Weaver
* Weaver relies on 
Shukuchi to escape and kite enemy heroes. Slardar's Corrosive Haze lowers armor and reveals Weaver, who is already a very frail target.
* Weaver usually builds 
Linken's Sphere, Corrosive Haze can be used to pop the spell block, additionally the level 25 undispellable talent will prevent Weaver from removing Corrosive Haze with 
Time Lapse, allowing allied heroes to use their abilities on Weaver.
Additional:
* 
Corrosive Haze lowers armor and reveals Weaver during Shukuchi, who is already a frail target. In addition, Weaver usually builds Linken's Sphere, and Corrosive Haze can be used to "pop" the spell block. His level 25 talent can also make Corrosive Haze undispellable by Time Lapse, which puts Weaver in an even worse situation.
* 
Guardian Sprint can dodge Weaver's bugs with the movement speed bonus.
Dark Seer
* 
X Marks the Spot prevents Dark Seer or his allies from escaping with Surge.
Dark Seer
* 
Fortune's End dispels Ion Shell and Surge, making any gank attempt on Dark Seer in the laning phase likely to succeed.
* 
Fate's Edict prevents all magical damage that comes from Dark Seer's abilities.
* Fortune's End dispels Ion Shell on creeps, which Dark Seer relies on to farm and zone.
Additional:
* Fortune's End can dispel 
Ion Shell, a skill that helps Dark Seer immensely in the laning phase, as well as 
Surge, a move-speed buff, effectively allowing Oracle to control Dark Seer, especially in the laning phase.
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.
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.
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
* 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.
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.
Weaver
* 
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.
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
* 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
* 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
* 
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.
Dark Seer
* 
Spell Steal will easily steal all abilities from Dark Seer.
Additional:
* Spell Steal can perfect from Rubick's steal all abilities from Dark Seer. Rubick's always purchase 
Aghanim's Scepter can two stolens abilities from Dark Seer's and waiting for seconds for second stolen abilities (example: combinated Vacuum and Wall of Replica) and many different combination.
* A good positoning from Rubick's Spell Steal waiting steal abilities from Dark Seer 
Wall of Replica and illusion from Wall of Replica Dark Seer's can fighting with effect from outcome steal Wall of Replica from Rubick's.
* Combinated Rubick's steal Surge and 
Blink Dagger is very important catch from Dark Seer's and enemies.
* Rubick's 
Telekinesis can lifted up Dark Seer or enemy heroes and throw to Wall of Replica from Rubick's steal.
Dark Seer
* 
Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
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
* Heroes that avoid damage by coming in and out of invisibility in teamfights such as Weaver, 
Templar Assassin, and 
Riki will be easy for Zeus to reveal with Lightning Bolt and Thundergod's Wrath, but these heroes usually have other ways to avoid his damage or kill him, so he is not a perfect counter alone.
Additional:
* 
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.
Weaver
* Low-health, normally mobile carries with a lot of damage are vulnerable to Bane's nukes and disables: 
Anti-Mage, 
Clinkz, 
Drow Ranger, 
Faceless Void, 
Gyrocopter, 
Juggernaut, 
Luna, 
Meepo, 
Mirana, 
Monkey King, 
Morphling, 
Phantom Assassin, 
Phantom Lancer, Riki, 
Shadow Fiend, 
Slark, 
Sniper, 
Terrorblade, 
Troll Warlord, Weaver.
Weaver
* Earthshaker's many stuns can lock down slippery heroes like Slark in his 
Shadow Dance and Weaver in his Shukuchi.
Weaver
* Silences and other types of lockdown that prevent Weaver from using his spells: 
Silencer, Riki, Lion, 
Legion Commander, 
Shadow Shaman, 
Bane.
Dark Seer
* 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.
Weaver
* Silences and other types of lockdown that prevent Weaver from using his spells: Silencer, Riki, Lion, Legion Commander, Shadow Shaman, Bane.
Additional:
* Duel's long duration prevents Weaver from activating Time Lapse or escaping with Shukuchi.
Dark Seer
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as 
Disruptor's 
Kinetic Field or Slark's 
Pounce.
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.
Dark Seer
* In general, heroes who are melee with no way to fight back can be very easily poked by Monkey King to gain his Jingu Mastery stacks: 
Dark Seer, Riki, 
Rubick.
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
Dark Seer
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: 
Sven, 
Tiny, Wraith King, 
Dragon Knight, Meepo, 
Doom, Bounty Hunter, Dark Seer, 
Undying, 
Alchemist, Legion Commander.
Weaver
* 
Techies has both a silence and a powerful nuke in 
Blast Off!, root from 
Stasis Trap and even more magical damage in 
Proximity Mines and 
Remote Mines.
Weaver
* Weaver cannot Time Lapse out of Huskar's burn damage.
Weaver
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, 
Dazzle, 
Bristleback, 
Vengeful Spirit.
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.
Dark Seer
* Dark Seer's strength lies in his high-mana cost skills. So 
Mana Break can be a great nuisance for him, since it can reduce his mana and prevent him from casting his spells.
* 
Mana Void can deal a lot of damage if Dark Seer spent a lot of mana on his abilities.
Weaver
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, 
Arc Warden, Dark Seer.
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.
Dark Seer
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: 
Venomancer, 
Huskar, Ember Spirit, Dark Seer, 
Sand King, Doom, 
Dawnbreaker. However, this also means they are easily stunned.
Weaver
* Strong escape combo abilities from Spirit Breaker 
Charge of Darkness and 
Bulldoze can easily catch Shukuchi from Weaver. Since Spirit Breaker build Aghanim's Scepter, Charge of Darkness is very fast able to reach catch Weaver trying it.
* Time Lapse also affected Charge of Darkness and 
Nether Strike.
Additional:
* Shukuchi vision can easily target Charge of Darkness before Weaver purchase Linken's Sphere.
Weaver
* Heroes that usually build Linken's Sphere as a core or situational item: Weaver, 
Medusa, Morphling, Queen of Pain, 
Storm Spirit, Luna.
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.
Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: 
Beastmaster, 
Broodmother, 
Enigma, 
Nature's Prophet, 
Visage, 
Warlock, Wraith King.
Dark Seer
* The constant dispel from Demonic Purge will make any attempt to save the victim or himself by Surge become futile. For what it's worth, Demonic Purge will also dispel Ion Shell.
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.
Dark Seer
* Surge allows for Dark Seer and his allies to escape from Upheaval due to it ignoring any slow.
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.
Dark Seer
* Dark Seer's 
Vacuum and Ion Shell can clear a wave of Chen's Creeps effectively.
* Surge applies haste movement and negates the slow from 
Penitence, allowing Dark Seer to easily escape from Chen and his creeps.
* Dark Seer's full combo from Dark Seer's Vacuum, Wall of Replica and 
Normal Punch from Aghanim's Scepter can often kill Chen or any of his allies before he can save them with 
Hand of God.
Additional:
* Dark Seer's Vacuum and Ion Shell can clear a wave of Chen's Creeps effectively.
* Surge applies haste movement and negates the slow from Penitence, allowing Dark Seer to easily escape from Chen and his creeps.
* Dark Seer's full combo from Dark Seer's Vacuum, Wall of Replica and Normal Punch from Aghanim's Scepter can often kill Chen or any of his allies before he can save them with Hand of God.
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.
Dark Seer
* Dark Seer's Vacuum and Ion Shell allows him to clear a wave of Terrorblade's illusions.
* Because Terrorblade often builds items that require 
Ultimate Orb like 
Manta Style and 
Eye of Skadi, Dark Seer can create a very strong illusion of Terrorblade with Wall of Replica and Normal Punch from Aghanim's Scepter.
* If Dark Seer can use Vacuum to help teammates land their AoE abilities, Terrorblade will be quickly killed before he even gets a chance to use Sunder.

Weaver
* Heroes whose core item builds includes 
Monkey King Bar: Faceless Void, 
Windranger, Weaver, Juggernaut.
Dark Seer
* Dark Seer can increase the movement speed of allies with Surge, breaking Static Link.
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.
Dark Seer
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz, 
Pugna, Nature's Prophet, Dark Seer, 
Lycan, 
Tusk
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.
Dark Seer
* The haste provided by Dark Seer's Surge or a {Rune:Haste} renders your slows ineffective.
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.
Dark Seer
* Heroes with escape abilities : Anti-Mage Dark Seer Slark Storm Spirit Windranger Weaver can kite Lifestealer due to him having no lockdown
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.
Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.
Weaver
* 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 
Mana Break or 
Diffusal Blade, until Wraith King purchases Aghanim's Shard to remove 
Reincarnation's manacost.
Additional:
* 
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.
Dark Seer
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, 
Centaur Warrunner.
Weaver
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.
Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.
Weaver
* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.
Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.
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.
Dark Seer
* Dark Seer can pull together Spectre's illusions with Vacuum, and Wall of Replica creates an illusion of Spectre that deals massive damage.
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.
Dark Seer
* Ion Shell destroys 
Refraction's protection stacks in short time.
* Surge ignores the massive slow from 
Psionic Trap.
Weaver
* 
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.
Additional:
* 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.
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
* 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.
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.
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
* 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
* 
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.
Additional:
* 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.
Dark Seer
* Ion Shell is a very powerful weapon against Broodmother's Spiderlings and makes her laning much harder.
Additional:
* Ion Shell zones out Broodmother in the laning phase, and can kill her spiderlings if used on one Spiderling in a group.
* Vacuum can pull Broodmother out of the treeline.
Dark Seer
* Venomancer is a low health hero and low range hero who is easy to harass with Ion Shell on a creep in the early game.
* Venomancer depends entirely on all his slows to keep distance or chase, but since Surge ignores slows, it is nearly impossible for Venomancer to hunt or run away from Dark Seer or his surged teammates.
Dark Seer
* Ion Shell helps taking down illusions quickly, making it easy to identify the real Phantom Lancer.
* Surge allows Dark Seer and his teammates to run away from Phantom Lancer, who relies on his 
Phantom Rush to chase enemies.
Dark Seer
* 
Living Armor can be destroyed quickly with Ion Shell.
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.
Dark Seer
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, 
Keeper of the Light, Huskar, Dark Seer
Dark Seer
* With Normal Punch from Aghanim's Scepter, Dark Seer can gain an advantage against heroes who rely on evasion as Normal Punch has true strike: Phantom Assassin, Windranger, 
Hoodwink.
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
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, 
Night Stalker, 
Viper.
Dark Seer
* Heroes with hastes: Dark Seer, Lycan
Dark Seer
* With Normal Punch from Aghanim's Scepter, Dark Seer can gain an advantage against heroes who rely on evasion as Normal Punch has true strike: Phantom Assassin, Windranger, Hoodwink.
Weaver
* Heroes that are hard to kill without lockdown: Puck, Weaver.
Dark Seer
* With Normal Punch from Aghanim's Scepter, Dark Seer can gain an advantage against heroes who rely on evasion as Normal Punch has true strike: Phantom Assassin, Windranger, Hoodwink.
Weaver
* Heroes who can dodge Earth Spirit's abilities: Ember Spirit, Puck, Weaver
Weaver
* Heroes that rely on slows or low-duration stuns have trouble catching Weaver: 
Omniknight, 
Lich.
Weaver
* Escape-type carries: Slark, Storm Spirit, Weaver.
Weaver
* Heroes with one single-target abilities such as Wraith King, Necrophos, or Doom will struggle against Weaver's Linken Sphere.
Dark Seer
* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: Phantom Lancer, 
Chaos Knight, 
Naga Siren, Terrorblade.

Weaver
* A well-timed use of The Swarm provides vision over heroes with high mobility: Anti-Mage, Arc Warden, Dark Seer.
Dark Seer
* Heroes that rely on summons will suffer against Ion Shell, which kills them very quickly: Beastmaster, Broodmother, Enigma, Nature's Prophet, Visage, Warlock, Wraith King.
Dark Seer
* Strong laners are usually at a disadvantage because of how well Sven can jungle. Heroes such as Dark Seer. 
Underlord and Legion Commander may find that later Sven takes care of them very quickly after some jungle farming.
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.
Dark Seer
* Abilities that deal low damage with high amounts of instances are irrelevant against Pudge during Flesh Heap's active: Gyrocopter's 
Rocket Barrage and Dark Seer's Ion Shell are just a couple examples.
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.
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
Dark Seer
* Dark Seer can take great advantage of 
Divided We Stand by putting an Ion Shell on a clone in order to harass them effectively.
* Vacuum can take a single Meepo and disable him for Dark Seer and his teammates to take out.
Dark Seer
* A Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to 
Take Aim.
* However, an illusion of Sniper made with Wall of Replica is extremely powerful, and hard to deal with.
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.
Dark Seer
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as Disruptor's Kinetic Field or Slark's Pounce.
Dark Seer
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, 
Jakiro, Underlord, 
Leshrac, Dark Seer, 
Earthshaker, 
Timbersaw, 
Crystal Maiden.
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.
Weaver

Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Dark Seer
* Heroes with fast movement abilities will suffer huge damage when afflicted by Rupture:
Spirit Breaker, 
Earth Spirit, 
Dark Seer.
Rupture can deal a lot of damage to either a surged Dark Seer or his allies and prevent the target from getting into position.

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.
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.
