Enchantress
* Heroes with nukes that can jump her: 
Clockwerk, 
Snapfire, 
Spirit Breaker, 
Techies
Elder Titan
* 
Battery Assault's continuous mini-stun makes it hard for Elder Titan to cast his spells due to his poor cast animation.
* Elder Titan's channelling with Echo Stomp makes a good setup for 
Hookshot if timed correctly.
Enchantress
* Heroes with nukes: 
Bane, 
Lich, 
Lion, 
Skywrath Mage
Elder Titan
* 
Frost Shield helps offset the armor reduction from Natural Order.
Enchantress
* 
Enchant can not control golem 
Chaotic Offering from Warlock.
Elder Titan
* While heroes with strong mobility are able to get close or flee from Upheaval, heroes with no escaping abilities or that lack long disables will perish against Warlock. Once the Warlock Golem lands with its stun, its hardly possible to escape when he casts Upheaval. Notable examples: 
Huskar, 
Drow Ranger, Lion, 
Elder Titan, etc.
Enchantress
* Heroes that can jump on her: 
Slark, 
Queen of Pain, 
Anti-Mage
Elder Titan
* 
Echo Stomp and 
Earth Splitter's long cast times give Anti-Mage plenty of time to Blink away.
Enchantress
* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Additional:
* 
Enchantress is very fragile without any form of magic resistance, allowing Lion to easily burst her down.
* 
Nature's Attendants is a slow heal, making not as much effective against Lion's burst as it could be.
* Her raw movement speed is a fair escape/mobility mechanism, which may allow her to avoid a blindly cast 
Earth Spike, but does nothing against the rest of Lion's abilities, since they are single target and can't miss.
* Since Lion's damage comes mostly from his skills, 
Untouchable does nothing to mitigate it.
Elder Titan
* With a lot of disables with good range, he might cancel your Echo Stomp.
* 
Mana Drain can be used to drain Elder Titan's already low mana pool.
Enchantress
* 
Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time: 
Phantom Assassin, Enchantress, Huskar, 
Underlord.
Additional:
* 
Devour can easily eat creeps controlled by Enchant, limiting her ganking potential.
* Doom reduces the amount of healing received by Enchantress and her allies from Nature's Attendants. In addition, when Doom chooses the Doom applies Break talent, it can also disable Untouchable.
Elder Titan
* Infernal Blade deals scaling damage and is useful against high HP targets such as Elder Titan. It also can interrupt Echo Stomp if quick enough.
* Doom has very low base armor and naturally high HP, so he isn't significantly affected by 
Natural Order.
Enchantress
* All of Tinker's damage is magic/pure and completely ignores Enchantress's Untouchable. And Tinker's nukes can quickly decimate her small HP pool, sometimes even preventing Enchantress from even responding.
* As Enchantress relies solely on her primary attacks to deal damage, and rarely builds something to dispel it, Laser's Blind is particularly effective.
* However, Enchantress will probably build a Linken's Sphere against Tinker's Laser, so getting an additional disable is highly recommended.
Enchantress
* Enchantress often has a small army of neutral creeps, allowing Medusa to hit her with a later bounce of her Mystic Snake.
Enchantress
* Enchantress has a very low health pool, allowing Zeus to burst her down quickly before she can heal off the damage with Nature's Attendants.
* Zeus will not be affected by Untouchable, as he won't try to attack her with right clicks anyway.
* Zeus can stay out of her attack range while trying to kill her, especially if he has bought an 
Aether Lens.
* Most heroes would want to get on top of Zeus to kill him, but Enchantress does not have this option as doing so would severely limit her damage from Impetus.
* The exception is the laning phase, where Enchantress can gank Zeus if she Enchants a good creep.
Additional:
* Enchantress has a very low health pool, allowing Zeus to burst her down quickly before she can heal off the damage.
* Zeus will not be affected by Untouchable, as he won't try to attack her with right clicks anyway.
* Zeus can stay out of her attack range while trying to kill her, especially if he has bought an Aether Lens.
* Most heroes would want to get on top of Zeus to kill him, but Enchantress does not have this option as doing so would severely limit her 
Impetus damage.
* The exception is the laning phase, where Enchantress can gank Zeus if she Enchants a good creep.
Enchantress
* Amazingly, Enchantress has even lower health than Pugna. Though she does pack quite a punch through Impetus, she can't use it if she is under Decrepify.
* Pugna's Magical DPS is way greater than the heal from Nature's Attendants, which will also harm her quite a bit if she's next to Nether Ward.
Elder Titan
* All of his spells can stun Elder Titan and interrupt Echo Stomp's channeling thanks to 
Aftershock.
* 
Fissure is particularly good for that purpose thanks to its long range.
* Elder Titan relies heavily on his spells and a chain-stun combo will usually be followed by certain death.
Enchantress
* 
Vendetta can deal great damage against her. However, it requires an direct attack, so Nyx Assassin may have difficulties applying Vendetta on her.
* Enchantress's lack of mobility makes her a primary target for ganking with Vendetta.
* 
Mind Flare can deal a great damage against her due to being an Intelligence hero.
* 
Spiked Carapace can reflect Impetus and stun Enchantress.
Additional:
* Spiked Carapace reflects the damage from Impetus.
* Enchantress is a rather squishy hero, making her fall easily to Nyx Assassin's high burst damage.
Enchantress
* Riki usually buys 
Diffusal Blade to initiate, which renders Enchantress' movement speed useless, and is usually followed with 
Smoke Screen.
* Riki can effectively hit Enchantress by 
Tricks of the Trade alongside with Diffusal Blade and Smoke Screen's initiation. For a hero like Enchantress, 3 to 4 hits from Riki is a big deal, unless Enchantress built 
Force Staff earlier.
Enchantress
* 
Battle Trance and 
Fervor can help Troll Warlord deal with Enchantress through Untouchable.
Additional:
* Untouchable's attack speed slow is easily remedied by Fervor stacks and Battle Trance.
* Troll Warlord is a natural 
Silver Edge carrier, disabling Enchantress' Untouchable.
Enchantress
* Untouchable won't mitigate Venomancer's magical damage, and Enchantress is vulnerable to magic damage.
* Both 
Venomous Gale and 
Poison Nova lower the amount of healing received by Enchantress and her allies from Nature's Attendants.
Elder Titan
* {U:Earth} has passive 
Spell Immunity, allowing him to walk into the Echo Stomp radius to stun Elder Titan with his 
Hurl Boulder.
* {U:Storm}'s 
Cyclone can cancel the channeling of Echo Stomp and take Elder Titan out of the fight for {show:A|Storm|Cyclone|value2} seconds.
Enchantress
* Enchantress has a very small health pool and cannot tank Lina's heavy magic burst.
* Untouchable is decently countered by 
Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress's creeps quickly.
Additional:
* Enchantress has pitiful health, and cannot tank Lina's heavy magic damage.
* Untouchable is decently countered by Fiery Soul, exposing Enchantress's weakness to physical damage due to her low armor.
* Lina is decent at clearing creeps and can kill Enchantress' creeps quickly.
Enchantress
* Magnetic Field makes Impetus miss; if Enchantress decides to enter the field, she is giving up bonus damage since Impetus deals greater damage at higher distance away from targets.
Enchantress
* Untouchable doesn't work against Unleash, as Marci gains 1000+ attack speed for the fury combo.
* Enchantress' low health makes her a fragile target for Marci's damage blasts.
* Marci can use Rebound on one of her enchanted creeps to easily reach the Enchantress and negate the bonus damage dealt by her Impetus. It helps that most of her best creeps have a low attack range, creating a makeshift bridge towards their master.
Enchantress
* 
Windrun's speed allows easy pursuit or escape, while the evasion greatly reduces the threat of Enchantress's Impetus, especially when retreating.
* 
Shackleshot is a powerful disable if Enchantress gets too close to one of her own minions.
* 
Focus Fire can negate Untouchable.
Enchantress
* Heroes with haste can negate Enchant's slow: 
Weaver, 
Dark Seer, 
Lycan, 
Centaur Warrunner.
Enchantress
* Heroes with break can disable Untouchable for a while: 
Doom and 
Shadow Demon (via 
Aghanim's Scepter), 
Viper, 
Shadow Shaman with Hex Breaks talent.
Enchantress
* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Enchantress
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.
Enchantress
* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper, Shadow Shaman with Hex Breaks talent.
Enchantress
* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage
Additional:
* Queen of Pain often relies more on abilities than right-clicks, making Untouchable nearly useless against her.
* Enchantress also has a lower health pool than Queen of Pain, making her vulnerable to Queen of Pain's damage burst.
Enchantress
* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies
Enchantress
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.
Enchantress
* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Additional:
* Untouchable is useless versus constant Arcane Bolts, and it doesn't help that her strength gain is the lowest in the game.
* A jungle Enchantress can weaken lanes and make Skywrath Mage's job easier.
* The magic amplification from Ancient Seal makes her even squishier to Skywrath and his allies' magic nukes.
Enchantress
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: Phantom Assassin, 
Clinkz, 
Sniper, Enchantress.
Enchantress
* Enchantress has pitiful HP, even more pitiful than Luna, so 
Lucent Beam and 
Eclipse will often harass and/or kill her through her Untouchable.
* With 
Moon Glaives, Luna can clear Enchantress's creep wave efficiently.
Additional:
* Though Enchantress's Untouchable can greatly reduce Luna's attack speed, and can go through any form of Spell Immunity, she has a pitiful HP so Lucent Beam and Eclipse can kill her very quickly.
* Moon Glaives allows Luna to clear Enchantress's creeps very efficiently.
Enchantress
* Heroes that create illusions: 
Spectre, Shadow Demon, 
Phantom Lancer, 
Naga Siren, 
Chaos Knight, 
Terrorblade) or bring other units into the fight (such as 
Nature's Prophet, 
Lone Druid, 
Chen, Enchantress, 
Meepo and 
Arc Warden) can cause Eclipse to strike the illusions/summons unintentionally. However, in many cases Moon Glaives can resolve this issue and eliminate them before activating Eclipse, but that will require lots of farming for right-click items.
Enchantress
* The burst damage from Timbersaw's abilities is more than enough to deal with Enchantress and her creeps.
* Timbersaw doesn't rely on his physical attacks, which makes Untouchable useless against him.
* 
Timber Chain can close the gap between them and minimize damage from Impetus.
* Bear in mind, however, that Timber Chain can also work against Timbersaw if used to escape and that Impetus can ignore 
Reactive Armor if Enchantress is not a primary target for Timbersaw or if he is disabled.
* Timbersaw is a common wielder of 
Lotus Orb, which will allow him to reflect Enchant back at Enchantress and dispel most debuffs as well.
Enchantress
* Timbersaw has a difficult time against magical and pure damage: 
Lina, 
Leshrac, Enchantress, Queen of Pain
Enchantress
* Enchantress can turn Chen's own creeps against him with Enchant. The creeps still keep the health buff Holy Persuasion granted them. 
Aghanim's Shard gives Enchantress 
Little Friends ability, which allows her to turn multiple of Chen's creeps all at once against him.
* Untouchable and Nature's Attendants make her difficult to kill.
Additional:
* Even though Chen can use 
Holy Persuasion on creeps controlled by Enchant, Enchantress can also use Enchant on Chen's creeps, making it somewhat of a double-edged sword type of matchup.
* Aghanim's Shard gives Enchantress Little Friends ability, which she can use to turn all of Chen's creeps against him for a short time when casted on him.
* Impetus's high burst damage can often kill any of Chen's allies before he can save them with 
Hand of God.
Elder Titan
* Elder Titan's 
Astral Spirit ability gives him bonus damage for each converted creep it passes through.
* Echo Stomp and Earth Splitter will often kill him or any of his allies quickly before he has time to use Hand of God.
Enchantress
* Heroes that can dominate his illusions or create their own illusions of him: Dark Seer, 
Morphling, Enchantress, Shadow Demon, 
Grimstroke with Aghanim's Scepter.
Elder Titan
* Terrorblade has a high base armor, and relies on many ultimate orb-based items (
Manta Style and 
Eye of Skadi). Natural Order affects armor gained from agility, essentially reducing armor to zero if all armor is gained from agility. That effect combined with Terrorblade's low health can make a Elder Titan with an early value point in Natural Order a dangerous foe.
* Terrorblade's illusions are often grouped up in teamfight, making them more vulnerable to Echo Stomp.
Additional:
* Echo Stomp and Astral Spirit allow Elder Titan and his team to coordinate a kill on Terrorblade before he can use 
Sunder.
* Natural Order cripples Terrorblade's armor that he crucially needs to survive due to his low strength gain. This is very detrimental for Terrorblade as he is prone to buying items that require 
Ultimate Orb like Manta Style and Eye of Skadi.
* Echo Stomp and Earth Splitter will often kill Terrorblade before he can use Sunder, and will also kill his illusions.
Enchantress
* Heroes that have an escape that doesn't disjoint projectiles: 
Mirana, 
Faceless Void, 
Magnus
Elder Titan
* 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.
Elder Titan
* Phantom Lancer's lack of disables makes it hard for him to stop Echo Stomp's channelling.
* However, due to the long cast time of his abilities, a good Phantom Lancer can use Manta Style and/or 
Doppelganger to dodge the abilities.
* Phantom Lancer's high agility and relatively low strength make him very vulnerable to Natural Order.
* Additionally, Echo Stomp and Earth Splitter can clear his wave of illusions.
* Should Phantom Lancer tries to increase his health by investing for 
Heart of Tarrasque, Earth Splitter does more damage to him and his illusions.
Elder Titan
* Morphling's high armor is primarily from morphing agility, which is reduced by Natural Order therefore making the hero very vulnerable when it has morphed a lot into agility.
* Morphling usually will Morph into high agility and low strength. This can be taken advantage of with a good stun or silence or by bursting him down before he has the time to Morph back to strength.
* Morphling is very vulnerable to 
Blade Mail under Natural Order and can easily burst himself down with his own auto-attacks or his magical damage combo.
Additional:
* Most of Morphling's armor comes from his high agility and it is reduced by Natural Order.
* However, the aura has only 350 range and Elder Titan can be bursted down by Morphling's nuke combo if he isn't careful.
Enchantress
* Untouchable will significantly slow down Chaos Knight's physical damage with Phantasm.
* Impetus deals double damage to illusions, making it effective against Phantasm.
Additional:
* Untouchable makes all of Chaos Knight's attacks slow therefore he is unable to deal damage, especially his critical damage of 
Chaos Strike, also enables Enchantress to escape easily from his attacks.
* However, 
Reality Rift can still pose a danger to Enchantress because Chaos Knight can decrease a good amount of armor, making it dangerous because of her little armor stat, as he can burst down Enchantress easily if any of Chaos Knight's allies can apply a break on Enchantress.
Enchantress
* Impetus pure damage ignores the extra armor granted from Wukong's Command.
* Enchant can dispel Monkey King's Jingu Mastery bonuses.
* Untouchable makes it hard for Monkey King to land Jingu Mastery stacks.
* 
Sproink allows Enchantress to escape from Wukong's Command.
Enchantress
* Untouchable negates Inner Beast's attack speed bonus, making her hard to kill even if stunned by Primal Roar.
* Enchantress can also take control of Beastmaster's summons.
Additional:
* Enchant can control Beastmaster's boars with Enchant, mitigating his effectiveness during the laning stage and teamfights.
Enchantress
* Untouchable prevents Clinkz from harassing Enchantress in lane by lowering his attack speed.
* Nature's Attendants helps Enchantress to sustain through Clinkz's harassment in lane.
Elder Titan
* Astral Spirit can give Elder Titan a lot of damage and movement speed if Nature's Prophet sends all of his Treants together.
* Not only does Echo Stomp prevent Nature's Prophet from escaping using Teleportation, but Astral Spirit can be used to bypass Sprout and cancel Teleportation with it's own Echo Stomp from long distances.
* Earth Splitter can clear Nature's Prophet's Treants effectively.
Enchantress
* Untouchable greatly reduces Chemical Rage's attack speed advantage.
Enchantress
* Impetus will deal huge amounts of damage when he uses a 
Fire Remnant to escape.
* 
Flame Guard is useless against Impetus as it deals Pure damage.
* Enchant can be used to dispel Flame Guard.
Enchantress
* Impetus is not blocked by 
Guardian Angel. A {U:Satyr Banisher} can also be controlled to dispel Guardian Angel.
Additional:
* Enchantress's Impetus deals pure damage instead of physical damage and ignores Guardian Angel, thus fully negating one of Omniknight's most important abilities for teamfights.
* Similar to Doom, Enchantress can use Enchant on Satyr Banisher, which will give her access to Satyr Banisher's 
Purge, and allow her to remove Heavenly Grace and Guardian Angel.
Enchantress
* Untouchable makes Enchantress one of the hardest heroes for Legion Commander to Duel against, as her attack speed will be significantly slowed for the duration, even with any form of spell immunity.
* Meanwhile, when Enchantress is not a target, Enchantress can use both Impetus and Enchant on Legion Commander to help her ally win the Duel.
Enchantress
* Enchant can dispel 
Overpower.
* Enchant's slow can help kite Ursa in fights and also in lane.
* Enchantress can out harass Ursa in lane by using her long attack range and Untouchable, as well as out sustaining him with Nature's Attendants.
Enchantress
* Untouchable makes it near impossible to stack Burning Spears.
* Impetus' pure damage puts an instant end to Huskar's low-health brinkmanship.
Enchantress
* Since Untouchable pierces Spell Immunity, Lifestealer cannot burst her down even with 
Rage; meaning she can heal herself back to full HP.
Elder Titan
* Heroes with AoE nukes will clear her illusions in no time, especially if they are percentage-damage-based, like Underlord's 
Firestorm, Elder Titan's Earth Splitter, Enigma's 
Midnight Pulse, Zeus's 
Arc Lightning, Jakiro's 
Liquid Frost from Aghanim's Shard etc.
Enchantress
* Range-reliant heroes: Sniper, Drow Ranger
Elder Titan
* 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 
Berserker's Call, Mars's 
Arena of Blood, Jakiro's 
Macropyre, 
Dual Breath and 
Ice Path, Naga Siren's 
Song of the Siren, Razor's 
Eye of the Storm and 
Plasma Field, Lina's 
Light Strike Array, 
Broodmother's 
Spinner's Snare from Aghanim's Scepter, Elder Titan's Earth Splitter and Echo Stomp, Alchemist's 
Unstable Concoction and 
Acid Spray, Queen of Pain's 
Sonic Wave, Dark Seer's 
Wall of Replica and 
Vacuum, Venomancer's 
Noxious Plague and Poison Nova from Aghanim's Scepter, Oracle's 
Fortune's End and 
Rain of Destiny from Aghanim's Shard, 
Bloodseeker's 
Blood Rite, Enigma's 
Black Hole and Midnight Pulse, 
Shadow Fiend's 
Requiem of Souls, Batrider's Aghanim's Scepter upgraded 
Flaming Lasso, 
Firefly, 
Flamebreak and 
Sticky Napalm, 
Ancient Apparition's 
Ice Blast, Sand King's 
Epicenter, 
Sand Storm and 
Burrowstrike, 
Gyrocopter's 
Call Down, 
Ember Spirit's 
Sleight of Fist, 
Death Prophet's 
Exorcism and 
Silence, 
Monkey King's 
Wukong's Command, 
Crystal Maiden's

Muerta's 
The Calling, Medusa's 
Stone Gaze, Zeus's 
Nimbus from Aghanim's Scepter. 
Dark Willow's 
Bramble Maze, 
Pangolier's 
Swashbuckle, Grimstroke's 
Soulbind, 
Ink Swell and 
Stroke of Fate, 
Earthshaker's 
Echo Slam and Fissure, 
Puck's 
Dream Coil and 
Waning Rift, 
Winter Wyvern's 
Winter's Curse, Magnus's 
Reverse Polarity.
Enchantress
* Heroes that have an escape that doesn't disjoint projectiles: Mirana, Faceless Void, Magnus
Enchantress
* Range-reliant heroes: Sniper, Drow Ranger
Elder Titan
* Elder Titan's Natural Order completely nullifies Dragon Knight's high armor.
Enchantress
* Meepo can quickly kill Enchantress with a 
Poof combo, rendering Untouchable useless.
Enchantress
* Enchantress's Untouchable slows down Meepos attacks and Impetus can deal heavy pure damage to a single Meepo, however once Meepo has closed the gap she is an easy target for Poof.
Elder Titan
* Meepo lacks the disengages to escape a well-timed Echo Stomp, in particular if Elder Titan is his current target.
* Clones are counted as heroes, increasing massively the power of Astral Spirit's buffs, including Aghanim's Scepter's spell immunity buff.
* Meepo relies heavily on high agility and his mediocre strength gain makes him a very prized target for Natural Order.
* Meepo and his clones like to group up to hunt and kill in teamfights or ganks and can be easily disabled together with Echo Stomp.
Additional:
* Echo Stomp can completely disable multiple Meepos for 5 seconds.
* Astral Spirit will affect Meepo clones, as they don’t count as illusions. Elder Titan can receive a massive amount of damage, armor and movement speed from each Meepo.
* With Natural Order, Elder Titan’s mere existence causes Meepo to be disadvantaged, due to the aura that completely negates his base armor and magic resistance. Combining Astral Spirit with Natural Order allows Elder Titan to easily kill any Meepo within a second, depending on how much damage he gains from Astral Spirit. This is highly detrimental for Meepo as he is prone to buying items that grant agility like 
Disperser and Eye of Skadi.
* Earth Splitter deals over 30%/40%/50% of each Meepo’s max hp, and is even stronger if the Meepos are near Elder Titan due to Natural Order.
Enchantress
* Heroes with haste can negate Enchant's slow: Weaver, Dark Seer, Lycan, Centaur Warrunner.
Enchantress
* Lycan relies heavily on right clicks making Untouchable very effective against him.
* If he tries to run away Impetus will do huge amounts of damage.
Additional:
* She can Enchant one of the wolves to her side.
* Lycan will struggle greatly to harm Enchantress through her Untouchable which can seriously slow down Lycan's attack speed even if Lycan is spell immune.
Enchantress
* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies
Enchantress
* Spirit Breaker won’t do much harm to Enchantress because of Untouchable and Nature's Attendants. Unless Enchantress is low on HP, Spirit Breaker won’t be able to catch her with mere spells.
Enchantress
* Heroes with break can disable Untouchable for a while: Doom and Shadow Demon (via Aghanim's Scepter), Viper, Shadow Shaman with Hex Breaks talent.
Elder Titan
* Viper is an agility hero, and his item build mostly includes agility items, so Natural Order can be devastating, removing all armor and greatly decreasing the effectiveness of 
Corrosive Skin, weakening Viper's magic resistance. Additionally, Echo Stomp and Earth Splitter deal both magical and physical damage, and can help bringing Viper down fast.
* Aghanim's Scepter may be necessary to take Viper down due to 
Nethertoxin's break.
Enchantress
* Heroes that can jump on her: Slark, Queen of Pain, Anti-Mage
Elder Titan
* Natural Order aura prevents Slark from gaining armor from the agility stolen with 
Essence Shift.
* Echo Stomp and Earth Splitter can hit Slark through his Shadow Dance ultimate.
* Slark's stats gain is relatively low compared to most agility carries making him quite squishy without his agility-based armor.
Enchantress
* Heroes with nukes that can jump her: Clockwerk, Snapfire, Spirit Breaker, Techies
Additional:
* Techies does huge amounts of magical damage, which will bypass Untouchable.
* Enchantress depends on abilities to do damage and heal, which Blast Off's silence prevents.
Elder Titan
* Slow heroes that have a hard time escaping the Echo Stomp radius: Crystal Maiden, 
Pudge, Techies.
Elder Titan
* Heroes who build a Black King Bar (or have any sources of spell immunity) to channel abilities/items can still get interrupted by Dismember: Enigma, 
Juggernaut, Phantom Assassin, Pugna, Elder Titan.
Elder Titan
* Slow heroes that have a hard time escaping the Echo Stomp radius: Crystal Maiden, Pudge, Techies.
Enchantress
* Heroes like Enchantress and Chen, or heroes that make use of 
Helm of the Dominator are weak to Crystal Maiden, as Frostbite can do wonders against Enchant, Holy Persuasion, or dominated creeps. Careful though, as an army of carefully controlled creeps (Enchantress and Chen) can hold many stuns that will cancel Freezing Field.
Additional:
* 
Frostbite does 1000 magical damage to Enchantress's creeps and roots them for 10 seconds, which hinders her ability to gank.
Elder Titan
* In general, heroes with AoE or long range disables (such as Faceless Void with 
Chronosphere, Pudge with 
Meat Hook and Elder Titan with 
Echo Stomp) hinder Crystal Maiden, preventing her from using Freezing Field to help her team in a fight.
Elder Titan
* 
Storm Hammer interrupts Echo Stomp.
Enchantress
* Against her Untouchable, Sven is barely able to hit Enchantress even with his 
Black King Bar.
Enchantress
* Mirana can instantly kill creeps with Sacred Arrow, making her decent at crippling the armies of Chen or Enchantress.
Enchantress
* Heroes that have an escape that doesn't disjoint projectiles: Mirana, Faceless Void, Magnus
Enchantress
* Enchantress's lack of area-of-effect abilities allows Broodmother to swarm her with Spiderlings.
* 
Spawn Spiderlings can kill enchanted creeps and create Spiderlings in their place.
* However, bear in mind that Untouchable makes it harder for Broodmother to actually hit Enchantress, even if Broodmother is spell immune. And Broodmother's only way to counter this is either by buying Silver Edge, buying items that deal high magical damage like 
Dagon, or by buying items that give high attack speed like 
Moon Shard.
Additional:
* Enchantress can be easily overwhelmed with Broodmother's spiderlings from Spawn Spiderlings and Enchantress can only control one of them with Enchant and she has no good waveclear (Spawn Spiderlings can also kill creeps controlled with Enchant).
* However, Untouchable's attack speed reduction can make it difficult for Broodmother to kill Enchantress even with any form of spell immunity.
Elder Titan
* Echo Stomp can impede Broodmother's ability to push towers due to its low cooldown and long sleep duration.
* Astral Spirit can provide Elder Titan large amounts of damage, armor, and movement speed from her spiderlings.
* Natural Order negates Broodmother and her spiderling's base armor and magic resistance, increasing most damage dealt to them.
Enchantress
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.
Elder Titan
* Elder Titan's Echo Stomp can turn into a 5 second stun on an ally under the effect of False Promise, as it delays all damage and makes it impossible to break the damage threshold of Echo Stomp.
Enchantress
*
Blade Fury dispels the slow from Enchant, and can burst Enchantress down during the laning stage.
Omnislash and 
Swiftslash's physical damage burst ignore untouchable.
Silver Edge is a common item for Juggernaut for dealing with Untouchable.
Blade Fury dispels the slow from 
Enchant, spell immunity and used to burst her down during the early laning stage.
Omnislash and 
Swiftslash's physical damage burst ignore 
Untouchable.
Silver Edge is an ideal item for Juggernaut to deal with 
Untouchable, making her vulnerable to melee attacks.
*

Additional:

Elder Titan
*
Blade Fury makes Juggernaut immune to Elder Titan's stun, so there is a high chance he wont get caught in your ultimate although Earth Splitter pierces spell immunity.
