* 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.

* Morphling can Attribute Shift to strength after being hit by Maledict. Since Maledict deals its damage based on the difference between HP on cast and HP after two seconds, odds are Morphling will have more HP than when Maledict was cast, thus resulting in no damage.
* On the upside, players prone to panicked reactions may Morph to agility, making Maledict even more efficient than intended.
* Adaptive Strike (Strength) can interrupt Death Ward at a decent range.

* Heroes with mobility spells can quickly escape from Stroke of Fate or break out of Soulbind: Anti-Mage, Queen of Pain, Morphling, Storm Spirit

* Arcane Curse punishes Grimstroke for spamming Stroke of Fate.
* Global Silence takes Grimstroke out of team fights entirely.

* By using Morph, Morphling can use Windrun and Shackleshot to counter Windranger herself.
* Waveform can allow Morphling to easily chase down Windranger.
* Windranger's low health also makes her vulnerable Morphling's magical nukes, especially the Ethereal Blade and Adaptive Strike combo.

* 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.

Additional:
* Silencer's abilities hamper Windranger's effectiveness in battle, preventing her from comboing abilities and escaping using Windrun.

* Waveform allows Morphling to escape from Mass Serpent Ward
* Morphling can interrupt Shadow Shaman while he is shackling an ally with Adaptive Strike (Strength).
* With Ethereal Blade Morphling can quickly burst him down before he even has a chance to react.

* With 4 active abilities, Shadow Shaman is weak against silencing foes such as silencer, Drow Ranger and Death Prophet.

* 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 burns easily through her effective hp from Mana Shield, by taking away her int.
* Arcane Curse punishes her repeatedly casting Mystic Snake to keep her mana pool high. Can force her to use Manta Style before he has cast Global Silence and Medusa usually does not want to build Black King Bar.

* Global Silence stops Snapfire's Mortimer Kisses.
* Last Word can prevent Snapfire from casting additional spells.

* 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 abilitiess, he will begin to lose Warpath charges.

* 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.
Additional:
* 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 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.

* 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 laning stage as its cooldown is lower than Flame Guard's.

* 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.

* 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.

* 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.

* 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.
* 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 Timberaw 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.
Additional:
* 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.

* Lifestealer is a great target for Morphling to use Morph, as he can use Rage to gain spell immunity and a movement speed boost.
* Morphling's high armor also makes Lifestealer's attacks do less damage.

* 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 block Storm Spirit from connecting abilities after a Ball Lightning on his targets.

* 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.

* 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.

* Because Warlock's abilities are all active abilities, Silencer can make his impact minimal.
* Arcane Curse prevents Warlock from using his abilities without taking 56/84/112/140 damage, and slowed by 9%/12%/15%/18%.
* Last Word can prevent Warlock from casting his combo.
* Global Silence can nullify Warlock's impact in fights and prevent him from getting any spells off.

* 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.

* 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.

* Morphling can escape from Rupture using Waveform.
* Morphling is a typical Manta Style carrier, which can be used to dispel the silence from Blood Rite.
Additional:
* Waveform ignores Rupture's damage, letting Morphling escape unharmed.
* Attribute Shift (Strength Gain) makes it very hard for Bloodseeker to kill Morphling or gain his Thirst bonuses, since Morphling can use it to sustain damage while trading attacks when Ruptured.
* Morphling usually builds Linken's Sphere, which blocks Rupture.
* Morphling usually builds Ethereal Blade, which can be used to turn himself or an ally ethereal, and avoid Bloodseeker's attacks.

* 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.

* Waveform allows Morphling to easily escape Power Cogs.
* Clockwerk's lack of burst damage makes it nearly impossible for him to kill a Morphling using Attribute Shift (Strength Gain).
Additional:
* Morphling can escape from Power Cogs with Waveform.
* Even if Morphling is trapped in Power Cogs, Morphling can use Attribute Shift (Strength Gain) to survive the duration.
* However, Morphling should be wary of using his Ethereal Blade combo on a Clockwerk with Blade Mail.

* Last Word and Arcane Curse have the range to hit Dark Willow beyond Bramble Maze.
* Global Silence renders Dark Willow useless in teamfights.

* Pugna is very reliant on his abilities for damage. (Just be careful around the Nether Ward)

* By using Morph, Morphling can use Death Pact and Searing Arrows to counter Clinkz himself.
* Waveform can allow Morphling to easily chase down Clinkz.
* Clinkz's low health pool also makes him vulnerable to Morphling's magical nukes, especially his Ethereal Blade and Adaptive Strike combo.

* 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.
Additional:
* Silencer can stop Rearm, preventing Tinker from spamming his abilities/items or escaping.

* Morphling can break Static Link with Waveform. Alternatively, Morphling can Morph into Razor and use the same ability against him.
* Morphling's high armor makes Eye Of The Storm mostly ineffective, enabling Morphling to fight Razor for longer.
* Razor has no disables, enabling Morphling to avoid his abilities as needed.

* Silencer can easily ruin Enigma's initiation, as Global Silence cancels Black Hole, even through Black King Bar and Linken's Sphere.
Additional:
* Last Word can be cast from a long range to prevent Enigma's potential initiation.
* Global Silence can interrupt Enigma's Black Hole channeling through Black King Bar and Linken's Sphere.

* Heroes who often build Linken's Sphere: Weaver, Morphling, Medusa.

* Basically, Heroes that heavily rely on abilities for damage or escape, such as Queen of Pain and Storm Spirit.

* Silencer's Global Silence and Doom's Doom makes Earthshaker temporarily useless.

* Heroes with silences : Bloodseeker, Riki, Silencer.

* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit

* Heroes that usually builds Linken's Sphere as a core item: Weaver, Medusa, Morphling, Queen of Pain, Storm Spirit

* Silences and other types of lockdown that prevent Weaver from using his spells: Silencer, Riki, Lion, Legion Commander, Shadow Shaman, Bane.

* 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.

* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.

* Arcane Curse discourages Lina from using her abilities, preventing her from building up Fiery Soul stacks.
* 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.

* Morphling common combo Ethereal Blade and Adaptive Strike (Agility) can easily burst down Terroblade, bypassing his high armor.
* Morphling is likely to burst down Terrorblade due to his high armor, Attribute Shift.

* 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.

* 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 killed by him or dies nears him.
* Global Silence turns Necrophos almost useless for a long time, allowing your team to easily dispatch him, since he heavily relies on his spells to survive.

* Silencer's Last Word and Global Silence prevents Jakiro from casting any spell.
* A carry Silencer can easily take down a support Jakiro with his Glaives of Wisdom.

* Generally strong against every spellcaster, Puck fully relies on their skill set and is barely a threat when silenced.
* Arcane Curse disables Blink Dagger for quite some time, and is also effective against Puck as he tend to use his 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 his full combo off, limiting his effectiveness in team fights or ganks.
* Global Silence can take Puck out of fights entirely.

* Morphling's naturally high armor thanks to his high agility makes it hard for Phantom Assassin to take him down with Coup de Grace.
* Phantom Assassin is vulnerable to magical damage, falling easily to Adaptive Strike + Ethereal Blade combo.
Additional:
* Morphling's high armor serves as a direct counter to Phantom Assassin, causing her attacks to do far less damage. She is also very vulnerable to burst damage, and can be brought down quickly using his Ethereal Blade and Adaptive Strike combo.

* 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.

* While many of Silencer's spells are a great steal for Rubick, Silencer effectively neuters Rubick's excellent counter-initiation potential thanks to Global Silence.
* Rubick's relatively low intelligence for such a heavy caster means that losing Intelligence to Intelligence Steal will make your mana pool even smaller.

* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
* Sniper's low health also makes him extremely vulnerable to Morphling's Ethereal Blade and Adaptive Strike combo.

* 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.
