Silencer
* Heroes with damage-increasing passive abilities, such as 
Viper and 
Riki, will usually kill Silencer in a short time before he even has time to set up his abilities.
Lone Druid
* Riki: 
Smoke Screen can prevent Lone Druid from using True Form and Savage Roar, additionally it cause the spirit bear to miss on attacks which reduce the chances of getting rooted from it, with diffusal Blade, he can keep Lone Druid or the Spirit Bear inside the Smoke.
Silencer
* Rage can protect Lifestealer from most of the Silencer's abilities with the exception of 
Global Silence, as it will still silence if cast while the target is magic immune. However, it will not work if Lifestealer is infesting a unit.
* Silencer is vulnerable to Open Wounds due to his lack of an innate escape.
* Against a carry Silencer, 
Aghanim's Scepter upgraded 
Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
Additional:
* 
Rage can protect Lifestealer from most of the Silencer's abilities with the exception of Global Silence.
* If Lifestealer can Infest himself on any unit, he can literally avoid being affected by Global Silence.
* Against a carry Silencer, Aghanim's Scepter upgraded Infest can disarm him and allow Lifestealer to attack Silencer from within, even if Silencer is spell immune.
* 
Open Wounds from 
Aghanim's Shard can severely slow down Silencer, and allow Lifestealer and his team to heal themselves by attacking Silencer.
Lone Druid
* 
Cold Embrace can protect allies from Lone Druid and the Spirit bear, who mainly deal physical damage
* 
Winter's Curse can turn Lone Druid and the Spirit Bear against his teammates.
Silencer
* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: 
Lich, 
Crystal Maiden, 
Silencer, 
Keeper of the Light, 
Venomancer, etc.
Lone Druid
* Huskar jumps on the hero without any problems, throwing the 
Summon Spirit Bear away from him and forbidding him to beat, which knocks down the regeneration of Lone Druid from the 
Spirit Link ability, in addition, Huskar instantly deals fatal damage to Lone Druid, in some cases he does not even have time to squeeze the 
True Form

Silencer
* Heroes with pure damage can kill Huskar when he inevitably gets low on health: 
Outworld Destroyer, Silencer.
Silencer
* Broodmother relies less on abilities and more on right-clicks.
* Spiderlings can overwhelm Silencer, who has mediocre armor and no escape tool.
Silencer
* Silencer relies on preventing enemies from using abilities in teamfights with Arcane Curse, Last Word, and Global Silence. However, they are ineffective against Ursa since he relies more on items and attacks than abilities.
* Against a carry Silencer, 
Enrage can help Ursa reduce all damage he takes, even Glaives of Wisdom's pure damage will just tickle Ursa while his Enrage is active.
Silencer
* 
Last Word is extremely easy to reflect with Spiked Carapace for large amounts damage, due to triggering when Nyx Assassin casts a spell, but can still silence Nyx Assassin. It also has the added bonus of dealing more damage the more Intelligence Silencer has.
* 
Glaives of Wisdom quickly builds Silencer's Intelligence, making him a particularly prime target for Mana Burn.
* Silencer rarely builds survivability items, nor is he able to steal much Intelligence while surrounded by his team, and so is an excellent target for Vendetta.
* Silencer has no reliable way of dealing with a burrowed Nyx, and also lacks the ability to prevent Nyx from escaping with Vendetta,
Additional:
* Silencer is rather squishy and has poor mobility without items, making him an easy target for Nyx.
* Silencer's intelligence steal ability is a complete disadvantage against Nyx Assassin as 
Mind Flare will deal increasing damage for each point of intelligence Silencer has stolen, turning Silencer's intelligence steal against him.
Silencer
* 
Shapeshift is useful for killing or escaping Silencer.
* 
Summon Wolves, can be used to hunt and harass silencer - even when Lycan himself can't fight.
Silencer
* If Silencer can't prevent Dragon Knight from using 
Elder Dragon Form, Silencer's spells aren't going to be that effective against him, as Dragon Knight relies on right-clicks and not spells.
* 
Dragon Blood's armor bonus and health regeneration allows Dragon Knight to stay in the lane against Glaives of Wisdom.
* Dragon Knight often builds 
Black King Bar, allowing him to remove Global Silence before engaging.
Lone Druid
* Brewmaster can make the Spirit Bear a much smaller threat with Cinder Brew.
* Cyclone removes the bear from a fight so that his team can easily focus on the hero.
* While most heroes would be worn down by a Spirit Bear 
Radiance in the time it takes to kill Lone Druid, Brewmaster is protected in Primal Split.
Silencer
* Even though carry Silencer can easily take down a support Jakiro with his Glaives of Wisdom, Jakiro can also do the same to Silencer if he is not careful and if Jakiro is not played as support. As Silencer is rather squishy and lacks escape mechanisms without items, and Jakiro's damage over time abilities can take advantage of this.
* 
Ice Path can be used to prevent Silencer from escaping. And if Jakiro uses Ice Path along with 
Macropyre and 
Dual Breath in anticipation right before Silencer uses his abilities to disable Jakiro, Jakiro will be able to kill Silencer before he even gets a chance to do anything to Jakiro.
* Dual Breath, 
Liquid Fire and 
Liquid Frost from Aghanim's Shard can greatly reduce Silencer's attack speed.
* Aghanim's Scepter upgraded Macropyre can deal huge pure damage to Silencer even if Silencer is spell immune.
* Bear in mind, however, that Jakiro should approach Silencer carefully as Silencer's 
Arcane Curse, Last Word and Global Silence prevents Jakiro from casting any spell. Jakiro, however, can counter this by going for 
Guardian Greaves, a common item on support Jakiro, and with Black King Bar and 
Manta Style, a situational items on Jakiro.

Lone Druid
* Grimstroke's 
Soulbind will always reliably connect onto both of them if they are close together.
Lone Druid
* 
Firestorm's percentage damage can quickly demolish the Spirit Bear's high HP
* 
Pit of Malice will allow allies to easily kite Lone Druid due to his low mobility
Lone Druid
* Reality Rift lets Chaos Knight bypass the Spirit Bear and jump onto Lone Druid.
* The Spirit Bear's lack of scaling means it dies quickly to Chaos Knight during the late-game.
Silencer
* Due to Sniper having a such a long range, he will rarely get hit by any of Silencer's spells.
* Global Silence will not hinder Sniper much as other heroes since most of his damage output comes from his attacks.
Additional:
* Sniper is a pure right click carry with a very long range, making it hard for Silencer to cast any of his skills on him in lane. During team-fights, Global Silence has little impact on Sniper.
Silencer
* Shadow Fiend is mostly played as right-click carry and natural Black King Bar carrier, making Silencer's spells very ineffective against him.
Silencer
* Silencer's low mobility and lack of any stuns or roots makes him an easy target.
* Silence will not protect Silencer from Jingu Mastery's extra damage and lifesteal.
* Monkey King often buys Black King Bar, which can be used to negate silence debuff effects.
Lone Druid
* Tiny can be a serious problem for the distance between Lone Druid and his Summon Spirit Bear with his 
Toss ability, since he will throw one away from the other, giving his team the opportunity to deal with either the Summon Spirit Bear or Lone Druid himself
* Lone Druid will not always be in his True Form, since she has her own recharge, which is why Tiny can find him with a 
Shadow Blade or 
Blink Dagger and kill him in a second with a combination of 
Avalanche and Toss, due to the fact that Lone Druid has a very small health reserve without True Form
Additional:

Lone Druid
* Unless Lone Druid purchases a Black King Bar for his Spirit Bear, Ensnare will easily kite the Spirit Bear.
* Song of the Siren allows Naga Siren and her team to completely bypass the Spirit Bear and hunt for the Lone Druid himself when starting a fight.
* Lone Druid's lack of innate AoE capabilities mean that Naga Siren's illusions have no problem against him.
Silencer
* 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.
Silencer
* Heroes that can disable or silence Silencer for a long time, such as 
Bane and 
Legion Commander, can lock down Silencer while their allies put him down.

Lone Druid
* 
Clinkz, 
Sniper, Lone Druid, 
Troll Warlord, Legion Commander and Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Silencer
* Heroes with damage-increasing passive abilities, such as Viper and Riki, will usually kill Silencer in a short time before he even has time to set up his abilities.
Lone Druid
* Chain Frost can deliver high amounts of damage to Lone Druid itself and his bear if they do not separate fast from each other.
Additional:
* 
Chain Frost will bounce between Lone Druid and his bear, forcing them to separate or suffer high amounts of damage.
Silencer
* 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.
Silencer
* Slark's 
Dark Pact allows him to dispel Silencer's debuffs.
* Against a carry Silencer, 
Essence Shift will lower damage from both Glaives of Wisdom and his basic attack.
Silencer
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer, Death Prophet, 
Puck, 
Doom.
Silencer
* Phantom Assassin doesn't care about Silencer's spells as she relies on right-clicks more than spells.
* Phantom Assassin often builds Black King Bar, which allows her to remove Global Silence before engaging.
Lone Druid
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: 
Templar Assassin, 
Phantom Assassin, 
Ember Spirit, 
Morphling.
Silencer
* Global Silence and Last Word can prevent Ember Spirit from casting Activate Fire Remnant to escape.
* Glaives of Wisdom also provide high pure damage that is not negated by Flame Guard.
* Arcane Curse is also a potent harassing tool in the laneing stage as its cooldown is lower than Flame Guard's.
Lone Druid
* Lone Druid becomes unkillable and impenetrable for Ember Spirit on the central line, as it has a huge reserve of health from the Summon Spirit Bear and a large regeneration from Spirit Link, which is why 
Sleight of Fist practically does not break through either one or the other on the line, and Lone Druid at this time can easily expel Ember Spirit from the line, push and gain gold and level
* 
Entangling Claws and 
Savage Roar abilities completely disable Ember Spirit's ability to dodge abilities or get out of an unpleasant fight for him on 
Fire Remnant, which can give the Lone Druid team the opportunity to kill him

* Entangling Claws and Savage Roar abilities completely disable Ember Spirit's ability to dodge abilities or get out of an unpleasant fight for him on Fire Remnant, which can give the Lone Druid team the opportunity to kill him
Silencer
* Generally strong against lots of spellcaster-themed heroes, Puck fully relies on its skill set and cannot do almost anything when silenced.
* Arcane Curse disables Blink Dagger for quite some time, and is also effective against Puck as it tends 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 because of its long-duration silence.
Lone Druid
* Lone Druid has a huge reserve of health on the Summon Spirit Bear and a quick regeneration of his health with the help of Spirit Link, which makes the Puck's magical abilities useless, since they cannot break through such a large pool of health
* The ability of the Summon Spirit Bear and in the True Form of the Lone Druid Entangling Claws allows you to catch Puck when he released the 
Illusory Orb, since Puck will not be able to apply 
Ethereal Jaunt during the root action
Additional:
* Lone Druid has a huge reserve of health on the Summon Spirit Bear and a quick regeneration of his health with the help of Spirit Link, which makes Puck's magical abilities almost useless, since they cannot break through such a large pool of health.
* The ability of the Summon Spirit Bear and in the True Form of the Lone Druid, Entangling Claws, allows him to catch Puck when it releases the Illusory Orb, since Puck will not be able to apply Ethereal Jaunt during the root.
Silencer
* Invoker is heavily dependent on his spells, making him useless during Global Silence, as well as interrupting Invoker during his combo.
* Arcane Curse is particularly deadly, because Invoker will continuously lose health if he keeps invoking and casting new spells.
* Last Word will silence Invoker when he casts Invoke, interrupting his combo.
Lone Druid
* Lone Druid has a very large reserve of health against Invoker abilities, this allows him to survive a large number of attacks from Invoker and kill him, also Entangling Claws reveal invisibility from 
Ghost Walk, which allows the Lone Druid team to catch the popular QW-Invoker
Additional:

Silencer
* Basically, Heroes that heavily rely on abilities for damage or escape, such as 
Queen of Pain and 
Storm Spirit.
Additional:
* Silencer's 
Intelligence Steal can reduce Storm Spirit's damage output if he gets some kills on laning phase.
* Last Word and Global Silence will make Storm Spirit an easy target.
* Global Silence can be used to prevent Storm Spirit from connecting abilities after a Ball Lightning on his targets.
Lone Druid
* True Form gives Lone Druid a huge amount of health that no amount of 
Ball Lightning will chip through.
* Entangling Claws can mean a very quick end to the Storm Spirit as it prevents him from using Ball Lightning all together.
* Storm Spirit is a single target nuker, with the Shard Lone Druid can always fear him away from himself or the bear, defending the target he does not go on. This is assuming he cannot try and proc his entangle or a potential 
Skull Basher.
Silencer
* Shadow Demon's main source of damage is his low cooldown, high damage spells - meaning Last Word and Global Silence will pretty much take him out of the game for the duration.
* Shadow Demon likes to spam his abilities, which makes him vulnerable to Arcane Curse.
* If Shadow Demon dies near Silencer, he will lose intelligence, reducing his mana pool, mana regen, and attack damage. Furthermore, if the game is long and Shadow Demon dies often, the intelligence losses will also reduce his spell damage.
Lone Druid
* 
Chaos Knight, Lone Druid, 
Meepo and 
Arc Warden can be hard targets since Shadow Demon's spells are ill-suited to fight many enemies at once.
Silencer
* Crystal Maiden is squishy, is heavily spell reliant, has low base Intelligence, and is naturally slow, making her an ideal target for Silencer.
* Crystal Maiden's 
Freezing Field has a similar cooldown to Global Silence, therefore, Freezing Field can almost always be canceled to ruin aggressive Crystal Maiden initiations.
Lone Druid
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: 
Ancient Apparition, Crystal Maiden, 
Shadow Shaman, etc.
Silencer
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
Lone Druid
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.
Silencer
* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: 
Invoker, Silencer, 
Nyx Assassin, Skywrath Mage, Shadow Shaman, 
Lion and etc.
Lone Druid
* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.
Silencer
* Arcane Curse makes it too difficult Lina from using her abilities, preventing her from building up Fiery Soul stacks without causing harm to herself.
* Last Word and Global Silence are great against Lina for the same reason, as well as interrupting her combos and preventing her from casting spells.
Lone Druid
* Besides Lone Druid and Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
Silencer
* Heroes with low mana pools (eg.Doom and
Tidehunter) will feel the effects of Silencer's Intelligence Steal far more than others.
Lone Druid
* Lone Druid is essentially two heroes. Dooming one over the other still leaves Lone Druid or his bear able to do their job during a fight. Additionally, Lone Druid is not hindered as much as other heroes by the silence and mute of Doom since the hero relies more on attacks than abilities.
Additional:
* Doom will be very hestitant to use 
Doom on the Spirit Bear, and using it on Lone Druid himself will not stop the bear from attacking him especially if True Form has already been used.
* 
Devour does not work on the Spirit Bear and pushes the lane so Lone Druid can safely farm under tower.
Silencer
* Silencer's abilities hamper Windranger's effectiveness in battle, preventing her from comboing abilities and escaping using 
Windrun.
Additional:
* Glaives of Wisdom's intelligence steal can prove detrimental to Windranger, as she heavily relies on her abilities to be able to make an impact.
* Silencer's abilities hamper Windranger's effectiveness in battle, preventing her from comboing abilities and escaping using Windrun.
Silencer
* Both Arcane Curse and Last Word punishes casters with spammable spells such as Sand King.
* As a strength caster, Intelligence Steal reduces Sand King's mana pool even more.
* Global Silence silences Sand King, effectively reducing Sand King's initiation and counter-initiation potential. It can also interrupt channeling of Epicenter.
Lone Druid
* Once caught in Bear's Entangle, Nature's Prophet cannot escape with 
Teleportation.
Silencer
* Global Silence stops Snapfire's 
Mortimer Kisses.
* Last Word can prevent Snapfire from casting additional spells.
Silencer
* Glaives of Wisdom's intelligence steal will heavily punish Queen of Pain, as the loss of intelligence means that her mana pool is also reduced, since she is heavily reliant on her abilities to be able to make an impact.
* In the laning stage, Queen of Pain's reliance on spamming Shadow Strike and Scream of Pain will be significantly hindered by Arcane Curse.
* Last Word and Global Silence will render Queen of Pain defenseless unless she has an item/ally to dispel the silence.
Silencer
* Global Silence has faster-cast animation than Chronosphere, making Silencer can silence Faceless Void before he can cast Chronosphere.
Silencer
* Being a cast-oriented hero, Ezalor will suffer from all of Silencer's abilities.
* Global Silence is a guaranteed lengthy silence which will render Ezalor useless in a teamfight.
* Arcane Curse and Last Word are good against any caster, since they are extremely potent.
* However, it should be worth mentioning that a smart Ezalor will buy Eul's Scepter of Divinity to dispel Silencer's abilities. Combined with the level 20 talent (Chakra Magic applies a basic dispel), Ezalor can purge Silencer's abilities off allies and himself alike.
Silencer
* Terrorblade is a double-edged sword type of matchup against Silencer. Although Terrorblade is more reliant on direct attacks to be effective, he relies on 
Sunder to save himself and stay alive and Last Word and Global Silence prevent him from doing that.
* Arcane Curse and Aghanim's Scepter upgraded Last Word help Silencer deal with Terrorblade's illusions from 
Conjure Image and Manta Style.
* With Last Word Mutes talent, Silencer can not only disable Terrorblade from turning tables with Sunder, but can also prevent him from using Manta Style and Black King Bar, items Terrorblade needs to be effective in teamfights.
* Glaives of Wisdom deals pure damage against the real Terrorblade, bypassing his high base armor.
* Global Silence can silence Terrorblade even if he has Black King Bar active, though bear in mind that Terrorblade can dispel Global Silence with Manta Style and Black King Bar if the Global Silence was activated first.
Additional:
* Silencer is a double-edged sword type of matchup against Terrorblade. Although Terrorblade is more reliant on direct attacks to be effective, he relies on Sunder to save himself and stay alive and Last Word and Global Silence prevent him from doing that.
* Arcane Curse, Glaives of Wisdom upgraded with 2 Glaives of Wisdom Bounces talent and Aghanim's Scepter upgraded Last Word help Silencer deal with Terrorblade's illusions from Conjure Image and Manta Style.
* With Last Word Mutes talent, Silencer can not only disable Terrorblade from turning tables with Sunder, but can also prevent him from using Manta Style and Black King Bar, items Terrorblade needs to be effective in teamfights.
* Glaives of Wisdom deals magical damage against the real Terrorblade, bypassing his high base armor. Later it can be upgraded with 2 Glaives of Wisdom Bounces talent to deal against Terrorblade's illusions. Alternatively, Silencer is a natural 
Revenant's Brooch wielder, which gives him another way to damaging Terrorblade through his high base armor.
* Global Silence can silence Terrorblade even if he has Black King Bar active, though bear in mind that Terrorblade can dispel Global Silence with Manta Style and Black King Bar if the Global Silence was activated first.
Silencer
* Last Word and Arcane Curse have the range to hit Dark Willow beyond Bramble Maze.
* Global Silence renders Dark Willow useless in teamfights.
Silencer
* Kunkka relies on his powerful AOE spells to turn the tides of teamfights. He cannot use them while silenced.
* Last Word can mess up Kunkka's ability synergy, silencing him in the middle of his strong combo.
* Global Silence can disable Kunkka's spell casting from anywhere on the map, even if Kunkka is spell immune at the time.
Silencer
* Zeus' main source of damage is his low cooldown, high damage spells - meaning Last Word and Global Silence will pretty much take him out of the game for the duration.
* Zeus likes to spam his abilities, which makes him vulnerable to Arcane Curse.
* If Zeus dies near Silencer, he will begin to lose intelligence, reducing his mana pool, mana regen, and attack damage. Furthermore, if the game is long and Zeus dies often, the intelligence losses will also reduce his spell damage.
Additional:
* Silencer's Global Silence will render Zeus useless for 6 seconds in a team fight.
* Arcane Curse will punish Zeus for casting spells, which can cause continuous damage to him should he continue to cast spells.
* Last Word can silence Zeus and prevent him from spamming his spells.
* Silencer often builds 
Orchid Malevolence (or 
Bloodthorn) which can be used on spell casters like Zeus, forcing him to invest in a 
Linken's Sphere.
Lone Druid
* Alchemist likes to farm fast and be ahead, unfortunately Lone Druid likes to do the same by taking towers.
* 
Acid Spray will never prove a threat to Lone Druid or his Spirit Bear.
* 
Chemical Rage may not prove so useful once Lone Druid procs entangled keeping him in place.
* 
Monkey King Bar is a very good choice on Lone Druid's Spirit Bear and it directly counters any potential Radiance from Alchemist.
* 
Assault Cuirass is another very good Spirit Bear item that further makes Alchemist vulnerable to physical damage, which is all Lone Druid does.
* Alchemist is not the kind of hero who wants to go on single target summon units, by the time he has killed the Spirit Bear his teammates might had already been slayed by his teammates. Not to mention Lone Druid can just resummon it, even if he is successful.
Silencer
* 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.
Silencer
* Global Silence takes Omniknight out of the fight completely.
* Glaives of Wisdom are a great harass vs Omniknight during the laning stages of the game, since it doesn't aggro creeps & ignores his high base armor. It deals pure damage, which means it can also go through Guardian Angel.
* Silencer's intelligence steal can also cause Omniknight to falter in the early phases as it reduces his ability to use his spells.
Silencer
* Arcane Curse can be cast from a long range to put Enigma's Blink Dagger on cooldown.
* Global Silence can interrupt Enigma's Black Hole channeling through Black King Bar and Linken's Sphere, making Silencer one of Enigma's hard counters. But bear in mind that Global Silence can be dispelled with Black King Bar if activated first.
Additional:
* Silencer can easily ruin Enigma's initiation, as Global Silence cancels 
Black Hole, even through Black King Bar and Linken's Sphere.
Silencer
* Silencer burns easily through her effective HP from 
Mana Shield, by taking away her intelligence.
* Arcane Curse punishes her repeatedly casting 
Mystic Snake to keep her mana pool high. He can force her to use Manta Style before he has cast Global Silence and 
Medusa usually does not want to build Black King Bar.
Silencer
* Arcane Curse can effectively discourage Undying from casting his spammable abilities in a team fight, as Undying will have to suffer more damage and the slow due to the penalty duration of Arcane Curse.
* Last Word and Global Silence are able to silence Undying for up to 6 seconds, preventing Undying from gaining strength and healing his ally or himself.
Lone Druid
* Savage Roar interrupts 
Starbreaker.
* Dawnbreaker is a slow moving hero. Although tanky, Lone Druid can eventually wear her down with his better movement speed.
Lone Druid
* 
Omnislash spreads on both the bear and the druid, allowing them to survive.With enough levels,the bear can soak the ability alone and possibly dragging him to a dangerous location.
* Juggernaut cannot manfight the duo in the early game,because of their tankiness. If opposed in lane,Lone Druid can shut him down.
Lone Druid
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, 
Void Spirit, 
Mars.
Lone Druid
* Heroes who can fight back easily are not ideal matchups for Sven, such as Troll Warlord as mentioned above, Lone Druid and Templar Assassin.
Silencer
* Silences and other types of lockdown that prevent Weaver from using his spells: Silencer, Riki, Lion, Legion Commander, Shadow Shaman, Bane.
Lone Druid
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, Void Spirit, Mars.
Silencer
* Lion is extremely dependent on his abilities. Silences like Silencer's Last Word, magic resistance like 
Oracle's 
Fate's Edict, and dispels like Legion Commander's 
Press the Attack all make his abilities less effective.
Silencer
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, Silencer, Shadow Shaman, 
Grimstroke, 
Witch Doctor, Riki, 
Faceless Void, Skywrath Mage, Puck.
Silencer
* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.
Silencer
* Heroes with silences : Bloodseeker, Riki, Silencer.
Silencer
* Heroes with low mana pools (eg.Doom andTidehunter) will feel the effects of Silencer's Intelligence Steal far more than others.
Silencer
* Silencer's Global Silence and Doom's Doom makes Earthshaker temporarily useless.
Silencer
* Heroes that have long silences, such as 
Night Stalker and Silencer, will prevent Abaddon from saving his allies effectively and disable the active component of Borrowed Time.
Lone Druid
* 
Timbersaw: Lone Druid will have a hard time dealing with Timbersaw due to his tankiness and high Armor from 
Reactive Armor
Silencer
* Timbersaw is heavily reliant on his abilities for damage and escape, allowing Silencer to effectively disable him and make him useless in both team fights and 1v1 scenarios.
Additional:
* Arcane Curse deals repeated stacks of damage to Timbersaw because he relies on constantly using his abilities.
* Glaives of Wisdom deals pure damage and when cast manually, nearby creeps will not attack silencer, making it an effective harassment tool. The intelligence steal is also especially potent against Timbersaw since he often uses up all of his mana throughout the entire game.
* Although Last Word takes a while to trigger, it will break Timbersaw's ability combo and can be used to silence him.
* Global Silence will silence Timbersaw no matter where he is on the map. This can be used to help allies get a kill on him, or prevent Timbersaw from killing someone.
Lone Druid
* Heroes that have doubles or clones such as Arc Warden, Meepo or Lone Druid are vulnerable to Muerta's 
Gunslinger.
Silencer
* Silencer can reduce Muerta's damage output with his Glaives of Wisdom, and since he commonly buys Revenant's Brooch, he will be able to attack her even through 
Pierce the Veil.
* Silencer has reliable, long-range silences in Last Word and Global Silence, preventing Muerta from using her spells as effectively.
* As Muerta tends to use her spells, particularly 
Dead Shot; Arcane Curse is very effective against her as that can punish her for doing so.
Silencer
* Ranged heroes will have a hard time hitting enemies inside Magnetic Field: Silencer, Viper.
Lone Druid
* Because of his weak laning phase, Lone Druid absolutely overpowers him in the early to mid game. Lone Druid also directly counters most of his abilities.
* 
Flux is nullified when the Spirit Bear is nearby.
* 
Spark Wraith can get soaked by the bear.
* Lone Druid can easily go inside 
Magnetic Field and punish Zet.
Lone Druid
* 
Pugna: 
Decrepify prevent the Spirit bear from attacking or protect allies from it.
Silencer
* Pugna is very reliant on his abilities for damage which Silencer can take advantage off. But he has to be careful around the 
Nether Ward as Silencer's abilities cost a lot of mana to use.
Lone Druid
* 
Mystic Flare can be used to effectively ignore the Spirit Bear entirely and burst Lone Druid during the early mid game.
* 
Concussive Shot and 
Arcane Bolt will provide vision of Lone Druid allowing for better chase in teamfights before the Spirit Bear can do too much damage.
* 
Ancient Seal denies the ability to transform into True Form and receive bonus HP from the skill.
Silencer
* Heroes with silence such as Riki, Silencer, or Night Stalker prevents Skywrath Mage from using his spells.
Lone Druid
* Skywrath Mage also has a terrible time fighting against anything that isn't a hero. His skills are mostly target-based and he has terrible strength and agility, he can easily be kited or harassed by illusion-based heroes like Chaos Knight and 
Phantom Lancer, or by Heroes that summon other units like Lone Druid, 
Lycan and 
Beastmaster.
Lone Druid
* Morphling can ignore Spirit Bear and shorten the distance to Lone Druid with Waveform.
* Morphling can use his nukes to burst Lone Druid down, provided he is not rooted/disabled by Spirit Bear beforehand.
Silencer
* 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.
Lone Druid
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: Templar Assassin, Phantom Assassin, Ember Spirit, Morphling.
Lone Druid
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include 
Spectre, 
Shadow Demon, Phantom Lancer, 
Naga Siren, Chaos Knight, 
Terrorblade) or bring other units into the fight (such as 
Nature's Prophet, Lone Druid, 
Chen, 
Enchantress, Meepo and Arc Warden).
Lone Druid
* Heroes that create illusions: Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, Chen, Enchantress, Meepo and Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Lone Druid
* 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
Silencer
* 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.
Lone Druid
* 
Ghost Shroud can be use both offensively to slow Lone Druid or Defensively to prevent Lone Druid and The Spirit Bear from attacking him.
* 
Heartstopper aura burns the Spirit bear High HP over time. Additionally, it can deal decent damage to Lone Druid during his True Form.
Silencer
* Arcane Curse punishes Necrophos if tries to spam Death Pulse, increasing the duration of the slow and damage taken over time.
* Last Word heavily damages Necrophos and also silence him for a lenghty duration.
* Glaives of Wisdom will reduce temporarily Necrophos intelligence on each hit dealing hindering his ability to spam Death Pulse, also reducing his attack damage and mana pool; dealing increasing amounts of phisical and pure damage each time. Silencer will permanently steal Necrophos intelligence if Necrophos is killed by him or if he dies nears him.
* Global Silence turns Necrophos almost useless for a long time, allowing Silencer and his team to easily dispatch him, since Necrohpos heavily relies on his spells to survive.
Lone Druid
* Paralyzing Cask is likely to bounce between him and his bear every single time.
* Lone Druid's lack of mobility makes him vulnerable to Death Ward and Maledict.
Silencer
* Like any hero with a channeled spell, Last Word is a counter to it.
* Global Silence goes through spell immunity and prevents Witch Doctor from casting his spells.
Lone Druid
* Lone druid's bear attacks on Phoenix's 
Supernova Egg don't increase the hit count. Given that Lone Druid's main hero often doesn't have much farm, the Supernova Egg is less likely to get killed.
Silencer
* Silencer will most likely disrupt an initiation with his ultimate, Global Silence, prevent escape with his Last Word, and if Phoenix happens to die to him (or near him) enough times, he would sap enough of Phoenix's much needed Intelligence to make him a stronger foe and Phoenix with less mana than it already had.
Silencer
* 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
Lone Druid
* Heroes who just want to farm and avoid Lone Druid early will find it very hard to do so when he starts knocking on towers: Templar Assassin, Phantom Assassin, Ember Spirit, Morphling.
Lone Druid
* 
Laser blinds Lone Druid, making his attacks miss.
Silencer
* Silencer can stop 
Rearm, preventing Tinker from spamming his abilities/items or escaping.
* Tinker heavily relies on his mana pool and has mana issues throughout the entire game and Silencer's intelligence steal does not help with that.
Additional:
* As Tinker relies heavily on his spells to be effective, Last Word and Global Silence will render him largely useless.
* Arcane Curse effectively prevents Tinker from casting spells during its duration, as he will otherwise suffer heavy damage.
* Glaives of Wisdom deal pure damage, which make quick work of fragile heroes like Tinker.
* Silencer's intelligence steal permanently weakens Tinker since he's a hero who requires lots of mana to be effective.
Lone Druid
* Dazzle easily breaks the position of Lone Druid and his Summon Spirit Bear with his 
Poison Touch, As it always hits from afar and prolongs the slowdown on the Summon Spirit Bear, which is why he cannot catch up with Dazzle and treat his master with Spirit Link
* Dazzle helps his team survive the physical attacks of the Summon Spirit Bear thanks to the treatment from 
Shadow Wave and armor from 
Bad Juju, which can enable his team to kill Lone Druid
* The Lone Druid Summon Spirit Bear has a small amount of armor at the start of the game, because of Mid Dazzle, it can very much break through it and prevent Lone Druid from gaining an advantage at the very beginning of the game, giving his team the opportunity to overtake Lone Druid on items for killing him, by type: 
Spirit Vessel
Additional:
* Dazzle easily breaks the position of Lone Druid and his Summon Spirit Bear with his Poison Touch, As it always hits from afar and prolongs the slowdown on the Summon Spirit Bear, which is why he cannot catch up with Dazzle and treat his master with Spirit Link
* Dazzle helps his team survive the physical attacks of the Summon Spirit Bear thanks to the treatment from Shadow Wave and armor from Bad Juju, which can enable his team to kill Lone Druid

Silencer
* A well-timed Global Silence prevents Dazzle from saving allies with Shallow Grave or Shadow Wave. Items that could dispel the silence are expensive, and difficult for Dazzle to farm from a support role.
* Arcane Curse and Last Word cause long damage over time, which may outlast Shallow Grave.
Lone Druid
* 
Arcane Orb deals heavy damage to both Lone Druid and the Spirit Bear.
* 
Astral Imprisonment can prevent the Spirit Bear from attacking, which is Lone Druid's main damage output.
* 
Sanity's Eclipse deals heavy damage to Lone Druid.
Silencer
* Silencer's Intelligence Steal will heavily reduce Outworld Destroyer's damage output, particularly from Sanity's Eclipse.
* Last Word and Global Silence will take Outworld Destroyer out of the fight unless he has built Black King Bar.
Additional:
* Silencer's intelligence steal will heavily reduce Outworld Destroyer's damage output, especially if Destroyer dies a lot near Silencer and loses intelligence permanently.
* Global Silence and Last Word will render Outworld Destroyer helpless unless he has an item/ally to dispel silence.
Silencer
* Fortune's End can nullify Arcane Curse, Last Word, and Global Silence, if cast at the right time with the right targets.
* Fate's Edict can prevent Silencer from attacking, which he relies on with Glaives of Wisdom, for a lot of his damage.
Silencer
* Oracle's reliance on spamming his spells can be easily hindered by Silencer's Arcane Curse.
* Last Word and Global Silence negates Oracle's attempt to save his allies with his spells.
* Fate's Edict is useless against Glaives of Wisdom's pure damage.
Silencer
* Due to
Phantom Rush and 
Juxtapose being passives and not affected by silence, a Phantom Lancer with a 
Diffusal Blade can easily kill Silencer.
Lone Druid
* Lone Druid and his Spirit Bear lack mobility, and are easy overwhelmed after being slowed by
Diffusal Blade.
Savage Roar is useless since Phantom Lancer can return to fight him again with his 
Phantom Rush.
