Slardar
* 
Bloodseeker's 
Rupture forces Slardar to stay still during fights, preventing Slardar from using Guardian sprint to move in and out of fights. This takes away the ability to initiate and re-initiate with Slithereen Crush's low cooldown. Due to the increased move speed from Guardian Sprint, Slardar can lose health at about 160% the rate of normal heroes while under Rupture. Bloodseeker's 
Thirst also gives him enough move speed so that he's one of the few heroes who can outrun or catch up to a Slardar during Guardian Sprint.
Weaver
* 
Shukuchi will trigger extra damage from Rupture.
* Shukuchi's invisibility is detected by Thirst.
* 
Time Lapse cannot dispel Rupture, preventing Weaver from escaping ganks. However, smart Weaver will buy 
Linken's Sphere to counter this problem for him.
Additional:
* Rupture is particularly crippling against Weaver, who relies on high movement speed from Shukuchi to fight and escape, and it cannot be dispelled by Time Lapse.
* Thirst detects Weaver through Shukuchi whenever his health is low.
* 
Blood Rite combined with Rupture forces Weaver to either take damage from the latter, or to get silenced for a long duration.
Slardar
* Abaddon can cast 
Aphotic Shield on any of his allies to immediately dispel Corrosive Haze and/or the stun and the slow components of Slithereen Crush.
* All of Slardar's debuffs are also removed if Abaddon's 
Borrowed Time triggers.
Slardar
* 
Fortune's End applies a basic dispel which can be used to dispel Corrosive Haze, or even Slardar's own Guardian Sprint.
* 
False Promise is able to dispel Corrosive Haze and Slithereen Crush stun/slow from any allies Oracle chooses to cast it on.
* 
Fate's Edict can also be cast on Slardar to prevent him from proccing his Bash of the Deep.
Weaver
* Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use Time Lapse. It can also catch Weaver in Shukuchi.
* Weaver's high attack speed, along with high attack damage from 
Geminate Attack, triggers Counter Helix continuously and the output damage would be returned by 
Blade Mail.
Additional:
* 
Berserker's Call is one of the best ways to lock down Weaver before he has a chance to use Time Lapse. It can also catch Weaver in Shukuchi.
* Due to his fast attack speed from Geminate Attack and items that give attack speed, 
Counter Helix will activate a lot, and the damage would be returned by Blade Mail, which hurts Weaver far more than it hurts Axe.
* 
Culling Blade can finish off Weaver's low health pool before he escapes with Shukuchi and Time Lapse.
* 
Battle Hunger is a good tool to pop Weaver's Linken's Sphere due to its low cooldown.
Weaver
* The long silence of 
Crippling Fear at night prevents Weaver from using his Shukuchi or Time Lapse.
* With 
Dark Ascension and 
Gem of True Sight, Night Stalker can easily find and probably kill Weaver.
* 
Hunter In the Night's attack speed bonus removes The Swarm's beetles very quickly.
Weaver
* Shadow Shaman's many disables can lock down Weaver. Even with Linken's Sphere, Weaver might not be able to escape should Shadow Shaman uses Shackles quickly enough following Hex.
* Mass Serpent Wards can make short work of Weaver once he is locked down.
Slardar
* Slardar does not do well against multiple targets, as his only way to damage multiple targets is Slithereen Crush.
* Meepo's 
Earthbind will root Slardar, making him unable to chase/escape for the time being. Also, 
Poof's low cooldown and high damage can burst Slardar down rather quickly.
Weaver
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: 
Earth Spirit, 
Ember Spirit, 
Storm Spirit, 
Nature's Prophet, 
Phantom Assassin, 
Riki, 
Anti-Mage, 
Weaver.
* See items and abilities disabled by roots
Slardar
* Heroes who can stun multiple units at once: 
Dark Willow, 
Spirit Breaker, 
Slardar, 
Invoker, and 
Tidehunter.
Weaver
* A well-timed Fireblast with Multicast can prevent Weaver from escaping with Shukuchi and even Time Lapse.
* Ignite's high damage early on applies heavy pressure onto Weaver's very small health pool.
* However, the slow from Ignite is generally useless against Shukuchi, and Time Lapse dispels it if needed.
Slardar
* 
Fire Spirits greatly reduces Slardar's already low starting attack speed (which Bash of the Deep relies on), making the laning phase very hard for him and discouraging Slardar from aggressively threatening lane kills.
* 
Supernova, ignoring Phoenix's lack of armor and Slardar's high damage single hits, is extremely hard for Slardar to take down on his own, especially after being hit by Fire Spirits.
* 
Icarus Dive is one of the longest distance escape spells in the game, and can help a good Phoenix escape from Slardar before he gets a 
Blink Dagger. However, the high cooldown means Phoenix is vulnerable to backstabs from any roamers after said spell is used.
* Slardar can interrupt an Icarus Dive from completing the flight with both of his stuns, however, likely leading to death if Supernova is on cooldown.
* A lot of the items a Phoenix builds throughout the game naturally counter Slardar. 
Shiva's Guard, 
Heaven's Halberd and 
Eul's Scepter of Divinity all stall Slardar's normal attacks in some way, while 
Spirit Vessel's percentage-based damage is good against his innate durability.
Weaver
* 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.
Weaver
* Time Dilation while Shukuchi and Geminate Attack are on cooldown will make these abilities unusable for a long time, reducing Weaver's escape potential.
* Chronosphere will reveal Weaver during Shukuchi.
Additional:
* The wide range of 
Chronosphere makes it difficult for Weaver to avoid it with Shukuchi and, once caught, his low survivability makes him an easy kill.
* With no significant source of burst damage, it is easy for Void to survive combat with Weaver using 
Time Walk.
* 
Time Dilation will prevent Weaver from using Shukuchi or force him to use Time Lapse to dispel the debuff and re-engage.
Weaver
* 
Ball Lightning allows Storm Spirit to close the gap between him and Weaver in no time. Once locked down with certain items, Weaver is extremely fragile to Storm Spirit and his teammates.
Weaver
* Weaver's exceptional ability to elude and survive through clashes and ganks is hard countered by 
Lion in every aspect.
* Weaver is very mana dependent and has a rather small mana pool in the beginning of the game, of which 
Mana Drain can deplete and lessen his early game presence.
* 
Earth Spike followed by 
Finger of Death in the huge majority of the time is enough to kill Weaver.
* Earth Spike can be point targeted to hit through Shukuchi.
* 
Hex's has a fair long duration, by which Weaver will not be able to deal damage, or even survive a coordinated attack, and it is single target, of which cannot be dodged.
* Mana Drain easily breaks Linken's Sphere. Its low cooldown allows Lion to infinitely break it whenever it recharges.
* Earth Spike and Hex when paired for the longer lengths of disables may diminish Time Lapse efficiency, possibly causing Weaver to not undo as much damage as he would.
Weaver
* Shukuchi cannot help Weaver escape from Arena of Blood, and can most likely die if detected through invisibility.
* If pinned to the arena's walls, Time Lapse tends to not be enough to save Weaver, as God's Rebuke can keep him burst down thanks to its damage scaling.
* 
The Swarm and Geminate Attack are not enough to pierce through Bulwark.
Weaver
* Phantom's Embrace and Soulbind prevent Weaver from using Shukuchi or Time Lapse to escape.
* Ink Swell discourages Weaver from moving through and damaging allies with Shukuchi.
Slardar
* Phantom Lancer's 
Doppelganger has a low cooldown and applies a basic dispel on PL, making it hard to keep Corrosive Haze on him.
* Phantom Lancer usually purchases 
Manta Style which provides another basic dispel to remove Corrosive Haze with.
* Besides Slithereen Crush, Slardar does not have another way to deal with illusions and has a low mana pool, which allows Phantom Lancer with 
Diffusal Blade to quickly build up illusions while draining Slardar's mana.
* 
Phantom Rush outruns Guardian Sprint, forcing Slardar to Blink away or use Slithereen Crush defensively to avoid being killed.
Weaver
* Earthshaker's many stuns can lock down slippery heroes like 
Slark in his 
Shadow Dance and Weaver in his Shukuchi.
Weaver
* Even though Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, 
Queen of Pain, 
Morphling, 
Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.
Additional:
* 
Arcane Bolt has a long range and a low cooldown, and is a great spell to waste Linken's Sphere. It also serves as an effective spell to harass Weaver with.
* 
Ancient Seal prevents Weaver from using Shukuchi or Time Lapse.
Slardar
* Illusion heroes like the aforementioned 
Phantom Lancer or 
Naga Siren, or heroes that tend to buy Manta Style, like 
Luna or 
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
Slardar
* Tidehunter's 
Kraken Shell dispels Corrosive Haze and Bash of the Deep's stun if enough damage is taken. 
Anchor Smash and Kraken Shell's damage block also reduces Slardar's damage.
Weaver
* Silences and other types of lockdown that prevent Weaver from using his spells: 
Silencer, Riki, Lion, 
Legion Commander, 
Shadow Shaman, 
Bane.
Slardar
* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
Weaver
* Techies is very good against roaming supports and gankers such as 
Bounty Hunter, Riki, Weaver, 
Earthshaker, 
Nyx Assassin, etc. that are constantly moving around the map.
Weaver
* Shukuchi vision can easily target Charge of Darkness before Weaver purchase Linken's Sphere.
Additional:
* Spirit Breaker's strong escape combo abilities from 
Charge of Darkness and 
Bulldoze can easily catch Shukuchi from Weaver.
* Time Lapse cannot dispel neither Charge of Darkness nor 
Nether Strike.
* However, Weaver is a common Linken's Sphere wielder. And if he has it, Spirit Breaker will not be able to catch up with Weaver neiter with Charge of Darkness nor with Nether Strike.
Weaver
* Heroes that usually build Linken's Sphere as either a core or situational item: Weaver, 
Medusa, Morphling, Queen of Pain, Storm Spirit, Luna, Naga Siren.
Weaver
* Weaver has poor health, relying on Shukuchi and Time Lapse to survive, With Jakiro's considerable arsenal of stuns, Weaver cannot initiate on Jakiro without being punished heavily or even killed in return.
* While difficult, Ice Path can catch Weaver during Shukuchi, And since Shukuchi only lasts 4 seconds while Ice Path's stun lasts 3.5, the stun from Ice Path will strip him of his escape.
* Weaver has to be very careful casting Time Lapse around Jakiro, as it could very easily put him inside of a Macropyre or Ice Path.
Weaver
* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, Juggernaut, Phantom Assassin, Weaver.
Weaver
* Sprout with True Sight items (
Sentry Ward or 
Dust of Appearance) make it possible to trap Weaver in lane, unless he buys 
Quelling Blade or until he unlocks Time Lapse.
* The Swarm beetles can be destroyed with Nature's Prophet's Treants.
Slardar
* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying 
Shadow Blade: Bounty Hunter, Slardar, 
Spectre, 
Zeus, Spirit Breaker.
Slardar
* 
Guardian Sprint allows Slardar to outrun Bristleback, even when slowed by Viscous Nasal Goo.
* 
Corrosive Haze's armor reduction makes Bristleback much less tanky.
Weaver
* 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.
Slardar
* Slardar can use Guardian Sprint with Blink Dagger or Shadow Blade to get close, and 
Slithereen Crush will stun Sniper and slow him, making him vulnerable to Slardar's teammates.
* Corrosive Haze lowers Sniper's armor and makes Sniper's Shadow Blade useless, easily killing him with a few attacks.
Weaver
* Shukuchi allows Weaver to close the gap between himself and Sniper with high speed, and to maneuver through teamfights to get on top of him.
* A combination of The Swarm and 
Desolator tears through Sniper's low armor.
Slardar
* Corrosive Haze reveals Pudge's location, making it hard for him to use Meat Hook from the fog of war on Slardar's teammates or Slardar himself.
* Slithereen Crush interrupts Pudge while he is using Dismember.
* Guardian Sprint allows Slardar to avoid Meat Hook.
Additional:
* While Slardar has Guardian Sprint activated, 
Rot cannot slow him and 
Meat Hook is easier to avoid.
* Slithereen Crush allows Slardar to interrupt 
Dismember at close range (when Slardar is not a target).
* Corrosive Haze reveals Pudge's location, making it very difficult for him to land hooks from the fog.
Weaver
* Shukuchi grants Weaver invisibility and a high degree of mobility for a short time, which can make him a difficult target to hook.
* The Swarm beetles are difficult for Pudge to remove, due to his low base attack time and poor agility. Additionally, it can be used to can scout out Pudge's location.
* Should an ally get snagged by Meat Hook, Weaver can use 
Aghanim's Scepter upgraded Time Lapse on them to send them back to where they were before hooked, even if Pudge has already started to Dismember them.
Additional:
* While Weaver is in Shukuchi, Rot doesn't slow him and Meat Hook is easy to avoid.
* Even when hooked, Weaver can use Time Lapse, negating both the damage and displacement.
* Pudge has low armor and low attack speed, making him susceptible to The Swarm and physical attacks.
* Dismember is easy to block with Linken's Sphere and it's the only way to break Weaver's Linken Sphere.
* However, the long duration stun of Dismember can be dangerous for Weaver.
Slardar
* Slardar is one of the few meele heroes who can lane against Ursa in the early game, out harassing him with Bash of the Deep, and running away from a bad engagement with Guardian Sprint
* Corrosize Haze can force Ursa to cast 
Enrage defensively instead of offensively
* With Corrosize Haze, Slardar's team can quickly dispatch of Roshan, denying one of Ursa's greatest advantages
Weaver
* The swarm beetle can waste Ursa's 
Overpower attacks.
* Ursa has no inherent way of disabling a slippery Weaver by preventing him from Shukuchiing or Time Lapseing away, as the slow from Earthshock is useless against Shukuchi's haste effect.
Additional:
* 
Earthshock's slow is ignored by Shukuchi.
* Ursa can be kited with Shukuchi and his burst damage will be negated with Time Lapse as long as Weaver survives it.
* The Swarm breaks Ursa's Blink Dagger, forcing him to deal with the beetles.
Slardar
* Slardar deals entirely physical damage. He does not have to worry about Counterspell.
* Slithereen Crush and 
Bash of the Deep prevent Anti-Mage from using Blink, the latter even if Anti-Mage activates 
Black King Bar.
* Corrosive Haze allows allies to take down Anti-Mage before he has a chance to Blink, and maintains vision over him even if he does Blink away.
Additional:
* Slithereen Crush and Bash of the Deep deals physical damage, bypassing the magic resistance bonus from 
Counterspell
* Corrosize Haze significantly increases the damage dealt against Anti-Mage, and makes it harder for him to flee with 
Blink, although Anti-mage can block its casting with with Counterspell
Weaver
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, 
Arc Warden, 
Dark Seer.
Slardar
* Shadow Fiend, a normal Shadow Blade builder often relies on its invisibility to escape fights. Corrosive Haze reveals Shadow Fiend and also weakens his already low armor.
Weaver
* Heroes that are hard to kill without lockdown: 
Puck, Weaver.
Slardar
* Heroes with high physical damage can damage Lifestealer more than he can heal: 
Bristleback, Clinkz, Luna,
Shadow Fiend, Slardar, 
Terrorblade
Weaver
* Though The Swarm can be blocked by Rage, it can be used to lower Lifestealer's already low armor, making him even more vulnerable to physical damage while Rage is on cooldown.
* Lifestealer has no strong disables on his own and thus cannot catch up with nor escape from Weaver's Shukuchi.
* Lifestealer's reliance on meticulous auto-attacks will not help against Time Lapse, which can undo Lifestealer's already slow build-up of damage. Aghanim's Scepter upgraded Time Lapse can also be used to save allies from getting killed by Lifestealer, but that will require targeting the allied hero rather than just pressing the button that will trigger the Time Lapse.
Additional:
* 
Open Wounds's slow is ignored by Shukuchi.
* Lifestealer has no other lockdown and relies on being on top of enemies; Weaver can kite him with ease.
Slardar
* Slardar's Slithereen Crush allows him to stun Spectre and illusions, and Corrosive Haze prevents her from juking with 
Spectral Dagger.
Weaver
* Heroes with good escapes can usually outmaneuver and escape from Spectre: Slark, Clinkz, Weaver
Weaver
* Time Lapse with Aghanim's Scepter dispels Flaming Lasso when used on allied hero.
* Linken's Sphere is core item for a Weaver making him a hard target for Lasso during entire game.
Weaver
* Weaver can easily kill Chen's creeps and kite Chen with The Swarm and Shukuchi.
* Neither Chen nor his converted creeps have burst damage at all, so Weaver will always have plenty of time to save himself with Time Lapse or his allies with Aghanim's Scepter upgraded Time Lapse.
Weaver
* Shukuchi allows Weaver to have faster movement speed and can outrun Primal Beast in most instances, such as while he is trampling.
* Trample disarms Primal Beast, so casting The Swarm can make him vulnerable to ranged attacks. Primal Beast also has an innately slow attack speed and will take a long time destroying the bugs.
* Time Lapse allows Weaver to negate and heal burst damage, which Primal Beast is reliant on.
Weaver
* Shukuchi can break Static Link with little trouble.
* Time Lapse can easily be used to avoid damage from Plasma Field and can recover the damage done from Static Link and Eye of the Storm.
* Eye of the Storm can't kill bugs from The Swarm.
Weaver
* Brewmaster is slow and has low armor, making his laning stage very difficult against Geminate Attack.
* Apart from the slow moving 
Hurl Boulder, which can be disjointed, he has no control to catch Weaver.
Weaver
* Time Lapse allows Weaver (or an ally if upgraded with Aghanim's Scepter) to regain HP while affected by Ice Blast.
* Shukuchi completely ignores the slow from Ice Vortex and helps him escape the freeze range of Cold Feet.
Additional:
* 
Cold Feet is extremely easy to nullify with Shukuchi.
* 
Ice Vortex does not slow Weaver in Shukuchi.
* Time Lapse will still affect his health, even when hit by 
Ice Blast.
* Ancient Apparition has no escapes or saves and is very squishy, making him an easy target for Weaver to get on top of.
Slardar
* The brutal physical damage of Slithereen Crush and Bash of the Deep can quickly remove Void Spirit's shield and stun him for a while.
* Corrosive Haze provides vision of Void Spirit while he is running away and Guardian Sprint allows Slardar to quickly close the gap
Slardar
* While Slardar has Guardian's Sprint activated, 
Powershot cannot slow him and is easier to avoid.
* Slithereen Crush and Bash of the Deep help Slardar put Windranger in place, even when she uses 
Windrun to escape.
* Corrosive Haze from Slardar is very effective against Windranger's already low armor. This becomes even worse if she has Aghanim's Scepter-upgraded Windrun, because it also reveals her position and allowing his allies to use their abilities on Windranger.
* Note that the invisibility provided by Aghanim's Scepter-upgraded Windrun is not broken upon attacking, casting abilities or using items, so it's vital to cast Corrosive Haze beforehand.
Slardar
* Corrosive Haze followed by Slithereen Crush takes advantage of Alchemist's main weakness, being physical damage before he has the change to improve his surviability with items.
* Bash of the Deep will deal lots of damage during the laning phase.
Weaver
* Shukuchi ignores slows and allows Weaver to escape Viper's onslaught.
* Time Lapse dispels 
Poison Attack and 
Corrosive Skin and undoes poison damage.
* Weaver's high burst damage allows him to kill Viper before being killed.
Weaver
* Weaver's Shukuchi allows him to escape from Warlock's Upheaval with high move speed.
* Time Lapse allows Weaver to ignore damage from Warlock's Golem and escape.
Weaver
* Marci's Dispose is blocked by Linken's Sphere which is a common item for Weaver.
* Shukuchi allows Weaver to escape from 
Rebound slow.
* The swarm beetle require 4 hits to kill. Weaver can use it on her when she use Unleash. This give Marci a hard choice: ignore The swarm and her armor keep decreasing or kill the beetle and wasting 4 attacks of Unleash.
Slardar
* Slardar can reveal Clinkz with Corrosive Haze and make him easy to kill, and his Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on 
Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.
Weaver
* Geminate Attack works on 
Tombstone, allowing Weaver to kill it quickly.
* Zombies attacking Weaver disappear once he goes invisible with Shukuchi.
* Undying has no way to catch a mobile Weaver.
Weaver
* Weaver doesn't care much about Lich's slows thanks to Shukuchi.
* If he sees Chain Frost is targeting him, he can easily isolate himself with Shukuchi so that it stops bouncing around.
* Unless Lich bursts Weaver immediately, Lich has no hard disables or silences to prevent him from using Time Lapse.
Weaver
* Bounty Hunter has a cheap way to break Linken's Sphere and keep track of Weaver while he is using Shukuchi, though both can be dispelled with Time Lapse.
Slardar
* Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
Additional:
* Bounty Hunter's 
Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
Weaver
* Weaver with Time Lapse
* Heroes that can remove the Track debuff with their skills:
* 
Abaddon with Aphotic Shield and Borrowed Time
* 
Huskar with 
Life Break
* Juggernaut with 
Blade Fury
* Legion Commander with 
Press the Attack
* 
Lifestealer with 
Rage and 
Infest
* Naga Siren with 
Mirror Image
* 
Omniknight with 
Heavenly Grace
* 
Oracle with Fortune's End and False Promise
* Phantom Lancer with Doppelganger
* Slark with 
Dark Pact
* 
Ursa with Enrage
* Weaver with Time Lapse
* Tidehunter with Kraken Shell when damage received reaches the threshold.
Weaver
* Sven can be easily kited since Weaver is a natural Linken's Sphere carrier and Sven relies on 
Storm Hammer to disable and kill a hero.
Weaver
* 
Wraithfire Blast is easy to disjoint with Shukuchi or Time Lapse, and it's the only way to break Weaver's Linken Sphere.
* Wraith King has no other disables and no mobility, allowing Weaver to chase or escape Wraith King as he wishes.
* With the Mana Break talent and Diffusal Blade, Weaver can prevent 
Reincarnation from triggering until Wraith King gets his shard.
Additional:
* Weaver can run away after killing Wraith King once thanks to Shukuchi.
* Wraithfire Blast is quite predictable. If Weaver is quick, he will disjoint it with Shukuchi and proceed to chase Wraith King down.
* Shukuchi does have a fade time. They cannot disjoint it if you use it right next to them. They will be stunned and take damage; however they will still become invisible if they used Shukuchi before the stun hits.
* Weaver can easily harass Wraith King out of his lane thanks to his high base damage and Geminate Attack.
* Weaver can burn Wraith King's mana quickly with his {ValueColor:1|Mana Break|15tal} {Symbol:Talent} talent or Diffusal Blade, until Wraith King purchases Aghanim's Shard to remove Reincarnation's manacost.
Slardar
* Corrosive Haze will reveal Treant Protector even when he is under the effects of Nature's Guise.
Weaver
* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.
Weaver
* Heroes who often build Linken's Sphere: Weaver, Morphling, Medusa.
Slardar
* Slardar can attack through Plague Wards and gain Bash of the Deep charges, and 
Templar Assassin can spill 
Psi Blades through Plague Wards too.
Weaver
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, 
Lycan, 
Centaur Warrunner.
Slardar
* Heroes with spells that negate invisibility such as Bounty Hunter, Zeus and Slardar prevent her from saving her allies with Moonlight Shadow.
Slardar
* Heroes who can provide True Sight are always credible threats: Slardar, Bounty Hunter, especially Zeus since his 
Lightning Bolt provides True Sight without the need to detect her beforehand to apply the debuff. So even a late-coming Zeus can easily scout a large area to reveal her, and she cannot purge herself from his sight with the dispel talent.
Slardar
* Bounty Hunter and Slardar both have ultimates (Corrosive Haze and 
Track) that reveal Invoker through Ghost Walk.
Weaver
* Any hero who can survive Magnus's initiations and manfight him: Huskar, 
Faceless Void, Weaver, Abaddon, 
Troll Warlord, 
Alchemist, 
Dragon Knight, 
Night Stalker, 
Viper.
Slardar
* Slardar can chase Dragon Knight down with Guardian Sprint and stun him with both Slithereen Crush and his passive Bash of the Deep. He can also use Corrosive Haze to whittle Dragon Knight's armor.
Weaver
* Weaver cannot Time Lapse out of Huskar's burn damage.
Slardar
* Corrosive Haze and Bash of the Deep will make short work of Huskar's low armor, even if Slardar is alone.
Weaver
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, 
Dazzle, Bristleback, 
Vengeful Spirit.
Weaver
* Heroes with one single-target abilities such as 
Wraith King, 
Necrophos, or 
Doom will struggle against Weaver's Linken Sphere.
Weaver
* In general, Timbersaw struggles against highly mobile heroes that can avoid his abilities: Puck, Weaver, Ember Spirit and others.
Slardar
* Slardar's level 25 talent makes Corrosive Haze undispellable, thus providing his allies vision of Slark.
Weaver
* Heroes who can dodge Earth Spirit's abilities: Ember Spirit, Puck, Weaver
Weaver
* You can potentially kill a fragile Weaver by using Disruption during Shukuchi with a well-placed Sentry Ward, wasting the Shukuchi. But odds are he'll wait to get low health, Time Lapse the damage away and Shukuchi away once more.
Weaver
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying 
Dagon and 
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: Faceless Void, Terrorblade, Ursa, Weaver, 
Broodmother, Slark, Abaddon, Wraith King, Lifestealer.
Weaver
* Dark Seer's only disable is Vacuum. Though he starts off with high armor and health, he'll eventually have a hard time dealing with high mobility heroes such as Weaver or Queen of Pain.
Slardar
* Heroes with armor reducing abilities greatly hinder Visage's defense like Slardar and Dazzle.
Weaver
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.
Weaver
* Heroes that rely on slows or low-duration stuns have trouble catching Weaver: Omniknight, 
Lich.
Slardar
* Terrorblade starts out with and gains a lot of armor from his agility growth. His illusions also make it difficult for Slardar to focus down the real Terrorblade.
Weaver
* Heroes whose core item builds includes 
Monkey King Bar: Faceless Void, 
Windranger, Weaver, Juggernaut.
Weaver
* Heroes that lack burst damage will have a difficult time taking down Monkey King, and fare badly against Jingu Mastery: Legion Commander, Lifestealer, Weaver, Wraith King
Weaver
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: Bloodseeker, 
Treant Protector with Eyes In The Forest, 
Sniper, Weaver
Weaver
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Slardar
* 
Crystal Maiden's already low armor and easily interruptible ultimate, 
Freezing Field can make Slardar her worst nightmare. Crystal Maiden also often builds 
Glimmer Cape which is revealed by Corrosive Haze.
Slardar
* Illusion heroes like the aforementioned Phantom Lancer or Naga Siren, or heroes that tend to buy Manta Style, like Luna or Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
Weaver
* Escape-type carries: Slark, Storm Spirit, Weaver.
Weaver
* Smoke Cloud prevents Shukuchi and Time Lapse, leaving Weaver helpless against Riki.
* The Swarm is ineffective against Riki because invisibility instantly removes the beetles.
Slardar
* Corrosive Haze works much like Track, giving the enemy team vision over Riki. While it doesn't give a movement speed or gold bonus, it instead can melt Riki's armor and Slardar can use Guardian Sprint to catch up to him.
* Slardar's 
Aghanim's Shard, causes Slithereen Crush to apply Corrosive Haze even if Slardar does not have vision over him.
Additional:
* Corrosive Haze makes Riki completely vulnerable to Slardar and his allies, as Riki has no easy way of dispelling it.
* Slardar's physical damage with Slithereen Crush and Bash of the Deep amplified by Corrosive Haze can easily kill Riki.
Weaver
* 
Spiked Carapace allows Nyx to get an easy long-duration stun on Weaver once he uses Shukuchi, and then he can follow up with 
Impale.
* 
Vendetta works as a great setup for both Impale and Spiked Carapace and can deal decent damage to Weaver. Additionally he can neutralize The Swarm beetles due to his invisibility duration.
Slardar
* Corrosive Haze hinders Nyx Assassin's ganking attempts with Vendetta, as well as reducing his armor and make him very vulnerable due to his low health pool.
* Guardian Sprint allows Slardar to catch up with Nyx Asssassin and finish him off if he has vision over him.
Weaver
* 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.
Weaver
* Heroes who commonly buy Linken's Sphere: Luna, Weaver, Morphling, Queen of Pain, Ember Spirit.
Slardar
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; Spirit Breaker, Legion Commander, 
Axe, Puck, and Slardar.
Weaver
* Enigma lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Enigma finishes his initiation: Faceless Void, Terrorblade, Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, Lifestealer.
Weaver
* Duel's long duration prevents Weaver from activating Time Lapse or escaping with Shukuchi.
Slardar
* With armor items like 
Solar Crest or 
Assault Cuirass combined with Bash of the Deep, Slardar can easily tank the 
Duel, If not dueled himself, he can drop Legion Commander's armor during duel and/or buff his teammate and save them, leaving her only the choice of dueling supports which can also be saved with fast Blink into Slithereen Crush.
Slardar
* Medusa cares less than other heroes about armor reduction, since 
Mana Shield blocks 70% of all damage without taking armor/magic resistance into consideration. This makes 60% of your Corrosive Haze ineffective until Medusa's mana is drained.
Slardar
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter, Bristleback, Slardar.
Slardar
* Slardar has high priority on building moblity items such as
Blink Dagger rather than tank items. Zeus can easily deal large amount of damage to him if not caught out of position first.
Weaver
*
Arc Lightning has a low cooldown can used to pop his 
Linken's Sphere.
Lightning Bolt or (
Nimbus upgraded from 
Aghanim's Scepter) detects Weaver during Shukuchi, preventing his ganks.
Thundergod's Wrath can kill Weaver quickly before he can cast his Time Lapse at low health.
