Drow Ranger
* 
Static Link weakens Drow Ranger's attack damage while strengthening Razor's attack damage.
* 
Plasma Field & 
Storm Surge keeps Razor close to Drow Ranger, continuously disabling Marksmanship.
Bristleback
* 
Eye of the Storm melts Bristleback's armor, and makes him much less tanky.
* Static Link can completely drain Bristleback's bonus damage from Warpath.
* Storm Surge allows Razor to outdistance Bristleback, even with a few stacks of Viscous Nasal Goo on him. Also, if Razor has his Shard, it will deal full damage to Bristleback every time he uses Viscous Nasal Goo (as Bristleback will face him to cast it).
Additional:
* Eye of the Storm melts Bristleback's armor, and makes him much less tanky.
* Static Link can completely drain Bristleback's bonus damage from 
Warpath.
Drow Ranger
* A well-timed 
Dark Pact can dispel Frost Arrows and Gust, letting Slark engage and escape freely.
* 
Essence Shift is very detrimental for Drow Ranger as the loss of agility means that Marksmanship will also suffer from getting weakened.
* 
Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* 
Pounce counteracts Frost Arrows's slow, and also allows Slark easily pin Drow Ranger down or flee from her.
* 
Depth Shroud from 
Aghanim's Shard will allow Slark to save both, himself and his allies and will also allow them to freely fight back against Drow Ranger without her noticing them.
Additional:
* Pounce and items like 
Shadow Blade makes it very difficult for Drow Ranger to keep her distance from Slark, thereby losing her 
Marksmanship bonus.
* 
Gust is rarely enough to keep Slark at bay, as Drow Ranger has no movement abilities and will simply be chased down afterwards.
* Drow Ranger's heavy dependence on agility also makes her significantly weaker after being drained by Essence Shift.
Bristleback
* Essence Shift allows Slark to hit Bristleback freely whether on the front or back, stealing attributes and make Bristleback much less tanky.
* Pounce can be used to disengage and recover lost HP with his ultimate passive, and can return to fight in a short period while Bristleback is already injured and got some of his attributes stolen.
* Dark Pact makes it near impossible to keep the 
Viscous Nasal Goo debuff on Slark.
* Although Dark Pact cannot dispel 
Quill Spray, meaning that Slark will still receive quill stack damage even if he used Shadow Dance before.
* Slark builds 
Silver Edge in almost every game, an item that greatly counters Bristleback.
Drow Ranger
* 
Time Walk can be used to close the distance within Drow Ranger, hindering her Marksmanship bonus.
* Faceless Void can also lock down Drow Ranger with 
Chronosphere before she has the chance to retaliate due to her low health pool.
Bristleback
* 
Time Dilation prevents Bristleback from spamming his low-cooldown abilities, greatly reducing his damage and effectiveness.
* Chronosphere allows allies to reposition and hit Bristleback from the front, bypassing his defensive bonus from behind.
* Bristleback has no way to prevent Void from using Time Walk.
Additional:
* Time Dilation while Quill Spray and Viscous Nasal Goo are on cooldown will make these abilities unusable for a long time, rendering Bristleback nearly useless.
* Bristleback cannot turn inside the Chronosphere, which makes it easy to attack him from the front, completely bypassing his passive damage reduction.
Drow Ranger
* 
Drow Ranger has a very low health pool, allowing 
Lion to burst her down.
* Lack of any innate escape mechanism makes her an easy target for Lion's disables.
* Early on she can't deal as much damage to be life threatning. Her Gust is her best weapon against Lion.
Bristleback
* Lion's 
Mana Drain is a headache for Bristleback to deal with during the laning stage, as it denies him the ability to get last hits with Quill Spray.
Drow Ranger
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: 
Sniper, 
Shadow Fiend, 
Troll Warlord, Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
Bristleback
* 
Shadow Demon's 
Demonic Purge with 
Aghanim's Scepter disables Bristleback's passives.
Drow Ranger
* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.
Bristleback
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: 
Axe, 
Pudge, 
Bristleback, 
Mars.
Drow Ranger
* 
Repel can be used to dispel Gust on the allies affected by it.
* In team fights, 
Guardian Angel renders Drow Ranger's physical damage useless, and Drow Ranger has no way to purge it. And to make thing worse, Drow Ranger is not a common 
Nullifier wielder to counter this problem at all.
Drow Ranger
* Another hero heavily based on attacks and no mobility, being an easy prey for Treant strong disarms and motion reduction skills.
Drow Ranger
* 
Laser along with 
Heat-Seeking Missile allows Tinker to quickly burst down Drow Ranger due to her low health.
* Heat-Seeking Missile lets Tinker out-range Drow Ranger and hit her in the backline of a teamfight.
Drow Ranger
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies completely on agility to be effective.
Drow Ranger
* Getting trapped in Power Cogs usually means the end for Drow Ranger.
Additional:
* 
Hookshot lets Clockwerk close the gap to Drow Ranger, disabling her Marksmanship bonus.
* 
Power Cogs and 
Battery Assault keep Drow Ranger from escaping.
* Power Cogs and Battery Assault also keep Drow Ranger close, nullifying Marksmanship.
Drow Ranger
* Nyx Assassin has a lot of burst damage from his 
Impale, 
Mind Flare, 
Dagon, and the bonus damage from 
Vendetta. All of this damage is enough to kill Drow Ranger.
* Nyx Assassin is usually invisible most of the time thanks to his ability Vendetta, which allows him to gank Drow Ranger easily.
* However, Gust is extremely dangerous for Nyx Assassin, as it's silence can render Nyx Assassin unable to lock down Drow Ranger. And if Gust hits Nyx Assassin while he is invisible with Vendetta, Drow Ranger will be able to detect him and foil his ganking attempts on her because Gust reveals invisible units.
Bristleback
* 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.
Bristleback
* 
Nethertoxin disables Bristleback's passive.
* 
Viper Strike and 
Poison Attack slow down Bristleback's movement speed, making him unable to get out from Nethertoxin.
Additional:
* Viper Strike can disable 
Bristleback and prevents Warpath from building stacks. Besides losing his defensive passive, Bristleback also loses his ability to build up damage over lengthy battles.
* Viper can perpetually kite Bristleback with Poison Attack and Viper Strike.
Drow Ranger
* Spectre can easily close the distance on Drow Ranger with 
Haunt and stick on her with 
Spectral Dagger, effectively disables her Marksmanship.
* Spectre does not care if silenced by Gust, since Spectre will catch her up regardless.
* 
Dispersion can reflect some damage back to Drow Ranger should she chooses to attack.
* Be careful once she got her Silver Edge as an attempt to shut you down.
Bristleback
* 
Guardian Sprint allows Slardar to outrun Bristleback, even when slowed by Viscous Nasal Goo.
* 
Corrosive Haze's armor reduction makes Bristleback much less tanky.
Bristleback
* 
Whirling Death deals damage while also reducing {Show:A|Timbersaw|Whirling Death|value4} of Bristleback's strength, making him less tanky.
* 
Reactive Armor can sustain through multiple Viscous Nasal Goo and Quill Spray stacks.
* 
Timber Chain makes it hard for Bristleback to slow down Timbersaw even with Viscous Nasal Goo.
Bristleback
* 
Phantom's Embrace silences Viscous Nasal Goo and Quill Spray.
* 
Ink Swell stuns Bristleback and gets allies in position faster with increased movement speed to attack his front, countering his passive ability.
Drow Ranger
* As long as Mars is facing her with Bulwark, even if pushed away with Gust, Drow Ranger will do no effectual damage against him. Mars' ability to endure her onslaught usually gives him enough time to cast Arena of Blood, of which she has a very slim chance surviving without Gust.
* With Bulwark's active ability, Mars can protect allies pursued by Drow Ranger by redirecting her projectiles to his shield instead.
Drow Ranger
* 
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).
Bristleback
* 
Sharpshooter deals massive damage to Bristleback and applies a high duration disable on his passive.
* 
Bushwhack and 
Scurry can be used to easily kite Bristleback.
Additional:
* Bristleback and Warpath can be disabled by Hoodwink's Sharpshooter ability for a long period of time, reducing his both offense and defense.
* Scurry and Bushwhack can be used to kite bristleback.
Drow Ranger
* Monkey King can scout Drow Ranger's positioning from the trees, and can jump on her without much trouble, disabling Marksmanship
* She lacks innate mobility to escape from Wukong's Command, whose bonus armor gives MK one extra edge in the fight
Drow Ranger
* Mirana can use Leap to jump right next to Drow Ranger or can approach her while under cover of the invisibility granted by Moonlight Shadow, which cancels the bonus granted to Drow Ranger by Marksmanship.
* Her low health makes her easy to burst down with Mirana's spells, especially with Aghanim's Scepter.
* Mirana can dodge Gust with good reaction time, or Leap away if Drow tries to slow her without Gust.
Drow Ranger
* Heroes with weaker mobility will struggle to keep up with Night Stalker: 
Gyrocopter, 
Ursa, Drow Ranger
Drow Ranger
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: 
Primal Beast, Axe, 
Centaur Warrunner.
Drow Ranger
* 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.
Drow Ranger
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, 
Lina, 
Rubick, etc.
Bristleback
* Heroes that withstand damage like 
Timbersaw, Bristleback, 
Dragon Knight and others will have their durability largely reduced when hit by an Ice Blast due to the risk of shattering.
Drow Ranger
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: 
Anti-Mage, 
Clinkz, Drow Ranger, 
Faceless Void, Gyrocopter, 
Juggernaut, 
Meepo, 
Mirana, 
Monkey King, 
Morphling, 
Phantom Assassin, 
Phantom Lancer, 
Riki, Shadow Fiend, 
Slark, Sniper, 
Terrorblade, Troll Warlord, 
Weaver.
Drow Ranger
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as Phantom Assassin, 
Spirit Breaker, and 
Tusk are effective at limiting her power and bursting her down.
Drow Ranger
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as Phantom Assassin, Spirit Breaker, and Tusk are effective at limiting her power and bursting her down.
Bristleback
* Spirit Breaker's 
Nether Strike with Aghanim's Shard disables Bristleback's passives.
Bristleback
* Heroes who can continue dealing damage even while being stunned: 
Luna, 
Razor, Axe, Bristleback, 
Leshrac, 
Death Prophet, 
Jakiro.
Drow Ranger
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, Axe, Centaur Warrunner.
Drow Ranger
* Heroes who outrange Drow Ranger such as Sniper, 
Tinker.
Drow Ranger
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, Clinkz
Drow Ranger
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's 
Pierce the Veil: Phantom Assassin, Terrorblade, Drow Ranger, 
Lifestealer, Anti-Mage, 
Alchemist, 
Lycan, Clinkz, Sniper.
Drow Ranger
* Range-reliant heroes: Sniper, Drow Ranger
Bristleback
* 
Batrider's turn rate slow from 
Sticky Napalm makes it harder for Bristleback to keep his back towards the enemy.
Bristleback
* Outworld Destroyer's high burst damage is not negated by Bristleback's passive. So, even if Bristleback turns his back on Outworld, he can decimate Bristleback quickly.
* If Bristleback attempts to flee, or tries to close the gap, Outworld can banish him with 
Astral Imprisonment, both reducing Bristlebacks much needed mana and allowing Outworld to move in front of him, forcing him to take the full damage from his spells. This will also allow Outworld to land a devasting Sanity's Eclipse, without it being reduced by Bristleback's passive.
Drow Ranger
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, 
Night Stalker, Drow Ranger, 
Doom .
Bristleback
* 
Arcane Curse stacks every time Bristleback uses an ability, forcing him to stop spamming his abilities, or take heavy health degeneration.
* 
Glaives of Wisdom steals intelligence both permanently and temporarily, causing mana issues for Bristleback.
* 
Last Word and 
Global Silence stops Bristleback from using his abilities altogether.
Additional:
* Bristleback will not be able to cast Viscous Nasal Goo or Quill Spray while silenced, effectively blocking a major part of the hero's damage and preventing Warpath charges from stacking.
* Arcane Curse slows Bristleback down and lasts longer the more abilities he uses. On the other hand, if he doesn't use any abilities, he will begin to lose Warpath charges.
Drow Ranger
* Heroes who rely on passive abilities and attacks, such as Drow Ranger, 
Wraith King, and 
Lone Druid, can render Silencer useless. But remember that a smart Silencer will most likely buy Silver Edge to counter this if he is played as carry.
Drow Ranger
* 
Berserker's Call forces Drow Ranger to attack Axe up close, disabling her Marksmanship bonus.
* 
Counter Helix occurs more often with Drow Ranger's high attack speed.
* 
Culling Blade is a dangerous ability against a low health hero like Drow Ranger.
Bristleback
* Axe forces Bristleback to turn around with Berserker's Call, allowing allies to attack him without fear of his passive.
Drow Ranger
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Bristleback
* Heroes who can stop Axe from getting close will severely inhibit his presence in fights: Bristleback, 
Crystal Maiden, Batrider, 
Arc Warden, 
Winter Wyvern, 
Clockwerk
Bristleback
* 
Reaper's Scythe and 
Heartstopper Aura deal percentage-based damage, ignoring Bristleback's high health.
* Heartstopper Aura's HP removal does not trigger Bristleback's passive.
Additional:
* Heartstopper Aura deals percentage-based damage flagged as HP removal, so it is not reduced by Bristleback, nor does it trigger passive Quill Sprays.
* Reaper's Scythe is very effective against Bristleback not only due to its percentage-based damage, but rather because it first stuns and then deals its damage, allowing Necrophos to position in front of Bristleback in time.
Bristleback
* Enemies that possess high defenses through magic resistance, damage reduction, or high regeneration will make it difficult to whittle their health down to get to Reaper's Scythe's threshold. Such heroes include Bristleback (although only from behind), 
Spectre, Ursa, and Dragon Knight.
Drow Ranger
* Often you can burst Drow Ranger down before she has a chance to try and Gust you away. Try to have a teammate bait her Gust out before you Blink and get the drop on her.
Drow Ranger
* Heroes reliant on abilities to output damage or escape can be shut down by Gust: 
Queen of Pain.
Drow Ranger
* Heroes with high base damage (Morphling, 
Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and 
Diffusal Blade users (Juggernaut or Riki) will suffer from Reflection's illusions.
Bristleback
* Terrorblade's 
Sunder is not affected by the Bristleback damage reduction.
Drow Ranger
* 
Metamorphosis will not match the range of Drow Ranger and he will struggle to do damage to her if she is not locked down already by someone else.
* 
Conjure Image will be destroyed very quickly due to Marksmanship.
* Terrorblade generally likes to be the big bad late game carry who sits in the middle of the fight and kills whoever is closest, which is very unlikely to be Drow Ranger therefore making it likely she will be going on him in teamfights.
* Terrorblade's high base armor and agility items makes him very vulnerable to Marksmanship.
Additional:
* Even though Drow Ranger's damage output is 100% physical, Marksmanship allows Drow Ranger to pierce Terrorblade's high natural base armor and when upgraded with Aghanim's Scepter, it will allow her to clear Terrorblade's illusions.
* Gust can prevent Terrorblade from using Sunder.
* Since Terrorblade doesn't like to buy armor items like 
Assault Cuirass, he will be very vulnerable to Drow Ranger's high physical burst damage.
Drow Ranger
* A well-timed Gust will prevent Rubick from casting abilities from 
Spell Steal, and his lack of capabilities and low health pool usually dies very quickly.
* Drow Ranger can dispel 
Fade Bolt's reduction debuff with 
Manta Style.
Bristleback
* Bristleback's abilities are nearly useless for Rubick to Spell Steal, as he does not gain the bonuses from Warpath.
Additional:
* Rubick deals little damage on his own, and Bristleback can simply shrug off all his spells and chase Rubick down with his Quill Spray and the damage bonus from Warpath.
* Rubick does not tend to charge forward in teamfights, stay in the front lines under most circumstances, yet effective casts of Quill Spray and Viscous Nasal Goo requires the opposite as they require multiple casts and close range to add up stacks.
* Rubick does not benefit from Warpath through casting the stolen spell.
Drow Ranger
* Dragon Knight has no built-in disengage from 
Frost Arrows, and Marksmanship procs ignore base armor, bypassing Dragon Knight’s durability for the most part, making Drow one of the few heroes that can deal enough sustained damage to solo kill Dragon Knight.
* With Aghanim's Scepter, Frost Arrows also apply hypothermia stacks, reducing her target’s regen, which is especially potent against tanks like Dragon Knight. (A similar effect can also be achieved with an 
Eye of Skadi).
Bristleback
* Viscous Nasal Goo slows down Dragon Knight and lowers armor, locking him down and making him more vulnerable.
Drow Ranger
* Gust can hit Dark Willow beyond a defensive Bramble Maze, and before she gets close enough to hit Drow Ranger with Bedlam.
* Drow Ranger's long range allows her to hit Dark Willow's team without venturing into her Bramble Maze.
Bristleback
* Quill Spray's constant AoE damage will hit Dark Willow even in Shadow Realm. Its automatic damage will hurt her if she tries to get close and use Bedlam.
Drow Ranger
* A well-timed Gust will prevent Windranger from escaping or counter-initiating with 
Windrun.
* Drow Ranger commonly buys Shadow Blade or Silver Edge, which allows her to escape from 
Focus Fire. 
Monkey King Bar, a situational item on Drow Ranger, counters Windranger's evasion from Windrun.
* The bonus agility from Marksmanship can shred through Windranger's low armor.
Additional:
* A well-timed Gust prevents Windranger from escaping or counter-initiating with Windrun.
* Drow Ranger can combine Frost Arrows and Eye of Skadi to effectively slow down Windranger if she tries to escape with Windrun, since both slow effects stack with each other.
* Drow Ranger commonly buys Shadow Blade or Silver Edge, which allows her to escape from Focus Fire. Drow Ranger can also buy Monkey King Bar or Nullifier to counter Windranger's evasion from Windrun.
* The bonus agility from Marksmanship can shred through Windranger's low armor.
Bristleback
* Combo Quill Spray and items 
Blade Mail can easily trigger from Focus Fire damage.
Additional:
* Using Focus Fire on Bristleback tends to fare badly for Windranger, as he can trigger passive Quill Sprays many times, especially when she attacks him from behind. In addition, Windrun does not protect her from both Viscous Nasal Goo and Quill Spray, rendering her helpless.
* Bristleback's natural tankiness makes it hard for Windranger to effectively burst her down throughout the game.
* Bristleback tends to continuously spam Viscous Nasal Goo to slow down Windranger when she uses Windrun to escape, potentially allowing him to outrun her with his Warpath stacks.
* Bristleback can build 
Lotus Orb to reflect Shackleshot and Focus Fire back at Windranger.
Drow Ranger
* 
Black Hole while definitely a threat to Drow Ranger, is very hard to land as she likes to keep her distance from allies and enemies alike. And if not caught in it, will kill Enigma very quickly due to his low health.
* 
Malefice can be removed with a Manta Style.
* Drow Ranger being a fairly low health, high armored agility carry doesn't take much damage from 
Midnight Pulse as others would.
* 
Demonic Conversion units die very quickly to Marksmanship or even just regular attacks not far into the game within 2 or 3 hits.
Bristleback
* Bristleback's constant harass from Quill Spray will greatly hurt Enigma's laning and kill his Eidolons.
* However, Bristleback has no way of canceling Black Hole at all. And Bristleback is not a hero that goes for disabling items to counter that problem.
Drow Ranger
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Bristleback
* 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.
Drow Ranger
* Heroes with low health are especially vulnerable to Marksmanship's high damage output: Clinkz, Crystal Maiden.
Bristleback
* 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.
Drow Ranger
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: Arc Warden, 
Chen, Clinkz, Drow Ranger, Lina, Mirana, 
Nature's Prophet, 
Pugna and Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
Bristleback
* Heroes with damage-over-time abilities easily allow Bristleback to turn his back in order to proc Bristleback continuously and to massively reduce to damage dealt to him: Arc Warden, 
Venomancer, Luna.
Drow Ranger
* Every hero that can withstand or prevent Eclipse at level 7: Juggernaut, Riki, Clockwerk, Drow Ranger, 
Abaddon, Faceless Void, Weaver, 
Outworld Destroyer.
Bristleback
* Heroes with damage-over-time abilities easily allow Bristleback to turn his back in order to proc Bristleback continuously and to massively reduce to damage dealt to him: Arc Warden, Venomancer, Luna.
Additional:
* 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, and her only way to counter this is by buying Silver Edge.
* Viscous Nasal Goo and Warpath are enough to outrun a speedy Luna.
* Bristleback tends to be a frequent carrier of 
Crimson Guard and 
Eternal Shroud, which are good protection from 
Moon Glaives and 
Eclipse.
* For the same reasons, Bristleback makes a very powerful ally for Luna when they are in the same team.
Bristleback
* 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
Drow Ranger
* Clinkz has no stun and likes to keep his distance from targets, making Marksmanship very deadly.
* Clinkz also has low health, making him a perfect hero to initiate onto with Gust.
* Gust can also prevent Clinkz from using 
Burning Barrage.
Bristleback
* Quill Spray usually hits Meepo's clones, although Bristleback cannot turn his back when rooted with 
Earthbind.
Drow Ranger
* Gust can shut down most of Dawnbreaker's abilities, rendering her useless.
* Frost Arrows followed by a high attack speed, makes it hard for Dawnbreaker to escape.
Drow Ranger
* Drow Ranger can use Gust to push back Juggernaut before he can get in range to use 
Omnislash or 
Blade Fury.
Bristleback
* 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.
Bristleback
* Fortune's End cannot dispel Warpath stacks on Bristleback or Quill Spray stacks on allies.
* Bristleback can heavily reduce Oracle's damage output. With it, Oracle may accidentally heal Bristleback with Purifying Flames, especially if Bristleback has bonus magic resistance.
Drow Ranger
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, Drow Ranger, 
Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
Bristleback
* Heroes that have AoE damage: Lina, 
Keeper of the Light, Timbersaw, Leshrac, Bristleback, Axe.
Drow Ranger
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, 
Templar Assassin, Arc Warden
Bristleback
* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, Doom: 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.
Drow Ranger
* Heroes with silence: Death Prophet, Riki, Drow Ranger.
Drow Ranger
* As a spellcaster, silences will nullify him entirely. Some notable examples are Death Prophet, Drow Ranger, 
Bloodseeker, 
Disruptor and many others.
* 
Doom, as usual, fits this description nicely.
Drow Ranger
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as 
Silencer, Drow Ranger and Death Prophet.
Bristleback
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback, Clinkz, Luna,Shadow Fiend, 
Slardar, Terrorblade
Drow Ranger
* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: Bloodseeker, Death Prophet, Silencer, Drow Ranger, 
Skywrath Mage.
Bristleback
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: 
Tidehunter, Bristleback, Slardar.
Drow Ranger
* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: Drow Ranger, 
Bane, 
Necrophos, Crystal Maiden.
Additional:
* 
Reality Rift will disable Drow Ranger's Marksmanship, along with 
Chaos Bolt he can keep her locked for enough time to be killed.
Bristleback
* Quill Spray quickly destroys Chaos Knight's 
Phantasms.
Drow Ranger
* 
Phantom Rush lets Phantom Lancer get close quickly and disable Marksmanship.
* As Phantom Lancer commonly buys Manta Style, he can easily dispel Gust and then chase after Drow Ranger.
* Because Phantom Lancer is a natural Diffusal Blade carrier, he can easily burn Drow Ranger's mana and render her unable to use Frost Arrow and Gust to save herself.
Bristleback
* 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 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.
Additional:
* 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.
Bristleback
* 
Infernal Blade deals scaling damage and is useful against high health targets such as Bristleback.
* Doom disables Bristleback's low cooldown abilities, preventing him from triggering Warpath. With his upgraded level 25 talent, it also breaks Bristleback's passive, rendering him more vulnerable.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Bristleback.
* Doom prevents Bristleback from casting his two low cooldown abilities, which then prevents him from utilizing Warpath.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can disable Bristleback and Warpath, taking away much of his durability and damage potential in team fights.
Drow Ranger
* Drow Ranger can be difficult to get on top of, thanks to her Frost Arrows and Gust. With these two abilities, Drow Ranger is able to effectively 'kite' Doom and minimize his impact during team fights and laning stage.
* Much of Drow Ranger's effectiveness comes from her passive Marksmanship, which is not disabled by Doom.
Drow Ranger
* Morphling can use Waveform to close the gap between him and Drow Ranger, but should be careful of Gust and Frost Arrows.
* Morphling is a natural Manta Style carrier, which dispels the silence from Gust.
Drow Ranger
* 
Attribute Shift (Strength Gain) may not be quick enough to fend off an attacking Drow Ranger.
* Morphling likes to sit on low health with high agility, something Drow Ranger does not particularly care for and will still hit him hard with Marksmanship procs.
* 
Morph is a similar story, none of Drow Ranger's spells are particularly good against her.
Bristleback
* Mana Break quickly eats away at Bristleback's small mana pool, preventing him from spamming Viscous Nasal Goo and Quill Sprays.
* Bristleback has no innate mobility. Bristleback is easily kited by Blink, ignoring the protection from Bristleback.
Additional:
* 
Mana Break removes both a percentage and flat amount of your mana, preventing Bristleback from using abilities in the lane.
* 
Blink Anti-Mage has very high mobility with this skill, and can easily escape from Bristleback since he has no way to prevent his blink. He can also use this offensively to get in front of Bristleback during fights.
Drow Ranger
* None of Anti-Mage's skills are that effective against Drow Ranger. Gust prevents him from Blinking in or out, 
Counterspell is totally useless against Drow's physical damage, and as she usually doesn't have a high mana pool, Mana Break and 
Mana Void don't do much either.
* Be careful however that Anti-Mage may eventually farm enough to Blink on top of you and kill you straight away, considering you have no natural tools to escape from him.
Bristleback
* 
Shukuchi gets Weaver in front of Bristleback, negating the protection from Bristleback.
* Weaver's mana break talent depletes Bristleback's mana pool, preventing him from spamming abilities.
Drow Ranger
* A well-timed Gust will prevent Weaver from escaping, and a silenced Weaver usually dies very quickly.
* Weaver gains a lot of armor, which is bypassed by Marksmanship.
Additional:
* A well-timed Gust followed by Frost Arrows will prevent Weaver from escaping with Shukuchi. A Weaver silenced for more than 3 seconds usually dies very quickly.
* Due to her high attack speed, Drow Ranger can easily kill The Swarm beetles.
Bristleback
* While Jakiro's damage is going to be little more then average against him due to his Bristleback. His large quantity of stuns can prevent Bristleback from getting his much needed Warpath stacks, while also giving his allies a chance to counter his high defense.
* Dual Breath and Liquid Frost both reduce Movement Speed, removing one of Bristlebacks greatest strengths.
* Liquid Fire reduces Bristlebacks Attack Speed, making it harder for him to burst down a hero with Warpath.
* However Bristleback can generally catch and kill a lone Jakiro. And Jakiro is only effective in a group.
Bristleback
* 
Macropyre's frequent damage ticks causes Bristleback to activate repeatedly, resulting in free damage as long as Bristleback faces away from Jakiro.
Drow Ranger
* 
Meat Hook brings Drow Ranger to Pudge, disabling Marksmanship and dealing a huge amount of damage when combined with 
Rot and 
Dismember.
* Rot keeps Pudge close to Drow Ranger, continuously disabling Marksmanship.
Additional:
* Meat Hook can pull Drow Ranger to Pudge, disabling her Marksmanship.
* Following up with Dismember will prevent Drow Ranger from using Gust or Shadow Blade.
Bristleback
* 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.
Additional:
* 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.
Drow Ranger
* 
Blink Strike gets Riki close to Drow Ranger and disable Marksmanship.
* 
Cloak and Dagger allow Riki stay close to Drow Ranger without her noticing him, which allows him to disable Marksmanship.
Additional:
* With Blink Strike, Riki can get close to Drow Ranger and disable her Marksmanship, and Smoke Screen will prevent her from using Gust.
Bristleback
* 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.
Additional:
* 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.
Drow Ranger
* 
Shapeshift allows Lycan to get close and disable Marksmanship.
* Shapeshift also makes him immune to slows like Drow Ranger's Frost Arrows.
Additional:
* The Wolves's speed causes the knockback from Gust to be ineffective.
* Drow Ranger lacks escapes and loses her Marksmanship when someone is near her. Lycan can take advantage of these weaknesses of Drow Ranger.
Bristleback
* Lycan's wolves deal little damage to Bristleback, and are easily killed by Quill Spray, even when they're invisible.
* Lycan's lack of burst damage makes it very hard for him to kill Bristleback, especially when his back is turned.
Additional:
* 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.
Drow Ranger
* 
Life Break closes the distance between Huskar and Drow Ranger, dealing large amounts of damage and disabling Marksmanship.
* 
Berserker's Blood and 
Burning Spear allow Huskar to beat Drow Ranger directly and pile on damage.
Bristleback
* 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.
Additional:
* 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.
Drow Ranger
* Drow Ranger's lack of escape abilities makes her an easy target for Relocate ganks.
Bristleback
* 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.
Drow Ranger
* Magnetic Field protects Arc Warden and allies from Drow Ranger's ranged attacks. She most likely will not enter the field since she will lose Marksmanship's bonus agility.
* Beware however, as Marksmanship procs will still hit since they have True Strike, so the most damaging arrows will still hit you inside Magnetic Field.
Additional:
* 
Flux along with 
Spark Wraith allows Arc Warden to quickly burst down Drow Ranger due to her low health.
* However, Drow Ranger can bypass 
Magnetic Field's evasion bonus thanks to Marksmanship.
Bristleback
* Arc Warden has relatively lower armor and mobility, which makes him an easy target to apply Quill Spray and Viscous Nasal Goo stacks.
* Arc Warden also does not like to build a Silver Edge as it takes a long time to build up and may slow down the timings for other important items needed in the game like 
Gleipnir.
* However, do note that in a game where Arc Warden's team has many jumping capabilities or good passives, like a Tidehunter or Spectre, a Silver Edge becomes incredibly valuable on Arc Warden as not only can he run away from the jumps, he effectively gets 2 breaks, and Bristleback may not be the best pick.
Drow Ranger
* Drow Ranger's lack of mobility and area-of-effect abilities makes her easy prey for Broodmother and her Spiderlings.
Bristleback
* 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.
Additional:
* 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.
Drow Ranger
* Invisible heroes are very difficult for Drow Ranger to deal with such as 
Bounty Hunter, Riki and heroes who commonly buy a Shadow Blade.
Bristleback
* 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.
Drow Ranger
* Drow Ranger's low mobility and lack of defensive abilities make her an easy gank target in the early to mid-game.
Marksmanship, reduce her damage output significantly, and will more likely lose that Duel.
* A Dueling Drow Ranger will lose her precious
Bristleback
*
Duel makes Bristleback fight Legion Commander face to face, forcing him to take full damage.
Press the Attack dispels the slow from stacks of Viscous Nasal Goo.
Bristleback to come into effect.
*
Additional:
* When dueled, Bristleback will have to face Legion head on, not allowing his passive
