Techies
* Aphotic Shield makes it less likely for allies to be killed by mines.
* Because they explode in very short intervals, a stack of 
Remote Mines will always trigger Borrowed Time, making them impossible to kill Abaddon unless his resistances are lowered enough or Abaddon is affected by Break.
* Abaddon can easily dispel the long-lasting root of 
Stasis Trap on himself and on an ally, while at the same also providing protection against the other mines' damage.
Additional:
* 
Borrowed Time's automatic activation will help Abaddon survive a field of Proximity Mines or a Blast Off combo. However, the damage from a single mine can kill him if his HP is low enough.
* 
Aphotic Shield's can easily break Techies' Etheral Blade combo.
Primal Beast
* Borrowed Time allows him to both exit his stuns prematurely and turn Trample into healing for himself. His Aghanim Scepter only prevents the automation of the spell, Abaddon himself can still manually activate it.
* Aphotic Shield will immediately debuff any stuns Primal Beast has put on allies but won't stop him from being stunned if casted on Abaddon.
Techies
* Shadow Demon's spammable illusions can be used to scout Techies' 
Proximity Mines. The illusion of your carries can be even used to trick Techies into detonating his precious Remote Mines.
Primal Beast
* Primal Beast really suffers against supports he cannot bully in the lane: this includes 
Dazzle, 
Shadow Demon and 
Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Techies
* Heroes with summons like 
Broodmother, 
Enigma, 
Nature's Prophet; or illusions, like 
Naga Siren, 
Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Primal Beast
* 
Malefice will prevent Primal Beast from doing anything for a long duration even in the early game when at his strongest.
* 
Midnight Pulse will scale with his max health so will do a ton of damage combined with any generic stun or Enigma's own abilities.
* Primal Beast relies completely on mobility to do damage, 
Black Hole makes sure he cannot use any abilities or threaten heroes he is typically good against.
Techies
* 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.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force 
Black King Bar in fights unideally, such as 
Shadow Shaman, Lion, 
Nyx Assassin.
Techies
* Familiars can fly over the mines, rendering them safe from damage of Techies's mines. Visage can also use Familiars to check for mines on the map.
* Techies's low attack speed and damage will give them a hard time in destroying Visage's Familiars, and that can become even worse if they are affected by 
Grave Chill.
* 
Gravekeeper's Cloak allows Visage to survive Damage from Techies's mines.
Techies
* Wraith King is not afraid to walk into mines, whenever he goes with his Reincarnation ready.
Techies
* Thanks to 
Counterspell's magic resistance, Anti-Mage has a good chance of surviving a Blast Off combo.
* Anti-Mage is a natural 
Manta Style carrier, meaning he can dispel the silence from Blast Off and blink away when Techies initiates on him.
Techies
* Plague Wards may reveal a hiding Techies. If there's a sentry nearby, they may also reveal a stack of mines hidden in a juking spot.
Techies
* 
Dark Ascension also allows Night Stalker to fly over Proximity Mines without triggering them.
* 
Crippling Fear is effective in stopping Techies from using Blast Off and 
Void is effective in stopping them from running to the safety of their mines.
Primal Beast
* The ensnare from melee 
Berserker's Rage can prevent Primal Beast from dealing further Trample damage and can allow Troll Warlord to relentlessly build 
Fervor on him.
* 
Whirling Axes (Ranged) can slow down Primal Beast while trampling and allow Troll Warlord to better control him from range.
* 
Whirling Axes (Melee) can blind Primal Beast if he attempts to auto-attack Troll Warlord after a fully charged Uproar.
* 
Battle Trance will make Primal Beast a sitting duck should he be rooted and attacked to death.
Techies
* He can send wolves to defuse Proximity Mines, and he can catch up Techies and kill him before they can deny themselves. Even if the suicide is successful, Lycan can still survive because of his tankiness.
Primal Beast
* 
Soulbind prevents Primal Beast from being able to use Onslaught or his abilities to great effect for a lengthy amount of time.
* 
Phantom's Embrace is very difficult for Primal Beast to remove due to his slow attack speed and Trample preventing him from attacking.
Primal Beast
* 
Time Walk makes it impossible for Primal Beast to stay on top of Faceless Void with his abilities and allows him to heal burst damage dealt to him.
* Once Faceless Void has an 
Aghanim's Shard, Onslaught can be easily escaped. He could also choose to get a lower cooldown on Time Walk, making it even harder for Primal Beast to catch him in fights or stop his initiations.
* 
Time Dilation will make Primal Beast useless for an extended time after casting his abilities if he does not have a dispel.
* 
Chronosphere has many uses such as stopping Primal Beast from casting abilities on him or allies or even on a teammate, since Primal Beast has no way to assist allies trapped within the sphere.
Techies
* 
Corrosive Skin will protect Viper from Techies' magical damage.
* Even though Reactive Tazer will disarm Viper if he attacks Techies with 
Poison Attack, he does lots of damage with his other abilities that can still kill Techies.
Primal Beast
* Invoker's numerous area-of-effect abilities can interrupt Primal Beast, especially while he is in the middle of a team fight, where Primal Beast thrives. (
Tornado, 
Cold Snap, and 
Ice Wall all help to disable Primal Beast and control him from a distance.
* 
E.M.P. disintegrates Primal Beast's low mana pool.
* However, Invoker is quite a slow-paced hero and not particularly known for being survivable against a rampaging Primal Beast with Black King Bar.
Primal Beast
* Primal Beast's abilities require movement to deal damage, making 
Rupture potentially deadly and debilitating. Furthermore, its initial damage based on the target's current health is devastating to a full-health Primal Beast with his high strength gain and thus high HP.
* Due to his reliance on spells, Primal Beast is vulnerable to 
Blood Rite's powerful silence without items to counter it.
Techies
* 
Exorcism's ghosts will automatically clear all Proximity Mines revealed when Death Prophet walks near them, provided that the ghosts do not have a specific target at that time.
* Death Prophet is a natural 
Eul's Scepter of Divinity carrier, meaning she can easily escape a Blast Off initiation.
Techies
* 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.
Primal Beast
* 
Glimpse can prevent Primal Beast from initiating for most of the game with Onslaught.
* While 
Static Storm is not much of a threat in terms of damage, it does prevent Primal Beast from casting any spells for a long period of time if also trapped in 
Kinetic Field.
* Overall, Disruptor forces Primal Beast to buy a Black King Bar much earlier than he might like but becomes a major threat to Disruptor once he does.
Primal Beast
* 
Power Cogs keeps Primal Beast pinned down, preventing him from doing damage with Trample. Primal Beast's slow attack speed makes it hard for him to break the cogs and get away. In addition, Power Cogs' knockback is forced movement and thus will intercept Primal Beast's Onslaught if placed well.
* 
Battery Assault on a lone Primal Beast in the early game effectively keeps him from winding up Onslaught or basic attacking.
* 
Rocket Flare and 
Jetpack (from purchasing Aghanim's Shard) give Clockwerk many options to scout for Primal Beast, whose kit benefits greatly from ambushing.
Techies
* As long as Batrider is under the effect of Firefly, he can safely fly over Proximity Mines (He does not receive vision over the mines).
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as 
Troll Warlord, 
Lone Druid and 
Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
Techies
* Slow heroes that have a hard time escaping the Echo Stomp radius: 
Crystal Maiden, 
Pudge, 
Techies.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Techies
* Illusions can be sent out to destroy Techies mines.
Primal Beast
* Primal Beast is mostly played in the offlane role, so picking a carry who can escape from him is essential. Heroes such as Troll Warlord, Lone Druid and Outworld Destroyer, or generally any carry with a stun, slow or ability to fight back will stop him from having the good start he needs.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: 
Lich, 
Ogre Magi, 
Winter Wyvern.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, Ogre Magi, Winter Wyvern.
Primal Beast
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: Lich, Ogre Magi, Winter Wyvern.
Primal Beast
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Primal Beast
* Any ganking heavy support can be a big problem for Primal Beast, such as: 
Earth Spirit, 
Grimstroke before he has a Black King Bar.
Techies
* Heroes with low health will die easily during Duels, and can be farmed for damage in the early game: Crystal Maiden, Lich, Techies, 
Rubick
Primal Beast
* Primal Beast really suffers against supports he cannot bully in the lane: this includes Dazzle, Shadow Demon and Dark Willow since they can use their respective abilities to stop Primal Beast from dealing burst damage, or make it hard for him to stay in range.
Techies
* 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.
Techies
* Rage protects Lifestealer from all of Techies' abilities. 
Reactive Tazer's disarm will also not work on Lifestealer under Rage.
* Rage can also be used to trigger Techies' Proximity Mines safely.
Additional:
* Lifestealer's 
Rage lets him clear Proximity Mines without taking damage, and allows him to hit heroes whom Techies has used Reactive Tazer on.
Primal Beast
* Special mention to 
Lifestealer who can use Rage to prevent Trample damage, but Primal Beast's ultimate can still be casted during the spell.
Primal Beast
* 
Shukuchi allows Weaver to have faster movement speed and can outrun Primal Beast in most instances, such as while he is trampling.
* Trample disarms Primal Beast, so casting 
The Swarm can make him vulnerable to ranged attacks. Primal Beast also has an innately slow attack speed and will take a long time destroying the bugs.
* 
Time Lapse allows Weaver to negate and heal burst damage, which Primal Beast is reliant on.
Techies
* Techies is very good against roaming supports and gankers such as 
Bounty Hunter, 
Riki, 
Weaver, 
Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
Techies
* 
Refraction can be very useful in safely neutralizing Proximity Mine fields, or absorbing Techies' Blast Off combo.
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like 
Keeper of the Light, 
Luna, 
Templar Assassin...
Primal Beast
* 
Pit of Malice is very good at preventing Primal Beast from entering the fight and stopping Trample damage at all stages of the game.
Techies
* In general, heroes that provide vision will see Fiend's Gate coming: Techies, Templar Assassin, 
Treant Protector
Techies
* Morphling usually has low max health due to shifting strength into agility, which combined with Blast Off's silence will prevent him from using 
Waveform and 
Adaptive Strike (Strength), leaving him defenseless and making him an easy target to burst down.
Primal Beast
* Morphling relies on 
Attribute Shift (Agility Gain) to take last-hits. Primal Beast's burst damage ability can constantly threaten Morphling, especially due to his short attack range. If forced to escape with Waveform, Primal Beast can catch up with Onslaught.
Techies
* Techies has great area of effect damage to deal with 
Phantasm illusions.
* Blast Off silences Chaos Knight, stopping him from using his disables and allowing his teammates to walk away from his heavy damage.
* Reactive Tazer will disarm all of Chaos Knight's illusions even if he has activated his Black King Bar.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as 
Chaos Knight, Naga Siren, Terrorblade.
Techies
* Heroes with summons like Broodmother, Enigma, Nature's Prophet; or illusions, like Naga Siren, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Techies
* Techies deals lots of magical damage with 
Sticky Bomb, Blast Off! and Proximity Mines that bypasses Terrorblade's high armor and can punish his low max life.
* Sticky Bomb is easy to land on a large clump of Terrorblade illusions and will damage and slow Terrorblade and all of his illusions if he can't quickly move the right one away.
* Reactive Tazer upgraded with 
Aghanim's Scepter can be used to protect an ally getting attacked by Terrorblade. Further, it disarms all of his illusions even while he has activated Black King Bar, greatly decreasing his damage.
* Blast Off! stuns Terrorblade, preventing him from casting 
Sunder.
Primal Beast
* Terrorblade has no stun and is vulnerable to Primal Beast's spell comboes due to his low health points in the laning stage and mid game.
* 
Reflection can be dispelled using Primal Beast's level 15 left talent.
* Sunder is the only real threat Terrorblade has against Primal Beast but he may die before he can even use it.
Primal Beast
* Phantom Assassin is known to be weak against bursts of magical damage, something Primal Beast excels at from the beginning of the game. He can use this to his advantage by constantly hunting Phantom Assassin down, especially if she is left alone to farm.
* Primal Beast is a good carrier of 
Ethereal Blade, 
Vanguard and 
Shiva's Guard all of which are very good against 
Coup de Grace and 
Phantom Strike.
* Even though Primal Beast does a lot of physical damage early on, later once 
Blur becomes more potent, she may find herself being overwhelmed by Trample and Onslaught instead.
* Primal Beast's ultimate goes through spell immunity and his level 25 talent makes it even more devistating against Phantom Assassin.
Primal Beast
* Onslaught prevents all of Razor's abilities from being effective against him, especially in the laning stage.
Techies
* If Storm Spirit isn't careful, he could fall into a trap set by Techies and another hero acting as bait.
* Stasis Trap roots Storm Spirit for 2/3/4/5 seconds and Blast Off! silences for 4/5/6/7 seconds, which effectively prevents Storm Spirit from using 
Ball Lightning to escape for a lengthy duration.
Techies
* After using Snowball, Tusk can't control where he's going, allowing Techies to make him roll onto mines.
Techies
* Proximity Mines can be placed near trees to detect Monkey King.
* Follow up with Blast Off! to destroy the tree, causing Monkey King to take high damage, fall from the tree, and become stunned.
Additional:
* Techies can turn his tree jumping ability against him, by placing Proximity Mines that will detect him near trees, and then destroying the trees around him with Blast Off, stunning him and dealing high damage, on top of him being silenced when the stun expires.
* Monkey King's mobility is also severely limited around Techies' mines as he will almost always trigger them due to the cooldown time between tree jumps. Monkey King will be forced to take mine damage or escape with 
Primal Spring.
Primal Beast
* Primal Beast is one of Sniper's greatest counters, as he has no real means of escape and is very squishy, especially in the early game. Sniper's potshots and 
Shrapnel can contribute to Primal Beast's Uproar and further make him tankier than he already is. Onslaught allows him to close the gap on Sniper at his own volition, and Trample can deal serious damage to his meager health pool.
Primal Beast
* 
Dark Pact, 
Shadow Dance and 
Depth Shroud will do nothing against Onslaught and Trample, as they are both ground area-of-effect spells.
* Primal Beast has a gigantic hitbox, which could be difficult for Slark to escape with 
Pounce should Primal Beast choose to block him. Pounce also does not completely prevent Primal Beast from trampling offensively, as he still has some room to move.
* Primal Beast has a huge health pool making it difficult to shed it with 
Essence Shift and may llow Primal Beast to build Uproar stacks against him very rapidly.
Techies
* Remote Mines are frequently placed in trees, and can thus kill an unwary Hoodwink should she 
Scurry away due to her low HP pool.
* Blast Off! can clear out trees, denying the tactical advantages from Scurry.
Primal Beast
* 
Pierce the Veil does not prevent Primal Beast from using any of his spells to their fullest and is one of the few heroes that can disable her during her ultimate and a common Black King Bar purchase.
* 
Gunslinger will be disabled if Primal Beast buys an Aghanim's Scepter.
Primal Beast
* Primal Beast has multiple ways to cancel 
Life Drain very quickly.
* Pugna has a very low strength gain and as a support does not have much gold to buy health items, making him vulnerable to Primal Beast's onslaught of magical damage.
* Ironically, 
Decrepify actually just increases Primal Beast's damage on the targeted ally if Trample is activated. However, it can be used to slow him down and prevent any further Trample damage.
Primal Beast
* Since Primal Beast is highly mobile with Onslaught alone, he will be difficult to catch with both 
Cold Feet and 
Ice Blast.
* Ice Blast is less effective due to Primal Beast's massive health pool and resistance to taking damage.
* While 
Chilling Touch can be used to slow Primal Beast briefly, it is not enough to beat him back, and can also contribute to his Uproar stacks.
* Primal Beast has a dispel talent at level 15 that will remove Cold Feet immediately when Uproar is used.
Primal Beast
* 
Dispersion reduces damage based on a percentage, which is very minimal against large amounts of small instances of damage such as Trample. It reduces each tick by about 14 at the maximum level, which is very small.
* 
Desolate is never a threat to Primal Beast due to his large health pool and Uproar is still out-damaging the ability.
* Onslaught can allow Primal Beast to chase Spectre fleeing with 
Spectral Dagger, as both skills phase through trees and terrain.
* Primal Beast can also dispel Spectral Dagger's slow with his left level 15 talent, making it completely useless against him.
* Primal Beast excels at early aggression, pushing weak carries out of lane and farming areas he wants to control. Overall just not a pleasant
Techies
* Techies can easily catch Chen off guard and kill him quickly with Blast Off! and Ethereal Blade combo, especially because Blast Off! can silence Chen and stun him when upgraded with Aghanim's Shard.
* However, Chen's converted creeps can trigger Proximity Mines, wasting them.
Techies
* Reactive Tazer can lock multiple Meepos in place and prevent them from Poofing.
* Proximity Mines, Sticky Bomb and Blast Off! can deal heavy magic damage to multiple Meepos.
Techies
* 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.
Primal Beast
* Hard carries who just want to farm and be left alone will not appreciate Primal Beast, heroes such as 
Medusa, Drow Ranger...
Primal Beast
* Any hero with low mobility and max healthsuch as 
Silencer, Crystal Maiden etc.
Primal Beast
* Any hero who lanes very poorly will struggle with Primal Beast's potential snowball in the very early levels, like Keeper of the Light, Luna, Templar Assassin...
Primal Beast
* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as 
Legion Commander, 
Beastmaster and 
Primal Beast are good examples of this.
Additional:
* 
Berserker's Call will be a stun for Primal Beast and not much else due to Trample making him unable to attack.
* 
Battle Hunger is neglitable because Primal Beast has a much bigger health than Axe, so he does not need to fear being slowed, or his other abilities including 
Counter Helix or even a 
Blade Mail.
* Getting Primal Beast low enough to use a successful 
Culling Blade can be very difficult due to his massive health advantage over most heroes.
* Not ability related but Primal Beast does not need to fear Axe in lane, as Trample, combined with Uproar and Onslaught will do a ton of damage even if Axe has a Vanguard.
Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like 
Witch Doctor and 
Omniknight should play very cautiously alone...
Primal Beast
* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.
Techies
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
Primal Beast
* Durable heroes: 
Axe, 
Dawnbreaker, 
Bristleback, 
Tidehunter, 
Wraith King, Primal Beast, 
Underlord.
Techies
* Techies is very good against roaming supports and gankers such as Bounty Hunter, Riki, Weaver, Earthshaker, Nyx Assassin, etc. that are constantly moving around the map.
Primal Beast

Techies

Primal Beast
* Heroes who cannot escape from Trample early might be easy first blood. Heroes like Witch Doctor and Omniknight should play very cautiously alone...
Techies
* 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.
Primal Beast
* 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.
Techies
* Heroes with summons like Broodmother, Enigma, Nature's Prophet; or illusions, like Naga Siren, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Primal Beast
* 
Sprout gets destroyed by Trample and Onslaught.
Techies
* Heroes with summons like Broodmother, Enigma, Nature's Prophet; or illusions, like Naga Siren, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Primal Beast
* While Broodmother can hide in the trees with 
Spin Web, Primal Beast's ability to trample trees down can give him an edge in catching her.
* 
Insatiable Hunger will not do much vs Primal Beast's onslaught of disables.
* While 
Silken Bola can slow Primal Beast down, it's not enough to stop Trample from doing more damage than Broodmother can do back.
* 
Spawn Spiderlings will be destroyed by Onslaught and Trample very easily.
Techies
* 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.
Primal Beast
* Heroes who have low or high armor but very high health will be difficult for drow to burst down quickly: Primal Beast, Axe, 
Centaur Warrunner.
Techies
* Juggernaut can trigger Proximity Mines while in 
Blade Fury, and can walk away from a initiation with Blast Off if Blade Fury is activated before the silence.
* Juggernaut ignores Reactive Tazer when he uses 
Omnislash, whether Techies used it to protect an ally or themselves.
Primal Beast
* Primal Beast can use Uproar to tank a portion of Omnislash, giving him an edge in surviving it. Primal Beast can also dash away after Omnislash with Onslaught, disallowing Juggernaut from any follow-ups.
* Blade Fury will never do more damage than Uproar once the stacks are activated.
* Primal Beast is very commonly buying items that are good against Juggernaut, such as Ethereal Blade and 
Heart of Tarrasque.
* Primal Beast has one of the few ultimates that can prevent Juggernaut from spinning away with a teleport.
Primal Beast
* Like above, supports with reliable stuns can be a massive problem and force Black King Bar in fights unideally, such as Shadow Shaman, Lion, Nyx Assassin.
Techies
* Some abilities deals damage from an independent source and not from the hero itself, so Nyx cannot counter them with Spiked Carapace: illusions or summoning units, 
Homing Missile, 
Nimbus, 
Mass Serpent Ward, 
Death Ward and especially Techies's mines.
Techies
* Heroes with summons like Broodmother, Enigma, Nature's Prophet; or illusions, like Naga Siren, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Primal Beast
* Illusion heroes will struggle against Primal Beast's area damage capability, such as Chaos Knight, Naga Siren, Terrorblade.
Techies
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, 
Enchantress, 
Gyrocopter, Lion, Riki, Techies, Terrorblade, 
Necrophos, 
Invoker.
Primal Beast
* Heroes with unorthodox escapes will struggle against Primal Beast, such as Nature's Prophet, 
Tinker, and Templar Assassin.
Techies
* Oracle can negate all of Techies' skills with Fate's Edict, as they are all magic damage. Fate's Edict can also be used to search and trigger
Proximity Mines when crossing mined territory.
Reactive Tazer off Techies, as well as the silence from 
Blast Off!, with Fortune's End.
Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage.
Fortune's End dispels Reactive Tazer buff from Techies allowing him to be attacked. However, Reactive Tazer will instantly perform the area of effect disarm that is normally applied at the end of the duration.
* Oracle can dispel
* Oracle can further delay Techies' burst damage capability with False Promise.
Additional:
*
* Oracle's
* Fortune's End will also dispel Blast Off silence, Techies' Etheral Blade, Proximity Mines' magic resistance reduction, and Sticky Bomb's slow. However beware that it will only dispel Sticky Bomb's first or second instance of slow and not the damage, which will trigger as normal.
Primal Beast
* Oracle can negate and shut down Primal Beast simply with Fate's Edict, especially in the early game, as a majority of his damage-dealing spells are magic.
Onslaught charge with a well-timed Fortune's End.
Fate's Edict completely negates all of Primal Beast's major damage-dealing spells in the early game and can render Primal Beast useless when cast on a target he is focusing, or in Oracle's defense against Primal Beast himself. 
Fortune's End keeps Primal Beast in place, especially while trampling or in the middle of an Onslaught charge.
False Promise can interrupt Primal Beast's abilities, as well as further delay Primal Beast from dealing lethal burst damage. In combination with 
Fortune's End, Oracle can potentially save an ally from Primal Beast's spell combos.
* Oracle can interrupt Primal Beast's
* Primal Beast's lethal burst damage combos can be further stalled with False Promise; combined with Fate's Edict and regen from Purifying Flames, Oracle can even completely negate Primal Beast's offense.
