* Dazzle can instantly destroy all of Naga Siren's illusions from Mirror Image with Aghanim's Shard upgraded Poison Touch used on her or any of her illusions.

* Doom, Disruptor with Aghanim's Scepter, Dazzle with Aghanim's Shard, and hex abilities all prevent item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. Doom and Shadow Demon with Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility.

* Heroes with illusions and summons can be hard for Phantom Assassin to deal with, as she lacks any AoE abilities to deal with them without items: Broodmother, Phantom Lancer, Chaos Knight, Lycan, Naga Siren, Shadow Shaman, Visage, Nature's Prophet, Terrorblade, Warlock, Wraith King.

* Shallow Grave prevents Bloodseeker from replenishing his health by finishing off enemies.

* Heroes with the ability to heal allies, or those with good defensive abilities: Chen, Dazzle, Io, Oracle, Omniknight, Witch Doctor, Winter Wyvern, Abaddon, etc.

* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.

* Poison Touch severely slows down Chen, deals damage over time and weakens his armor every time he gets attacked by Dazzle or any of his allies. Aghanim's Shard upgraded Poison Touch can hex Chen and prevent him from saving his allies with Hand of God.
* Neither Chen nor his converted creeps have burst damage at all, so Dazzle will always have plenty of time to save his allies with Shallow Grave.
* Dazzle can use Shadow Wave can heal his allies, kill Chen's creeps and damage Chen himself.
* Bad Juju can weaken Chen's armor, and the armor of his creeps every time Dazzle casts a spell while strengthening armor of Dazzle's allies.

* Lycan can clear waves of Chen's creeps with his wolves from Summon Wolves, especially once Lycan takes +2 Wolves summoned talent. And even though Chen can convert one of his wolves with Holy Persuasion, Lycan can counter this by buying Helm of the Overlord to regain control of it. Uncontrollable wolves summoned from Aghanim's Shard upgrade Summon Wolves cannot be converted with Holy Persuasion.
* Shapeshift allows him to chase down Chen and kill him easily.
* Howl can reduce attack damage of both, Chen and his creeps.

* Aghanim's Shard upgraded Poison Touch can be used to easily kill many of Terrorblade's illusions from both Conjure Image and Manta Style, it can also hex the real Terrorblade, silencing him, disarming him, slowing him, muting him and rendering him unable to do anything at all.
* Shallow Grave can be used to save an ally whom Terrorblade has used Sunder on under the condition Dazzle is quick enough to do it. And since Terrorblade has no "real" burst damage potential outside from Sunder, Dazzle will usually have plenty of time to save an allied hero on which Sunder was used.
* Shadow Wave will always damage Terrorblade and his illusions whenever Terrorblade has no Metamorphosis available to use, while healing Dazzle's allies. Aghanim's Scepter upgraded Shadow Wave can also be used directly on Terrorblade, and bounce on both Terrorblade and his illusions alike, causing them to take damage and to be attacked by Dazzle. Shadow Wave can also pierce throught debuff immunity by Black King Bar, one of the items Terrorblade relies on to survive in teamfights.
* Bad Juju can weaken Terrorblade's armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.

* Bad Juju can weaken Terrorblade's armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.

* Heroes who can summon illusions and summons because Terrorblade has no abilities to deal with multiple enemies at once outside Reflection: Shadow Shaman, Naga Siren, Broodmother, Lycan, Enigma, Chaos Knight, Phantom Lancer, Shadow Demon, Dark Seer, Nature's Prophet, Invoker, Morphling, Visage, Grimstroke with Aghanim's Scepter.

* Poison Touch allows Dazzle to harass both, Io and it's tethered target on lane. Aghanim's Shard upgraded Poison Touch can also hex both, Io and it's tethered target, preventing them from escaping with Relocate, and also disarming them, silencing them, muting them and rendering them helpless against Dazzle and his allies.
* Io's damage output is one of the weakest, therefore Dazzle will have plenty of time to save an ally with Shallow Grave from gank by Io and it's tethered target.
* Shadow Wave will always hit both, Io and it's tethered target if they are near the ally Dazzle uses Shadow Wave on, while healing Dazzle's allies near them. Aghanim's Scepter upgraded Shadow Wave can bounce on both, Io and it's tethered target, causing them both to take damage and to be attacked by Dazzle. And unlike Io who doesn't get healed while using Tether, Shadow Wave will always heal Dazzle no matter on which of his allies he uses it on.
* Bad Juju will cause both, Io and it's tethered target to lose armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.

* Heroes with low armor and little mobility, like Huskar, Io, etc. will also have an unfortunate fate.

* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.

* Heroes with low armor and little mobility, like Huskar, Io, etc. will also have an unfortunate fate.

* He can send wolves to defuse Proximity Mines, and he can catch up Techies and kill him before they can deny themselves. Even if the suicide is successful, Lycan can still survive because of his tankiness.

* Shapeshift allows Lycan to get close and disable Marksmanship.
* Shapeshift also makes him immune to slows like Drow Ranger's Frost Arrows.
Additional:
* The Wolves's speed causes the knockback from Gust to be ineffective.
* Drow Ranger lacks escapes and loses her Marksmanship when someone is near her. Lycan can take advantage of these weaknesses of Drow Ranger.

* Mirana's Leap is ineffective if Lycan uses Shapeshift. It also allows him to dodge Sacred Arrow.

* Shapeshift allows Lycan to chase down Earth Spirit.

* Lycan's ultimate makes him immune to slows from Ursa's Earthshock as well as allowing him to outmaneuver Ursa during Enrage. Lycan can also easily chase down Ursa while shapeshifted, should Ursa try to flee.

* Howl reduces a good chunk of Marci's attack damage that she relies heavily on, and the armor reduction works better on her because of her low armor.
* Shapeshift renders Lycan immune to slow from Rebound and Unleash.

* Shapeshift allows Lycan to escape from Upheaval with maximum movement speed.
* Warlock doesn't have a good solution to deal with Lycan's wolves from Summon Wolves.

* Lycan doesn't care much about Lich's slows thanks to Shapeshift.
* Chain Frost can bounce to the wolves that Lycan summons.
Additional:
* Lich possesses a lot of slows, which Lycan doesn't care about when he Shapeshifts.
* Lich has no in-built escape, which makes him a good target for Lycan.

* Void's slow is useless against Lycan by activating Shapeshift.
* Night Stalker's single target abilities (with the exception of Void upgraded by Aghanim's Scepter) is not very effective against Lycan's Summon Wolves during the early and mid game.

* Lycan's high health allows him to easily shrug off Nyx Assassin's burst damage and fend him off.
* As Lycan commonly buys Black King Bar, he can use it to freely attack Nyx Assassin and chase after him with Shapeshift.

* Venomancer's damage-over-time abilities are easier to heal through with numerous Shadow Waves than other types of damage, and it's simple to time a Shallow Grave until the last possible second to save a teammate from them.

* Dazzle's Shadow Wave is a spammable healing ability that spreads around his entire team, slowing the death of his teammates as effectively as Necrophos spreads damage to them.
* If not immediately, Shallow Grave delays his ally from gradually dying to Necrophos's abilities, especially Reaper's Scythe.
* However, bear in mind that Dazzle's Poison Touch, Shadow Wave and Bad Juju all deal physical damage, and Dazzle has no abilities to help him deal magical damage at all, which can cause problems for Dazzle to kill Necrophos if he uses Ghost Shroud to protect himself.
Additional:
* Reaper's Scythe is very predictable and gives Dazzle plenty of time to react with Shallow Grave: Dazzle just has to keep a close eye on his allies below 50% health.
* However, Dazzle must be sure to use Shadow Wave on that ally immediately after, or they will die from Heartstopper Aura when the Shallow Grave ends!

* Shadow Wave provides good sustain against Tinker's spammable abilities.
* Shallow Grave can stop Tinker from bursting down a target.

* Magnetic Field is useless against melee heroes, so Lycan can attack Arc Warden without missing.
* Flux doesn't affect Lycan that much, because Shapeshift grants immunity to slows and because he is never alone.
* If their Tempest Double has been called, Lycan can still kill Arc Warden before the double expires.

* 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

* Heroes that can save their allies can be a big problem for Mars: Dazzle, Omniknight.

* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.

* Lycan and Weaver has abilities that allow them to move at maximum movement speed, and those abilities can't be dispelled, potentially wasting the slow from Demonic Purge.

* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, Chaos Knight, Naga Siren (bonus for her Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, Queen of Pain, Shadow Shaman (Shackles), Jakiro, Pugna, Doom

* Windranger's has bad against Hero heavily strong escape out of reach with windrun: Spirit Breaker, Lycan, Storm Spirit, Earth Spirit

* Heroes with abilities that can save teammates are also effective such as Shadow Demon, Dazzle, Oracle, Bane, Pugna, Tusk, Winter Wyvern, Io, Underlord, Treant Protector and Keeper of the Light.

* Once you get a Black King Bar, squishy spellcasters like Zeus, Skywrath Mage and others will be probably easy to deal with.

* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: Clinkz, Pugna, Nature's Prophet, Dark Seer, Lycan, Tusk

* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.

* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.

* Heroes with summons: Lycan, Broodmother, Visage, Nature's Prophet, Warlock.

* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: Brewmaster, Dazzle, Tidehunter.

* Heroes with single-target abilities will be overwhelmed by Lycan and his summons: Wraith King, Bane, Phantom Assassin.

* Once he buys Aghanim's Shard, Dazzle's Poison Touch can hex enemies, and hex can instantly kill illusions, making Dazzle strong against heroes who rely on illusions. Bear in mind that Chaos Knight is the exception because his Phantasms are strong illusions that are immune to abilities that can instantly kill illusions.

* Heroes with armor reducing abilities greatly hinder Visage's defense like Slardar and Dazzle.

* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's steady damage output, Dazzle has plenty of time to Shallow Grave anyone Clockwerk initiates on.
Additional:
* Aghanim's Shard upgraded Poison Touch can be used to hex Clockwerk, silencing him, disarming him, slowing him, and muting him, and thus rendering him unable to use Blade Mail to return damage or to do anything at all.
* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's very low damage output, Dazzle will have more than enough time to Shallow Grave any enemy hero Clockwerk initiates on.

* A Lycan with Shapeshift can always run down Puck for a very quick kill due to its low armor. It is important to abuse as many cliffs and trees as possible to escape from a Lycan.

* Shallow Grave prevents Legion Commander from killing her opponents in Duels.
* Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.

* Shallow Grave can prevent the death of an ally that is trapped inside the Chronosphere.
* Shadow Wave lets Dazzle heal allies and damage enemies from outside Chronosphere.

* The movement speed granted from Shapeshift means that Spectre has no way to punish Lycan if he wants to splitpush or pick off supports. Furthermore, he will kite Haunt and cannot be slowed by Spectral Dagger.
* Lycan is often part of an early game push strategy which is often the best counter to Spectre because she needs a lot of time and space to come online as a late game carry.

* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc Warden, Lion.

* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan.

* Heroes with hastes: Dark Seer, Lycan

* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, Abaddon.

* 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.

* Shapeshift increases Lycan's movement speed and renders him unslowable, allowing him to easily avoid and escape Ancient Apparition's abilities.
* Lycan has fast summons, both his wolves from Summon Wolves can do heavy damage to Ancient Apparition due to his immobility and low armor.

* Zeus can deal a huge amount of damage, but he lacks defensive abilities, such as good mobility or resistance. Due to that, he doesn't like to be touched by any means. Heroes with higher damage output and good mobility will often get easily near Zeus and trade damage (eventually causing Zeus's downfall). Such Heroes include: Lycan, Slark, Storm Spirit, Spectre and others.
