Spirit Breaker
* 
Nether Strike can't remove Static Link and reduces Spirit Breaker's physical damage output.
* Eye of the Storm melts Spirit Breaker's armor, and makes him much less tanky.
Additional:
* 
Plasma Field can slow Spirit Breaker and reduce damage from Greater Bash.
* 
Static Link drains damage bonus from Greater Bash, and it cannot be removed by Nether Strike.
* 
Storm Surge will proc on Spirit Breaker every time he attacks Razor or if he uses Charge of Darkness on Razor, damaging him and alerting Razor to Spirit Breaker's incoming ganks, no matter how far Spirit Breaker is from Razor.
* 
Eye of the Storm can rapidly reduce Spirit Breaker's armor, making him much less durable, especially in teamfights.
Underlord
* Static Link greatly reduces Underlord damage, while benefits Razor himself, even when in Atrophy Aura's range.
* Underlord is a slow and low mobility hero, and cannot outrun Razor's high movement speed, easily for Razor to absorb his damage with Static Link to the maximum and burst him down from the bonus damages, combine with the armor reduction from Eye of the Storm .
Spirit Breaker
* Rubick can cancel Spirit Breaker's Charge of Darkness with 
Telekinesis under the condition that Rubick is able to cast it on time. And considering Rubick commonly buys 
Eul's Scepter of Divinity that can also cancel Charge of Darkness, Spirit Breaker will have a hard time charging Rubick or his allies until Spirit Breaker buys 
Shadow Blade. Telekinesis can also be used to cancel Nether Strike and 
Aghanim's Shard upgraded Telekinesis also allows Rubick to save his allies from Spirit Breaker.
* 
Fade Bolt weakens Spirit Breaker's damage output, reducing damage of Greater Bash.
* If Rubick succeeds to steal Charge of Darkness, he will be able to reduce much of Spirit Breaker's global presence. Rubick can also steal Nether Strike to further disable Spirit Breaker once he disables him with stolen Charge of Darkness. But bear in mind, however, that a skilled Spirit Breaker can use Bulldoze to prevent all that.
Underlord
* As a frontline tank, the abilities of 
Underlord is surprisingly spell-cast heavy, and is often great for Rubick to steal.
* 
Firestorm is a great ability for farming, pushing and serves as a useful teamfight damage source, and even more so when its damage is amplified by 
Arcane Supremacy and Aghanim's Shard.
* It is worth mention that Firestorm has no visible effect on heroes other than damage, and the enemy team may easily mistaken the ability as casted by Underlord, resulting in unexpectedly soaking up more damage.
* 
Pit of Malice is a great area control ability in teamfights, capable of trapping multiple heroes in a hazard area.
* Underlord has no immediate reposition ability, and since he usually stays at the front, he can be an easy target for Rubick's Pit of Malice.
* 
Fiend's Gate, if stolen, grants Rubick's team great versatility around the map. Creating a surprise gank or appear as a group at the enemy backline during skirmish, escaping as a team from bad situations, or even taking Roshan or enemy highground unexpectedly, the possibility are endless with careful communication among Rubick's team.
Additional:
* All of Underlord's abilities are useful for Rubick to 
Spell Steal.
Spirit Breaker
* 
Nature's Grasp severely slows down Spirit Breaker, reducing effects of Charge of Darkness and Greater Bash.
* 
Living Armor can mitigate a large portion of Spirit Breaker's damage since his attacks are slow.
* Treant Protector can also counter-initiate against Spirit Breaker with 
Leech Seed, 
Overgrowth and with his root from {I|Aghanim's Shard
* 
Aghanim's Scepter gives Treant Protector access to 
Eyes In The Forest ability, which allows him to turn trees into wards that provide vision, allowing him to keep his allies warned about Spirit Breaker's attempts to gank them. Eyes In The Forest will also trigger Overgrowth if Spirit Breaker is in range of the tree affected by it.
Additional:
* Spirit Breaker's slow attacks cannot harm a hero shielded by Living Armor.
Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: 
Techies, 
Templar Assassin, 
Treant Protector
Spirit Breaker
* Heroes that punish mobile heroes: 
Bloodseeker, 
Keeper of the Light, 
Kunkka, 
Disruptor.
Underlord
* 
X Marks the Spot will return Underlord or his teammate if they escape with Fiend's Gate.
Spirit Breaker
* 
Astral Imprisonment can be used to protect allies by imprisoning either them or Spirit Breaker.
* 
Arcane Orb will heavily drain Spirit Breaker's maximum mana, rendering him almost useless and unable to cast spells. Spirit Breakeranity's Eclipse|Outworld Destroyer
* Even if Spirit Breaker survives 
Sanity's Eclipse, mana allergy applied by the Sanity's Eclipse will discourage Spirit Breaker from using his abilities as it will cause him to lose health and heal Outworld Destroyer.
Underlord
* Tanky melee heroes that can easily be kited, which allows Outworld Destroyer to deal heavy damage with Arcane Orb from a distance: 
Sven, Underlord, 
Bristleback.
Additional:
* Arcane Orb's pure damage can do great damage to Underlord.
* Sanity's Eclipse can tear down Underlord's health by a large amount, since his mana pool is very low compare to OD's high mana pool.
Spirit Breaker
* Heroes that punish mobile heroes: Bloodseeker, Keeper of the Light, Kunkka, Disruptor.
Underlord
* 
Glimpse will return Underlord or any of his teammates attempting to escape with Dark Rift if timed correctly.
* Underlord is a slow and low mobility hero, easy to set up 
Static Storm and 
Kinetic Field, preventing him from using his abilities as well as preventing him using Fiend's Gate to escape.
Spirit Breaker
* Clockwerk can use Power Cogs to repel Spirit Breaker when he charges in with 
Charge of Darkness.
* Spirit Breaker's slow 0.6 second attack animation attacks do little damage against Clockwerk. It can also constantly be interrupted by Battery Assault.
* Nether Strike's 1.2 second charge time gives Clockwerk plenty of time to activate 
Blade Mail and for Battery Assault to cancel it.
Additional:
* 
Battery Assault will continuously prevent Spirit Breaker from using Nether Strike, Charge of Darkness and even right clicking because of his slow base attack speed.
Underlord
* Heroes with long cast animations can be continuously interrupted by Battery Assault: 
Centaur Warrunner, 
Jakiro, 
Leshrac, 
Naga Siren, Underlord.
Spirit Breaker
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; 
Spirit Breaker, 
Legion Commander, 
Axe, 
Puck, and 
Slardar.
Additional:
* 
Malefice prevents Spirit Breaker from using his spells for the duration.
* Eidolons from 
Demonic Summoning have high magic resistance, receiving little damage from Charge of Darkness and Greater Bash.
* 
Midnight Pulse can deal big damage to Spirit Breaker, as it deals damage based on enemy hero's max health.
* 
Black Hole makes it very dangerous for Spirit Breaker to reach Enigma with Charge of Darkness unless if he has Nether Strike available to use.
Underlord
* Enigma's Midnight Pulse damage can make Underlord suffer heavy damage due to his high health.
* Enigma can catch Underlord and his team off guard with Midnight Pulse and Black Hole when they teleport using Fiend's Gate. And 
Atrophy Aura offers no defense against them.
* However, Enigma needs to approach Underlord carefully as Underlord can interrupt channeling of the Black Hole with Pit of Malice and can also use Firestorm to scout Enigma's location which can also put Enigma's 
Blink Dagger on cooldown if Enigma has no 
Black King Bar available to use.
Underlord
* 
Reaper's Scythe and 
Heartstopper Aura deal percentage-based damage, ignoring Underlord's high health.
* 
Ghost Shroud protects Necrophos from Underlord's damage from Atrophy Aura, and also amplifies all the healing Necrophos receives.
Underlord
* 
Winter's Curse and 
Splinter Blast can devastate Underlord's team when they're grouped up for Dark Rift.
Spirit Breaker
* Fissure interrupts Spirit Breaker during Charge of Darkness.
Spirit Breaker
* Due to Spirit Breaker's low attack speed, 
Supernova is problematic for Spirit Breaker to take down, and even more so with 
Fire Spirits debuff applied.
Spirit Breaker
* 
Cold Snap allows Invoker to interrupt Charge of Darkness and Nether Strike.
* 
Tornado's long range can be used to cancel Charge of Darkness.
* 
Deafening Blast prevents Spirit Breaker from right clicking and thus proccing his Greater Bash.
Additional:
* Ice Wall can slow down Charge of Darkness in its tracks at max level, allowing counterplays such as Cold Snap to end the charge, bursting down with Tornado, Meteor, and right clicks, or even teleporting back to spawn to drag Spirit Breaker into the fountain.
* Cold Snap (if timed right) and Invoker's other disables like Tornado can interrupt Charge of Darkness, especially since Charge is telegraphed by the symbol appearing over head.
Underlord
* 
Fury Swipes damage is not reduced by Atrophy Aura, essentially bypassing Underlord's only natural defense.
* 
Enrage can quickly dispel the root of Pit of Malice.
Spirit Breaker
* Bramble Maze stops Charge of Darkness in its tracks. Its very long duration means it can be used as an obstacle to block off an incoming Spirit Break during teamfights.
* Shadow Realm and Bedlam can be activated when Dark Willow sees Charge of Darkness coming, preventing Spirit Breaker from using Nether Strike after the initial stun.
Underlord
* Firestorm will do little percentage damage to a small HP hero like Monkey King.
* All aspects of Jingu Mastery benefits ignore Atrophy Aura's base damage reduction.
* Monkey King can get on top of Underlord easily at any stage of the game.
Spirit Breaker
* If Medusa activates 
Stone Gaze before Spirit Breaker reaches her with Charge of Darkness, the charge will inevitably fail.
* Medusa has three ways to counter Spirit Breaker's Charge of Darkness: Stone Gaze can disable Spirit Breaker's Charge of Darkness if he faces Medusa directly. Aghanim's Scepter upgraded 
Mystic Snake can disable Spirit Breaker and cancel his Charge of Darkness if it hits him. And 
Cold Blooded provided by Aghanim's Shard that can cast a single-targeted Mystic Snake at Spirit Breaker if he uses Charge of Darkness on her.
* 
Mana Shield and overall tankiness allows Medusa to easily survive Spirit Breaker's initiation. And to make things worse, Spirit Breaker is not a common 
Diffusal Blade nor 
Disperser wielder to counter this problem at all.
* Overall, any attempt for Spirit Breaker to gank and kill Medusa will hurt him more than the other way around.
Spirit Breaker
* 
Searing Chains can stop Charge of Darkness if timed correctly.
* 
Activate Fire Remnant can be used to escape an approaching Spirit Breaker, or lead Spirit Breaker into a bad situation.
* 
Fire Remnant and 
Sleight of Fist allows Ember Spirit to dodge Charge of Darkness if timed correctly.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: 
Chaos Knight, 
Phantom Lancer, 
Terrorblade, Naga Siren, 
Broodmother, 
Warlock, 
Visage, 
Nature's Prophet, 
Shadow Shaman, 
Lycan.
Spirit Breaker

Spectre, 
Nyx Assassin, 
Clockwerk, Spirit Breaker,

Juggernaut, 
Lifestealer.
Spirit Breaker

Ogre Magi, 
Earthshaker, Lion, 
Rubick, 
Luna.
Spirit Breaker

Razor, Axe, Bristleback, Leshrac, 
Death Prophet.
Spirit Breaker
* Heroes who can continue dealing damage even while being stunned: Luna, Razor, Axe, Bristleback, Leshrac, Death Prophet.
Underlord
* Durable heroes relied a lot on their main passive effects and items' effects such as Bristleback, Underlord, Spectre and 
Dragon Knight can be disabled easily with 
Sharpshooter's break, reducing their potential in teamfights.
Spirit Breaker
* Heroes that punish mobile heroes: Bloodseeker, Keeper of the Light, Kunkka, Disruptor.
Spirit Breaker
* Heroes who can continue dealing damage even while being stunned: Luna, Razor, Axe, Bristleback, Leshrac, Death Prophet.
Spirit Breaker

Shadow Demon, 
Outworld Destroyer, Omniknight, 
Dawnbreaker.
Spirit Breaker
* Durable heroes: Axe, Dawnbreaker, Bristleback, 
Tidehunter, 
Wraith King, 
Primal Beast, Underlord.
Additional:
* Solar Guardian can save an ally getting targeted and focused by Spirit Breaker.
Spirit Breaker
* Heroes with mobility spells like 
Queen of Pain, 
Anti-Mage, 
Phantom Assassin, 
Riki, Puck, and Spirit Breaker that are cancelled by Frostbite can suffer greatly from the presence of Crystal Maiden. It is absolutely critical, however, to have followup from teammates, as all of the above heroes can make quick work of the squishy Crystal Maiden after they are released from her grip.
Spirit Breaker
* Durable heroes: Axe, Dawnbreaker, Bristleback, Tidehunter, Wraith King, Primal Beast, Underlord.
Spirit Breaker
* 
Mana Drain has an fair long range and low cooldown. It can easily deplete most heroes of their entire mana pools, especially those with smaller mana pools such as 
Tiny or Spirit Breaker.
Spirit Breaker
* Heroes that usually build 
Linken's Sphere as a core or situational item: 
Weaver, 
Medusa, 
Morphling, Queen of Pain, 
Storm Spirit, Luna.
Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: Techies, Templar Assassin, Treant Protector
Spirit Breaker
* Can easily interrupt and disable Spirit Breaker with hex if being charged.
Spirit Breaker
* Heroes that are squishy by nature are an easy target for Spirit Breaker: 
Sniper, 
Drow Ranger, Shadow Shaman
Spirit Breaker
* Due to Spirit Breaker's low attack speed, 
Tombstone is problematic for Spirit Breaker as the zombies summoned from Tombstone apply a stacking movement speed slow, which can significantly reduce Greater Bash's damage.
* 
Soul Rip and 
Decay allows Undying and his allies to survive and recover from any incoming ganks by Spirit Breaker.
Underlord
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, Dragon Knight, 
Meepo, 
Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, Legion Commander.
Spirit Breaker
* In the early game, Omniknight can look like an easy target for Spirit Breaker, but with 
Purification and 
Hammer of Purity, what could be an opportunity could quickly turn into disaster.
* 
Repel can be used to counter Charge of Darkness by minimizing the damage and lowering the stun duration with status resistance.
* Spirit Breaker's Greater Bash from all sources (Charge of Darkness or normal attacks) will deal no damage at all if Omniknight and his allies are protected with presence.
* Due to this, Spirit Breaker's damage will always be lower when targeting Omniknight.
Underlord
* In general, heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by Dark Rift or Fiend's Gate (Requires Aghanim's Scepter): Terrorblade, Dragon Knight, Omniknight.
Spirit Breaker
* 
Morph allows Morphling to copy abilities of Spirit Breaker and combine them with 
Waveform to turn things around. Aghanim's Scepter upgraded Morph also allows Morphling to create a strong illusion of Spirit Breaker that can cast all of his basic abilities. This allows Morphling to give Spirit Breaker a taste of his own medicine.
* Spirit Breaker's low attack speed and lack of burst damage makes it unlikely for him to win against Morphling when he has 
Attribute Shift (Strength Gain) toggled on.
Underlord
* Underlord's Atrophy Aura reduces Morphling's high base damage gained through agility shift.
Spirit Breaker
* Spirit Breaker's slow attack speed and moderate damage do very little to harm Dragon Knight, even if ganked with Charge of Darkness.
Underlord
* In general, heroes with long cooldowns on their abilities or ultimate will struggle against the relentless pressure provided by Dark Rift or Fiend's Gate (Requires Aghanim's Scepter): Terrorblade, Dragon Knight, Omniknight.
Spirit Breaker
* 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.
Spirit Breaker
* Heroes with nukes that can jump her: Clockwerk, 
Snapfire, Spirit Breaker, Techies
Spirit Breaker
* Charge of Darkness can be used to chase down Pangolier if he escapes with Swashbuckle or Rolling Thunder.
* Nether Strike ignores Rolling Thunder's spell immunity, and will still hit Pangolier if he rolls or dashes away.
Underlord
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: Treant Protector, Meepo, 
Crystal Maiden, 
Dark Willow, Underlord, Naga Siren
Spirit Breaker
* Heroes that rely on escapes to stay alive can be caught and locked down for a long time: Queen of Pain, Phantom Assassin
Underlord
* Firestorm can deal serious damage to Phantom Assassin during laning.
* Pit of Malice prevents Phantom Assassin from either escaping or engaging with 
Phantom Strike.
* Phantom Assassin's damage output is entirely physical, therefore Atrophy Aura is very hazardous for her in most of the stages, particularly since it also affects 
Coup De Grace, hindering Phantom Assassin's main source of damage.
* Without proper items and any area-of-effect ability/item, Phantom Assassin cannot stop Underlord and his team to escape with Fiend's Gate, and she has nothing to intercept Underlord and his team when they use Fiend's Gate to teleport on any area of the map outside of 
Fan of Knives from Aghanim's Shard.
Additional:
* Pit of Malice prevents Phantom Assassin from either escaping or engaging with Phantom Strike.
* Phantom Assassin's damage output is entirely physical, therefore Atrophy Aura is very hazardous for her in most of the stages, particularly since it also affects Coup De Grace Coup de Grace, hindering Phantom Assassin's main source of damage.
* Without proper items and any area-of-effect ability/item, Phantom Assassin cannot stop Underlord and his team to escape with Fiend's Gate, nor she can intercept them if Underlord chooses to teleport on any area of the map.
Spirit Breaker
* Generally, heroes that can close the gap on Drow Ranger to cancel her Marksmanship such as Phantom Assassin, Spirit Breaker, and 
Tusk are effective at limiting her power and bursting her down.
Underlord
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies on agility to be effective.
Spirit Breaker
* Spirit Breaker's Charge of Darkness semi-reveals Bounty Hunter, taking away his element of surprise for the duration of the charge. Also, as Charge of Darkness shows Bounty Hunter's position, Spirit Breaker's allies can proceed to gank Bounty Hunter while he is roaming alone.
Underlord
* In general, attacks of the melee heroes who are entirely reliant on dealing physical damage and/or have very little to no area-of-effect abilities will make Underlord tickle and will have no effect against him, and will be unable to ambush Underlord and his team if Underlord chooses to use Fiend's GAte to get to a designated point of the map: Phantom Assassin, Terrorblade, 
Troll Warlord, Drow Ranger, Phantom Lancer, Chaos Knight, Sven, Wraith King, Bounty Hunter, Alchemist, Templar Assassin, Nyx Assassin, 
Bane.
Spirit Breaker
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer

Blink Strike. or 
Tricks of the Trade.
* Atrophy Aura reduces Riki's damage.
* Firestorm can be used to harrass Riki in lane.

* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, 
Clinkz, Sniper, 
Slark, Phantom Assassin, 
Void Spirit, Storm Spirit, 
Ember Spirit, 
Earth Spirit, Spirit Breaker.
Underlord
* Firestorm will easily clear Chen's creeps.
* Pit of Malice will trap Chen and render him helpless.
* Atrophy Aura gives bonus damage to Underlord for each killed creep and weakens Chen's damage output.
* Fiend's Gate can counter Chen's pushing attempts, and he has nothing to intercept it.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan.
Spirit Breaker
* Spirit Breaker can chase Nature's Prophet from anywhere on the map with Charge of Darkness, making it hard for Nature's Prophet to split-push.
* Charge of Darkness and Nether Strike gives vision of Nature's Prophet when he tries to Sprout himself and teleport away.
Additional:
* Charge of Darkness allows Spirit Breaker to catch Nature's Prophet out when he tries to split push.
* Nature's Prophet can't hide in his 
Sprout against Spirit Breaker, as his Charge of Darkness provides vision on its target.
* Spirit Breaker can easily cancel Nature's Prophet's 
Teleportation.
Underlord
* Firestorm makes quick work of Treants and Atrophy Aura gives him temporary damage for every Treant killed.
* Pit of Malice can stop Teleportation channeling.
* Atrophy Aura greatly reduces Nature's Prophet's damage and he has no other good way to deal damage.
* Fiend's Gate can counter split-pushing, which is something that Nature's Prophet relies on a lot. Fiend's Gate can also be used to either escape from Nature's Prophet or to prepare an ambush on Nature's Prophet, and outside from Nature's Wrath, Nature's Prophet has no other ways to intercept arrivals with Fiend's Gate.
Spirit Breaker
* Heroes with summons and illusions as Spirit Breaker has no strong AoE capabilities to deal with them: Chaos Knight, Phantom Lancer, Terrorblade, Naga Siren, Broodmother, Warlock, Visage, Nature's Prophet, Shadow Shaman, Lycan.
Spirit Breaker
* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters: Bane, Lifestealer, Spectre, Chaos Knight, Spirit Breaker, Sniper. Terrorblade's only solution to counter this problem is to get 
Manta Style as quickly as possible.
Underlord
* Atrophy Aura reduces Terrorblade's damage significantly, even during Metamorphosis.
* Firestorm deals significant damage to Terrorblade and his illusions from a safe distance.
* Pit of Malice can keep Terrorblade and his illusions under control.
* Fiend's Gate can either bail out Underlord's team away from a bad engagement against a Terrorblade under Metamorphosis or caught Terrorblade off guard if he is not careful, and besides 
Reflection, Terrorblade has no other abilities to intercept Underlord nor his team when they use it to start a teamfight.
* Likewise, Fiend's Gate can be used to quickly move Underlord's team to the frontlines, to strike Terrorblade and his allies during Metamorphosis's 150 seconds of cooldown.
Additional:
* Firestorm deals significant damage to Terrorblade and his illusions from a safe distance.
* Pit of Malice can keep Terrorblade and his illusions under control.

Likewise, Fiend's Gate can be used to quickly move Underlord's team to the frontlines, to strike Terrorblade and his allies during Metamorphosis's 150 seconds of cooldown, forcing Terrorblade to buy Aghanim's Scepter that will give him access to 
Terror Wave ability.
Underlord
* 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.
Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: Techies, Templar Assassin, Treant Protector
Spirit Breaker
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a 
Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, Warlock.
Underlord
* Firestorm will destroy 
Refraction charges very quickly.
* Firestorm will hit Templar Assassin while under the effects of 
Meld Meld.
* Templar Assassin has a hard time maneuvering around Pit of Malice.
Underlord
* Atrophy Aura's percentage-based damage reduction greatly diminishes Legion Commander's overall damage output, even if she has won many Duels
* Legion Commander cannot get out the way of Firestorm because she is stationary.
Additional:
* Atrophy Aura makes it hard for Legion Commander to win 
Duels.
* Fiend's Gate can be used to save Underlord and his allies from a Duel or to intercept Legion Commander, because outside from 
Overwhelming Odds, Legion Commander has no other area-of-effect abilities.
Spirit Breaker
* Magic Missile has a considerably long cast time, making it difficult to stop Charge of Darkness with it.
* Other than Magic Missile, Vengeful Spirit has no way of canceling Nether Strike.
Underlord
* Atrophy Aura decreases Troll Warlord's damage.
* Pit of Malice helps lock down Troll Warlord.
* Battle Trance disallows Troll from running out of both Firestorm and Pit of Malice.
Spirit Breaker
* Tinker relies on his high mobility from 
Boots of Travel and Blink Dagger to survive. Those items don't help him if Spirit Breaker manages to cast Charge of Darkness on him.
* Spirit Breaker can easily cancel 
Rearm and Boots of Travel.
Spirit Breaker
* Possibly Clinkz's worst enemy. He has many tools to utterly destroy Clinkz.
* Charge of Darkness can be used on Clinkz if Spirit Breaker's team spots him anywhere. This charge will track his location through Skeleton Walk's invisibility and movement speed bonuses.
* When Spirit Breaker charges onto Clinkz, he can easily use Dust of Appearance to guarantee a reveal on him while stunned.
* All three of Spirit Breaker's spells help him and his team quickly close the gap to Clinkz even at the edge of his attack range or when running away with Skeleton Walk.
* Spirit Breaker's high strength and above average armor makes him able to endure Clinkz's onslaught, meanwhile Clinkz will be heavily threatened if Spirit Breaker procs a 
Greater Bash.
Additional:
* Once caught with dust, Clinkz could be locked down for a long time by Spirit Breaker and has nowhere to escape.
* Charge of Darkness provides shared vision over its target, showing Clinkz even when he is in 
Skeleton Walk.
Spirit Breaker
* Anti-Mage usually relies on 
Blink to escape, but with vision from Charge of Darkness it is easier to catch him.
* Spirit Breaker could single-handedly lock Anti-Mage down for 4 seconds (or even more with lucky bashes), allowing his teammates to follow up.
* As Anti-Mage is an elusive hero who likes to farm alone, Spirit Breaker could choose to charge whenever Anti-Mage is in sight.
Underlord
* Firestorm's percentage damage can quickly demolish the Spirit Bear's high HP
* Pit of Malice will allow allies to easily kite Lone Druid due to his low mobility
Underlord
* In general, melee heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice: Sven, Tiny, Wraith King, Dragon Knight, Meepo, Doom, Bounty Hunter, Dark Seer, Undying, Alchemist, Legion Commander.
Spirit Breaker
* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, 
Huskar, Wraith King: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.
