Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (
Clinkz, 
Templar Assassin, 
Ursa, 
Wraith King etc).
Oracle
* Heroes who can take advantage of Oracle's low mobility or catch him out of position, such as Clinkz and 
Anti-Mage, can easily pick him off.
Tiny
* 
Chaos Bolt and 
Reality Rift makes Tiny's low mobility non existent.
* 
Chaos Strike means Chaos Knight will most likely survive longer in a duel between the two because Tiny has much lower attack speed.
* Chaos Knight has a 3.2 strength growth, making him one of the most tanky heroes and a very difficult target for Tiny to burst.
Oracle
* Oracle's burst damage is ineffective against 
Dispersion.
* Disarm provided by Fate's Edict is not as significant debilitation for Spectre as it might be for other carries since She can do damage even without landing attacks.
Additional:
* Oracle's burst damage is not enough to take down Spectre due to Dispersion.
* Disarm from 
Fate's Edict does not hinder Spectre that much, since she can deal damage even without landing a single attack.
Tiny
* Tiny has low movement speed and attack speed, making him vulnerable to Viper's slows.
* 
Corrosive Skin provides magic resistance to lower Tiny's magic burst damage.
Oracle
* False Promise will not save an ally from 
Culling Blade if their health is low enough.
* Fate's Edict, offensively or defensively, does little to protect Oracle's allies from the majority of Axe's damage.
Tiny
* 
Feast will deal a enormous amount of damage because of Tiny's huge health pool.
* 
Rage protects Lifestealer from Tiny's magical burst damage.
Oracle
* 
Disruption can protect Shadow Demon's allies from Fortune's End, preserving healing or buffs. It can also catch Oracle's allies, allowing 
Shadow Poison to be used without being dispelled.
* 
Demonic Purge prevents over-time healing during False Promise, such as Purifying Flames and 
Urn of Shadows. If he has 
Aghanim's Scepter, this issue can persist for longer or on multiple allies.
* It will not, however, prevent healing from instant abilities, items, or auras, making 
Mekansm a good choice against him.
Tiny
* Familiars will easily be able to kite heroes with a short range or with low attack speed. For example, 
Tiny and 
Undying have a very hard time killing Familiars.
Oracle
* Because Oracle uses few, powerful instances of damage to kill enemies, Templar Assassin's 
Refraction and 
Visage's 
Gravekeeper's Cloak can absorb his burst damage.
Tiny
* Tiny can deal with Visage's Gravekeeper's Cloak quickly, as Avalanche deals damage in enough instances to completely remove all 4 layers of the passive. With Visage's lower than average Armor, a well positioned stun can allow Tiny to kill Visage easily.
Additional:
* Tiny's 
Avalanche removes a significant number of layers from Gravekeeper's Cloak. When combined with 
Toss burns through all of Gravekeeper's Cloak while doing triple times Toss damage to Visage in midair.
* Tiny's already high damage coupled with 
Tree Grab's attack modifier will make short work of Visage's Familiars.
Oracle
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as 
Timbersaw, or those who can dispel them, such as 
Phantom Lancer, can kill Oracle unhindered.
Oracle
* Heroes with long disables, like 
Lion, 
Night Stalker, or 
Legion Commander, can prevent Oracle from using spells or items.
Tiny
* Heroes with naturally low mana can be easily shut down by E.M.P.: 
Sven, Tiny, Wraith King, 
Omniknight
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like 
Phantom Assassin and 
Tinker are very effective because of Tiny's low attack speed. Additionally, 
Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Oracle
* 
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.
Tiny
* He can quickly take out heroes with low armor (Tiny) with his great physical damage.
Tiny
* 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.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Oracle
* Because Oracle uses few, powerful instances of damage to kill enemies, Templar Assassin's Refraction and Visage's Gravekeeper's Cloak can absorb his burst damage.
Tiny
* Heroes that have disposable area-targeted spells can force her to undo her Meld: 
Leshrac, 
Puck, Tiny, 
Jakiro,. An experienced Templar Assassin could try to use Refraction before Meld so she can tank through those damage without getting her Blink disabled.
Oracle
* Anti-Mage can withstand magical burst damage much better than other carries, making him effective against nukers: 
Lich, 
Necrophos, 
Oracle, and Leshrac.
Additional:
* Oracle has minimal damage potential against Anti-Mage due to 
Counterspell, and may even have some ability damage reflected at himself.
* Anti-Mage can easily overwhelm Oracle with 
Mana Break and 
Mana Void.
* 
Blink allows Anti-Mage to easily chase and take advantage of Oracle's low mobility.
Tiny
* Heroes that are able to slow Tiny's attack speed, like 
Tusk and 
Phoenix, will greatly limit his Physical damage output.
Tiny
* Long ranged heroes like 
Sniper or 
Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Tiny
* Heroes with high base damage (
Morphling, Tiny, Drow Ranger), heroes with mana burning abilities (Anti-Mage), and 
Diffusal Blade users (
Juggernaut or 
Riki) will suffer from Reflection's illusions.
Oracle
* Heroes who are not easily crippled by Fate's Edict or Fortune's End, such as Timbersaw, or those who can dispel them, such as Phantom Lancer, can kill Oracle unhindered.
Tiny
* Avalanche and Toss will never be enough damage to take out Sven in a clean way.
* Tiny is very slow with low armour growth and does not buy items to sustain Sven's damage output.
Oracle
* Fate's Edict cripples many heroes who rely on attacks, such as Phantom Assassin, Sven, or 
Enchantress, without a dispel or a 
Black King Bar.
Oracle
* 
Time Walk and 
Backtrack allow Faceless Void to easily negate Oracle's burst damage.
* 
Time Dilation is effective against Oracle's low-cooldown spells. Although dispellable with Fortune's End, it can still catch Oracle off guard if Fortune's End is on cooldown.
* However, False Promise is one of the best abilities in the game to delay or even potentially save any ally caught in 
Chronosphere. Combined with Fate's Edict, a well-positioned Oracle denies Faceless Void and his team from attempts at solo-Chronosphering key targets to open up a teamfight.
Oracle
* Any hero that can nullify effects of Chronosphere: (
Keeper of the Light with Aghanim's Scepter during daytime, 
Winter Wyvern), banishing him or Faceless Void (
Outworld Destroyer, 
Shadow Demon, 
Earth Spirit with Aghanim's Scepter) or protecting him in other ways (
Dazzle, Oracle, 
Abaddon) can greatly limit Chronosphere's potential.
Tiny
* 
Blade Fury protects Juggernaut from all of Tiny's magic burst damage.
Oracle
* Heroes with abilities that can save teammates are also effective such as Shadow Demon, Dazzle, Oracle, 
Bane, 
Pugna, Tusk, Winter Wyvern, 
Io, 
Underlord, 
Treant Protector and Keeper of the Light.
Tiny
* Squishy heroes, usually supports, like Lion, 
Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Oracle
* 
False Promise can dispel the stun from Cold Feet and can save an ally that's about to shatter from Ice Blast, even allowing healing with 
Purifying Flames by delaying it until after the debuff expires.
* Purifying Flames allows Oracle to deny his allies if they're affected by Ice Blast. If he brings his allies' health to or below the shatter threshold, it will count as him denying the ally. However, this does not work on Oracle himself.
* Fate's Edict provides 100% magic resistance, making it good against all of Ancient Apparition's abilities at all stages of the game.
* 
Fortune's End can dispel Cold Feet from allies.
Additional:
* False Promise can prevent the shatter from 
Ice Blast and Fate's Edict can protect an ally from the magical damage over time for a while.
* Oracle can deny allies who are frostbitten. If he uses Purifying Flames to reach the shatter threshold, it will count as a deny.
* Fortune's End can dispel 
Cold Feet on affected allies, preventing them from getting frozen.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Oracle
* Heroes with dispels: Legion Commander, Oracle, 
Slark, Phantom Lancer
Tiny
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, 
Ogre Magi.
Oracle
* Heroes that can purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Oracle
* False Promise dispels Flaming Lasso.
* Fortune's End can root Batrider after he uses Flaming Lasso. It can also dispel Sticky Napalm and Flamebreak.
* Fate's Edict when used on a Lasso'd target will leave them immune to magical damage, making it difficult to burst them quickly before the Lasso ends.
Oracle
* Oracle can shut down both of Ember's early game abilities. Fortune's End can dispel 
Flame Guard on Ember Spirit and 
Searing Chains on allies.
* When Ember Spirit is affected by Fortune's End, his 
Fire Remnants move at 0 movement speed.
* Disarming him with Fate's Edict does affect Ember's 
Sleight of Fist ability, possibly making him useless for a few seconds in the late game without a dispel or spell immunity. This is especially good if he has a rapier or two. However, positioning for this is difficult when Ember plays far back.
Oracle
* Oracle's high magic damage output can easily take down Rubick's low health pool.
* Because Oracle can combo spells in rapid succession (due to low cooldowns), it may be difficult for Rubick to 
Spell Steal False Promise. This scenario can even be avoided by shift queueing Fortune's End and casting it immediately, as it has no cast point, or by staying in the back line of fights if out of mana.
* As a position based hero, Rubick will have a very hard time against Fortune's End due to its absurd range and very long root duration.
Oracle
* 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.
* Oracle can dispel 
Reactive Tazer off Techies, as well as the silence from 
Blast Off!, with Fortune's End.
* Oracle can further delay Techies' burst damage capability with False Promise.
Additional:
* Fate's Edict gives 100% magic resistance, which prevents most of Techies' damage.
* Oracle's 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.
* 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.
Oracle
* Oracle's Fate's Edict will protect an ally from Leshrac's nuking damage.
* Oracle's False Promise can dispel Leshrac's stun and slow from his abilities, allowing an ally to escape.
* Fortune's End can stop Leshrac from chasing opponents or running away.
Oracle
* Fortune's End dispells Marci's 
Sidekick, removing additional damage and lifesteal.
* Fate's Edict disarms Marci, preventing her from attacking with 
Unleash. Also it is useful against Marci or her ally affected by Sidekick.
* False Promise is a great tool to save an ally focused by Marci.
Tiny
* Toss and Avalanche deals heavy damage to Slark in the early game, making Tiny a very dangerous target to gank.
* Tiny has 0 agility, which means Slark's 
Essence Shift permanent agility steal does not do much against him.
Oracle
* Fortune's End not being disjointable is almost an ensured disable if Dark Willow tries to escape with Shadow Realm. Dispels Cursed Crown and Terrorize.
* Fate's Edict negates all her magic damage in case she catches a single hero.
* 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.
Oracle
* Fate's Edict gives full immunity from Ogre Magi's mostly magical damage.
* Fortune's End can dispel Ignite (when used on allies) and Bloodlust (when used on enemies).
* False Promise can dispel Ignite and Fireblast.
Oracle
* All of Pugna's damage is magical, which can get blocked by Fate's Edict's 100% magic resistance.
* Oracle has two abilities that apply a dispel, which can easily remove Decrepify on his ally or Oracle.
Oracle
* Fate Edict can completely negate Skywrath Mage's heavy magic damage.
* Fortune End dispels 
Ancient Seal.
Oracle
* 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.
* Oracle can interrupt Primal Beast's 
Onslaught charge with a well-timed Fortune's End.
* 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.
Additional:
* 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 Pulverize, 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
* It is especially easy for Oracle to negate the damage from Maledict, and even heal through it with Fate's Edict and Purifying Flames.
* If by some miracle an enemy is still about to die because of Maledict, he can still save him with False Promise.
Oracle
* Fortune's End dispels Ion Shell and Surge, making any gank attempt on Dark Seer in the laning phase likely to succeed.
* Fate's Edict prevents all magical damage that comes from Dark Seer's abilities.
* Fortune's End dispels Ion Shell on creeps, which Dark Seer relies on to farm and zone.
Additional:
* Fortune's End can dispel 
Ion Shell, a skill that helps Dark Seer immensely in the laning phase, as well as 
Surge, a move-speed buff, effectively allowing Oracle to control Dark Seer, especially in the laning phase.
Tiny
* Avalanche and Toss combo makes short work of 
Mirror Image's illusions.
* Tiny's cleave with Tree Grab and area of effect damage with Tree Volley will easily wipe out illusions.
Oracle
* Fortune's End's AoE dispel will remove Heavenly Grace and Guardian Angel.
Additional:
* Oracle can dispel 
Heavenly Grace (which he can also bait out with Fate's Edict).
* With Fortune's End, Oracle can dispel 
Guardian Angel in an area of effect.
Oracle
* Fate's Edict can disarm Troll, rendering him useless in a teamfight, especially if he has already used Battle Trance.
* Fortune's End and Purifying Flames can provide ample magic damage to help burst down Troll Warlord quickly in the early to mid game.
* False Promise can save an ally from Troll Warlord's initiation, forcing him to switch targets and lose his Fervor stacks, or waste time during Battle Trance.
Oracle
* Fortune's End applies a basic dispel which can be used to dispel Corrosive Haze, or even Slardar's own Guardian Sprint.
* False Promise is able to dispel Corrosive Haze and Slithereen Crush stun/slow from any allies Oracle chooses to cast it on.
* Fate's Edict can also be cast on Slardar to prevent him from proccing his Bash of the Deep.
Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as 
Skywrath Mage, 
Crystal Maiden, or Enchantress.
Oracle
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, 
Enigma, 
Invoker, Pugna, Skywrath Mage, Tinker, 
Zeus, Oracle.
Oracle
* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.
Oracle
* 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.
Oracle
* Heroes that can protect or dispel stunned allies such as Legion Commander, Outworld Destroyer, Shadow Demon and Oracle can reduce the effectiveness of Sacred Arrow.
Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.
Oracle
* Oracle with Fortune's End and False Promise
* Heroes that can remove the Track debuff with their skills:
* Abaddon with 
Aphotic Shield and 
Borrowed Time
* Huskar with 
Life Break
* Juggernaut with Blade Fury
* Legion Commander with 
Press the Attack
* 
Lifestealer with Rage and 
Infest
* Naga Siren with Mirror Image
* Omniknight with Heavenly Grace
* Oracle with Fortune's End and False Promise
* Phantom Lancer with 
Doppelganger
* Slark with 
Dark Pact
* Ursa with 
Enrage
* 
Weaver with 
Time Lapse
* Tidehunter with 
Kraken Shell when damage received reaches the threshold.
Oracle
* Heroes with strong dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight.
Oracle
* Fortune's End and False Promise easily dispel many crippling debuffs, such as Venomancer's 
Venomous Gale, or Skywrath Mage's Ancient Seal.
Additional:
* Fortune's End can dispel Venomous Gale and Poison Sting from allies.
* Fate's Edict grants 100% magic resistance to target, inhibiting the damage from Venomancer abilities.
Tiny
* Tiny's Avalanche affects all Meepos and Toss can send a singular Meepo into death.
Additional:
* Avalanche and Toss prevents Meepo's from using 
Poof to escape.
* Tiny doesn't need to target the weakest clone while he is affected by Tree Grab.
Tiny
* Heroes that are able to slow Tiny's attack speed, like Tusk and Phoenix, will greatly limit his Physical damage output.
Oracle
* Phoenix does significant magic damage over time which can either be dispelled or negated by Fate's Edict.
* Oracle's burst damage potential can prove lethal to Phoenix, as they already have to sacrifice health to cast their basic skills.
Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Oracle
* Fate's Edict prevents Legion Commander from attacking for a few seconds, potentially saving Oracle's ally.
* Fortune's End dispels Press the Attack's healing and attack speed buff, as well as the movement speed bonus from Overwhelming Odds.
* False Promise protects allies and prevents Legion Commander from winning Duels and gaining bonus damage.
Additional:
* Provided that the enemy team does not have an 
Axe, Oracle can guarantee that his ally survives for the duration of the Duel with False Promise and has decent nuke potential to help ally to win a Duel. He can also disarm Legion Commander with Fate's Edict.
* Oracle can dispel enemy buffs like 
Overwhelming Odds and Press the Attack with Fortune's End.
Oracle
* Oracle cannot easily deal with swarms of units, making him weak against heroes like Phantom Lancer or 
Broodmother.
Tiny
* Tiny can quickly clear Spiderlings with his active abilities and cleave.
Oracle
* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle, Oracle, 
Warlock.
Oracle
* Heroes with the ability to heal allies, or those with good defensive abilities: 
Chen, Dazzle, Io, Oracle, Omniknight, 
Witch Doctor, Winter Wyvern, Abaddon, etc.
Tiny
* 
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.
Additional:
* Lion can continuously Mana Drain Tiny in the early game, depleting his small mana pool for his abilities.
Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Tiny
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Oracle
* Lion is extremely dependent on his abilities. Silences like 
Silencer's 
Last Word, magic resistance like Oracle's Fate's Edict, and dispels like Legion Commander's Press the Attack all make his abilities less effective.
Tiny
* Primal Roar and the slow from Boars make kiting Tiny very easy.
Oracle
* False Promise effectively nullifies Primal Roar's single-target initiation on allies.
* Purifying Flames kills Beastmaster's Hawk instantly and Boar with two casts.
Tiny
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.
Oracle
* Oracle's reliance on spamming his spells can be easily hindered by Silencer's Arcane Curse.
* Last Word and Global Silence negates Oracle's attempt to save his allies with his spells.
* Fate's Edict is useless against Glaives of Wisdom's pure damage.
Oracle
* Fortune's End can nullify 
Arcane Curse, Last Word, and 
Global Silence, if cast at the right time with the right targets.
* Fate's Edict can prevent Silencer from attacking, which he relies on with 
Glaives of Wisdom, for a lot of his damage.
Tiny
* 
Reaper's Scythe will turn Tiny's high health against him.
* 
Heartstopper Aura does substantial damage to Tiny as a result of his high max health.
* 
Ghost Shroud protects Necrophos from Tiny's physical damage with Tree Grab and Tree Volley.
Oracle
* During the laning stage, Oracle's Purifying Flames nullifies any damage that Heartstopper Aura might inflict.
* Fate's Edict and False Promise can protect an ally from Reaper's Scythe.
* Oracle can dispel Ghost Shroud with Fortune's End.
Additional:
* Fortune's End can dispel Ghost Shroud, negating the skill's utility. Also it's worth noting that Necrophos takes additional magic damage when in Ethereal state, which makes Purifying Flames a powerful nuke against him.
* Fate's Edict fully negates the damage from Reaper's Scythe, which its own delayed animation makes it relatively easy to predict and nullify.
Tiny
* Dual Breath and Liquid Fire reduces Tiny's already abysmal Attack Speed.
* If Tiny Tosses a hero onto Jakiro, he can react with Ice Path, and potentially Macropyre.
* Tiny's Avalanche is easily countered with Ice Path.
* As Tiny has a very high Health, Liquid Frost is particularly effective against him.
Oracle
* Fate's Edict allows Oracle to make allies spell immune, allowing him to save allies from Jakiro's spells.
* Fate's Edict can be cast onto Jakiro to disarm him and prevent him from pushing with his Liquid Fire.
* False Promise allows Oracle to free allies from Jakiro's Ice Path.
Tiny
* Due to Tiny's non-existent agility gain, high physical damage heroes are more effective against him (Clinkz, Templar Assassin, Ursa, Wraith King etc).
Oracle
* Heroes with area dispel can kill multiple skeletons at once: 
Brewmaster, Oracle.
Tiny
* Heroes with Evasion or abilities that cause Tiny to miss like Phantom Assassin and Tinker are very effective because of Tiny's low attack speed. Additionally, Monkey King Bar is not a good item for Tiny because of its reliance on high attack speed to proc for magical damage.
Oracle
* Fate's Edict cripples many heroes who rely on attacks, such as Phantom Assassin, Sven, or Enchantress, without a dispel or a Black King Bar.
Tiny
* Tiny's nonexistent armor in the early game makes him very vulnerable to
Quill Spray's large amounts of physical damage.
Bristleback decreases Tiny's high burst damage against Bristleback.
Viscous Nasal Goo can slow Tiny to a crawl and allows Bristleback to easily kite him with his high movement speed and Quill Spray's long range, as Tiny has no ability to escape.
*
*
Oracle
* Fortune's End cannot dispel
Warpath stacks on Bristleback or 
Quill Spray stacks on allies.
Bristleback can heavily reduce Oracle's damage output. With it, Oracle may accidentally heal Bristleback with Purifying Flames, especially if Bristleback has bonus magic resistance.
*
