* 
False Promise's strong dispel removes Dark Willow's disables.
Additional:
* Fortune's End can easily dispel 
Cursed Crown before it times out and stuns. He can also save a stunned ally with False Promise.
* Fate's Edict can easily negate 
Bedlam's over-time damage, since the spell provides no form of control. Similarly, he can also negate the magic burst from 
Shadow Realm.
* Fortune's End can dispel the fear effect from 
Terrorize, and it can remove the root from 
Bramble Maze if cast quick enough. Be mindful that Fortune's End only dispels your allies' debuffs on the primary target.

Underlord
* 
Winter's Curse and 
Splinter Blast can devastate Underlord's team when they're grouped up for Dark Rift.
Dark Willow
* 
Quill Spray's constant AoE damage will hit Dark Willow even in Shadow Realm. Its automatic damage will hurt her if she tries to get close and use Bedlam.
Underlord
* 
Static Link greatly reduces Underlord damage, while benefits Razor himself, even when in Atrophy Aura's range.

Underlord
* In general, heroes with spell immunity abilities won't be caught inside by Pit of Malice: 
Juggernaut, 
Lifestealer.
Dark Willow
* 
Blade Fury dispels most of Dark Willow's abilities, allowing Juggernaut to pass through Bramble Maze and cancel out Cursed Crown before the stun occurs.
* However, Dark Willow can tank 
Omnislash with Shadow Realm. As she is a valid target, but invulnerable to right clicks.
Additional:
* None of Dark Willow's spells pierce Spell Immunity, making Blade Fury a good counter against her. Additionally, it dispels Cursed Crown and Bramble Maze.
* Dark Willow is generally fragile, which results in Omnislash being devastating against her.
* However, if Shadow Realm is activated during Omnislash, then the attack damage is negated (though Omnislash can still jump to other enemies).

Treant Protector and 
Keeper of the Light.

Dark Willow
* 
Counterspell negates Dark Willow's high magic burst damage. Its active blocks Cursed Crown.
* 
Blink allows Anti-Mage to dodge Terrorize during its long cast animation, as well as avoiding the obstacles from Bramble Maze. On the other hand, if Anti-Mage gets caught inside Bramble Maze, he's unable to Blink away.

Mana Voids.
Underlord
* 
Glimpse will return Underlord or any of his teammates attempting to escape with Dark Rift if timed correctly.

Static Storm and

Lunar Blessing gives allies bonus damage and armor required to endure against Atrophy Aura early on.
* 
Eclipse can be devastating for Underlord's team when they're grouped up for Fiend's Gate, it can also be used to intercept arrivals with Fiend's Gate. And Pit of Malice does not prevent Luna to use it.
* To make things even better, 
Aghanim's Scepter upgraded Eclipse can finish off Underlord or any of his teammates escape attempts with Fiend's Gate if timed correctly.

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
* 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.
Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: 
Techies, 
Templar Assassin, Treant Protector
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.

Phantom Assassin, Sven, 
Wraith King
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,

Centaur Warrunner, 
Jakiro, 
Leshrac, 
Naga Siren, Underlord.

Underlord
* In general, heroes that provide vision will see Fiend's Gate coming: Techies, Templar Assassin, Treant Protector
Dark Willow

Spiked Carapace can be triggered by walking deliberately into Bramble Maze, leaving Dark Willow stunned and defenseless.
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.
Underlord
* Pit of Malice can be cast in the path of Spirit Breaker's Charge of Darkness to cancel it.
* Fiend's Gate provides a way to escape from a gank for Underlord and his teammates. Likewise, Fiend's Gate can be used to ambush Spirit Breaker who has little to no ways of intercepting Underlod and his teammates when they use it to move around the map.
Dark Willow
* 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.

Nether Strike after the initial stun.
Underlord
* Damage reduction from Atrophy Aura prevents Bloodseeker from killing targets and gaining his Thirst bonuses.

* 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.

Invoker, Pugna, 
Skywrath Mage, 
Tinker,

Razor, 
Rubick, Bane, Dragon Knight and Underlord.
Dark Willow
* Bramble Maze will very likely catch Marci midair, disabling Marci's chasing/fleeing ability.
* Shadow Realm prevents Marci from bursting Willow down since she relies on physical attacks and unit target spells. With Aghanim's Scepter, Willow can hit Marci while Marci can't hit Willow.
* Bedlam and 
Eul's Scepter of Divinity allows Willow to manfight if Marci initiates with Rebound.
* Terrorize and Cursed Crown combo can waste Marci's ultimate for almost half of its duration.

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, forcing Terrorblade to buy Aghanim's Scepter that will give him access to 
Terror Wave ability.

Duels.
