Drow Ranger
* Drow Ranger's lack of mobility and area-of-effect abilities makes her easy prey for Broodmother and her Spiderlings.
Oracle
* Oracle cannot easily deal with swarms of units, making him weak against heroes like 
Phantom Lancer or 
Broodmother.
Drow Ranger
* Heroes with high physical damage output but lack of reliable escape mechanisms are always a good target for a solo gank: 
Sniper, 
Shadow Fiend, 
Troll Warlord, 
Drow Ranger. Those heroes, however, are dangerous if they manage to close the gap, so take caution.
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.
Drow Ranger
* 
Phantom Rush lets Phantom Lancer get close quickly and disable Marksmanship.
* As Phantom Lancer commonly buys 
Manta Style, he can easily dispel Gust and then chase after Drow Ranger.
* Because Phantom Lancer is a natural 
Diffusal Blade carrier, he can easily burn Drow Ranger's mana and render her unable to use Frost Arrow and Gust to save herself.
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.
Drow Ranger
* 
Berserker's Call forces Drow Ranger to attack Axe up close, disabling her Marksmanship bonus.
* 
Counter Helix occurs more often with Drow Ranger's high attack speed.
* 
Culling Blade is a dangerous ability against a low health hero like Drow Ranger.
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.
Drow Ranger
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, 
Lion.
Drow Ranger
* 
Time Walk can be used to close the distance within Drow Ranger, hindering her Marksmanship bonus.
* Faceless Void can also lock down Drow Ranger with 
Chronosphere before she has the chance to retaliate due to her low health pool.
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.
Drow Ranger
* Fragile carries with no reliable escaping mechanism can be bursted down in no time: Sniper, Drow Ranger, 
Clinkz
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.
Drow Ranger
* Heroes with weaker mobility will struggle to keep up with Night Stalker: 
Gyrocopter, 
Ursa, Drow Ranger
Oracle
* Heroes with long disables, like Lion, 
Night Stalker, or 
Legion Commander, can prevent Oracle from using spells or items.
Drow Ranger
* 
Life Break closes the distance between Huskar and Drow Ranger, dealing large amounts of damage and disabling Marksmanship.
* 
Berserker's Blood and 
Burning Spear allow Huskar to beat Drow Ranger directly and pile on damage.
Drow Ranger
* 
Laser along with 
Heat-Seeking Missile allows Tinker to quickly burst down Drow Ranger due to her low health.
* Heat-Seeking Missile lets Tinker out-range Drow Ranger and hit her in the backline of a teamfight.
Drow Ranger
* Getting trapped in Power Cogs usually means the end for Drow Ranger.
Additional:
* 
Hookshot lets Clockwerk close the gap to Drow Ranger, disabling her Marksmanship bonus.
* 
Power Cogs and 
Battery Assault keep Drow Ranger from escaping.
* Power Cogs and Battery Assault also keep Drow Ranger close, nullifying Marksmanship.
Drow Ranger
* Drow Ranger's lack of escape abilities makes her an easy target for Relocate ganks.
Drow Ranger
* Nyx Assassin has a lot of burst damage from his 
Impale, 
Mind Flare, 
Dagon, and the bonus damage from 
Vendetta. All of this damage is enough to kill Drow Ranger.
* Nyx Assassin is usually invisible most of the time thanks to his ability Vendetta, which allows him to gank Drow Ranger easily.
* However, 
Gust is extremely dangerous for Nyx Assassin, as it's silence can render Nyx Assassin unable to lock down Drow Ranger. And if Gust hits Nyx Assassin while he is invisible with Vendetta, Drow Ranger will be able to detect him and foil his ganking attempts on her because Gust reveals invisible units.
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.
Drow Ranger
* Magnetic Field protects Arc Warden and allies from Drow Ranger's ranged attacks. She most likely will not enter the field since she will lose 
Marksmanship's bonus agility.
* Beware however, as Marksmanship procs will still hit since they have True Strike, so the most damaging arrows will still hit you inside Magnetic Field.
Additional:
* 
Flux along with 
Spark Wraith allows Arc Warden to quickly burst down Drow Ranger due to her low health.
* However, Drow Ranger can bypass 
Magnetic Field's evasion bonus thanks to Marksmanship.
Drow Ranger
* 
Shapeshift allows Lycan to get close and disable Marksmanship.
* Shapeshift also makes him immune to slows like Drow Ranger's Frost Arrows.
Additional:
* The Wolves's speed causes the knockback from Gust to be ineffective.
* Drow Ranger lacks escapes and loses her Marksmanship when someone is near her. Lycan can take advantage of these weaknesses of Drow Ranger.
Drow Ranger
* Drow Ranger has a very low health pool, allowing Lion to burst her down.
* Lack of any innate escape mechanism makes her an easy target for Lion's disables.
* Early on she can't deal as much damage to be life threatning. Her Gust is her best weapon against Lion.
Oracle
* Heroes with long disables, like Lion, Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
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.
Drow Ranger
* 
Meat Hook brings Drow Ranger to Pudge, disabling Marksmanship and dealing a huge amount of damage when combined with 
Rot and 
Dismember.
* Rot keeps Pudge close to Drow Ranger, continuously disabling Marksmanship.
Additional:
* Meat Hook can pull Drow Ranger to Pudge, disabling her Marksmanship.
* Following up with Dismember will prevent Drow Ranger from using Gust or 
Shadow Blade.
Drow Ranger
* A well-timed 
Dark Pact can dispel Frost Arrows and Gust, letting Slark engage and escape freely.
* 
Essence Shift is very detrimental for Drow Ranger as the loss of agility means that Marksmanship will also suffer from getting weakened.
* 
Shadow Dance lets Slark quickly close the gap and deal heavy damage without giving Drow Ranger a chance to retaliate.
* 
Pounce counteracts Frost Arrows's slow, and also allows Slark easily pin Drow Ranger down or flee from her.
* 
Depth Shroud from 
Aghanim's Shard will allow Slark to save both, himself and his allies and will also allow them to freely fight back against Drow Ranger without her noticing them.
Additional:
* Pounce and items like Shadow Blade makes it very difficult for Drow Ranger to keep her distance from Slark, thereby losing her Marksmanship bonus.
* Gust is rarely enough to keep Slark at bay, as Drow Ranger has no movement abilities and will simply be chased down afterwards.
* Drow Ranger's heavy dependence on agility also makes her significantly weaker after being drained by Essence Shift.
Drow Ranger
* Another hero heavily based on attacks and no mobility, being an easy prey for Treant strong disarms and motion reduction skills.
Drow Ranger
* Monkey King can scout Drow Ranger's positioning from the trees, and can jump on her without much trouble, disabling Marksmanship
* She lacks innate mobility to escape from Wukong's Command, whose bonus armor gives MK one extra edge in the fight
Drow Ranger
* 
Snowball and 
Ice Shards keep Drow Ranger down and preventing her from running away.
* Snowball also lets Tusk get to Drow Ranger and stop her Marksmanship bonus. It can also be to save allies affected by Gust.
* 
Tag Team allows Tusk to slow her down and land a killing blow on her.
* 
Walrus PUNCH! slows Drow Ranger and deals a huge amount of damage to her, due to her low health (and low armor without Marksmanship, since Tusk can quickly close the gap to Drow Ranger).
Drow Ranger
* 
Blink Strike gets Riki close to Drow Ranger and disable Marksmanship.
* 
Cloak and Dagger allow Riki stay close to Drow Ranger without her noticing him, which allows him to disable Marksmanship.
Additional:
* With Blink Strike, Riki can get close to Drow Ranger and disable her Marksmanship, and Smoke Screen will prevent her from using Gust.
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.
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.
Drow Ranger
* Drow Ranger's low mobility and lack of defensive abilities make her an easy gank target in the early to mid-game.
* A Dueling Drow Ranger will lose her precious Marksmanship, reduce her damage output significantly, and will more likely lose that Duel.
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.
Drow Ranger
* 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.
Drow Ranger
* 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.
Drow Ranger
* 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.
Drow Ranger
* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: Drow Ranger, 
Bane, 
Necrophos, 
Crystal Maiden.
Additional:
* 
Reality Rift will disable Drow Ranger's Marksmanship, along with 
Chaos Bolt he can keep her locked for enough time to be killed.
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.
Drow Ranger
* Heroes who rely on physical damage output to be effective will fare badly against Muerta's 
Pierce the Veil: Phantom Assassin, 
Terrorblade, Drow Ranger, 
Lifestealer, 
Anti-Mage, 
Alchemist, 
Lycan, Clinkz, Sniper.
Drow Ranger
* Mirana can use Leap to jump right next to Drow Ranger or can approach her while under cover of the invisibility granted by Moonlight Shadow, which cancels the bonus granted to Drow Ranger by Marksmanship.
* Her low health makes her easy to burst down with Mirana's spells, especially with Aghanim's Scepter.
* Mirana can dodge Gust with good reaction time, or Leap away if Drow tries to slow her without Gust.
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.
Drow Ranger
* Often you can burst Drow Ranger down before she has a chance to try and Gust you away. Try to have a teammate bait her Gust out before you Blink and get the drop on her.
Drow Ranger
* Heroes reliant on abilities to output damage or escape can be shut down by Gust: 
Queen of Pain.
Drow Ranger
* 
Static Link weakens Drow Ranger's attack damage while strengthening Razor's attack damage.
* 
Plasma Field & 
Storm Surge keeps Razor close to Drow Ranger, continuously disabling Marksmanship.
Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or 
Razor.
Drow Ranger
* As long as Mars is facing her with Bulwark, even if pushed away with Gust, Drow Ranger will do no effectual damage against him. Mars' ability to endure her onslaught usually gives him enough time to cast Arena of Blood, of which she has a very slim chance surviving without Gust.
* With Bulwark's active ability, Mars can protect allies pursued by Drow Ranger by redirecting her projectiles to his shield instead.
Oracle
* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, 
Dark Willow, 
Enigma, 
Invoker, 
Pugna, 
Skywrath Mage, 
Tinker, 
Zeus, Oracle.
Drow Ranger
* Atrophy Aura reduces Drow Ranger's damage significantly, as she relies completely on agility to be effective.
Oracle
* 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,

Drow Ranger
* A well-timed Gust will prevent Rubick from casting abilities from 
Spell Steal, and his lack of capabilities and low health pool usually dies very quickly.
* Drow Ranger can dispel 
Fade Bolt's reduction debuff with Manta Style.
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.
Drow Ranger
* Gust can hit Dark Willow beyond a defensive Bramble Maze, and before she gets close enough to hit Drow Ranger with Bedlam.
* Drow Ranger's long range allows her to hit Dark Willow's team without venturing into her Bramble Maze.
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.
Drow Ranger
* 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.
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.
Drow Ranger
* Drow Ranger can use Gust to push back Juggernaut before he can get in range to use 
Omnislash or 
Blade Fury.
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.
Drow Ranger
* Heroes with low health are especially vulnerable to Marksmanship's high damage output: Clinkz, Crystal Maiden.
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.
Drow Ranger
* Any hero that can outrange Plague Ward can neutralize them without putting themselves at risk of receiving Poison Sting: 
Arc Warden, 
Chen, Clinkz, Drow Ranger, Lina, 
Mirana, 
Nature's Prophet, Pugna and Sniper.
* Special mention to heroes that outrange Plague Ward after obtaining talents that increase attack range.
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.
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.
Drow Ranger
* A well-timed Gust will prevent Windranger from escaping or counter-initiating with 
Windrun.
* Drow Ranger commonly buys Shadow Blade or 
Silver Edge, which allows her to escape from 
Focus Fire. 
Monkey King Bar, a situational item on Drow Ranger, counters Windranger's evasion from Windrun.
* The bonus agility from Marksmanship can shred through Windranger's low armor.
Additional:
* A well-timed Gust prevents Windranger from escaping or counter-initiating with Windrun.
* Drow Ranger can combine 
Frost Arrows and 
Eye of Skadi to effectively slow down Windranger if she tries to escape with Windrun, since both slow effects stack with each other.
* Drow Ranger commonly buys Shadow Blade or Silver Edge, which allows her to escape from Focus Fire. Drow Ranger can also buy Monkey King Bar or 
Nullifier to counter Windranger's evasion from Windrun.
* The bonus agility from Marksmanship can shred through Windranger's low armor.
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.
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.
Drow Ranger
* Dragon Knight has no built-in disengage from Frost Arrows, and Marksmanship procs ignore base armor, bypassing Dragon Knight’s durability for the most part, making Drow one of the few heroes that can deal enough sustained damage to solo kill Dragon Knight.
* With Aghanim's Scepter, Frost Arrows also apply hypothermia stacks, reducing her target’s regen, which is especially potent against tanks like Dragon Knight. (A similar effect can also be achieved with an Eye of Skadi).
Drow Ranger
* A well-timed Gust will prevent Weaver from escaping, and a silenced Weaver usually dies very quickly.
* Weaver gains a lot of armor, which is bypassed by Marksmanship.
Additional:
* A well-timed Gust followed by Frost Arrows will prevent Weaver from escaping with Shukuchi. A Weaver silenced for more than 3 seconds usually dies very quickly.
* Due to her high attack speed, Drow Ranger can easily kill The Swarm beetles.
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
* 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
* 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
* Fate Edict can completely negate Skywrath Mage's heavy magic damage.
* Fortune End dispels Ancient Seal.
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.
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.
Drow Ranger
* Black Hole while definitely a threat to Drow Ranger, is very hard to land as she likes to keep her distance from allies and enemies alike. And if not caught in it, will kill Enigma very quickly due to his low health.
* 
Malefice can be removed with a Manta Style.
* Drow Ranger being a fairly low health, high armored agility carry doesn't take much damage from Midnight Pulse as others would.
* 
Demonic Conversion units die very quickly to Marksmanship or even just regular attacks not far into the game within 2 or 3 hits.
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 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.
Drow Ranger
* Gust can shut down most of Dawnbreaker's abilities, rendering her useless.
* Frost Arrows followed by a high attack speed, makes it hard for Dawnbreaker to escape.
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
* 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.
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.
Drow Ranger
* Every hero that can withstand or prevent Eclipse at level 7: 
Juggernaut, 
Riki, 
Clockwerk, Drow Ranger, Abaddon, 
Faceless Void, 
Weaver, Outworld Destroyer.
Drow Ranger
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, Templar Assassin, Arc Warden
Drow Ranger
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
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
* 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 purge his slow and disables are very difficult to go on and their team: Abaddon, Oracle.
Drow Ranger
* As a spellcaster, silences will nullify him entirely. Some notable examples are Death Prophet, Drow Ranger, Bloodseeker, 
Disruptor and many others.
* 
Doom, as usual, fits this description nicely.
Drow Ranger
* Lich is heavily reliant on his abilities to contribute to team fights, so be wary of enemies that can Silence: Bloodseeker, Death Prophet, Silencer, Drow Ranger, Skywrath Mage.
Oracle
* Heroes with dispels: Legion Commander, Oracle, 
Slark, Phantom Lancer
Drow Ranger
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet, Night Stalker, Drow Ranger, 
Doom .
Drow Ranger
* Heroes with silence: Death Prophet, Riki, Drow Ranger.
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.
Drow Ranger
* Heroes who rely on passive abilities and attacks, such as Drow Ranger, Wraith King, and 
Lone Druid, can render Silencer useless. But remember that a smart Silencer will most likely buy Silver Edge to counter this if he is played as carry.
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.
Drow Ranger
* With 4 active abilities, Shadow Shaman is weak against silencing foes such as Silencer, Drow Ranger and Death Prophet.
Oracle
* Heroes with area dispel can kill multiple skeletons at once: 
Brewmaster, Oracle.
Oracle
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom: Chen, Dazzle, Io, Oracle, Omniknight, 
Witch Doctor, Winter Wyvern, Abaddon, etc.
Drow Ranger
* Drow Ranger can be difficult to get on top of, thanks to her Frost Arrows and Gust. With these two abilities, Drow Ranger is able to effectively 'kite' Doom and minimize his impact during team fights and laning stage.
* Much of Drow Ranger's effectiveness comes from her passive Marksmanship, which is not disabled by Doom.
Drow Ranger
* 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.
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.
Drow Ranger
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, Lina, Rubick, etc.
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.
Drow Ranger
* 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.
Drow Ranger
* 
Metamorphosis will not match the range of Drow Ranger and he will struggle to do damage to her if she is not locked down already by someone else.
* 
Conjure Image will be destroyed very quickly due to Marksmanship.
* Terrorblade generally likes to be the big bad late game carry who sits in the middle of the fight and kills whoever is closest, which is very unlikely to be Drow Ranger therefore making it likely she will be going on him in teamfights.
* Terrorblade's high base armor and agility items makes him very vulnerable to Marksmanship.
Additional:
* Even though Drow Ranger's damage output is 100% physical, Marksmanship allows Drow Ranger to pierce Terrorblade's high natural base armor and when upgraded with Aghanim's Scepter, it will allow her to clear Terrorblade's illusions.
* Gust can prevent Terrorblade from using 
Sunder.
* Since Terrorblade doesn't like to buy armor items like 
Assault Cuirass, he will be very vulnerable to Drow Ranger's high physical burst damage.
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.
Drow Ranger
* None of Anti-Mage's skills are that effective against Drow Ranger. Gust prevents him from Blinking in or out, Counterspell is totally useless against Drow's physical damage, and as she usually doesn't have a high mana pool, Mana Break and Mana Void don't do much either.
* Be careful however that Anti-Mage may eventually farm enough to Blink on top of you and kill you straight away, considering you have no natural tools to escape from him.
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.
Drow Ranger
* Clinkz has no stun and likes to keep his distance from targets, making Marksmanship very deadly.
* Clinkz also has low health, making him a perfect hero to initiate onto with Gust.
* Gust can also prevent Clinkz from using 
Burning Barrage.
Drow Ranger
* Heroes who depend on attacks (such as Shadow Fiend or Drow Ranger) can be nullified by Fire Spirits' attack speed slow.
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.
Drow Ranger
* 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.
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.
Drow Ranger
* Range-reliant heroes: Sniper, Drow Ranger
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.
Drow Ranger
* Heroes who outrange Drow Ranger such as Sniper, Tinker.
Oracle
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or Razor.
Drow Ranger
* 
Repel can be used to dispel Gust on the allies affected by it.
* In team fights, 
Guardian Angel renders Drow Ranger's physical damage useless, and Drow Ranger has no way to purge it. And to make thing worse, Drow Ranger is not a common Nullifier wielder to counter this problem at all.
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.
Drow Ranger
* Invisible heroes are very difficult for Drow Ranger to deal with such as 
Bounty Hunter, Riki and heroes who commonly buy a Shadow Blade.
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.
Drow Ranger
* Low-health, normally mobile carries who rely entirely on raw attack damage are vulnerable to Bane's nukes and disables: Anti-Mage, Clinkz, Drow Ranger, Faceless Void, Gyrocopter, Juggernaut, 
Meepo, Mirana, Monkey King, Morphling, Phantom Assassin, Phantom Lancer, Riki, Shadow Fiend, Slark, Sniper, Terrorblade, Troll Warlord, Weaver.
Oracle
* Heroes with strong dispels can dispel Bane's disables from their allies: Oracle, Legion Commander, Omniknight.
Drow Ranger
* Morphling can use Waveform to close the gap between him and Drow Ranger, but should be careful of Gust and Frost Arrows.
* Morphling is a natural Manta Style carrier, which dispels the silence from Gust.
Drow Ranger
* 
Attribute Shift (Strength Gain) may not be quick enough to fend off an attacking Drow Ranger.
* Morphling likes to sit on low health with high agility, something Drow Ranger does not particularly care for and will still hit him hard with Marksmanship procs.
* 
Morph is a similar story, none of Drow Ranger's spells are particularly good against her.
Drow Ranger
* Spectre can easily close the distance on Drow Ranger with
Haunt and stick on her with 
Spectral Dagger, effectively disables her 
Marksmanship.
Gust, since Spectre will catch her up regardless.
Dispersion can reflect some damage back to Drow Ranger should she chooses to attack.
Silver Edge as an attempt to shut you down.
* Spectre does not care if silenced by
*
* Be careful once she got her
Oracle
* Oracle's burst damage is ineffective against
Dispersion.
Dispersion.
Fate's Edict does not hinder Spectre that much, since she can deal damage even without landing a single attack.
* 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
* Disarm from
