Riki
* Heroes who are reliant on physical damage will be nullified by Decrepify: 
Riki, 
Wraith King, 
Juggernaut.
Dazzle
* Pugna can turn out to be an effective hero against Dazzle due to the fact that he does not allow him to extend his 
Poison Touch with his 
Decrepify, which is why Dazzle cannot keep the enemy under prolonged deceleration.
* Pugna has a very strong ability against casters with a small health reserve - 
Nether Ward, which is why heroes like Dazzle will not be able to constantly throw their Poison Touch 
Bad Juju and 
Shadow Wave at enemies under the action of Nether Ward or will be forced to take a lot of damage

Riki
* Zeus's 
Lightning Bolt and 
Thundergod's Wrath provides a short duration of True Sight, revealing Riki while possibly dealing a heavy amount of damage.
* Zeus's 
Nimbus can be placed directly on top of 
Tricks of the Trade, potentially causing him to be damaged, stunned, and revealed the instant he becomes targetable again.
Dazzle
* Some heroes with extreme range, like 
Zeus, 
Invoker or 
Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Riki
* 
Blink Strike does not grant Riki a mobility advantage over Phantom Assassin, as her Phantom Strike serves the same purpose, but with a higher range.
* A Carry Riki usually has a hard time dealing with Blur, as a 
Monkey King Bar or 
Bloodthorn are unfavourable item picks for him (or, even more unlikely, a 
Silver Edge).
* A 
Black King Bar is a very common pick for Phantom Assassin, fully countering 
Smoke Screen and 
Diffusal Blade while activated.
Dazzle
* Dazzle's lack of a true disable makes him a relatively vulnerable target for Phantom Assassin.
* Coup de Grace will often kill Dazzle's teammates before he has a chance to use 
Shallow Grave.
Dazzle
* Hex abilities prevent attacking, ability and item usage, which is a severe problem for Phantom Assassin as it prevents her from using Black King Bar, the one item that helps protect her against the aforementioned dangers. 
Doom and 
Shadow Demon with 
Aghanim's Scepter also disables Phantom Assassin's Evasion and Critical Strike, removing much of her damage and survivabaility: Doom, 
Disruptor with Aghanim's Scepter, 
Dazzle with 
Aghanim's Shard
Riki
* With Aghanim's Scepter, Broodmother will gain access to 
Spinner's Snare, which will allow her to create invisible lines on her webs from 
Spin Web that will root, deal damage over time, and reveal enemy heroes if they unwittingly step on them. This allows Broodmother to keep her allies alerted on heroes who rely on invisibility-themed and movement-themed abilities and items to surprise enemy heroes and disrupt ganking attempts of enemy heroes: 
Phantom Assassin, 
Nyx Assassin, 
Mirana, 
Bounty Hunter, 
Templar Assassin, Riki, 
Spirit Breaker, 
Anti-Mage, 
Tusk, 
Ursa, 
Nature's Prophet, 
Enigma, 
Void Spirit, 
Magnus etc.
Dazzle
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: 
Shadow Shaman, 
Visage, Dazzle, 
Rubick, 
Lich.
Riki
* Riki takes a lot of damage from 
Purification while ganking Omniknight's allies or himself.
* 
Heavenly Grace instantly purges the slow from Diffusal Blade, while also providing a large amount of survivability for his victim.
* 
Degen Aura can hinder Riki's positioning tactics and put a heavy toll on Riki's already poor movement speed.
* Omniknight can easily save his allies by using 
Guardian Angel in combat.
Riki
* 
Pit of Malice prevents Riki from casting Blink Strike. or Tricks of the Trade.
* 
Atrophy Aura reduces Riki's damage.
* 
Firestorm can be used to harrass Riki in lane.
Riki
* With Dark Ascension and Gem of True Sight, Night Stalker can easily find and kill Riki. Riki will also find it harder to kill the tanky Night Stalker than he would many other heroes.
Dazzle
* 
Astral Imprisonment is a versatile nuisance:
* If it is cast on a low-enough-health unit at least 1 second into Shallow Grave's duration, the Shallow Grave will end during the imprisonment, and the target will take lethal damage when released.
* It can be used remove Dazzle from the fight at a time he could have saved someone.
* It lets himself or an ally dodge all of Poison Touch's effects, for long enough to recover their 
Blink Dagger.
Riki
* Viper's 
Nethertoxin disables 
Cloak and Dagger, negating Riki's invisibility and much of his damage. It also makes him more vulnerable to magic damage, which does not go well with Riki's low health pool. With the talent applied, he can't even blink to safety or hide with Tricks of the Trade.
* 
Corrosive Skin makes it hard for Riki to chase Viper and attack him due to the attack speed slow.
* 
Viper Strike stays on Riki even after he goes invisible.
* 
Poison Attack makes it risky for Riki to get last hits and can make the laning phase difficult for him.
Riki
* Riki can easily be caught in an Ice Path and Macropyre combo as he finishes Tricks of the Trade, Jakiro just has to be careful about Riki's Smoke Screen when dealing with Riki.
Riki
* 
Static Link drains away Riki's damage while keeping his location revealed for its duration, allowing his team to accurately land detection or area-of-effect skills.
* 
Storm Surge procs on invisible heroes, making him aware of Riki's presence near him.
Riki
* 
Corrosive Haze works much like 
Track, giving the enemy team vision over Riki. While it doesn't give a movement speed or gold bonus, it instead can melt Riki's armor and Slardar can use 
Guardian Sprint to catch up to him.
* Slardar's Aghanim's Shard, causes 
Slithereen Crush to apply Corrosive Haze even if Slardar does not have vision over him.
Additional:
* Corrosive Haze makes Riki completely vulnerable to Slardar and his allies, as Riki has no easy way of dispelling it.
* Slardar's physical damage with Slithereen Crush and Bash of the Deep amplified by Corrosive Haze can easily kill Riki.
Riki
* Riki does little damage to Dragon Knight, as he relies only on physical damage with modest attack speed and lack of burst.
Riki
* Quill Spray will hit Riki even when he is invisible.
* Cloak and Dagger's bonus backstab damage is rendered irrelevant against Bristleback.
* Smoke Screen does not stop Bristleback's passive from activating.
* Due to Bristleback's natural tankiness, he is an ideal 
Gem of True Sight carrier, directly countering Riki's invisibility.
Additional:
* The bonus Backstab damage from Cloak and Dagger is rendered irrelevant with 
Bristleback and hurts Riki more than him because of the passive Quill Spray.
* Riki can still get damaged by Bristleback's 
Quill Spray while invisible, and it can be hard to deal with in lane.
* Bristleback is not too bothered by Smoke Screen. Though he cannot use Quill Spray manually inside it, it still procs passively when he takes damage from the back. The movement speed from 
Warpath allows him to get out of the area easily.
* Due to Bristleback's natural tankiness, he is an ideal Gem of True Sight carrier.
* Riki rarely buys Silver Edge to break Bristleback's passive because the invisibility aspect of it is redundant.
Dazzle
* Doom can completely shut down Dazzle through 
Doom, as it prevents him from casting his abilities and, by extension, gaining Bad Juju stacks.
Dazzle
* 
Juxtapose and 
Doppelganger conjures too many illusions for Dazzle to deal with, given he has no inherent movement- or AoE-abilities.
* However, this can be partially solved with Aghanim's Shard-upgraded Poison Touch, as the hex instantly destroys illusions in an area as well as revealing the real Phantom Lancer when he's hiding among his army of illusions.
* 
Phantom Rush and 
Spirit Lance allow Phantom Lancer to trivially catch Dazzle even in the back line of a fight.
* Phantom Lancer has high base armor which counters Dazzle's physical damage based spells in lane.
* Diffusal Blade a natural item from Phantom Lancer can drains mana, which can be a problem for Dazzle, as all of his abilities have a high mana cost.
Riki
* Invisibility reliant heroes: Heroes with invisibility abilities or those that have invested into invisibility items are hindered by Bounty Hunter's Track. Few examples of such heroes are:
Clinkz, Riki, 
Treant Protector, etc.
Additional:
* Track reveals Riki while invisible and gives him a hard time, as it prevents much of his ganking capabilities. This can force Riki to buy 
Manta Style to dispel it.
Riki
* Thirst detects Riki whenever his health is low.
* Rupture does large damage when Riki uses Blink Strike.
Dazzle
* 
Bloodseeker's 
Thirst, 
Rupture, and huge AoE silence 
Blood Rite can fare well against Dazzle.
Dazzle
* Shallow Grave prevents Bloodseeker from replenishing his health by finishing off enemies.
Dazzle
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (
Lina, 
Lion, etc.)
Additional:
* Laguna Blade can kill Dazzle quickly before he casts Shallow Grave.
Riki
* Heroes with high mobility can be prevented from using it to their advantage with Earthbind, even if they pack a dangerous arsenal: 
Earth Spirit, 
Ember Spirit, 
Storm Spirit, Nature's Prophet, Phantom Assassin, Riki, Anti-Mage, 
Weaver.
* See items and abilities disabled by roots
Additional:
* Root is a deadly threat to Riki, disabling both Blink Strike and Tricks of the Trade while making him fully revealed, making 
Earthbind a good ability against him.
* Smoke Screen may not be able to silence all the Meepo clones.
* Riki has no true area damage, as Tricks of the Trade's damage is distributed between all Meepo clones, so he cannot effectively fight Meepo or deal with his strong ability to push unless Riki has 
Battle Fury.
Riki
* Riki doesn't deal burst damage.Durable heroes (
Axe, 
Tidehunter etc.) will usually survive a jump from him,move out of Smoke Screen and potentially retaliate.
Dazzle
* Heroes with high burst damage through their physical attacks or spells can kill Dazzle or his allies before he has a chance to use Shallow Grave. (Lina, Lion, etc.)
Riki
* 
Spectral Dagger follows Riki even after he goes invisible and stays on him through Tricks of the Trade, revealing his location.
* 
Desolate grants Spectre the ability to damage Riki with right clicks regardless of Smoke Screen's blind.
* Riki relies on his high damage to kill is opponents, which is countered by 
Dispersion.
* 
Haunt can find Riki globally at any time, negating much of his ganking potential.
Dazzle
* Spectre's entire ability set is designed to get to and destroy heroes that stay in the backlines, both carries (like the aforementioned 
Drow Ranger and 
Sniper) and supports (like Dazzle and Shadow Shaman).
Riki
* Riki's Smoke Screen can make it hard for Spectre to escape or burst down Riki with auto attacks.
* Riki can build Aghanim's Scepter and jump inside an allied carry or offlane tank with Tricks of the Trade to do a lot of damage to Spectre while completely avoiding Dispersion.
* Riki is great at destroying supports which are often needed to keep Spectre safe until she comes online. He can take them down quickly in team fights, which will leave Spectre alone against your whole team, a fight that she will most likely not win.
* While on Tricks of the Trade, Riki does not take damage from Dispersion.
Riki
* 
Ensnare prevents using any kind of movement abiilties, Making Naga Siren good against heroes who rely on gap-closing abilities to escape: Phantom Assassin, Magnus, 
Slark, Riki, 
Faceless Void, Storm Spirit.
Dazzle
* 
Mirror Image's illusions can easily walk straight at Dazzle and attack him, due to Dazzle's lack of reliable AoE nukes or disables.
* Ensnare roots Dazzle or his allies, making it harder to stay in range of Dazzle's saving abilities.
* 
Song of the Siren can be used to initiate a fight with superior positioning, potentially zoning Dazzle's high-impact spells out of the fight.
Dazzle
* Dazzle can instantly destroy all of Naga Siren's illusions from Mirror Image with Aghanim's Shard upgraded Poison Touch used on her or any of her illusions.
Riki
* 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.
Dazzle
* A well-timed 
Global Silence prevents Dazzle from saving allies with Shallow Grave or Shadow Wave. Items that could dispel the silence are expensive, and difficult for Dazzle to farm from a support role.
* 
Arcane Curse and 
Last Word cause long damage over time, which may outlast Shallow Grave.
Riki
* Heroes with damage-increasing passive abilities, such as 
Viper and Riki, will usually kill Silencer in a short time before he even has time to set up his abilities.
Riki
* Luna can push very fast with Moon Glaives, which is something Riki cannot deal with well.
* Luna is naturally very fast, making it hard for Riki to trap her in Smoke Cloud.
* Even though Riki can evade 
Eclipse with his invisibility, smart Luna will always buy 
Dust of Appearance, providing vision on Riki to her allies and herself.
Additional:
* Luna can push very fast with Moon Glaives, which is something Riki cannot deal with well.
* Luna is naturally very fast, making it hard for Riki to trap her in Smoke Cloud.
* Even though Riki can evade Eclipse with his invisibility, smart Luna will always buy Dust of Appearance, providing vision on Riki to her allies and herself.
Riki
* All assassin-type carries in a one against one situation: 
Meepo, Phantom Assassin, Riki, Ursa. Luna's only chances are that she buys 
Ethereal Blade or Black King Bar to gain a slight edge against them, or both items if necessary.
Dazzle
* Although 
Counterspell's passive component doesn't protect Anti-Mage from the physical damage nukes from Poison Touch and Shadow Wave, a well-timed use of it will reflect Poison Touch back to Dazzle, slowing him in the process.
* This can be even more dangerous if Dazzle has an Aghanim's Shard, as Counterspell will reflect the hex back to Dazzle.
* 
Mana Break drains mana, which can be a problem for Dazzle, as all of his abilities have a high mana cost. This makes him especially vulnerable to 
Mana Void.
Riki
* Heroes with abilities or items that can silence or disable Anti-Mage for long periods of time will prevent him from Blinking away: Lion, 
Silencer, Shadow Shaman, 
Grimstroke, 
Witch Doctor, Riki, Faceless Void, 
Skywrath Mage, 
Puck.
Additional:
* Anti-Mage can use neither 
Blink nor Manta Style to escape from Smoke Cloud.
* Even if he activates a Black King Bar, his Manta Style illusions will still be blinded by Smoke Cloud.
* Riki has a very small mana pool and generally doesn't buy many items that increase it, making Mana Void ineffective.
Riki
* Heroes that can easily bypass Chen's creeps to get to Chen: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker.
Additional:
* Chen is basically Riki's natural prey: he has little HP, low armor and relies on his persuaded creeps to fight, which in most situations will not save Chen from Riki. Just be wary of {U:Centaur Conqueror}, who can stun Riki outside of Smoke Screen and ruin his attempt at Chen's life.
Dazzle
* Poison Touch severely slows down Chen, deals damage over time and weakens his armor every time he gets attacked by Dazzle or any of his allies. Aghanim's Shard upgraded Poison Touch can hex Chen and prevent him from saving his allies with 
Hand of God.
* Neither Chen nor his converted creeps have burst damage at all, so Dazzle will always have plenty of time to save his allies with Shallow Grave.
* Dazzle can use Shadow Wave can heal his allies, kill Chen's creeps and damage Chen himself.
* Bad Juju can weaken Chen's armor, and the armor of his creeps every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Riki
* Heroes that can easily bypass Io's allies to get to Io: Riki, Tusk, Clinkz, Sniper, Slark, Phantom Assassin, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, Spirit Breaker, 
Lifestealer.
Dazzle
* Poison Touch allows Dazzle to harass both, Io and it's tethered target on lane. Aghanim's Shard upgraded Poison Touch can also hex both, Io and it's tethered target, preventing them from escaping with Relocate, and also disarming them, silencing them, muting them and rendering them helpless against Dazzle and his allies.
* Io's damage output is one of the weakest, therefore Dazzle will have plenty of time to save an ally with Shallow Grave from gank by Io and it's tethered target.
* Shadow Wave will always hit both, Io and it's tethered target if they are near the ally Dazzle uses Shadow Wave on, while healing Dazzle's allies near them. Aghanim's Scepter upgraded Shadow Wave can bounce on both, Io and it's tethered target, causing them both to take damage and to be attacked by Dazzle. And unlike Io who doesn't get healed while using Tether, Shadow Wave will always heal Dazzle no matter on which of his allies he uses it on.
* Bad Juju will cause both, Io and it's tethered target to lose armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Additional:
* Poison Touch allows Dazzle to harass both, Io and it's 
Tethered target on lane. Aghanim's Shard upgraded Poison Touch can also hex both, Io and it's Tethered target, preventing them from escaping with Relocate, and also disarming them, silencing them, muting them and rendering them helpless against Dazzle and his allies.
* Io's damage output is one of the weakest, therefore Dazzle will have plenty of time to save an ally with Shallow Grave from gank by Io and it's Tethered target.
* Shadow Wave will always hit both, Io and it's Tethered target if they are near the ally Dazzle uses Shadow Wave on, while healing Dazzle's allies near them. Aghanim's Scepter upgraded Shadow Wave allows Dazzle Shadow Wave directly on Io and it's Tethered target which can also bounce on both, Io and it's tethered target, causing them both to take damage and to be attacked by Dazzle. And unlike Io who doesn't get healed while using Tether, Shadow Wave will always heal Dazzle no matter on which of his allies he uses it on.
* Bad Juju will cause both, Io and it's tethered target to lose armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Riki
* Riki: Smoke Screen can prevent Lone Druid from using True Form and Savage Roar, additionally it cause the spirit bear to miss on attacks which reduce the chances of getting rooted from it, with diffusal Blade, he can keep Lone Druid or the Spirit Bear inside the Smoke.
Dazzle
* Dazzle easily breaks the position of Lone Druid and his 
Summon Spirit Bear with his Poison Touch, As it always hits from afar and prolongs the slowdown on the Summon Spirit Bear, which is why he cannot catch up with Dazzle and treat his master with 
Spirit Link
* Dazzle helps his team survive the physical attacks of the Summon Spirit Bear thanks to the treatment from Shadow Wave and armor from Bad Juju, which can enable his team to kill Lone Druid
* The Lone Druid Summon Spirit Bear has a small amount of armor at the start of the game, because of Mid Dazzle, it can very much break through it and prevent Lone Druid from gaining an advantage at the very beginning of the game, giving his team the opportunity to overtake Lone Druid on items for killing him, by type: 
Spirit Vessel
Additional:
* Dazzle easily breaks the position of Lone Druid and his Summon Spirit Bear with his Poison Touch, As it always hits from afar and prolongs the slowdown on the Summon Spirit Bear, which is why he cannot catch up with Dazzle and treat his master with Spirit Link
* Dazzle helps his team survive the physical attacks of the Summon Spirit Bear thanks to the treatment from Shadow Wave and armor from Bad Juju, which can enable his team to kill Lone Druid

Riki
* Heroes with escaping and disjointing abilities can be good against Juggernaut:Anti-Mage Riki, 
Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
Dazzle
* 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.
Riki
* Heroes with high armor like 
Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and 
Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.
Additional:
* Smoke Cloud prevents the use of 
Death Pact, 
Searing Arrows and 
Skeleton Walk, so Clinkz can neither defend himself against Riki nor fight back effectively.
* It's hard to gank Riki as Clinkz has to find him first.
Dazzle
* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: 
Brewmaster, Dazzle, Tidehunter.
Riki
* 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.
Riki
* Heroes with abilities that can lock down Terrorblade and prevent him from using Sunder: Bane, 
Batrider, Earthshaker, 
Elder Titan, Faceless Void, Invoker, 
Legion Commander, 
Mars, 
Primal Beast, Riki, Shadow Shaman, Silencer, 
Vengeful Spirit, Void Spirit.
Dazzle
* Aghanim's Shard upgraded Poison Touch can be used to easily kill many of Terrorblade's illusions from both 
Conjure Image and Manta Style, it can also hex the real Terrorblade, silencing him, disarming him, slowing him, muting him and rendering him unable to do anything at all.
* Shallow Grave can be used to save an ally whom Terrorblade has used 
Sunder on under the condition Dazzle is quick enough to do it. And since Terrorblade has no "real" burst damage potential outside from Sunder, Dazzle will usually have plenty of time to save an allied hero on which Sunder was used.
* Shadow Wave will always damage Terrorblade and his illusions whenever Terrorblade has no 
Metamorphosis available to use, while healing Dazzle's allies. Aghanim's Scepter upgraded Shadow Wave can also be used directly on Terrorblade, and bounce on both Terrorblade and his illusions alike, causing them to take damage and to be attacked by Dazzle. Shadow Wave can also pierce throught debuff immunity by Black King Bar, one of the items Terrorblade relies on to survive in teamfights.
* Bad Juju can weaken Terrorblade's armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Additional:
* Aghanim's Shard upgraded Poison Touch can be used to easily kill many of Terrorblade's illusions from both Conjure Image and Manta Style, it can also hex the real Terrorblade, silencing him, disarming him, slowing him, muting him and rendering him unable to do anything at all.

Aghanim's Scepter upgraded Shadow Wave can also be used directly on Terrorblade, and bounce on both Terrorblade and his illusions alike, causing them to take damage and to be attacked by Dazzle. Shadow Wave can also pierce throught debuff immunity by Black King Bar, one of the items Terrorblade relies on to survive in teamfights.
* Bad Juju can weaken Terrorblade's armor every time Dazzle casts a spell while strengthening armor of Dazzle's allies.
Dazzle
* Venomancer's damage-over-time abilities are easier to heal through with numerous Shadow Waves than other types of damage, and it's simple to time a Shallow Grave until the last possible second to save a teammate from them.
Riki
* Riki usually buys Diffusal Blade to initiate, which renders Enchantress' movement speed useless, and is usually followed with Smoke Screen.
* Riki can effectively hit Enchantress by Tricks of the Trade alongside with Diffusal Blade and Smoke Screen's initiation. For a hero like Enchantress, 3 to 4 hits from Riki is a big deal, unless Enchantress built 
Force Staff earlier.
Riki
* Heroes who rely on their target to run away: Riki, Bounty Hunter.
Riki
* Blink Strike gives bonus backstab damage and can bypass Bulwark. Defensively, it could be used to teleport away from Mars, especially while inside Arena of Blood.
* Smoke Screen can interrupt Mars' skill combos, especially when cast inside Arena of Blood.
* Tricks of the Trade can be used to evade Mars' skills, which have a slight delay to them. It could also be used to buy himself time while trapped inside of Arena of Blood.
Additional:
* 
Bulwark is generally irrelevant against Riki as he primarily deals bonus damage from behind.
Dazzle
* Heroes that can save their allies can be a big problem for Mars: Dazzle, 
Omniknight.
Riki
* Sniper has no natural escape and relies on his range and slows to keep himself safe, which Riki can bypass with Blink Strike and quickly deplete his miniature HP pool.
Riki
* Riki has high damage and invisibility, meaning he can easily gank Rubick and kill him before Rubick has the chance to react.
* Cloak and Dagger renders Riki invisible, which makes his spells hard to steal if not being initiated.
* Similar to Clinkz, Rubick has to buy a large amount of Sentry Wards to keep track of Riki due to Cloak and Dagger, preventing Rubick from getting better items.
Riki
* Smoke Cloud prevents Storm Spirit from using any of his offensive and defensive spells, rendering him unable to effectively react to Riki's attack.
Additional:
* Smoke Screen prevents Storm Spirit from using his abilities once inside the radius. Riki can utilize this ability to allow his team to fight around Smoke Screen so that Storm Spirit cannot spam his spells to proc 
Overload.
Dazzle
* 
Reaper's Scythe is very predictable and gives Dazzle plenty of time to react with Shallow Grave: Dazzle just has to keep a close eye on his allies below 50% health.
* However, Dazzle must be sure to use Shadow Wave on that ally immediately after, or they will die from 
Heartstopper Aura when the Shallow Grave ends!
Additional:
* Dazzle's Shadow Wave is a spammable healing ability that spreads around his entire team, slowing the death of his teammates as effectively as Necrophos spreads damage to them.
* If not immediately, Shallow Grave delays his ally from gradually dying to Necrophos's abilities, especially Reaper's Scythe.
* However, bear in mind that Dazzle's Poison Touch, Shadow Wave and Bad Juju all deal physical damage, and Dazzle has no abilities to help him deal magical damage at all, which can cause problems for Dazzle to kill Necrophos if he uses Ghost Shroud to protect himself.
Riki
* Smoke Cloud prevents Queen of Pain from using any of her offensive and defensive spells, rendering her unable to effectively react to Riki's attack.
* It's easy to dodge 
Sonic Wave by using Blink Strike & Tricks of the Trade.
Riki
* 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.
Riki
* Without Dust of Appearance or Sentry Wards, Riki is able to silence Witch Doctor with Smoke Screen, and is likely to build a Diffusal Blade, leaving Witch Doctor without mana to cast Voodoo Restoration, as well as Skull Basher to interrupt Death Ward.
Riki
* Smoke Screen prevents Dark Willow from using her abilities, rendering her defenseless and unable to deal any serious damage.
* Blink Strike lets Riki jump past Bramble Maze.
Riki
* Smoke Cloud prevents 
Shukuchi and 
Time Lapse, leaving Weaver helpless against Riki.
* 
The Swarm is ineffective against Riki because invisibility instantly removes the beetles.
Riki
* Due to his low health and armor, Riki can easily kill Skywrath Mage.
* Smoke Screen prevents Skywrath from using all of his abilities, as he does not tend to buy Black King Bar.
* However, Skywrath Mage can easily kill Riki if he manages to root Riki with Rod of Atos or Gleipnir, followed by Dust of Appearance, Ancient Seal and Mystic Flare.
Riki
* Riki can potentially catch an Enigma out of position and prevent him from properly blinking and initiating, thanks to Cloak and Dagger.
* Before Enigma gets his Black King Bar, Smoke Screen can be used to cancel Black Hole. After Enigma gets Black King Bar, Riki can also cancel Black Hole with Abyssal Blade, which is a common item built on him.
* Tricks of the Trade renders Riki hidden and invulnerable, which in combination with Abyssal Blade allows Riki to cancel Black Hole with little to no worries of getting caught in it.
* Enigma's fragility during all stages of the game makes him extremely prone to Riki's ganking.
Riki
* Lifestealer cannot use 
Rage, 
Infest or 
Open Wounds when affected by Smoke Cloud's silence, and 
Feast cannot heal him effectively because of the blind, leaving him very weak both offensively and defensively.
* Infest ganks are harder when the enemy team has a Riki, as there are often only four heroes on the map that you can initiate on.
Riki
* Cloak and Dagger makes Sven unable to detect where Riki is until he shows or his team provides detection.
* Smoke Screen will make Sven miss attacks before he has his Black King Bar.
Riki
* Riki is known for being a successful support killer, something Shadow Shaman is very vulnerable to.
* Smoke Screen is particularly devastating to Shadow Shaman. With neither his various disables nor a solid health pool Shadow Shaman is usually dead. This forces Shadow Shaman to buy a Force Staff if he finds himself in this scenario and buy 
Sentry Wards if you have the money.
Riki
* Riki is a natural Diffusal Blade carrier, and it doesn't help that he's easily capable of sneaking up on Wraith King due to Cloak and Dagger.
* Riki can use Smoke Screen on top of Wraith King as he is reincarnating, making him a sitting duck for his second life. In addition, the blind prevents Wraith King from landing critical hits from Mortal Strike.
* Wraithfire Blast is quite predictable, and if Riki can react fast, he will disjoint it with Tricks of the Trade. There is also a chance he will become invisible again as the projectile travels, disjointing it.
Riki
* With Smoke Screen, Riki will silence and catch Medusa in a surprise with high miss chance flushing her from positions easily in team fights.
* He can deal a huge amount of damage through Cloak and Dagger, even through Mana Shield.
Riki
* Riki can detect early Roshan attempts because of Cloak and Dagger if he frequently checks the Pit.
* Ursa cannot 
Enrage when in Smoke Screen (Black King Bar will help though).
* Even if Ursa gets vision over him, Riki can Blink Strike away or use Tricks of the Trade after Ursa's initiation to avoid all 
Fury Swipes damage until 
Earthshock's slow is gone.
Additional:
* Riki can detect early Roshan attempts because of Cloak and Dagger if he frequently checks the Pit.
* Ursa cannot Enrage when caught in Smoke Screen and will miss his attacks (although Black King Bar will help with this issue).
* Even if Ursa gets vision over him and initiates with Earthshock, Riki can Blink Strike away or use Tricks of the Trade after Ursa's initiation to avoid Fury Swipes' damage until Earthshock's slow is gone.
Riki
* Smoke Screen combined with Diffusal Blade leaves Arc Warden effectively useless for a while as he struggles to escape the silence with low mobility.
* With Arc Warden's low mobility, Tricks of the Trade often deal decent damage to him before he moves out of it.
Riki
* Heroes that have superior mobility that can easily catch up with Mirana even after she used Leap to escape: Anti-Mage, Queen of Pain, Storm Spirit, Riki.
Riki
* Because Templar Assassin does not have escape potential in lane, any support hero with roaming potential and a Dust of Appearance can be great at shutting her down early game: Earth Spirit, Spirit Breaker, Tusk, Bounty Hunter, Riki, 
Warlock.
Riki
* Heroes with invisibility: (Riki, Clinkz, Nyx Assassin.
Riki
* Riki and Disruptor: Smoke Screen and 
Static Storm, respectively, can be thrown wherever Puck used Phase Shift, making Puck an easy target if it doesn't have Blink Dagger or is on cooldown. Puck is also very susceptible to Riki's high attack damage when attacking from the back. Glimpse also prevents Puck from escaping altogether.
Dazzle
* Once he buys Aghanim's Shard, Dazzle's Poison Touch can hex enemies, and hex can instantly kill illusions, making Dazzle strong against heroes who rely on illusions. Bear in mind that 
Chaos Knight is the exception because his 
Phantasms are strong illusions that are immune to abilities that can instantly kill illusions.
Dazzle
* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, 
Bristleback, Vengeful Spirit.
Riki
* Heroes with silences: Puck, Doom, Riki.
Riki
* Heroes that can gank Shadow Fiend in the early game: Earth Spirit, Nyx Assassin, Riki, Spirit Breaker.
Dazzle
* 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.
Riki
* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.
Riki
* Riki with Tricks of the Trade
* Heroes that can dodge Glimpse:
* Puck with 
Phase Shift
* Riki with Tricks of the Trade
* 
Phantom Lancer with Doppelganger
* Ember Spirit with 
Sleight of Fist and 
Activate Fire Remnant
* Chaos Knight with Phantasm
* 
Naga Siren with Mirror Image
* Tusk with 
Snowball
* Juggernaut with 
Omnislash
* Brewmaster with 
Primal Split
* Lifestealer with Infest
* 
Phoenix with 
Supernova
Riki
* Riki is another good hero to shutdown Death Prophet with Diffusal Blade as his core item. His Smoke Screen stops her from initiating and casting spells.
Riki
* Earthshaker must be careful not to use Blink Dagger or Aghanim's Scepter upgraded 
Enchant Totem to blink into Riki's Smoke Screen or 
Night Stalker's 
Crippling Fear, as these field effects will instantly silence Earthshaker and prevent him from initiating.
Riki
* Warlock is a very strong hero when positioned correctly, and his long cast range helps him with this. However, some heroes might disrupt or sneakily pass through his allies and deal with him, preventing him from doing his job. Such heroes include Chaos Knight, Spirit Breaker, Riki, and more.
Riki
* Another great threat to Riki since her 
Duel forces him to fight from the front and expose him for the entire duration, almost always guaranteeing an easy win (unless Riki has allies helping him).
* 
Moment of Courage can become hard to deal with as it doesn't cease with silence.
Riki
* Heroes with abilities that blind or cause Legion Commander to miss will prevent her from winning Duels: 
Arc Warden, Keeper of the Light, Riki, Tinker
Dazzle
* Shallow Grave prevents Legion Commander from killing her opponents in Duels.
* Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.
Riki
* Frail heroes who lacks mobility: 
Crystal Maiden, Enigma, Dark Willow, Vengeful Spirit.
Dazzle
* Heroes with armor reducing abilities greatly hinder Visage's defense like 
Slardar and Dazzle.
Riki
* Frostbite will reveal invisible heroes for its duration, making it a good tool against any such hero (Riki, Bounty Hunter, Weaver, or Clinkz for example), or as a soft counter to 
Shadow Blade, if it is used first. This can be an amazing tool to ensure that Dust of Appearance is used on the unit in question, and not wasted in not catching anything.
Riki
* Smoke Screen effectively disables Crystal Maiden's channeling spell: 
Freezing Field.
* Due to her low health and armor throughout the game, Riki can kill her easily.
Riki
* Heroes who rely on invisibility, such as Bounty Hunter, Clinkz, Mirana, Nyx Assassin and Riki, as they will be revealed if caught by Chronosphere.
Dazzle
* Shallow Grave can prevent the death of an ally that is trapped inside the Chronosphere.
* Shadow Wave lets Dazzle heal allies and damage enemies from outside Chronosphere.
Dazzle
* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Dazzle
* Aghanim's Shard upgraded Poison Touch can be used to hex Clockwerk, silencing him, disarming him, slowing him, and muting him, and thus rendering him unable to use 
Blade Mail to return damage or to do anything at all.
* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's very low damage output, Dazzle will have more than enough time to Shallow Grave any enemy hero Clockwerk initiates on.
Additional:
* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside 
Power Cogs.
* Due to Clockwerk's steady damage output, Dazzle has plenty of time to Shallow Grave anyone Clockwerk initiates on.
Riki
* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, 
Enchantress, 
Gyrocopter, Lion, Riki, 
Techies, 
Terrorblade, 
Necrophos, Invoker.
Dazzle
* Shadow Wave provides good sustain against Tinker's spammable abilities.
* Shallow Grave can stop Tinker from bursting down a target.
Riki
* In general, heroes who are melee with no way to fight back can be very easily poked by Monkey King to gain his Jingu Mastery stacks: 
Dark Seer, Riki, Rubick.
Riki
* Heroes with blind of some sort can be a bad choice for Monkey King to go on: 
Broodmother, Riki, Keeper of the Light.
Dazzle
* Some heroes with extreme range, like Zeus, Invoker or Clockwerk, can snipe your allies from anywhere after your Grave has expired.
Riki
* Heroes with silence: 
Death Prophet, Riki, Drow Ranger.
Riki
* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, 
Monkey King, Morphling, 
Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, 
Sand King, Spirit Breaker, 
Timbersaw, Tusk.
Dazzle
* Heroes that can deny Slark early kills will prevent him from snowballing: Dazzle, 
Abaddon.
Riki
* Charge of Darkness provides shared vision over its target, keeping track of heroes who rely on invisibility, mobility, or illusions: Riki, Broodmother, Phantom Lancer
Dazzle
* Heroes that can slow Charge of Darkness by a huge amount: 
Venomancer, Viper, Dazzle, Arc Warden, Lion, 
Huskar, Shadow Shaman, Visage, 
Undying, 
Jakiro.
Dazzle
* Shallow Grave prevents Ice Blast's shatter for up to 5 seconds, but can mostly only delay it as Ice Blast's debuff lasts 10 seconds and prevents Shadow Wave from healing them.
Additional:
* 
Ice Blast negates healing from Shadow Wave, and lasts longer than Shallow Grave.
Riki
* Riki can get on top of Ancient Apparition very easily with Blink Strike. This can also double as a way to dodge Ice Blast, along with Tricks of the Trade.
* Ancient Apparition will frequently resort to casting Ice Blast right before dying. Smoke Screen can be used to prevent this, stopping Ancient Apparition from having any impact.
Riki
* 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.
Dazzle
* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, Dazzle from Aghanim's Shard with upgraded Poison Touch.
Riki
* Axe can disable
Cloak and Dagger's invisibility with 
Berserker's Call, which forces Riki to attack him at a very bad angle.
Counter Helix ignores Riki's armor and goes straight for his tiny HP pool, totally ignoring 
Smoke Screen.
* Axe has a very high HP pool, making it hard for you to kill him before you get big items - that is if you survive engaging him.
* Axe is a natural buyer of Blade Mail and Riki generally does not buy lifesteal items, causing Riki to kill himself when attacking due to your tiny HP pool.
Dazzle
* Culling Blade ignores the protection from
Shallow Grave and will kill any target whose health is low enough. This makes Axe one of the hardest counters to Dazzle, and he neutralizes one of Dazzle's most important abilities.
Culling Blade kills any target under the health threshold, even through Shallow Grave.
