Dazzle
* 
Astral Imprisonment is a versatile nuisance:
* If it is cast on a low-enough-health unit at least 1 second into Shallow Grave's duration, the Shallow Grave will end during the imprisonment, and the target will take lethal damage when released.
* It can be used remove Dazzle from the fight at a time he could have saved someone.
* It lets himself or an ally dodge all of Poison Touch's effects, for long enough to recover their 
Blink Dagger.
Mars
* 
Arcane Orb's pure damage ignores Mars' Bulwark.
* Astral Imprisonment can be used to stop Mars from being disruptive or save allies from his abilities.
* 
Sanity's Eclipse deals high damage to Mars, due to his low intelligence pool.
Dazzle
* Pugna can turn out to be an effective hero against Dazzle due to the fact that he does not allow him to extend his 
Poison Touch with his 
Decrepify, which is why Dazzle cannot keep the enemy under prolonged deceleration.
* Pugna has a very strong ability against casters with a small health reserve - 
Nether Ward, which is why heroes like Dazzle will not be able to constantly throw their Poison Touch 
Bad Juju and 
Shadow Wave at enemies under the action of Nether Ward or will be forced to take a lot of damage
Additional:

* Pugna has a very strong ability against casters with a small health reserve - Nether Ward, which is why heroes like Dazzle will not be able to constantly throw their Poison Touch Bad Juju and Shadow Wave at enemies under the action of Nether Ward or will be forced to take a lot of damage
Mars
* 
Nether Blast, Decrepify and 
Life Drain deal high magical damage and bypasses Bulwark.
* Nether Ward reduces the amount of abilities Mars can use during fights and forces Mars to be careful about the heavy mana cost of Arena Of Blood.
* Pugna is one of few heroes that can contest Mars' ability to push and defend towers early on.
Dazzle
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (
Lina, 
Lion, etc.)
Additional:
* Laguna Blade can kill Dazzle quickly before he casts 
Shallow Grave.
Mars
* 
Dragon Slave deals reliable magic damage during the laning phase against Mars.
* Lina's 
Eul's Scepter of Divinity and 
Light Strike Array combo can interrupt Mars from being disruptive for a decent amount of time and leave him vulnerable for follow up stuns.
* 
Laguna Blade deals massive magical damage, and pure damage with 
Aghanim's Scepter.
Dazzle
* Some heroes with extreme range, like 
Zeus, 
Invoker or 
Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Mars
* Mars' own father is a formidable foe because Zeus deals massive amounts of magical damage. The high damage, low cooldown nukes of 
Arc Lightning and 
Lightning Bolt combined with the percent health magic damage of 
Static Field will shred Mars' health because it bypasses Bulwark completely.
Dazzle
* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, 
Enigma, Invoker, 
Pugna, 
Skywrath Mage, 
Tinker, Zeus, 
Oracle.
Mars
* 
Rage, acting as a pseudo-
Black King Bar, completely negates Mars' initiation if used in time.
* 
Feast does damage and heals based on max health, perfect against high-health strength heroes like Mars.
* 
Infest allows Lifestealer to potentially save allies from Mars' initiation with a quick burst of extra health.
Mars
* 
Decay, 
Soul Rip and 
Flesh Golem all deal magical damage which ignores Bulwark.
* Decay reduces Mars' natural strength and therefore his health pool, which is what he relies on to trade effectively in lane.
Mars
* Rebound allows her to jump in or out of the 
Arena Of Blood. She can save her allies from the Arena with Dispose as well.
Mars
* 
Nethertoxin breaks the damage block from Bulwark.
* 
Poison Attack and 
Viper Strike's slows make it difficult for Mars to contribute to fights due to his low mobility.
Additional:
* Viper Strike can disable 
Bulwark entirely, making Mars far less tanky. Using Nethertoxin inside Arena of Blood may discourage enemies from following up with Mars's initiation.
* 
Rod of Atos is currently common on Viper and keeps Mars in position long enough to be killed.
* However, Viper is not very tanky earlier in the game, so positioning against Mars is important for Viper since a well-timed 
Spear of Mars can be the end of Viper.
Mars
* It is difficult for Mars to trade blows with Ogre Magi in the early game thanks to his high base health, resistance and 
Ignite.
* 
Bloodlust can assist Ogre Magi or an ally in repositioning against Mars for its move speed bonus.
* 
Fireblast can interrupt and mitigate Mars from performing his skill combos, especially in combination with 
Multicast.
Dazzle
* Shallow Grave prevents Ice Blast's shatter for up to 5 seconds, but can mostly only delay it as Ice Blast's debuff lasts 10 seconds and prevents Shadow Wave from healing them.
Additional:
* 
Ice Blast negates healing from Shadow Wave, and lasts longer than Shallow Grave.
Mars
* Solar Guardian can save allies caught inside Arena of Blood.
Dazzle
* 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.
Mars
* 
Shadowraze deals magic damage and ignores Bulwark.
* 
Requiem of Souls deals magic damage and can fear Mars away, forcing him to turn around and therefore become vulnerable.
Mars
* 
Ball Lightning makes it almost impossible to catch Storm Spirit without someone else initiating for you.
* 
Overload is not reduced by Bulwark and the magical damage spam can wear down Mars quickly.
Additional:
* Storm Spirit's abilities all do magical damage, which can bypass Bulwark.
* Ball Lightning can escape through Arena of Blood and it is easy to dodge Spear of Mars.
Mars
* 
Snowball can protect Tusk and his teammates from a Spear of Mars' stun after an Arena of Blood, and with proper targeting, even bring them out of the Arena. This is especially noticeable in the earlier stages of the game before allies buy Black King Bar and rely on this less. Even during the late-game, Tusk can purchase a Blink Dagger to save allies that are caught before Black King Bars can be used by Blinking in and Snowballing out.
* 
Tag Team is a constant threat to Mars in-lane, as it deals significant damage and slow, making Bulwark slightly ineffective.
* It is worth noting that 
Ice Shards can be detrimental to Tusk's own team by creating terrain that Spear of Mars can latch on, though using it conservatively is a good enough solution in most cases.
Mars
* 
Swashbuckle is an auto attack and therefore ignores Mars' Bulwark.
* 
Shield Crash upgraded with Aghanim is an auto attack and therefore ignores Mars' Bulwark.
* 
Rolling Thunder makes him immune to magic, making Pangolier able to roll in and out of Mars' Arena Of Blood.
Mars
* 
Sticky Napalm slows turn rate, making it difficult for Mars to face frontwards, where Spear of Mars and Bulwark are effective. In combination with 
Firefly, which deals magic damage, Batrider can make quick work of Mars.
* 
Flaming Lasso disables Mars while enemies re-position themselves behind Mars to avoid Bulwark.
Mars
* Heroes that can save their allies can be a big problem for Mars: 
Dazzle, 
Omniknight.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Mars
* 
Ursa is a special mention because despite Bulwark diminishing most of the damage Ursa does, he is quite durable, especially with 
Enrage, discouraging the aggressive all-in playstyle of Mars; Ursa can simply not target Mars.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Mars
* Heroes with break abilities: 
Shadow Demon (with Aghanim's Scepter), 
Viper.
Mars
* 
Kunkka's 
Ghostship and 
Torrent disrupt fights in Arena Of Blood.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Mars
* Heroes with high health especially Strength heroes will take more damage on Sun Ray: 
Axe, 
Pudge, 
Bristleback, 
Mars.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Dazzle
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)
Mars
* 
Firestorm and 
Pit of Malice are very disruptive in team fights, completely matching Mars especially since it can all be cast inside Arena Of Blood and also does percentage-based magical damage, negating Bulwark.
* 
Dark Rift can save any allies of Underlord trapped in Arena Of Blood.
* 
Atrophy Aura allows Underlord to lane against Mars quite well since he does not have the best base damage during the early game.
* Underlord is a common carrier of both 
Pipe of Insight and 
Mekansm/
Guardian Greaves, allowing his team to combat Mars in the mid to late game.
Mars
* Heroes with strong area-of-effect damaging and/or disabling abilities will be able to intercept Underlord and his team when they exit from Fiend's Gate: 
Luna's Aghanim's Scepter upgraded 
Eclipse, 
Dawnbreaker's 
Solar Guardian, Axe's

Mars
* 
Blink Strike gives bonus backstab damage and can bypass Bulwark. Defensively, it could be used to teleport away from Mars, especially while inside Arena of Blood.
* 
Smoke Screen can interrupt Mars' skill combos, especially when cast inside Arena of Blood.
* 
Tricks of the Trade can be used to evade Mars' skills, which have a slight delay to them. It could also be used to buy himself time while trapped inside of Arena of Blood.
Additional:
* Bulwark is generally irrelevant against Riki as he primarily deals bonus damage from behind.
Mars
* Heroes who rely on their target to run away: 
Riki, 
Bounty Hunter.
Dazzle
* Although 
Counterspell's passive component doesn't protect Anti-Mage from the physical damage nukes from Poison Touch and Shadow Wave, a well-timed use of it will reflect Poison Touch back to Dazzle, slowing him in the process.
* This can be even more dangerous if Dazzle has an Aghanim's Shard, as Counterspell will reflect the hex back to Dazzle.
* 
Mana Break drains mana, which can be a problem for Dazzle, as all of his abilities have a high mana cost. This makes him especially vulnerable to 
Mana Void.
Mars
* Heroes who cannot fight back during Arena of Blood in the early and mid game: 
Abaddon, 
Anti-Mage, Broodmother, Luna, 
Sniper, 
Troll Warlord, 
Weaver, 
Clinkz.
Mars
* 
Burning Spear's magical damage is very troublesome for Mars in the laning stage.
* 
Life Break's percentage-based magical damage bypasses Bulwark, and can also be used to jump in or out of Arena Of Blood.
Dazzle
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, 
Vengeful Spirit.
Dazzle
* Doom can completely shut down Dazzle through 
Doom, as it prevents him from casting his abilities and, by extension, gaining Bad Juju stacks.
Mars
* Heroes who can disable Mars but cannot do any damage to him, meaning he just tanks their abilities: 
Doom, Magnus.
Dazzle
* 
Juxtapose and 
Doppelganger conjures too many illusions for Dazzle to deal with, given he has no inherent movement- or AoE-abilities.
* However, this can be partially solved with Aghanim's Shard-upgraded Poison Touch, as the hex instantly destroys illusions in an area as well as revealing the real Phantom Lancer when he's hiding among his army of illusions.
* 
Phantom Rush and 
Spirit Lance allow Phantom Lancer to trivially catch Dazzle even in the back line of a fight.
* Phantom Lancer has high base armor which counters Dazzle's physical damage based spells in lane.
* 
Diffusal Blade a natural item from Phantom Lancer can drains mana, which can be a problem for Dazzle, as all of his abilities have a high mana cost.
Mars
* Heroes who lack burst damage will have a hard time against Mars: 
Phantom Lancer, 
Nature's Prophet, 
Lich.
Dazzle
* 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.

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.
Mars
* Bulwark negates most of the physical damage from Terrorblade and his illusions.
* God's Rebuke and Spear of Mars can decimate Terrorblade's illusions quickly.
Dazzle
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, Abaddon.
Mars
* Bulwark blocks much of Slark's basic attack damage, even during 
Shadow Dance.
* Slark finds it very difficult to have a good early/mid game when pressured in the early game by Spear of Mars and God's Rebuke.
* Spear of Mars and God's Rebuke can hit Slark through Shadow Dance and 
Depth Shroud.
* Should 
Pounce be on cooldown, Slark is very vulnerable inside Arena of Blood.
Dazzle
* 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.
Mars
* Bulwark mitigates 
Omnislash which deals physical damage, severely reducing its damage.
* Omnislash switch to opposite direction with each slash, so Mars can easily reduce most of its damage.
* However because {Ability ID:Blade Fury|Juggernaut} gives spell immunity Juggernaut can easily escape from {Ability ID:Arena Of Blood|Mars}.
Additional:
* Juggernaut deals mostly physical damage, which is easily mitigated with Bulwark.
* Juggernaut's Omnislash switches to opposite directions which each slash, so Mars can mitigate most of its damage since he only takes full damage from one direction: his back.
Dazzle
* 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.
Additional:
* 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 allows Dazzle Shadow Wave directly on Io and it's Tethered target which can also 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.
Mars
* Heroes that are hard to gank: Axe, Death Prophet, Phantom Lancer, 
Slark, 
Centaur Warrunner, Bristleback, Medusa, Mars.
Dazzle
* Bloodseeker's 
Thirst, 
Rupture, and huge AoE silence Blood Rite can fare well against Dazzle.
Dazzle
* Shallow Grave prevents Bloodseeker from replenishing his health by finishing off enemies.
Mars
* Arena Of Blood prevents Bloodseeker from attacking a Ruptured target.
* Bulwark helps Mars survive Rupture ganks simply by turning towards Bloodseeker without moving.
* Spear of Mars and God's Rebuke can push Bloodseeker from Ruptured targets.
Mars
* 
Legion Commander is both good and bad vs Mars, on the plus side she can dispel Spear of Mars with 
Press the Attack and is a good 
Silver Edge carrier. However, Mars is not an ideal 
Duel target, as Bulwark will force her to 1: Buy Silver Edge, and 2: Hit Mars with it before the Duel, allowing a skilled Mars to react, especially with Eul's Scepter of Divinity. In teamfights, Mars will happily draw attention after using his abilities, and tank the Duel with all spells on cooldown.
Dazzle
* 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.
Mars
* Because Duel requires both combatants to face each other, Bulwark's effectiveness will be increased by a huge margin, which makes it much more difficult for Legion Commander to win any duels against him.
* Spear of Mars and 
God's Rebuke pushes Legion Commander away during Duels against allies.
Additional:
* Bulwark immensely mitigates Duel, even with bonus physical damage, as Bulwark scales by percentage. Mars can also buy time for a dueled ally by pushing Legion Commander away with Spear of Mars.
Dazzle
* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, 
Arc Warden, Lion, 
Huskar, 
Shadow Shaman, 
Visage, 
Undying, Jakiro.
Mars
* Durable heroes: Axe, Dawnbreaker, Bristleback, Mars, Omniknight, 
Tidehunter, 
Wraith King, 
Primal Beast, Underlord.
Dazzle
* 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.
Mars
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, Broodmother, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Dazzle
* 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.
Mars
* If visible, Mars can knock Monkey King off his 
Tree Dance with God's Rebuke, as well as Spear of Mars. Arena of Blood also destroys a large swath of trees, which can disrupt Monkey King's positioning and turn him vulnerable should he choose to hide in trees.
* Mars can endure 
Jingu Mastery attacks simply by facing him with Bulwark.
* Mars can end Wukong's Command early by displacing Monkey King with a well-thrown Spear of Mars. Mars can also endure most of his clones with Bulwark.
Additional:
* Monkey King's natural reliance on trees makes him an exceptionally prime target for Spear of Mars. Should Monkey King use Mischief to disguise himself, it will still hit him, stunning him in the process.
* God's Rebuke easily pushes Monkey King out of Wukong's Command.
Mars
* Even if he can slow Mars down with 
Shrapnel and 
Headshot, Mars can tank Sniper's physical damage simply by facing him with Bulwark, allowing him to endure his auto-attacks into the late-game. Should Sniper choose to attack someone else, Mars can redirect his projectiles with Bulwark's active ability.
* Sniper's poor mobility makes him very vulnerable to Arena of Blood, especially in the early game. Mars can also take advantage of this by pushing him closer to the front line with Spear of Mars.
Mars
* As long as Mars is facing her with Bulwark, even if pushed away with 
Gust, Drow Ranger will do no effectual damage against him. Mars' ability to endure her onslaught usually gives him enough time to cast Arena of Blood, of which she has a very slim chance surviving without Gust.
* With Bulwark's active ability, Mars can protect allies pursued by Drow Ranger by redirecting her projectiles to his shield instead.
Mars
* 
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.
Mars
* Bulwark blocks the attack from Meepo and his clones.
* Spear of Mars & God's Rebuke prevents Meepo and his clones from initiation or escaping.
Mars
* Heroes with forced movement abilities or non-interrupting forced movement, such as Lion, 
Drow Ranger, Magnus, Mars, as they can cancel blast-off mid air, removing his ability to initiate or escape.
Mars
* Heroes that can negate Hoodwink's mobility: Kunkka, 
Disruptor, Mars.
Mars
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: 
Sven, Omniknight, Enigma, Luna, Naga Siren, Mars, Jakiro, Venomancer, Elder Titan, 
Faceless Void, 
Rubick, Keeper of the Light, Pugna, Invoker, 
Spectre, Alchemist, Treant Protector, Lina, Oracle, Zeus, Shadow Shaman, 
Phoenix, Razor, Huskar, Batrider, Kunkka, Tidehunter, Wraith King, Sand King, Medusa, Dawnbreaker.
Mars
* Heroes who lack burst damage will have a hard time against Mars: Phantom Lancer, Nature's Prophet, Lich.
Dazzle
* 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.
Mars
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, Broodmother, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Dazzle
* 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.
Mars
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, Broodmother, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Dazzle
* Dazzle's lack of a true disable makes him a relatively vulnerable target for Phantom Assassin.
* Coup de Grace will often kill Dazzle's teammates before he has a chance to use Shallow Grave.
Dazzle
* Hex abilities prevent attacking, ability and 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: Doom, Disruptor with Aghanim's Scepter, Dazzle with Aghanim's Shard
Mars
* Phantom Assassin's high physical damage is greatly reduced by Bulwark.
* God's Rebuke has true strike, ignoring the evasion from 
Blur.
Mars
* Heroes who lack burst damage will have a hard time against Mars: Phantom Lancer, Nature's Prophet, Lich.
Mars
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
Mars
* Heroes that are hard to gank: 
Dragon Knight, Mars, Centaur Warrunner.
Dazzle
* Heroes with armor reducing abilities greatly hinder Visage's defense like 
Slardar and Dazzle.
Mars
* Heroes with the capability of removing or destroying trees greatly hinders the effectiveness of Treant Protector's abilities: Batrider, Nature's Prophet, Lina, Enigma, Mars
Mars
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, Broodmother, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Dazzle
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned Drow Ranger and Sniper) and supports (like Dazzle and Shadow Shaman).
Mars
* Spectre cannot have a good game if she is pressured heavily in lane, which is something Mars can do. He may even force her to cast 
Haunt as an escape, putting it on a long cooldown.
* Should Spectre get to the late game, Mars can block a large amount of her damage with Bulwark and can mitigate some of the chaos caused by her Haunt illusions with God's Rebuke.
Dazzle
* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Dazzle
* 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.
Additional:
* 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.
Mars
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: Puck, 
Void Spirit, Mars.
Dazzle
* 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

Mars
* Medusa's Stone Gaze forces Mars to choose between getting petrified, or turning his vulnerable back on Medusa.
Mars
* Bulwark can make each of Medusa's attacks target him instead, reducing Medusa's contribution on team fights.
* Spear of Mars stuns Medusa and also pushes her away from teamfights, taking advantage of Medusa's low mobility.
* Arena Of Blood blocks Medusa's attacks from outside the arena.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Dazzle
* Shadow Wave provides good sustain against Tinker's spammable abilities.
* Shallow Grave can stop Tinker from bursting down a target.
Mars
* Venomancer's spells all deal magical damage, ignoring Bulwark.
* Venomancer's multiple slows are especially effective at kiting Mars.
* 
Plague Ward can attack through Arena Of Blood.
Additional:
* Venomancer's poison attacks are all magical damage, ignoring Bulwark.
* Venomancer's multiple slows are especially effective against Mars' low mobility.
* Plague Wards can attack through Arena of Blood.
Dazzle
* 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
* 
Mirror Image's illusions can easily walk straight at Dazzle and attack him, due to Dazzle's lack of reliable AoE nukes or disables.
* 
Ensnare roots Dazzle or his allies, making it harder to stay in range of Dazzle's saving abilities.
* Song of the Siren can be used to initiate a fight with superior positioning, potentially zoning Dazzle's high-impact spells out of the fight.
Dazzle
* 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.
Mars
* Time Dilation while Spear of Mars and God's Rebuke are on cooldown will make these abilities unusable for a long time, rendering Mars nearly useless.
* Mars cannot turn inside the Chronosphere, which makes it easy to attack him from the back, bypassing Bulwark completely.
Additional:
* 
Time Walk allows Faceless Void to escape or enter Arena Of Blood, and helps him recover from Mars' burst damage.
* 
Time Lock's magical damage ignores Bulwark.
* 
Chronosphere allows Faceless Void to reposition behind Mars, ignoring his Bulwark while he is helplessly frozen in time.
Dazzle
* 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.
Mars
* Necrophos' largely magical damage completely ignores Bulwark.
* 
Ghost Shroud protects Necrophos from God's Rebuke but more importantly stops Mars from being a threat in lane.
Dazzle
* 
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!
Additional:
* 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.
Mars
* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, 
Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, 
Witch Doctor, Zeus.
Dazzle
* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, Dazzle from Aghanim's Shard with upgraded Poison Touch.
Dazzle
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: Shadow Shaman, Visage, Dazzle, Rubick, Lich.
Mars
* Heroes who cannot fight back during Arena of Blood in the early and mid game: Abaddon, Anti-Mage, Broodmother, Luna, Sniper, Troll Warlord, Weaver, Clinkz.
Dazzle
* Culling Blade ignores the protection from
Shallow Grave and will kill any target whose health is low enough. This makes Axe one of the hardest counters to Dazzle, and he neutralizes one of Dazzle's most important abilities.
Culling Blade kills any target under the health threshold, even through Shallow Grave.

Mars
*
Berserker's Call forces Mars to face in the direction choosen.
Counter Helix deals pure damage and can go through Bulwark.
