape.

* Quill Spray is very effective against Io, as it has very low armor and has to stay close to the fight to not break its Tether.

* 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.

* Quill Spray and Bristleback harass Luna more efficiently than she does with Lucent Beam.
* Bristleback helps return a lot of damage to Luna’s team if she uses her nukes on him and he has his back to her.
* Viscous Nasal Goo and Warpath are enough to outrun a speedy Luna.
* Bristleback tends to be a frequent carrier of Crimson Guard, which is good protection from bouncing glaives.

* 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.

* 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 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.

* Bristleback's constant harass from Quill Spray will greatly hurt Enigma's laning and kill his Eidolons.

* 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.

* Lone Druid and The Spirit Bear cannot burst down Bristleback due to Bristleback
* Bristleback can easily run to Lone Druid without any hesitation, with Viscous Nasal Goo to reduce armor and slow the Spirit Bear or Lone Druid and Quill Spray can deal damage to both Lone Druid and the Spirit Bear at the same time

* 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.

* 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.

* 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 silences Ogre Magi with Waning Rift, and Phase Shift makes Puck untargetable for the duration.

* Windranger heavily relies on her abilities for any form of tactical advantage and damage. A well timed silence will make her useless: Puck,Silencer, Death Prophet, Skywrath Mage, Drow Ranger, Earth Spirit, Grimstroke.

* Heroes that are hard to kill without lockdown: Puck, Weaver.

* 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.

* 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.

* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.

* Bristleback's Viscous Nasal Goo can catch and slow Bounty Hunter. Warpath and Quill Spray can defeat him quickly due to his small HP pool when compared to Bristleback's.

* 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.

* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, Slardar {Hero ID:Terrorblade}

* 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.

They also lack reliable lockdowns, as their disables are easily avoidable for Puck, or are just a soft disable.

* 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.

* Quill Spray can be used to kill Lycan's summons.
* Bristleback allows him to stay alive against Lycan while dishing out counter attacks
* He can overpower Lycan with his Warpath instead.
Additional:
* Lycan's wolves deal little damage to Bristleback, and are easily killed by Quill Spray, even when they're invisible.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw

* 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 usually builds Eul's Scepter of Divinity to dispel Shadow Poison and Soul Catcher and Linken's Sphere to block Disruption and Demonic Purge.

* 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.

* 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.

* Pudge is particularly susceptible to Bristleback's Viscous Nasal Goo and Quill Spray due to his naturally low armor and poor agility gain.
* Bristleback, in combination with his strength gain, high health, common itemization for magic resistance and damage reduction from Bristleback makes him a poor target for Pudge.
Additional:
* Bristleback is one of the hardest heroes to gank with a Meat Hook and Dismember combo, and attempts to do so sometimes backfire on Pudge.

* Bristleback's tankiness and Bristleback allow him to outlast Burning Spears' damage-over-time at almost any point in the game. In addition, if Huskar chooses to cast Life Break on Bristleback, Bristleback can simply turn around before it hits and receive little damage.
* Viscous Nasal Goo will reduce Huskar's low armor even further, and Quill Spray and Warpath will tear him down extremely quickly.
Additional:
* The damage from Burning Spear can be reduced by turning away from Huskar.
* Bristleback can bait Huskar into using Life Break on him, then turn around and receive very little damage.

* The bonus Backstab damage from Cloak and Dagger is rendered irrelevant with Bristleback and hurts Riki more than him because of the passive Quill Spray.
* Riki can still get damaged by Bristleback's Quill Spray while invisible, and it can be hard to deal with in lane.
* Bristleback is not too bothered by Smoke Screen. Though he cannot use Quill Spray manually inside it, it still procs passively when he takes damage from the back. The movement speed from Warpath allows him to get out of the area easily.
* Due to Bristleback's natural tankiness, he is an ideal Gem of True Sight carrier.
* Riki rarely buys Silver Edge to break Bristleback's passive because the invisibility aspect of it is redundant.
Additional:
* Quill Spray will hit Riki even when he is invisible.
* Cloak and Dagger's bonus backstab damage is rendered irrelevant against Bristleback.
* Smoke Screen does not stop Bristleback's passive from activating.
* Due to Bristleback's natural tankiness, he is an ideal Gem of True Sight carrier, directly countering Riki's invisibility.

* 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.

* Any Hero with high mobility will be neutralized by dream coil: Queen of Pain, Storm Spirit, Ember Spirit, Lycan, Bloodseeker, Anti-Mage, Timbersaw

* 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.

* 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.

* Heroes who can slow and kite Axe will severely inhibit his presence in fights: Bristleback, Crystal Maiden, Batrider, Arc Warden, Winter Wyvern, Clockwerk

* 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.
