Sand King
* 
Zeus usually stays at the back in teamfights and it is hard for Sand King to find Zeus and knock him down before Zeus deals his damage.
* All of Zeus' abilities, especially 
Thundergod's Wrath, disables Sand King's 
Blink Dagger, effectively reducing Sand King's initiation and counter-initiation potential.
* 
Lightning Bolt deals damage to Sand King in Sand Storm and reveals him. It also interrupts channeling of Epicenter.
Magnus
* Zeus can easily find Magnus who is often hiding in the trees with Thundergod's Wrath and Lightning Bolt, which allows him to warn allies and disrupt his initiation attempts.
Sand King
* Burrowstrike is one of the best and easiest steals for Rubick and Sand King should be careful when playing against him - it's much better to give away Sand Storm.
Magnus
* All of Magnus's spells are perfect for Rubick to steal, especially Reverse Polarity for a counter-initiation.
* 
Telekinesis is one of the best instant-disables in the game, completely ruining Magnus's initiation.
Additional:
* 
Reverse Polarity, if stolen, can counter-initiate 
Magnus's team and put them at a huge disadvantage.
* Magnus himself is positioned at the center of teamfight after casting Reverse Polarity, and will be stunned by Rubick's stolen one most of the times.
* Bear in mind that Magnus will usually cass 
Skewer or 
Shockwave after he casts the ultimate, so the time windows left for steal can be short.
* Shockwave allows Rubick to farm fast, and also deals decent AoE damage in teamfights.
* 
Empower can be casted on the carry (especially affective if melee) on Rubick's team to accelerate their farm or amplify their damage in fights.
* Skewer could be used to displace enemy or escape from danger.
* Telekinesis can relocate the enemy in front of Rubick for Skewer.
* With Quick Cast enabled, Rubick can stop the enemy Magnus with careful prediction using Telekinesis to interrupt 
Horn Toss - Skewer combo.
Sand King
* Ghostship helps your team soak up damage from 
Epicenter, especially if he initiates during the battle.
* 
Sand King can't dodge X Marks the Spot - Torrent combo by his abilities. Torrent drags him out of his 
Sand Storm
Magnus
* 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.
Sand King
* 
Ravage, being an AoE disable, cancels Epicenter's channeling from a long range, limiting his potential to counter-initiate.
* This can be remedied, however, by first using a 
Black King Bar, then channel Epicenter, then finally initiate with Blink Dagger.
Magnus
* 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.
Magnus
* Treant Protector can usually scout out Magnus in the trees with 
Eyes in the Forest and disrupt his initiation attempts. He can also counter Magnus' initiation with 
Overgrowth.
Magnus
* Tinker can break Magnus's Blink Dagger using 
March of the Machines and 
Heat-Seeking Missile, therefore delaying any initiation or making Magnus use Skewer or 
Force Staff to initiate. His {Ability ID:Defense Matrix|Tinker} will decrease the duration of Reverse Polarity and can also be cast on all of his teammates with {Ability ID:Rearm|Tinker}. Tinker usually gets his own Blink Dagger as well, which makes him harder to lock down unless Magnus commits Reverse Polarity only for Tinker.
Magnus
* 
Rupture deals extra damage to Magnus during Skewer or Force Staff, preventing him from escaping or counter-initiating, forcing him to invest on a 
Linken's Sphere.
Magnus
* Even if Wraith King dies after Magnus disables him, Magnus' entire team will be slowed and vulnerable for counter-initiation.
Sand King
* Both 
Arcane Curse and 
Last Word punishes casters with spammable spells such as Sand King.
* As a strength caster, 
Intelligence Steal reduces Sand King's mana pool even more.
* 
Global Silence silences Sand King, effectively reducing Sand King's initiation and counter-initiation potential. It can also interrupt channeling of Epicenter.
Sand King
* 
Boulder Smash will push Sand King out of Sand Storm to reveal his position or an activated Epicenter off of Earth Spirit's allies, potentially wasting his combo
* 
Rolling Boulder and 
Geomagnetic Grip allow Earth Spirit to easily stun and silence Sand King and interrupt the channeling of Epicenter, completely ruining his initiation.
Magnus
* Magnus cannot manfight Huskar even with Empower, 
Berserker's Blood's high attack speed and health regeneration, combined with Huskar's high health and 
Burning Spear stacks will allow Huskar to kill Magnus before he can kill him.
* From a safe distance, Huskar can surprise and counter Magnus's initiation with 
Life Break and Burning Spear.
* Burning Spear also deals damage over time, disabling Blink Dagger and preventing him from initiating or escaping.
Magnus
* Magnus has very mediocre damage against Alchemist, because he can survive the stun duration of Reverse Polarity with 
Chemical Rage.
Magnus
* Similar to Night Stalker, Venomancer can simultaneously scout Magnus hiding in trees and put Blink Dagger on cooldown with 
Plague Ward, which gives Magnus problems when trying to blink in and initiate.
Additional:
* Venomancer can simultaneously scout Magnus hiding in trees and putting Blink Dagger on cooldown with Plague Wards, which makes Magnus real problems to blink and initiate.
Magnus
* Spectre disables Magnus' Blink Dagger using her ultimate, and later into the game can usually outlive Reverse Polarity's duration.
Additional:
* Spectre can use 
Haunt to intercept and disrupt Magnus's initiation attempts.
* 
Spectral Dagger can severely slow down Magnus after he uses Skewer.
* Magnus often travels alone when he is trying to initiate, so 
Desolate can be very effective against him.
* In late game, Spectre can survive Reverse Polarity initiation thanks to 
Dispersion.
Magnus
* Disruptor can disable Magnus's Blink Dagger using 
Thunder Strike during a considerable duration, disrupting his initiation attempts.
* 
Glimpse brings Magnus back after he escapes with Skewer and/or Force Staff.
* 
Static Storm if used on a fight can prevent Magnus from using Reverse Polarity after he jumps in.
Magnus
* 
Illusory Orb serves as a good scouting tool whenever Magnus is hiding in the trees, allowing Puck to warn its allies and disrupt his initiation attempts.
* 
Phase Shift allows Puck to dodge Shockwave when timed correctly.
* Even after Magnus successfully uses Reverse Polarity and Skewer Puck's teammates, Puck can usually counter-initiate using both 
Waning Rift and 
Dream Coil.
* Magnus cannot use Skewer when he is affected by Dream Coil, making him vulnerable to follow-up disables.
* Puck usually gets its own Blink Dagger as well, which makes it harder to lock down unless Magnus commits Reverse Polarity only for Puck.
Magnus
* 
Plasma Field can slow Magnus during Skewer, and when combined with 
Eye of the Storm, will potentially disable his Blink Dagger, preventing him from initiating.
* 
Static Link drains the bonus damage from Empower. However, it can be broken by Skewer and/or Force Staff.
* 
Storm Surge gives Razor and his allies high mobility needed to avoid Shockwave & Reverse Polarity.
Magnus
* Magnus is not tanky and struggles against burst damage, something Primal Beast excels at in the early-to-mid game. Primal Beast is also able to out-damage Magnus's Empower and can even contribute to his Uproar stacks.
* Using Skewer to drag Primal Beast while he is trampling will count as movement and will trigger a rapid number of slams, which could prove lethal to Magnus.
Sand King
* Quill Spray will hit Sand King inside Sand Storm, damaging him and putting Sand King's Blink Dagger on cooldown, preventing him from escaping.
* Epicenter's numerous damage ticks will trigger Bristleback's passive repeatedly during teamfights.
Magnus
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, 
Weaver, 
Abaddon, 
Troll Warlord, Alchemist, 
Dragon Knight, 
Night Stalker, 
Viper.

Magnus
* Heroes who take a long time to become strong are in for a rough mid game, such as 
Outworld Destroyer, Magnus, Medusa, and 
Anti-Mage.

Magnus
* 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,

Magnus
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.
Additional:
* Most of Magnus's abilities except Empower will trigger damage through 
Corrosive Skin.
* 
Poison Attack and 
Viper Strike can slow Magnus during Skewer, as well as putting his Blink Dagger on cooldown, preventing him from initiating or re-initiating.
Magnus
* Heroes that have high health but little to no magic resistance are easy prey for Necrophos, as no matter how high they build their health up, Reaper's Scythe will kill them outright as long as they fall under a certain threshold, and Heartstopper Aura will deal the same amount of damage regardless, decaying their health the longer they stay within range. As such, Strength heroes like 
Chaos Knight, 
Centaur Warrunner or Magnus are good targets for his ultimate.
Magnus
* 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.

Sand King
* Pugna's 
Nether Ward damages Sand King when he channels Epicenter, preventing him from using Blink Dagger afterward.
Magnus
* 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.
Sand King
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, Jakiro, Pugna, 
Earthshaker.
Magnus
* Any hero who can survive Magnus's initiations and manfight him: Huskar, Faceless Void, Weaver, Abaddon, Troll Warlord, Alchemist, Dragon Knight, Night Stalker, Viper.
Magnus
* Heroes who build mana boosting items but have low mana regeneration are especially vulnerable against Mana Break and Mana Void: 
Timbersaw, 
Slark, Shadow Fiend, 
Clinkz, 
Bristleback 
Nyx Assassin, Magnus
Additional:
* Anti-Mage can survive against Magnus's Reverse Polarity thanks to the high magic resistance from 
Counterspell.
* Should Anti-Mage survive Magnus's Reverse Polarity and Skewer, Magnus will have exhausted most of his skills and items, preventing him from defending himself against any counter initiation or a follow-up from a blink escape.
* 
Mana Break can deplete Magnus's much needed mana.
* Anti-Mage's 
Blink will make him a very hard target or Magnus to use Reverse Polarity on, having to solo ult him later on in the game or leave him out of the Reverse Polarity.
* Overall, any attempt for Magnus to gank Anti-Mage will hurt him more than it will hurt Anti-Mage.
Magnus
* 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.

Magnus
* 
Dark Ascension reduces vision for the enemy team, which makes it more difficult for Magnus to initiate with Blink Dagger and Reverse Polarity. It is also more likely that Night Stalker will scout out Magnus with 
Aghanim's Scepter and a 
Gem of True Sight, after which he can silence Magnus with 
Crippling Fear.
Sand King
* Heroes that rely on slows to get kills: 
Lifestealer, Night Stalker, 
Ursa, 
Phantom Assassin, 
Terrorblade.
Magnus
* Jakiro's abilities deal damage over time, which can disrupt Magnus's attempts to initiate with Blink Dagger and Reverse Polarity.
* 
Macropyre not only disables Blink Dagger for a considerable duration, but can also destroy Trees, revealing Magnus's cover and position.
Sand King
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, Jakiro, Pugna, Earthshaker.
Sand King
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, 
Earth Spirit, Faceless Void, Magnus, 
Mirana, 
Monkey King,

Sand King
* Slark will have a hard time killing Sand King because of the survivability he gets from Burrowstrike and Sand Storm.
* 
Shadow Dance, which usually allows Slark to survive fights, is ineffective against Sand King's AoE damage.
Sand King
* All of Sand King's abilities deal AoE damage.
* However, Epicenter is usually a non-issue against Doppelganger.
Magnus
* Empower helps Magnus' allies clear out illusions.
* Reverse Polarity and Skewer will pull Phantom Lancer along with his illusions, and reposition them together for easy nuking.
* Shockwave deals significant area damage in the early game,destroys phantoms and may even indicate the real Phantom Lancer.
Sand King
* Sand King's massive area damage output, particularly Epicenter, allows him to quickly take down Chaos Knight and his illusions.
* Sand King can also apply 
Caustic Finale to illusions with attacks for extra damage when they die.
Magnus
* Using Reality Rift sets up a Reverse Polarity on Chaos Knight and his illusions.
* Shockwave and Skewer kill Phantasm's illusions quickly, as can Empower cast on a melee carry.
Additional:
* All Magnus abilities are very good against Chaos Knight's 
Phantasm illusions.
Sand King
* 
Burrowstrike, Sand Storm, Caustic Finale and Epicenter will deal a large amount of damage to Chen and his creeps.
Magnus
* Heroes with strong area-of-effect damage can make quick work of Chen's converted creeps and at same time gain farm: Magnus, Jakiro, Shadow Fiend, Kunkka, Luna, Dragon Knight, Medusa, Alchemist.
Sand King
* Sand King's Caustic Finale combined with Sand Storm will kill Treants easily.
* Sand King can interrupt Teleportation with Burrowstrike, even through Sprout.
Additional:
* With Caustic Finale, Sand King can easily kill the treants from 
Nature's Call.
* Burrowstrike allows Sand King to prevent Nature's Prophet from using 
Teleportation inside of his 
Sprout.
Magnus
* Heroes who rely on illusions and spawns (Chaos Knight, 
Beastmaster, 
Nature's Prophet, Enigma etc.).
Sand King
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.
Additional:
* Burrowstrike can stun multiple Meepos, making them vulnerable targets.
* Epicenter and Sand Storm's AoE damage ensures all Meepo clones get damaged, making it hard for Meepo to choose which one to flee as all are taking damage at the same rate.
* Just be aware when using Sand Storm to escape, as Meepo has good AoE damage and disables, which, as explained in the "Bad Against" section, works well against an invisible Sand King.
Magnus
* Meepo is vulnerable to area damage and disables from Magnus himself as well as his team through Empower.
Sand King
* Sand King's Sand Storm damages familiars quickly whittling them down in health, rendering them vulnerable.
* Sand King's Epicenter quickly damages and destroys familiars.
Magnus
* Heroes with cleave or multi-target attacks can quickly take on Familiars and reduce Visage's firepower like 
Gyrocopter, Kunkka, Magnus and Medusa.
Sand King
* 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

Magnus
* Skewer and Reverse Polarity will often push Monkey King out of Wukong's Command.
Sand King
* Sand King can quickly remove her 
Refraction with his Sand Storm.
* Once Refraction is down, she is very vulnerable to Epicenter's high magic damage.
Sand King
* Phantom Assassin relies on her 
Blur to stay alive, but is very vulnerable to Sand King's heavy magic damage.
* With Burrowstrike, Sand King can often catch Phantom Assassin before she can use her Black King Bar.
* Sand King can dodge 
Stifling Dagger with Sandstorm.
* Phantom Assassin has a hard time killing Sand King because of his high mobility.
Sand King
* Lifestealer's Rage negates Sand King's spells which do magical damage.
Sand King
* Heroes that rely on slows to get kills: Lifestealer, Night Stalker, Ursa, Phantom Assassin, Terrorblade.
Magnus
* Reverse Polarity pierces through 
Rage, wasting part of it's duration.
* Magnus is tanky and mobile, making it hard for Lifestealer to focus and kill him in all stages of a game.
Magnus
* Any long duration disables that can pierce through both, Pierce The Veil and Black King Bar are devastating against Muerta: Enigma's Black Hole, Dawnbreaker's Solar Guardian, Axe's Berserker's Call, Naga Siren's Aghanim's Scepter upgraded 
Ensnare and

Magnus
* Heroes with forced movement abilities or non-interrupting forced movement, such as 
Lion,

Sand King
* Heroes that rely on slows to get kills: Lifestealer, Night Stalker, Ursa, Phantom Assassin, Terrorblade.
Magnus
* Heroes with AoE abilities are a bane to Beastmaster's summons: 
Storm Spirit, Magnus, Pangolier.
Magnus
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, Beastmaster, Enigma, Magnus, Pudge, Batrider, Bane, Winter Wyvern
Magnus
* 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.
Sand King
* Since Naga Siren is a hero who barely goes for Black King Bar, she is vulnerable to nukers with strong magical damage and big area-of-effect spells in every game more than any other carry heroes: Sand King, Jakiro, 
Leshrac, Lina, Earthshaker, Zeus.
Magnus
* Heroes whose attacks can affect multiple enemies at once will clear Naga Siren's illusions. Such heroes include Sven, Magnus, Dragon Knight, Luna, Medusa, 
Templar Assassin, Gyrocopter, Muerta.
Sand King
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, Jakiro, Pugna, Earthshaker.
Magnus
* Squishy core heroes (Shadow Fiend, 
Sniper, etc)
Sand King
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, 
Enchantress.
Sand King
* Heroes that rely on slows to get kills: Lifestealer, Night Stalker, Ursa, Phantom Assassin, Terrorblade.
Sand King
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, Viper, Venomancer, Huskar, Ember Spirit, Dark Seer, Sand King, 
Doom, Dawnbreaker. However, this also means they are easily stunned.
Magnus
* With Aghanim's Scepter, Broodmother will gain access to Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: Phantom Assassin, Nyx Assassin, Mirana, 
Bounty Hunter, Templar Assassin, Riki, Spirit Breaker, Anti-Mage, Tusk, Ursa, Nature's Prophet, Enigma, 
Void Spirit, Magnus etc.
Sand King
* Burrowstrike can be used as an escape or initiation against Broodmother.
* Sand Storm quickly kills any spiderlings caught inside if Sand King can manage to stun them.
Additional:
* Caustic Finale allows Sand King to easily kill Broodmother's Spiderlings throughout the game.
* Sand King can usually catch a split pushing Broodmother with Blink Dagger and Burrowstrike.
Magnus
* 
Shrapnel can sometimes scout out Magnus and also place his Blink Dagger on cooldown. Aside from that, Sniper likes to stay far back behind enemy lines, so it's difficult to catch him with Reverse Polarity unless you already have vision on him and can Skewer him to the rest of his team.
Sand King
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, Clinkz, Sniper, Enchantress.

Magnus
* If Luna can use Eclipse in anticipation, Magnus will be killed before he can even manages to cast Reverse Polarity.
* Aghanim's Scepter upgraded Eclipse is a very good counter-initiation tool against Magnus when he casts Reverse Polarity, granted as long as Luna can cast it from safe distance.
Sand King
* Burrowstrike allows Sand King to escape from Eclipse or to close the gap on Luna and finish her off.
* Sand Storm allows Sand King to harass Luna more efficiently than she does with 
Lucent Beam, as it makes him invisible for it's duration and while in it, rendering him safe from both, Lucent Beam and Eclipse and forcing Luna to buy 
Dust of Appearance more often.
* Caustic Finale allows Sand King to deal serious damage to both, Luna and her allies, which is especially hazardous in laning stage as Luna's attack range is short.
* Epicenter combined with Burrowstrike and Sand Storm can often kill Luna before she can do anything because of her low health and strength gain.
* Overall, Sand King forces Luna to play more defensively instead of offensively, and for the same reasons, Sand King makes a very powerful ally for Luna when they are in the same team.

Sand King
* Sand King has nothing to deal with
Supernova, as none of his spells are effective.
Blink Dagger very often.
* The damage-over-time abilities of Phoenix disable Sand King's
Magnus
* Phoenix will usually be on the sidelines or further back ready to use
Sun Ray. Even after Magnus successfully uses Reverse Polarity and skewer Phoenix's teammates, Phoenix can usually counter-initiate using all of its abilities.
