Lion
* Heroes who have most or all their abilities (damage or disable) unable to pierce spell immunity: 
Keeper of the Light, 
Lina, 
Lion, 
Zeus.
Additional:
* 
Rage makes Lifestealer debuff immune and gives him magic resistance which can drastically reduce magical damage from Lion's abilities while also preventing Lion to do anything to him.
* Lion's lack of inner escape and defensive mechanisms increases 
Ghoul Frenzy effectiveness, since it applies slows upon attacking.
* Lifestealer's physical damage output is strong against Lion's low health and base armor
* 
Infest can be used to surprise unsuspecting Lion if he tries to take down alone enemy hero. 
Aghanim's Scepter upgraded Infest can be used to disarm Lion and attack him from inside, even if Lion is debuff immune with the 
Aghanim's Shard upgraded 
Mana Drain.
Sniper
* Lifestealer can close the distance to Sniper by using Infest on a fast or durable creep to tank Sniper's damage.
* 
Open Wounds and Ghoul Frenzy will reduce Sniper's mobility heavily, and Rage's movement speed bonus helps in closing the gap to Sniper. It also protects him from Assassinate and Shrapnel.
* Infest can dodge an incoming Assassinate or to surprise Sniper during ganks. Aghanim's Scepter upgraded Infest can also allow Lifestealer to disarm Sniper and attack him from inside.
Lion
* Lion has an incredibly fragile health pool, making him weak against nukers like 
Tinker or 
Oracle.
Sniper
* Tinker is one of the few heroes who is able to defeat a Sniper on the center line thanks to his long-ranged abilities.
* 
Laser allow Tinker to deal damage to Sniper and blind him, causing him to miss attacks more often.
* 
Heat-Seeking Missile can deal heavy damage to Sniper on lane.
* 
Defense Matrix allow Tinker to save himself or allies from 
Assassinate.
* 
Warp Flare from Aghanim's Shard allows Tinker to teleport Sniper away from himself, while also reducing both his attack range and cast range. If Sniper is teleported near Tinker's allies with Warp Flare, he will be bursted down in no time.
Additional:
* Tinker is one of the few characters in Dota 2 who is able to defeat a Sniper on the center line – Tinker. On the center line, he gains an advantage over his opponent, and later acquires additional control. It is these abilities that the enemy should have in the game against the Sniper.
Lion
* A well-timed 
Counterspell reflects all targeted abilities back at Lion, potentially stunning or hexing him or even making himself burst down.
Sniper
* Anti-Mage can close the gap with 
Blink. Sniper will struggle to escape once he is jumped on due to the lack of mobility.
* Counterspell reduces sniper's magic damage from 
Shrapnel and Assassinate. The active component can also reflect the projectile back to sniper if he dares to target Anti-Mage. This is seriously detrimental for Sniper as he is prone to buying 
Khanda to boost effects of the Assassinate.
* Sniper often relies on mana to use items for escaping, and his abilities cost a lot of mana. 
Mana Break drains Sniper's mana and takes away Sniper's means to disengage.
* Anti-Mage has faster farming speed. He can outfarm and get ahead of Sniper easily.
Lion
* 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.
Lion
* 
Waning Rift silences and damages enemies affected by the ability, diminishing Lion's punishing powers.
* High burst damage potential plus mobility and disable through 
Illusory Orb, Waning Rift, and 
Dream Coil allows Puck to effortlessly chase, lock and/or kill Lion, as the Demon Witch lacks proper ways to avoid so.
* 
Phase Shift allows Puck to dodge 
Earth Spike, 
Finger of Death and breaks Mana Drain's link.
Sniper
* Sniper has no spells to disable Puck. He lacks a silence to prevent spell casting and a stun to disable, allowing Puck to act instantly against Sniper.
* Sniper's main strategy is to attack his enemies from a safe distance. Illusory Orb, combined with Blink Dagger makes it easy for Puck to get close to Sniper. Due to his low health, he is also easily nuked down by Puck.
* The status debuff placed by Assassinate on its target makes it very easy to avoid it. Puck has 2 (3 when having 
Blink Dagger, 4 when having 
Eul's Scepter of Divinity, 5 when having 
Linken's Sphere) methods to disjoint or dodge the projectile, making it a bad spell for finishing off Puck.
Lion
* Backline supports (Lion,
Crystal Maiden) can keep Puck pinned long enough for a kill.
Lion
* Lion's lack of escapes gives 
Slark easier time to catch him through 
Pounce.
* 
Shadow Dance gives Slark the advantage of being untargetable, nullifying single target abilities (such as non-upgraded 
Hex, Mana Drain and Finger of Death).
* 
Dark Pact applies multiple instances of strong dispel on Slark, which is strong against any of Lion's disables.
* Lion's low health pool and low armor make him extremely vulnerable to Slark's damage output.
Sniper
* Sniper hugely lacks mobility and escape abilities so that he is an easy target for ganks from Slark.
Lion
* Heroes with heavy magical nukes will take advantage of Slark's poor HP or force him to use Shadow Dance early: Lina, Lion, Zeus
Lion
* Batrider often hides in the trees to initiate on a target. As such, he has a slight edge against heroes that have no scouting tools and cannot see him coming, such as Lion or 
Sven.
Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: 
Batrider, 
Disruptor, 
Pudge, 
Vengeful Spirit.
Sniper
* Clockwerk is also the least optimal target for Sniper to attack in a teamfight, although more experienced players will rarely make this mistake.
* With no mobility or disable skills, getting trapped in Power Cogs is a death sentence for Sniper.
Sniper
* Sniper is completely helpless against Broodmother's abilities, and can be seriously damaged by Spiderlings in lane, especially when Shrapnel is on cooldown.
Sniper
* Invoker's arsenal of magical spells are troublesome for Sniper who has low HP and high armor, which does not benefit him much against Invoker.
* Besides magical damage, he can be disarmed and repeatedly mini-stunned with 
Cold Snap, preventing him from reacting.
* Leveling 
Quas can allow Invoker to lane effectively against Sniper despite right-click harassment.
Lion
* 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.
Sniper
* Sniper's low mobility and lack of defensive abilities make him an easy gank target for the entire game, especially if Blink Dagger is picked up.
Lion
* Heroes with long or multiple disables will prevent Legion Commander from winning Duels: Shadow Shaman, Lion
Sniper
* Slardar can use 
Guardian Sprint with Blink Dagger or 
Shadow Blade to get close, and 
Slithereen Crush will stun Sniper and slow him, making him vulnerable to Slardar's teammates.
* 
Corrosive Haze lowers Sniper's armor and makes Sniper's Shadow Blade useless, easily killing him with a few attacks.
Sniper
* Assassinate is easy to reflect with Spiked Carapace for massive damage.
* Shrapnel's area damage can set up an easy stun with Spiked Carapace, especially when combined with Vendetta.
* In the early game, Sniper's low health pool and high intelligence makes him easy prey for Nyx Assassin.
Sniper
* Sniper's lack of mobility and escape mechanisms makes him one of the easier heroes for Bloodseeker to gank.
Sniper
* 
Headshot and Shrapnel slow is ineffective against a team with haste (which Stampede gives).
* Commonly picked up mobility items and hasted movement during his Stampede (as well as his high health pool) make him extremely hard to kill from a distance, damaging 
Sniper with Retaliate and 
Blade Mail if he has one.
* A low health pool and no escape mechanism makes him an easy target for Centaur Warrunner's burst damage and initiation (even making his team possible initiators with Stampede).
Sniper
* Sniper has a low health pool and strength gain, making him vulnerable to Pudge's magical and pure damage.
* Sniper usually likes to deal damage away from the fight, and Meat Hook is capable of bringing him to the front lines.
* Assassinate won't do much damage against Pudge because of his high strength gain and the strength bonuses from Flesh Heap.
* Shrapnel will be mostly blocked by Flesh Heap's active.
Additional:
* Pudge's 
Meat Hook allows him to bring Sniper in the middle of any fight, and the pure damage does well against his high armor and low health.
* 
Dismember can lock Sniper down, which makes him highly vulnerable and gives enough time for Pudge to kill him alone. Aghanim's Shard upgraded Dismember will also allow Pudge to save an ally from Assassinate.
Sniper
* 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.
Sniper
* Magnetic Field's evasion completely negates Sniper's attacks unless he has True Strike.
* Sniper always positions himself far away from battles, which makes him especially vulnerable for Flux and Spark Wraith.
Sniper
* Sniper is very fragile and has low movement speed, making an exceptionally easy target for Chaos Knight to initiate on.
* Sniper has no innate ability to deal with 
Phantasm or escape a 
Reality Rift and 
Chaos Bolt combo.
* In most cases, Sniper likes to stay far in the backline to deal damage, thus he is vulnerable if Chaos Knight manages to jump on him in the back line, which will usually spell a quick end for Sniper.
Sniper
* 
Snowball allows Tusk to move himself and allies towards Sniper whilst invulnerable and hidden.
* His 
Ice Shards may also block pathing for Sniper as he has no means of moving through obstacles. In addition, 
Tag Team can hinder Sniper's escape.
Additional:
* Tusk alone or with his teammates can close Sniper's long range easily with Snowball, even wasting Shrapnel, ending with a very vulnerable Sniper.
* Walrus PUNCH!'s very high physical damage output can easily kill Sniper instantly due to his low health and armor.
Sniper
* Sniper's 
Take Aim can be wasted with either Muerta's 
Pierce the Veil or a well aimed 
Dead Shot.
* Dead Shot can displace Sniper from safe spots into the offensive range of Muerta's team, leading to potential kills on Sniper.
* Sniper relies heavily on his basic attacks, which is useless against Pierce the Veil.
Sniper
* Even if he can slow Mars down with Shrapnel and Headshot, Mars can tank Sniper's physical damage simply by facing him with Bulwark, allowing him to endure his auto-attacks into the late-game. Should Sniper choose to attack someone else, Mars can redirect his projectiles with Bulwark's active ability.
* Sniper's poor mobility makes him very vulnerable to Arena of Blood, especially in the early game. Mars can also take advantage of this by pushing him closer to the front line with Spear of Mars.
Lion
* Hex and Earth Spike do not cancel 
Sharpshooter, making those two abilities ineffective against her.
* Although Hoodwink should be wary of his Finger of death, as it can possibly kill her.
Sniper
* Lina defeats Sniper on the mid, because she has the same attack range as him, and her 
Dragon Slave ability deals much more damage to creeps, as well as to Sniper himself, than Shrapnel, which creates uncomfortable conditions for Sniper to farm on the line, which is why Lina either punches Sniper harder than he either pushes a pack of creeps up to the tower and finishes off his creeps under it, preventing Sniper from earning gold and a level.
Additional:
* Lina defeats Sniper on the mid, because she has the same attack range as him, and her Dragon Slave ability deals much more damage to creeps, as well as to Sniper himself, than Shrapnel, which creates uncomfortable conditions for Sniper to farm on the line, which is why Lina either punches Sniper harder than he either pushes a pack of creeps up to the tower and finishes off his creeps under it, preventing Sniper from earning gold and a level.
Lion
* 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.
Sniper
* Fortune's End can catch out or impair position-based heroes with low mobility, such as Sniper or 
Razor.
Lion
* Heroes with long disables, like Lion, 
Night Stalker, or Legion Commander, can prevent Oracle from using spells or items.
Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit.
Lion
* Both Lion's Finger of Death and Lina's 
Laguna Blade have a 0.25 second delay before the damage is dealt.
Additional:
* 
Aphotic Shield applies strong dispel on targeted allies, while 
Borrowed Time does the same on 
Abaddon himself upon both casts (manually or automatically), removing disables, such as Earth Spike and Hex.
* Abaddon may offer survivability to Lion's nuke power by shielding and healing allies and himself.
* Lack of inner escape and defensive mechanisms increases 
Curse of Avernus effectiveness, since it slows per stack (applied upon auto attacking), and silences when it reaches the maximum stack.
Lion
* Just like 
Rubick, the Disruptor may effortlessly put Lion in life threatning danger and render him helpless by manipulating his position with 
Glimpse.
* Disruptor's longer cast range and lingering disable makes Lion struggle to defend himself, possibly being affected by Disruptor's abilities without even seeing the thrall.
Sniper
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: Batrider, Disruptor, Pudge, Vengeful Spirit.
Sniper
* Sniper can kill Disruptor while he is trapped by Kinetic Field from a long range.
* Sniper generally stays in the back, making it hard for Disruptor to cast any of his skills on him in lane.
Sniper
* Heroes with high mobility can approach Sniper: 
Anti-Mage, 
Earth Spirit, 
Io, 
Nature's Prophet, 
Pangolier, Puck, 
Queen of Pain and most notably Riki.
Sniper
* You can easily kill a squishy Sniper, due to your high movement speed and his lack of escape.
Lion
* Heroes with low health: 
Lich, Crystal Maiden, Lion.
Lion
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like 
Mirana's 
Sacred Arrow or 
Leshrac's 
Split Earth, or combos like 
Kunkka's 
X Marks the Spot into 
Torrent.
Lion
* 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.
Sniper
* 
Clinkz, Sniper, 
Lone Druid, 
Troll Warlord, Legion Commander and 
Wraith King are some of the Heroes that base themselves on attacks with little or no spell power, so they suffer in the grassy hands of Overgrowth.
Sniper
* Sand King is a strong ganker, allowing him to shut down squishy heroes in the early game: 
Phantom Assassin, Clinkz, Sniper, 
Enchantress.
Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Heroes who have high health are a problem for Sniper because he likes to attack the closest target and sit at the back, much like a 
Terrorblade so when that hero doesn't die; he's forced to show his position for a very long time: 
Centaur Warrunner, Legion Commander, 
Primal Beast.
Lion
* 
Tidehunter is a core builder of 
Pipe of Insight. Along with natural high health pool, it's tough to burst the Leviathan down.
* 
Kraken Shell thwarts long disables attempts if Tidehunter receives enough damage.
* 
Gush and 
Ravage long cast and reach ranges will effortlessly hit Lion, either bursting him down or making him extremely vulnerable and worn in matter of seconds.
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, 
Doom, Tidehunter, 
Underlord, Troll Warlord, and etc.
Sniper
* Sniper relies on distance. Bounty Hunter can use Shadow Walk to get close, and Jinada can do massive damage and slow down Sniper in the early game.
* Track gives additional speed to Bounty Hunter and makes Shadow Blade useless, which can allow Bounty Hunter to easily kill him with a few attacks.
Lion
* Finger of Death can instantly shred many targets, especially fragile Heroes like Keeper of the Light, 
Ancient Apparition or 
Bounty Hunter.
Sniper
* Being mostly a physical damage dealer, Sniper's effectiveness is greatly reduced by Omniknight's 
Guardian Angel.
* Omniknight's 
Degen Aura allows him to slow sniper and catch him. Sniper has to then use some escape item.
* Omniknight can also protect an ally from being finished off by Assassinate by using 
Purification and 
Repel which grants a massive strength boost.
Lion
* Heroes who can drain mana can make Omniknight useless after he uses one or two abilities: Lion, Anti-Mage, 
Nyx Assassin.
Sniper
* Spirit Breaker can charge towards Sniper from anywhere on the map with 
Charge of Darkness.
* 
Greater Bash deals magical damage, which can prove dangerous to Sniper and his low health.
* Both previous abilities combined with 
Nether Strike ensures that Spirit Breaker can easily solo kill Sniper.
Lion
* 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.
Lion
* Mana Drain can be easily canceled with Ice Path. However, Lion can counter this by buying his Aghanim's Shard though, that is no longer possible, but Jakiro can counter this too with Aghanim's Scepter upgraded 
Macropyre will deal pure damage through the debuff immunity forcing Lion to cancel it or die.
* Lion has very strong single target capabilities, but usually struggles against multiple heroes, while Jakiro has good multi-target capabilities, His abilities also have a much shorter cast range then Jakiro's, allowing Jakiro to cast his abilities before he can get off his Hex or Earth Spike.
* Jakiro can also save an ally who Lion is attempting to Finger of Death by casting 
Ice Path on Lion.
Sniper
* Heroes with good counter-push abilities to clear creep waves can hinder Jakiro's early pushing ability: 
Death Prophet, Sniper, Tinker, 
Windranger.
Sniper
* Storm Spirit can close the distance towards Sniper very easily with his ultimate 
Ball Lightning.
Additional:
* Sniper is very squishy and cannot deal with heroes that jump onto him and lock him down. Storm Spirit closes the gap in a fight against Sniper, and Sniper has no way to escape except for some items.
* Storm Spirit can dodge Assassinate with a correctly timed Ball Lightning.
Lion
* Heroes with mana burn: Nyx Assassin, 
Invoker, 
Outworld Destroyer, 
Pugna, Lion
Sniper
* 
Viper Strike breaks Sniper's passives.
* 
Corrosive Skin allows Viper to deal more damage to Sniper than Sniper deals to him when laning, especially by briefly stepping into Shrapnel.
* 
Nethertoxin together with 
Poison Attack can slow Sniper and tears through his low health and mobility.
Lion
* Heroes that can drain mana negatively affect Viper's ability to use Poison Attack, Nethertoxin and Viper Strike: Lion, Anti-Mage
Sniper
* Pangolier can easily get close to Sniper with Swashbuckle and Rolling Thunder, negating Sniper's range advantage.
* Lucky Shot disarms Sniper and leaves him unable to effectively fight back.
Sniper
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, 
Templar Assassin, 
Arc Warden
Sniper
* 
Ensnare with her attacks allows Naga Siren to gank Sniper easily.
* Rip Tide removes Sniper's very little armor.
Lion
* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like 
Phantom Lancer, 
Naga Siren and Terrorblade, who rely on illusion armies.
Additional:
* Both Hex and Mana Drain destroy Naga Siren's illusions in an instant, making it hard for her to teamfight or push against a team with Lion. If Lion chooses the AoE effect talent for Hex or the shard for multi-target Mana Drain, it can negate her pushing potential entirely.
* Earth Spike is an AoE disable with good damage. If used well, it can help distinguish the true Naga Siren by the damage they take (illusions take more damage).
Lion
* 
Medusa lacks mobility or escape mechanisms. Earth Spike and Hex can neutralize her strong damage potential and allow for Lion's team to focus her down.
* Mana Drain is a perfect ability to weaken Medusa's durability as it can quickly drain her 
Mana Shield, making her far less tanky. Mana Drain can also be used to restore mana of Lion's allies, which can nullify the mana steal from 
Mystic Snake.
* Mana Drain, along with Hex, destroy illusions instantly, which may be extremely helpfull and efficient against core builders of 
Manta Style, like Medusa herself.
Sniper
* Sniper can outrange both Medusa's arrows and Stone Gaze, allowing him to focus her down during a teamfight.
Additional:
* Medusa is a fairly immobile hero that deals damage around her with 
Split Shot. Sniper should outrange her and should stay out of harm's way from Split Shot.
* More importantly, Sniper should have enough attack range to fire at Medusa during her 
Stone Gaze without turning to stone, so the ultimate is mostly wasted against him.
Lion
* Heroes with high burst damage: Lina, Lion, 
Luna, Nyx Assassin, Queen of Pain.
Sniper
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his Shadowrazes.
Additional:
* Shrapnel can be used to cancel Shadow Fiend's Blink Dagger from a huge range.
* Take Aim and Headshot allow Sniper to harass Shadow Fiend in lane without getting into the range of his 
Shadowraze.
* Assassinate when upgraded with Aghanim's Scepter can be used to cancel Shadow Fiend's 
Requiem of Souls.
Lion
* 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.
Sniper
* Heroes who outrange Drow Ranger such as Sniper, Tinker.
Lion
* Enigma is fragile, and lacks escapes, being dependent on Blink Dagger for mobility. Ganking Heroes or Heroes with burst damage will likely kill him before he can do anything. Such Heroes include: Lina, Lion, Luna, Puck, Slark, Nyx Assassin, etc.
Sniper
* Take Aim extends Sniper's attack range, allowing him to position himself safely behind his team, making it difficult to catch him in Enigma's relatively small area-of-effect for 
Black Hole. When left unattended, he can quickly kill a channeling Enigma (often from the high ground) to rout an otherwise strong initiation.
* In the early game, Sniper can cancel Enigma's Black Hole with Assassinate's ministun. Due to the absolutely ginormous 3000 cast range on Assassinate, Sniper does not need to be too close to Enigma to cancel his Black Hole. Aghanim's Scepter upgraded Assassinate can also stun Enigma for a longer duration.
* Both Shrapnel and Assassinate put Enigma's Blink Dagger on cooldown, potentially forcing him to prematurely activate 
Black King Bar.
Additional:
* Sniper has a very long range, so it is rare that Enigma can catch him in a Black Hole.
* Assassinate can easily cancel Black Hole if he is not caught, especially with Aghanim's Scepter.
* Enigma's Eidolons from 
Demonic Conversion are useless to push against a Sniper as he will easily kill them, especially with 
Mjollnir, a common item on Sniper.
Lion
* Heroes with high magical burst can easily kill Huskar when he is at low health: Lion, Lina, Skywrath Mage
Sniper
* Sniper just doesn't give Huskar a chance, as he always just keeps his opponents at a great distance. However, in such a game you will need to have a 
Concussive Grenade and a 
Hurricane Pike in order to avoid the 
Life Break of Huskar
Additional:
* Sniper just doesn't give Huskar a chance, as he always just keeps his opponents at a great distance. However, in such a game you will need to have a Concussive Grenade and a Hurricane Pike in order to avoid the Life Break of Huskar
Lion
* Wraith King has a very low mana pool and is extremely dependant on it to cast his high mana cost abilities, so Mana Drain will make him struggle way too hard, even not being able to active his passive ability 
Reincarnation, forcing the Wraith King to buy Aghanim's Shard as soon as possible.
* Althought Wraith King may not be as fragile to struggle against Lion's damage, it's much easier to disable and harass him, as Wraith King doesn't have any mobility at all, his only gap closer being 
Wraithfire Blast which costs too much mana for his mana pool, and may only affect one target.
Additional:
* While not being able to confront Wraith King by himself, Lion's Mana Drain helps in draining Wraith King's mana, preventing him from reincarnating unless he has his Aghanim's Shard.
* Lion's Earth Spike and Hex provide decent lockdown against Wraith King as well, preventing the latter from benefiting from Vampiric Spirit bonuses.
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Lion
* Heroes with channeling spells, for Chen has no disables on his own, hates buying disabling items and his creeps are often not fast enough to cancel them: 
Enigma's Black Hole, Witch Doctor's 
Death Ward, Shadow Shaman's 
Shackles, Lion's Mana Drain, 
Bane's 
Fiend's Grip, Pudge's Dismember, Crystal Maiden's 
Freezing Field, Pugna's 
Life Drain, 
Dawnbreaker's 
Solar Guardian, and Naga Siren's 
Reel In from Aghanim's Scepter.
Sniper
* 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.
Lion
* Long range disables are really effective against dangerous area controllers and channeling Heroes, like Enigma, Faceless Void or Crystal Maiden, as it may cancel them or prevent enemies from doing further damage while keeping Lion in a relatively safe distance in the warzone.
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Sniper
* Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
* Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
* Thanks to Shrapnel and Headshot, Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
Lion
* Hex greatly reduces Timbersaw's mobility.
* In addition, Lion can follow up with his Earth Spike and Mana Drain combo, preventing Timbersaw to escape with Timber Chain. And he can finish Timbersaw off with Finger of Death if the latter's HP is low enough.
Sniper
* His increased attack range makes it very hard to get close enough for Static Link, Eye of the Storm and Razor's own attacks.
* Headshot procs will slow Razor heavily regardless of Storm Surge, as it will knock him back for a brief duration.
Sniper
* Sniper can easily destroy 
Plague Ward from long range.
Sniper
* Sniper's position in the far back line makes him unlikely to be hit by any of Grimstroke's abilities during teamfights.
* Sniper is relatively unaffected by the silence from Phantom's Embrace.
* Sniper's long range and fast projectile speed allows him quickly to destroy any Phantoms attacking his allies.
Lion
* Lion's instant cast point shuts down his initiation and buys time for his allies to catch up.
* Void Spirit has to be cautious when fighting, as he has no protection against Finger of Death. If caught out in a stun, the high magic damage could end him quickly.
Lion
* Mana Drain depletes Necrophos's mana pool, preventing him from using his abilities.
* Finger of Death deals high magical damage, which becomes amplified by Ghost Shroud.
Lion
* Hex's instant cast time will force Brewmaster into the awkward situation of needing some form of spell immunity or block to prevent being immediately hex upon blinking in, or wait until Lion has used all his crowd control before entering a fight. His direct magic burst also makes Brewmaster's Drunken Brawler worthless versus Lion.
Sniper
* A Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to Take Aim.
* However, an illusion of Sniper made with Wall of Replica is extremely powerful, and hard to deal with.
Sniper
* Shrapnel can be used to disable Earthshaker's Blink Dagger from long range.
* Take Aim allows Sniper to harass Earthshaker in lane, and stay out of Echo Slam initiation radius.
Additional:
* Sniper is able to kite Earthshaker with his very long range.
* Sniper can dodge Earthshaker's stuns like 
Fissure and 
Enchant Totem with mobility items such as Blink Dagger, 
Force Staff/Hurricane Pike and Shadow Blade/
Silver Edge.
* Sharpnel can be used to cancel Earthshaker's Blink Dagger and preventing effective use of his 
Echo Slam in a majority of situations.
Sniper
* Sniper can easily destroy 
Tombstone from long range.
Sniper
* As Outworld Destroyer has short cast ranges, a short attack range, and no gap-closing abilities, Sniper can kite and harass Outworld Destroyer in lane with his long range and zone him out in fights. The continuous area damage from Shrapnel also prevents Astral-Blink escapes.
* However, in the late game, Outworld Destroyer's massive damage can overwhelm Sniper once he obtains Blink Dagger, Force Staff etc. to close the gap.
Sniper
* Sniper can easily destroy 
Mass Serpent Wards from long range.
Sniper
* Juggernaut deals most of his damage in the melee range and has no gap-closer. Sniper can easily harrass Juggernaut from afar with his long-ranged attacks and {Ability ID:Headshot|Sniper|16px} procs.Should Juggernaut decide to advance,Sniper has enough time to react and back off.
* Sniper's long range attack can destroy 
Healing Ward from a safe range, preventing any healing done to Juggernaut and/or his teammates.
* However, if Sniper is badly positioned, Juggernaut can easily terminate him.
Lion
* With a lot of disables with good range, he might cancel your Echo Stomp.
* Mana Drain can be used to drain Elder Titan's already low mana pool.
Lion
* If Meepo ganks Lion with Poof and Earthbind, he will be an easy target for Earth Spike & AoE Hex from his level 25 talent.
Lion
* 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.
Lion
* Squishy heroes, usually supports, like Lion, Ancient Apparition, Keeper of the Light etc can die quickly to Tiny's magic burst.
Lion
* 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.
Sniper
* Long ranged heroes like Sniper or Drow Ranger can kite Tiny effectively if he doesn't get the jump on them first.
Sniper
* Heroes that can maintain vision on Monkey King can see when he uses Tree Dance: 
Bloodseeker, 
Treant Protector with Eyes In The Forest, Sniper, 
Weaver
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Shrapnel and Headshot allows Sniper to kite Troll Warlord effectively.
* Take Aim together with certain items such as Hurricane Pike allow Sniper to sit and fire at Troll Warlord from a safe distance.
Lion
* Skywrath's pitiful defences also make him easy meat to heroes with high burst like 
Juggernaut, Lion, or Phantom Assassin, the latter occasionally downing a support Skywrath in a single 
Stifling Dagger.
Lion
* Finger of Death can instantly shred many targets, especially fragile Heroes like Keeper of the Light, Ancient Apparition or Bounty Hunter.
Sniper
* Heroes who have high health are a problem for Sniper because he likes to attack the closest target and sit at the back, much like a Terrorblade so when that hero doesn't die; he's forced to show his position for a very long time: Centaur Warrunner, Legion Commander, Primal Beast.
Additional:
* Sunder can save himself or his allies from Assassinate.
* Sniper relies on right-clicks to deal damage in the late game, and Terrorblade's high armor can reduce his damage significantly.
* Terrorblade is a far harder carry than Sniper is, so a well-farmed Terrorblade can easily defeat a Sniper.
Lion
* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.
Sniper
* Unlike with other heroes who can summon illusions of themselves, Terrorblade's illusions from 
Conjure Image have different colors than other illusions which can be seen even by enemy team, which can also make Terrorblade weak even against heroes he naturally counters: Bane, 
Lifestealer, 
Spectre, 
Chaos Knight, Spirit Breaker, Sniper. Terrorblade's only solution to counter this problem is to get Manta Style as quickly as possible.
Lion
* Lion's Mana Drain is a headache for Bristleback to deal with during the laning stage, as it denies him the ability to get last hits with Quill Spray.
Sniper
* Melee heroes who may struggle to get close to Sniper: Wraith King, Kunkka, Doom, Tidehunter, Underlord, Troll Warlord, and etc.
Additional:
* Sniper's very long range allows him to stay out of 
Firestorm, 
Pit of Malice as well as 
Atrophy Aura's range.
* Escapes with 
Fiend's Gate can be canceled with Assassinate that can mini-stun the target.
* However, Fiend's Gate can be used to quickly close the gap on Sniper, and kill him if Underlord brings his allies with him through Fiend's Gate. And Sniper has nothing to intercept arrivals with Fiend's Gate outside of Shrapnel and Concussive Grenade from Aghanim's Shard.
Sniper
* Frail heroes who lack mobility can also be an easy target to lock down with Chronosphere, such as Drow Ranger, Luna, Sniper, Terrorblade.
Lion
* Long range disables are really effective against dangerous area controllers and channeling Heroes, like Enigma, Faceless Void or Crystal Maiden, as it may cancel them or prevent enemies from doing further damage while keeping Lion in a relatively safe distance in the warzone.
Sniper
* Heroes that can easily kill Faceless Void from outside his Cronosphere; Sniper, Skywrath Mage, etc.
Lion
* Heroes that can kill Death Prophet with nukes can prevent her from using Exorcism to its full duration or using it at all: Lina, Lion, Puck, 
Morphling.
Lion
* Heroes with high magical burst damage will kill Gyrocopter before he gets to do much: Lina, Lion, Zeus
Sniper
* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna
Lion
* Due to her slow movement speed,heroes with crowd control and slows can shut down Dawnbreaker:Lion, Crystal Maiden ,
Venomancer etc.
Lion
* 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.)
Lion
* Heroes with silence and mana drain abilites, as Ancient Apparition relies entirely on his abilities: Invoker, Silencer, Nyx Assassin, Skywrath Mage, Shadow Shaman, Lion and etc.
Sniper
* Squishy core heroes (
Shadow Fiend, Sniper, etc)
Sniper
* Shrapnel can sometimes scout out Magnus and also place his Blink Dagger on cooldown. Aside from that, Sniper likes to stay far back behind enemy lines, so it's difficult to catch him with Reverse Polarity unless you already have vision on him and can Skewer him to the rest of his team.
Sniper
* 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.
Lion
* All of Lion's abilities are active making Demonic Purge break from Aghanim's Scepter useless.
* Hex and Mana Drain can make quick work of whatever illusions you're creating, especially when he acquires his Talents at level 20 and 25.
* An attempt to save an ally using Disruption can easily become a perfect setup for a Earth Spike or Finger of Death with Aghanim's Scepter for the enemy.
Lion
* Nether Ward will be problematic for heavy nukers and spammers like Skywrath Mage, Lina, Lion and Invoker, but Pugna must not use Decrepify defensively against them as he will be helping them out more than anything.
Sniper
* Sniper's huge range makes him an unviable target to use Life Drain on, forcing Pugna to risk playing out of position to use it on Sniper.
* Sniper's Shrapnel can be used to provide vision on Nether Ward, and his range allows him to easily take it out.
* A clumsy Pugna may accidentally boost Sniper's Shrapnel and Assassinate damages if he recklessly uses Decrepify on himself or his allies.
Lion
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like Mirana's Sacred Arrow or Leshrac's Split Earth, or combos like Kunkka's X Marks the Spot into Torrent.
Sniper
* With his Take Aim, Sniper can simply sit out of your ability range and deal massive damage if not killed first.
* Assassinate can target allies who are still alive with low health because of Ghostship's buff.
* Headshot makes it harder for Kunkka to position/escape and makes it hard for Kunkka to hit with Tidebringer.
Sniper
* Invisible heroes all have the element of surprise. Provided they deal enough damage, Sniper should be vanquished very quickly: Clinkz, Riki, Bounty Hunter.
Lion
* Hex and Earth Spike can hold Clinkz down, giving him no chance to use Black King Bar or Skeleton Walk.
* Finger of Death quickly kills Clinkz due to his low health.
Sniper
* Early game gankers can make life very difficult for a Sniper if he keeps being caught: 
Ursa, Pudge, Earth Spirit.
Lion
* Lion has two low cast point disables (Hex and Earth Spike) to control Ursa before he buys a Black King Bar.
* Hex is one of the few abilities that cannot be dispelled even with an Aghanim's Scepter upgraded Enrage.
* Lion can control Ursa's low mana pool via Mana Drain.
Lion
* 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.
Sniper
* Due to Sniper having a such a long range, he will rarely get hit by any of Silencer's spells.
* Global Silence will not hinder Sniper much as other heroes since most of his damage output comes from his attacks.
Additional:
* Sniper is a pure right click carry with a very long range, making it hard for Silencer to cast any of his skills on him in lane. During team-fights, 
Global Silence has little impact on Sniper.
Sniper
* Heroes with powerful nuke can waste their precious abilites on her Refraction during a ganking attempt or chaos combat: Lich, Lina, Sniper, Outworld Destroyer Zeus
Sniper
* Sniper destroys Templar Assassin 
Refraction's only defense with its Shrapnel ability, which is why it can easily punch it and kick it off the line, getting more level and gold.
* The huge range of Sniper's attack due to the Take Aim ability allows him to spend the whole game at a distance far from Templar Assassin, constantly punching her with his physical attacks, which is why Templar Assassin remains either to run away or hide in 
Meld, however, even there Sniper will not let her escape with the help of Blink Dagger, since he uses Shrapnel.

Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Sniper
* Take Aim and Assassinate allow Sniper to reach Io even if it stays in the backline.
Sniper
* Past the early game, Sniper is an easy target for Sven to jump on with Aghanim's Scepter upgraded 
Storm Hammer, Blink Dagger, Silver Edge or 
Harpoon, common items on Sven.
* Sven's high armor and health pool makes it difficult for Sniper to focus, as his main source of damage is his right click, especially if Sven uses 
Warcry.
* Sniper is very squishy, and will not stand a chance against Sven head on.
Lion
* Sven is very vulnerable to chain stun such as Lion, Shadow Shaman or Magnus.
Sniper
* Special mention to Sven as he may not be able to get close, but if he does, 
God's Strength will make very short work of Sniper.
Sniper
* Axe can easily close the distance to Sniper with Blink Dagger.
* With 
Berserker's Call in combination with 
Counter Helix and 
Battle Hunger, Axe can make short work of Sniper, finishing him off easily with 
Culling Blade due to his low HP & high attack speed in the late game.
Lion
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Sniper
* Ranged heroes that can easily harass Axe: Drow Ranger, Sniper, Lion.
Sniper
* Sniper's lack of mobility and reliance on attack range makes him an easy target for Phantom Assassin to jump on.
Additional:
* Stifling Dagger and 
Phantom Strike allow Phantom Assassin to close the gap with Sniper and prevent his escape.
* 
Blur allows Phantom Assassin to approach Sniper while invisible and dodge much of Sniper's damage. It can also disjoint Assassinate.
* 
Coup De Grace quickly cuts through Sniper's low health; one or two procs will usually kill him.
* 
Fan of Knives from Aghanim's Shard can deal damage to Sniper's maximum health and disable Headshot and Take Aim.
Lion
* Despite her high mobility, Hex or Earth Spike can lock Phantom Assassin down, make her vulnerable and mitigate her damage output.
* Lion relies entirely on his abilities to be effective, rendering Phatnom Assassin's high evasion through ineffective against him. And Phantom Assassin's low health pool makes her vulnerable to Lion's magical burst without Black King Bar.
Sniper
* Range-reliant heroes: Sniper, Drow Ranger
Lion
* Heroes with nukes: Bane, Lich, Lion, Skywrath Mage
Additional:
* Enchantress is very fragile without any form of magic resistance, allowing Lion to easily burst her down.
* 
Nature's Attendants is a slow heal, making not as much effective against Lion's burst as it could be.
* Her raw movement speed is a fair escape/mobility mechanism, which may allow her to avoid a blindly cast Earth Spike, but does nothing against the rest of Lion's abilities, since they are single target and can't miss.
* Since Lion's damage comes mostly from his skills, 
Untouchable does nothing to mitigate it.
Sniper
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, Lina, Rubick, etc.
Lion
* Heroes that can keep Marci for a long time in one place so she can't pursue her targets, like Bane, Lion, Shadow Shaman, Invoker, Disruptor and Kunkka.
Sniper
* Carry heroes who can close the gap reliably are very problematic: Phantom Lancer, Ember Spirit, Phantom Assassin.
Lion
* Lion may upgrade Mana Drain, Hex and Finger of Death through Talent Tree and Aghanim's itens to make them affect secondary targets or turn them into AoE abilities. This can make things difficult for heroes like Phantom Lancer, Naga Siren and Terrorblade, who rely on illusion armies.
Sniper
* Other heroes that rely on physical attacks to deal damage and not their abilities: Troll Warlord, Sniper, 
Monkey King, Sven.
Lion
* Since Windranger is bad against magical damage, heroes with continuous magical damage or magical nukes can blast her: Zeus, Tinker, Leshrac, 
Viper, Skywrath Mage, Lion, Lina, Venomancer.
Lion
* Luna can easily cancel channeling spells with 
Lucent Beam and 0.25s Eclipse Lucent Ministun talent for 
Eclipse, she can also buy 
Abyssal Blade in case they decide to buy Black King Bar: Enigma's Black Hole, Witch Doctor's Death Ward, Shadow Shaman's Shackles, Lion's Mana Drain, Bane's Fiend's Grip, Pudge's Dismember, Crystal Maiden's Freezing Field, Pugna's Life Drain, Dawnbreaker's Solar Guardian, and Naga Siren's Reel In from Aghanim's Scepter.
Sniper
* Heroes that outrange Luna can be a problem for her: Drow Ranger, Sniper.
Sniper
* Heroes with high mobility can approach Sniper: Anti-Mage, Earth Spirit, Io, Nature's Prophet, Pangolier, Puck, Queen of Pain and most notably Riki.
Lion
* High priority targets like Queen of Pain, Drow Ranger, Ember Spirit can't get caught out from Lion's long range disables, making it harder to them fulfill their roles, and making it easy to target them.
Sniper
* Ember Spirit can close the distance between Sniper easily with his 
Activate Fire Remnant and further keep Sniper in place with 
Searing Chains.
* With the help of Aghanim's Scepter, Sniper cannot outrun Ember Spirit or chase him, even if Sniper builds mobility items.
Lion
* Lion possesses two strong disables in Earth Spike and Hex and heavy magic burst with Finger of Death which help lock him down and prevent him from escaping with Activate Fire Remnant. When getting his Blink Dagger Lion can punish Ember Spirit's overextension immediately, or initiate a fight on him with disables.
Sniper
* 
Shukuchi allows Weaver to close the gap between himself and Sniper with high speed, and to maneuver through teamfights to get on top of him.
* A combination of 
The Swarm and 
Desolator tears through Sniper's low armor.
Lion
* Weaver's exceptional ability to elude and survive through clashes and ganks is hard countered by Lion in every aspect.
* Weaver is very mana dependent and has a rather small mana pool in the beginning of the game, of which Mana Drain can deplete and lessen his early game presence.
* Earth Spike followed by Finger of Death in the huge majority of the time is enough to kill Weaver.
* Earth Spike can be point targeted to hit through Shukuchi.
* Hex's has a fair long duration, by which Weaver will not be able to deal damage, or even survive a coordinated attack, and it is single target, of which cannot be dodged.
* Mana Drain easily breaks Linken's Sphere. Its low cooldown allows Lion to infinitely break it whenever it recharges.
* Earth Spike and Hex when paired for the longer lengths of disables may diminish 
Time Lapse efficiency, possibly causing Weaver to not undo as much damage as he would.
Sniper
* 
Shadow Step and 
Haunt from Aghanim's Scepter instantly allows Spectre to get up and close with Sniper, and 
Spectral Dagger makes it difficult for Sniper to escape from her.
Additional:
* Spectre can reach him easily in the backlines with Spectral Dagger or teleport to him with Haunt.
* He is usually a fair distance away from his allies, so 
Desolate will quickly tear Sniper down.
* 
Dispersion reflect or reduce his damage, making her hard to take down even at late game.
Lion
* Hex and Mana Drain can be used to immediately destroy Spectre's illusion when she Haunts. A fast fingered Lion can protect himself and a teammate.
* Hex and Earth Spike are good lockdown spells to control and kill Spectre, especially if she doesn't buy defensive items like Linken's Sphere and Black King Bar.
* Finger of Death can be used to burst down Spectre when she is low on life as she has very poor magic resistance.
Lion
* Lion lacks mobility or escape mechanisms, making him an easy target for abilities like Mirana's Sacred Arrow or Leshrac's Split Earth, or combos like Kunkka's X Marks the Spot into Torrent.
Lion
* Heroes with silences and hard stuns such as Doom, Silencer, and Lion can keep Mirana from Leaping away.
Sniper
* 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.
Lion
* Hex abilities can cancel the channelling of Fiend's Grip : Lion, Shadow Shaman, 
Dazzle from Aghanim's Shard with upgraded 
Poison Touch.
Sniper
* Morphling's high mobility allows him to easily get close to Sniper, who likes to keep his distance from enemies.
Lion
* Mana Drain rapidly saps Morphling's already low mana pool, making him unable to use Waveform or Adaptive Strike. Additionally, Hex prevents these abilities as well.
* An Earth Spike and Finger of Death combo can burst an unwary Morphling down if he has his strength fully shifted to agility.
Lion
* Heroes that deal few, powerful instances of damage, like Oracle, Lion, or Sven, have a hard time breaking through Gravekeeper's Cloak.
Sniper
* Heroes with long ranged attacks or abilities can harass Visage from afar like 
Phoenix and Sniper.
Lion
* All of
Lion's abilities are dangerous even to Lion himself, and 
Rubick may steal them with 
Spell Steal.
Arcane Supremacy powers up abilities cast range and damage, making 
Rubick better at using 
Lion's abilities than Lion himself.
Telekinesis can easily catch and disable 
Lion while also manipulating his position to favor 
Rubick and allies, rendering him helpless.
Earth Spike is a great crowd control ability for Rubick to use, extending his lockdown potential. 
Arcane Supremacy.
Earth Spike is limited to a straight line, making it harder to clear the creep wave.
Hex is one of the strongest single-target lockdowns in the game, and works exactly the same when casted by Rubick.
Mana Drain does not directly provide damage or lockdown, it does solve Rubick's mana regen issue in the early to mid game.
Finger of Death is one of the best magical nukes in the game, increases Rubick's ganking potential greatly.
Finger of Death is lost when Rubick lost the spell.
Aghanim's Scepter, Rubick can clear creep waves and flash farm with the boosted 
Finger of Death if stolen, assuming Rubick has enough mana pool to hold.

Sniper
* In the mid to late game, the physical attack from
Sniper can be painful to go through as 
Rubick. However with the help of Rubick's teammates, the abilities of 
Sniper can turn against his team.
Shrapnel is a great wave-clear ability, and helps with scouting the area.
Shrapnel already has a long cast range, and together with 
Arcane Supremacy Rubick can put constant damage on 
Sniper while he stays at back.
Assassinate, if stolen, can be cast to assist a gank while Rubick stays at a range that can merely be found in the area, damaging heroes in the backline including 
Sniper.
Arcane Supremacy (combined with Level 25 talent +40% Spell Amp For Stolen Spells, as of 7.31c) increases its damage before reduction to 406.2/611.1/819(531.2/805.1/1079) without considering any further amplification source.
Aghanim's Scepter, 
Assassinate becomes an ability with a reliable 1.5 second stun, massive damage, short cooldown and over 3000 cast range which should not be made light of.
Shrapnel is used frequently and can be easily stolen; 
Assassinate has a long cast animation for Rubick to forsee the chance to steal.
