Mirana
* Heroes with spells that negate invisibility such as 
Bounty Hunter, 
Zeus and 
Slardar prevent her from saving her allies with Moonlight Shadow.
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.
Mirana
* Heroes that can protect or dispel stunned allies such as 
Legion Commander, 
Outworld Destroyer, 
Shadow Demon and 
Oracle can reduce the effectiveness of Sacred Arrow.
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.
Mirana
* Heroes who rely on invisibility, such as Bounty Hunter, 
Clinkz, 
Mirana, 
Nyx Assassin and 
Riki, as they will be revealed if caught by Chronosphere.
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.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: 
Anti-Mage, 
Queen of Pain, 
Storm Spirit, Riki.
Mars
* 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.
Additional:
* 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.
Mirana
* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Destroyer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: 
Timbersaw, 
Dark Willow, 
Enigma, 
Invoker, 
Pugna, 
Skywrath Mage, 
Tinker, Zeus, Oracle.
Mirana
* Heroes with summons or illusions makes Sacred Arrow harder to land: Shadow Demon, 
Phantom Lancer, 
Nature's Prophet.
Mars
* Heroes with break abilities: Shadow Demon (with 
Aghanim's Scepter), 
Viper.
Mirana
* 
Flux will slow and damage Mirana even after she Leaps, since she will likely not be near allies.
* Arc Warden can place 
Magnetic Field on an ally who has been hit by Sacred Arrow to protect them.
Additional:
* Arc Warden can use his summons to prevent 
Sacred Arrow from hitting himself or his allies.
* Mirana doesn't build items that give armor often, so she usually can't fight against a late game Arc Warden.
Mirana
* Mirana's Leap is ineffective if Lycan uses 
Shapeshift. It also allows him to dodge Sacred Arrow.
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.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
Mars
* Bulwark is generally irrelevant against Riki as he primarily deals bonus damage from behind.
Additional:
* 
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.
Mars
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
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.
Mars
* Solar Guardian can save allies caught inside Arena of Blood.
Mars
* 
Nethertoxin disables Bulwark entirely, making Mars far less tanky. Using Nethertoxin inside Arena of Blood may discourage enemies from following up with Mars' initiation.
* 
Rod of Atos is currently common on Viper and keeps Mars in position long enough to be killed.
* Beware that Viper is not very tanky earlier in the game, so positioning against Mars is important since a well-timed Spear of Mars can be the end of Viper.
Additional:
* 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.
Mars
* 
Berserker's Call forces Mars to face in the direction choosen.
* 
Counter Helix deals pure damage and can go through Bulwark.
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.
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.
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
* 
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
* 
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
* 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
* 
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
* 
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.
Mirana
* Puck can initiate on Mirana with 
Waning Rift to prevent her from going invisible or Leaping.
* A Mirana caught in 
Dream Coil will stun herself if she tries to Leap away.
* Puck's Burst damage takes advantage of Mirana's below average health.
* Puck can easily dodge Sacred Arrow and Starstorm with 
Phase Shift.
Additional:
* Mirana's spells are laid out to assassinate enemies. Puck can easily avoid the slow moving Sacred Arrow, and also can avoid 
Starstorm with Phase Shift, since the meteors have a delay.
* If Puck casts either Waning Rift or Dream Coil in the area, Mirana cannot 
Leap away.
Mirana
* 
Windrun quickly dodge Mirana's Sacred Arrow and misses her attacks.
* 
Shackleshot through tree with 
Focus Fire via Aghanim's Scepter combo can kill Mirana quickly, before using Leap or Moonlight Shadow.
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
* Nukers who have set amounts of damage will really struggle against Lone Druid especially in True Form: 
Puck, 
Void Spirit, 
Mars.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Mirana
* Heroes with spells that negate invisibility such as Bounty Hunter, Zeus and Slardar prevent her from saving her allies with Moonlight Shadow.
Mars
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.
Mars
* Heroes that can save their allies can be a big problem for Mars: 
Dazzle, 
Omniknight.
Mirana
* Heroes with silences and hard stuns such as 
Doom, 
Silencer, and 
Lion can keep Mirana from Leaping away.
Mirana
* 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.
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.
Mirana
* Heroes that cannot move in fights such as a 
Dueling Legion Commander or anyone channeling a spell like 
Bane, 
Pudge, or Enigma are easy Sacred Arrow targets.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
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.
Mirana
* Heroes that rely on invisibility can be tracked with Charge of Darkness opening them to team attacks: Bounty Hunter, Mirana, Riki
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 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.
Mirana
* The long silence of 
Crippling Fear at night prevents Mirana from escaping with Moonlight Shadow and Leap. She also has really low base health, so Night Stalker can usually kill her during one cast of Crippling Fear at night.
* With 
Dark Ascension and 
Gem of True Sight, Night Stalker can find and kill Mirana, and he is a tanky hero capable of fighting Mirana any stage of the game.
Mars
* Heroes that are hard to gank: 
Dragon Knight, Mars, 
Centaur Warrunner.
Mirana
* Though Mirana can clear waves of Broodmother's spiderlings with Starstorm, Broodmother will often stick with her spiderlings from 
Spawn Spiderlings, which in combination with the huge speed provided by 
Spin Web can make it hard for Mirana to hit her with Sacred Arrow.
* Broodmother commonly buys 
Orchid Malevolence and it's upgrade 
Bloodthorn, which allows her to prevent Mirana from escaping with both, Leap and 
Moonlight Shadow and from fighting back with Starstorm.
Additional:
* Though Mirana can clear waves of Broodmother's spiderlings with Starstorm, Broodmother will often stick with her spiderlings from Spawn Spiderlings, which in combination with the huge speed provided by Spin Web can make it hard for Mirana to hit her with Sacred Arrow.
* Broodmother commonly buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to prevent Mirana from escaping with both, Leap and Moonlight Shadow and from fighting back with Starstorm.
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
* 
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.
Mirana
* Mirana can destroy Tombstone, and evade zombies using Leap and Moonlight Shadow's invisibility.
Mars
* 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.
Additional:
* 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.
Mirana
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: 
Arc Warden, 
Chen, Clinkz, Drow Ranger, 
Lina, Mirana, Nature's Prophet, Pugna and Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
Mirana
* Abaddon can remove Sacred Arrow's stun from his teammates with 
Aphotic Shield, or remove it from himself with 
Borrowed Time.
* Borrowed Time makes Abaddon almost impossible to burst down with Mirana's Aghanim's Scepter combo.
Additional:
* Sacred Arrow can be instantly dispelled by Aphotic Shield.
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.
Mirana
* 
Track detects Mirana and her allies during Moonlight Shadow.
Mars
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
Mirana
* Mirana can use Leap to jump right next to Drow Ranger or can approach her while under cover of the invisibility granted by Moonlight Shadow, which cancels the bonus granted to Drow Ranger by 
Marksmanship.
* Her low health makes her easy to burst down with Mirana's spells, especially with Aghanim's Scepter.
* Mirana can dodge 
Gust with good reaction time, or Leap away if Drow tries to slow her without Gust.
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.
Mirana
* Techies spends lots of time standing still planting stacks of 
Land Mines away from creep waves.
* Sacred Arrow can be used to scout hidden Land Mines among trees and at uphill places. It can also be used to catch Techies while he's planting them.
* If Techies is hit with a Sacred Arrow, he can be killed before he has a chance to use 
Blast Off!.
* Mirana has a high attack range to destroy his traps from a safe distance.
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.
Mirana
* Sacred Arrow's long stun duration can prevent Morphling from casting his Waveform or Morph Replicate, making him unable to escape and easier to gank.
* Moonlight Shadow also allows Mirana's team to surprise Morphling while he tries to push towers.
* Mirana usually buys 
Linken's Sphere to protect herself from single-target abilities, making Morphling's Adaptive Strike and 
Ethereal Blade harder to use on her.
* However, Mirana also provides a chance to become a good Morph target, allowing Morph to use Leap to run away, if necessary.
Mirana
* Sacred Arrow can be used to interrupt Freezing Field from a safe distance, forcing her to cancel it to dodge or get hit.
* Crystal Maiden has very slow movement speed, making her an easy Sacred Arrow target.
* Crystal Maiden has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.
* If 
Frostbite has already been used, Mirana can Leap away even when slowed by 
Crystal Nova or 
Freezing Field.
Mars
* 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.
Additional:
* 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.
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.
Mirana
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
Mirana
* Counterspell does not protect Anti-Mage from Sacred Arrow.
* Moonlight Shadow can help her allies avoid Mana Break and Mana Void.
* Blink's cooldown isn't short enough to escape from Leap, especially when she has the extra charge from 
Aghanim's Shard.
Additional:
* Combo items for Mirana Rod of Atos can upgrade to 
Gleipnir and Sacred Arrow before and during Anti-Mage build item 
Manta Style cooldown can easy penetrates Counterspell broken.
* Charge for Leap can Mirana easily faster escaping.
* Moonlight Shadow it can disappear anytime and Anti-Mage can not fight.
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
* 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.
Mirana
* Sacred Arrow can be used to interrupt Death Ward from a safe distance, forcing him to cancel it to dodge or get hit.
* 
Paralyzing Cask is a slow-moving stun, and Mirana can Leap away from her allies to keep it from bouncing.
* Witch Doctor has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.
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
* 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.
Mirana
* Leap allows Mirana to easily escape the freezing range of Cold Feet. Mirana also tends to build Manta Style which dispels Cold Feet.
* During Moonlight Shadow, the invisibility makes it hard to catch Mirana's team with Ice Blast.
* Ancient Apparition's lack of mobility/escape capabilities makes him an easy target for Mirana at any stage of the game.
Mirana
* Mirana can disturb Shadow Shaman's channeling even if he is under the effect of invisibility thanks to Sacred Arrow.
* Mirana armed with an Aghanim's Scepter is known to be able to quickly burst down heroes - especially supports. Together with Ethereal Blade the bullying towards Shadow Shaman can continue for the whole match.
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 with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, 
Batrider, 
Earthshaker, 
Elder Titan, Faceless Void, Invoker, Legion Commander, Mars, 
Primal Beast, Riki, 
Shadow Shaman, Silencer, 
Vengeful Spirit, Void Spirit.
Additional:
* 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.
Mars

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.
Mirana
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
Additional:
* If Meat Hook is used before Leap, Mirana may be able to escape Pudge's grasp by leaping to safety.
* The invisibility from Moonlight Shadow gives a degree of mobility, which can make Mirana or her teammates difficult targets to hook.
* Sacred Arrow can be used to cancel Dismember from long distances.
Mars
* Heroes who lack burst damage will have a hard time against Mars: Phantom Lancer, Nature's Prophet, 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.
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.
Mirana
* Mirana can instantly kill creeps with Sacred Arrow, making her decent at crippling the armies of Chen or 
Enchantress.
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.
Mirana
* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Destroyer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
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.
Mirana
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
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.
Mars
* Kunkka's 
Ghostship and 
Torrent disrupt fights in Arena Of Blood.
Mirana
* Leap allows Mirana to easily escape Torrent and Ghostship.
Mirana
* Even though Luna is the kind of hero that Mirana can handle due to Moonlight Shadow rendering her safe from 
Eclipse with Moonlight Shadow, smart Luna can buy 
Dust of Appearance, allowing her to provide vision on her to her team, and possibly, kill Mirana.
* Luna's high movement speed allows her to evade Sacred Arrow, giving Mirana difficulties in hitting her with it.
* Aghanim's Scepter upgraded Eclipse combined with Dust of Appearance allows Luna to cast it on a hero that is struck by Sacred Arrow and/or after Mirana jumps in with Leap.
Additional:
* Even though Luna is the kind of hero that Mirana can handle due to Moonlight Shadow rendering her safe from Eclipse with Moonlight Shadow, smart Luna can buy Dust of Appearance, allowing her to provide vision on her to her team, and possibly, kill Mirana.
* Luna's high movement speed allows her to evade Sacred Arrow, giving Mirana difficulties in hitting her with it.
* Aghanim's Scepter upgraded Eclipse combined with Dust of Appearance allows Luna to cast it on a hero that is struck by Sacred Arrow and/or after Mirana jumps in with Leap.
Mirana
* A couple of long-range heroes with excellent laning like Mirana, Lina, 
Necrophos, Death Prophet. The key to success is sticking together and attacking Luna whenever she enters the range, without even giving Luna a chance to retaliate. Multiple long-range heroes is a reason to pick another hero.
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.
Mirana

Mirana
* Heroes that cannot move in fights such as a Dueling Legion Commander or anyone channeling a spell like Bane, Pudge, or Enigma are easy Sacred Arrow targets.
Mirana
* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.
Additional:
* All abilities from Mirana can shut down with 
Doom and Mirana can not escape with Leap since Doom activated.
* Doom also catch Mirana disabled used combo items Doom from ugrade Aghanim's Scepter and Blink Dagger or 
Overwhelming Blink make Mirana can not move escaping notably Leap and Moonlight Shadow.
Mars
* Heroes who can disable Mars but cannot do any damage to him, meaning he just tanks their abilities: Doom, Magnus.
Mirana
* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.
Mirana
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like Mirana's Sacred Arrow or 
Leshrac's 
Split Earth, or combos like Kunkka's 
X Marks the Spot into Torrent.
Mirana
* If Slark sees the Sacred Arrow before it hits him, he can use 
Dark Pact to remove it a moment later.
* 
Pounce prevents Mirana from escaping with Leap.
* Slark can survive Mirana's Aghanim's Scepter combo with 
Shadow Dance.
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.
Mirana
