Meepo
* 
Winter's Curse in late game is pretty much the end for Meepo or any of his nearby allies. Natural counter for Winter's Curse like 
Linken's Sphere or 
Lotus Orb is meaningless to her if she can land it on one of Meepo's clones.
Additional:
* Meepo's clones usually gets grouped in teamfight making any of them ideal target for Winter's Curse, forcing Meepo to literally kill himself. Also, unlike other heroes he cannot protect himself with Linken's Sphere.
* While Meepo's clones are grouped up, Splinter Blast will hit almost every clone, slowing Meepo and making him easier to fight.
Ogre Magi
* 
Winter Wyvern's Winter's Curse works very well against the increased attack speed from Bloodlust.
Meepo
* Besides 
Lone Druid and 
Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
Ogre Magi
* 
Doom makes Ogre Magi less disruptive.
* 
Infernal Blade effectively negates Ogre Magi's durability.
* With 
Aghanim's Scepter, he can disable Multicast.
Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as 
Enigma, 
Invoker, 
Magnus, 
Puck, and 
Sand King.
Ogre Magi
* Puck silences Ogre Magi with 
Waning Rift, and 
Phase Shift makes Puck untargetable for the duration.
Ogre Magi
* 
Heavenly Grace reduces Fireblast stun time and dispels Ignite.
* 
Purification can heal damaged heroes if needed.
Ogre Magi
* 
Fate's Edict gives full immunity from Ogre Magi's mostly magical damage.
* 
Fortune's End can dispel Ignite (when used on allies) and Bloodlust (when used on enemies).
* 
False Promise can dispel Ignite and Fireblast.
Meepo
* Poof won't damage Medusa and she can use Stone Gaze to disable all of Meepo's clones.
* Mystic Snake will easily become the bane of Meepo early game.
Meepo
* Meepo lacks the disengages to escape a well-timed Echo Stomp, in particular if Elder Titan is his current target.
* Clones are counted as heroes, increasing massively the power of 
Astral Spirit's buffs, including Aghanim's Scepter's spell immunity buff.
* Meepo relies heavily on high agility and his mediocre strength gain makes him a very prized target for Natural Order.
* Meepo and his clones like to group up to hunt and kill in teamfights or ganks and can be easily disabled together with Echo Stomp.
Additional:
* 
Echo Stomp can completely disable multiple Meepos for 5 seconds.
* Astral Spirit will affect Meepo clones, as they don’t count as illusions. Elder Titan can receive a massive amount of damage, armor and movement speed from each Meepo.
* With 
Natural Order, Elder Titan’s mere existence causes Meepo to be disadvantaged, due to the aura that completely negates his base armor and magic resistance. Combining Astral Spirit with Natural Order allows Elder Titan to easily kill any Meepo within a second, depending on how much damage he gains from Astral Spirit. This is highly detrimental for Meepo as he is prone to buying items that grant agility like 
Disperser and 
Eye of Skadi.
* 
Earth Splitter deals over 30%/40%/50% of each Meepo’s max hp, and is even stronger if the Meepos are near Elder Titan due to Natural Order.
Meepo
* With Nether Swap, Vengeful Spirit can isolate one of the Meepos, making him an easier kill for the team.
* Her Magic Missile gives her an easy way to cancel Meepo's 
Poof, preventing isolated Meepos from fleeing.
Meepo
* 
Lifestealer is not affected by Earthbind or Poof during 
Rage, making him a difficult target to work around.
Ogre Magi
* Lifestealer's Rage makes him immune to all of Ogre's magical debuffs and also dispels them.
* Ogre's high health pool makes him an ideal target for Feast.
Additional:
* Ogre Magi has nothing against Rage and his high health pool amplifies 
Feast.
Meepo
* Lifestealer's Rage and Open wounds become useless when Meepo has 4 or more clones, as Ransack will heal Meepo too quickly for Lifestealer to take down.
Meepo
* Dark Seer can take great advantage of 
Divided We Stand by putting an Ion Shell on a clone in order to harass them effectively.
* Vacuum can take a single Meepo and disable him for Dark Seer and his teammates to take out.
Meepo
* Poof combo puts all of the Meepos very close together, making them vulnerable to Frost Blast's AoE slow and multiple bounces from Chain Frost.
Meepo
* Every Meepo clone adds to Thirst's bonuses.
* Bloodseeker can chase down retreating clones when Meepo tries to cycle weaker clones away from combat.
Meepo
* Light Strike Array can catch Meepo and his clones off-guard if he tries to gank Lina with 
Earthbind & Poof.
* Laguna Blade can quickly kill Meepo and his clones before they escape with Poof.
Meepo
* Fatal Bonds links the Meepos together, which combined with area of effect damage or Cleave will be devastating.
Meepo
* X Marks the Spot is good to prevent a single meepo from escaping from a deadly situation.
* Tidebringer, Torrent and Ghostship destroys Meepo's clones.
Additional:
* 
Tidebringer's cleave damage can wear down Meepo's clones quickly. It can also give Meepo problems in the lane, due to his melee range and initially low health pool.
* 
Ghostship and 
Torrent can effectively disable Meepo while dealing heavy damage.
* 
X Marks the Spot prevents attempts to escape using Poof.
Meepo
* 
Focus Fire can quickly attack target Meepo or clones instanly. Additionally, Windranger can use combinated 
Shackleshot and Focus Fire since Poof wrong landing and stunned from Shackleshot affected Meepo and clones collateral damege from Focus Fire.
* Escaping from 
Windrun make Earthbind roots can not reach.
Meepo
* Pulse Nova deals an insane amount of damage in an area around him, which can quickly wear down Meepo clones.
* Leshrac can catch multiple Meepos in Split Earth and follow up with the rest of his area damage spells making Meepo unable to get close to Leshrac.
* Diabolic Edict is a strong ability that can wear down a lone Meepo clone quickly.
Meepo
* Casting Bramble Maze on top of Meepo guarantees a root, as it is nearly impossible to leave the thorns with all of Meepo's clones.
* Terrorize and Cursed Crown offer great disables against the grouped Meepos and can prevent them from using Poof to escape.
Meepo
* All of Jakiro's skills are Area of Effect, which can easily affect all Meepos in a targeted area.
Meepo
* Because multiple Meepos tend to clump up, they present an easy target for Timbersaw's many area abilities.
* Although be careful since Timbersaw cannot use 
Timber Chain to escape if rooted from Earthbind.
Meepo
* If Meepo ganks Lion with Poof and Earthbind, he will be an easy target for 
Earth Spike & AoE 
Hex from his level 25 talent.
Ogre Magi
* 
Phantasm dispels Ignite and makes targeting the real Chaos Knight much harder.
Meepo
* Flak Cannon and Call Down will shred Meepo's clones.
* Homing Missile can catch and single out retreating Meepos, making them an easy kill.
Meepo
* Meepo is vulnerable to area damage and disables from Magnus himself as well as his team through Empower.
Meepo
* Quill Spray usually hits Meepo's clones, although Bristleback cannot turn his back when rooted with Earthbind.
Meepo
* Aggressively Poofing and Earthbinding is not going to end well against Venomancer, as he will be an easy target for 
Noxious Plague.
* Venomancer's constant slows greatly reduce Meepo's mobility.
Meepo
* 
Tree Dance and 
Primal Spring allows him to chase a retreating Meepo.
* 
Boundless Strike gains critical strike bonuses and 
Wukong's Command can take down Meepo and his clones very quickly.
Additional:
* Monkey King can gain 
Jingu Mastery stacks on Meepo’s clones from Divided We Stand.
* Tree Dance allows him to sneak up on and gank a lone Meepo clone.
Meepo
* 
Reactive Tazer can lock multiple Meepos in place and prevent them from Poofing.
* 
Proximity Mines, 
Sticky Bomb and 
Blast Off! can deal heavy magic damage to multiple Meepos.
Meepo
* Flaming Lasso is the perfect tool to isolate a single Meepo and focus him.
Ogre Magi
* In general, heroes that deal burst in multiple instances will trigger Borrowed Time and heal Abaddon for a large amount, such as 
Skywrath Mage, 
Techies, 
Juggernaut, 
Shadow Shaman, or 
Ogre Magi.
Meepo
* Heroes without blink mechanisms or spell immunity will have a hard time positioning against 
Pit of Malice: 
Sven, 
Tiny, 
Wraith King, 
Dragon Knight, Meepo, 
Doom, 
Bounty Hunter, 
Dark Seer, 
Undying, 
Alchemist, 
Legion Commander.
Meepo
* Melee heroes who rely on summons, illusions, or clones will trigger Counter Helix more often, thus taking more damage: Meepo, 
Lycan, 
Phantom Lancer
Additional:
* The combination of 
Counter Helix and 
Berserker's Call can disable multiple Meepos and deal heavy area damage.
* Axe's natural high survivability makes it difficult to burst him down with Poof or chip away at his health with Ransack.
Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.
Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.
Additional:
* Burrowstrike can stun multiple Meepos, making them vulnerable targets.
* Epicenter and Sand Storm's AoE damage ensures all Meepo clones get damaged, making it hard for Meepo to choose which one to flee as all are taking damage at the same rate.
* Just be aware when using Sand Storm to escape, as Meepo has good AoE damage and disables, which, as explained in the "Bad Against" section, works well against an invisible Sand King.
Meepo
* 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.
Meepo
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as 
Batrider, 
Beastmaster, 
Pudge and 
Clockwerk.
Meepo
* Troll Warlord can root and deal a lot of damage to a single Meepo while lifestealing through the assault from the other Meepos. Meepo needs expensive items like 
Ethereal Blade or 
Heaven's Halberd to be able to fight him.
Meepo
* Heroes who can stun multiple units at once: 
Dark Willow, 
Spirit Breaker, 
Slardar, Invoker, and 
Tidehunter.
Meepo
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.
Meepo
* Shadow Fiend's Requiem of Souls not only slow all Meepos, but it can also kill the weakest Meepo instantly if the ultimate is released at the right position and time.
Additional:
* Shadow Fiend can easily focus down and kill one of the Meepos.
* The amount of damage from Shadow Fiend's AoE spells makes Meepo vulnerable in every aspect.
Meepo
* Tiny's Avalanche affects all Meepos and Toss can send a singular Meepo into death.
Additional:
* Avalanche and Toss prevents Meepo's from using Poof to escape.
* Tiny doesn't need to target the weakest clone while he is affected by Tree Grab.
Meepo
* Heroes with powerful area-of-effect disables can initiate on Meepo and his clones and shut him down, such as Enigma, Invoker, Magnus, Puck, and Sand King.
Meepo
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and Clockwerk.
Meepo
* Meepo is quite fragile in the early game and can be easily taken down by Flame Guard's and Searing Chains' damage. Later on, Meepo is very vulnerable to Sleight of Fist's damage due to 
Battle Fury's cleave on multiple Meepos.
Additional:
* 
Sleight of Fist combined with Battle Fury, 
Maelstrom and 
Daedalus will allow Ember Spirit to make a quick work of Meepo if his clones are crowded around each other.
* 
Searing Chains interrupts Meepo's initiating because Meepo's clones do not have spell immunity.
Meepo
* 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
Ogre Magi
* Undying saps strength from heroes with Decay, and Ogre Magi's high strength gain will allow Undying to steal more and more strength, becoming stronger with each use.
* Due to the Strength steal from Decay, Undying is normally very tanky, and has high health, making it harder for Ogre Magi to kill him.
Meepo
* Meepo can quickly destroy Tombstone thanks to Divided We Stand.
Ogre Magi
* 
Dark Pact dispels Ignite's slow and Fireblast's stun.
* 
Shadow Dance allows Slark to regenerate HP, even when he is affected by Ignite and Fireblast.
Meepo
* Slark's Dark Pact and Pounce can deny only one Earthbind and Poof can penetrate Shadow Dance if he doesn't build Black King Bar.
Additional:
* Earthbind and Poof will still hit Slark in Shadow Dance.
* Dark Pact can only remove one Earthbind.
* 
Ransack will still affect Slark, even if he has a 
Black King Bar.
Meepo
* Pangolier's arsenal deals heavy damage in a wide area, make him deadly even for a Meepo with a high magic resistance.
* 
Shield Crash can easily give him a ridiculous 80% damage resistance (Becomes 100% if Pangolier gets his +5% Shield Crash talent, Or there is 5 Meepos), resulting in a near unkillable Pangolier in a short amount of time.
* 
Rolling Thunder disrupts Meepo's initiation or escaping.
* 
Swashbuckle can hit all of Meepo clones.
* 
Lucky Shot can disarm Meepo's clones.
Additional:
* Shield Crash gains its damage reduction bonus from all Meepo clones, and can be used even when rooted, allowing Pangolier to gain a massive amount of damage reduction (even more than 100%).
* With too many clone running around during combat, it is almost impossible for Meepo to avoid Rolling Thunder or Swashbuckle.
* Still, remember that a lone Pangolier can never escape from a ganking Meepo.
Meepo
* Heroes with powerful rooting abilities will disable most of Pangolier's skills, a bonus point if it pierces spell immunity since it will also be able to stop Pangolier during his Rolling Thunder: 
Treant Protector, Meepo, 
Crystal Maiden, Dark Willow, 
Underlord, 
Naga Siren
Meepo
* Multiple attackers thanks to summoned units or clones: Meepo, 
Witch Doctor, Lycan, Enigma, Shadow Shaman
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo, Witch Doctor, Lycan, Enigma, Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer, 
Chaos Knight, Naga Siren (bonus for her 
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark, Gyrocopter, 
Queen of Pain, Shadow Shaman (
Shackles), 
Jakiro, 
Pugna, Doom
Ogre Magi
* The damage block instances of 
Refraction can be burned down with Ignite.
* Fire Shield effectively reduces the burst damage from a 
Meld-charged ambush from Templar Assassin, provided the spell is cast beforehand.
Meepo
* Nature's Prophet is heavily countered by Meepo, not only Meepo can kill the treants with a single Poof, but he can also stop Nature's Prophet from using 
Teleportation, and can gain vision inside 
Sprout.
Additional:
* Meepo can net Nature's Prophet's treants with Earthbind and then Poof them, putting an end to his pushing.
* Skilled Meepos can rival and even exceed Nature's Prophet's global presence by combining Poof with 
Boots of Travel, meaning that he can not only stop his push, but also can kill him if he is not careful.
Ogre Magi
* Nature's Prophet treants can be cleared by Ignite or Multicast 
Hand of Midas
* Fireblast and Unrefined Fireblast prevents Nature's Prophet from using Teleportation.
Meepo
* 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
Ogre Magi
* A well-timed Fireblast with Multicast can prevent Weaver from escaping with 
Shukuchi and even 
Time Lapse.
* Ignite's high damage early on applies heavy pressure onto Weaver's very small health pool.
* However, the slow from Ignite is generally useless against Shukuchi, and Time Lapse dispels it if needed.
Meepo
* Earthbind disables Waveform, effectively keeping Morphling in place for an extended period of time, allowing Meepo to deal considerable damage with Poof.
Meepo
* Thundergod's Wrath strikes only the first Meepo.
* Zeus has low mobilty so consecutive Earthbinds are easy to hit and he'll quickly die from Poofs.
Meepo
* Earthbind, like any root, inhibits usage of 
Ball Lightning, eliminating Storm Spirit's mobility.
Meepo
* Necrophos struggles at clearing away durable illusions or summons. Meepo can overwhelm Necrophos with his many duplicates, especially in the later stages of the game, and his Earthbind will prevent Necrophos from getting away, even if he casts Ghost Shroud.
* Meepo's high burst damage from Poof can make it difficult for to Necrophos to stay alive, and as Necrophos excels in extended fights, he will not be able to do as much damage as he intends to.
Meepo
* Chain of Earthbinds prevents her from using 
Blink, allowing Meepo to quickly kill her with Poof and attacks.
* Meepo tends to buy items with attributes, mitigating Queen of Pain's magical burst.
Additional:
* Meepo is the hard counter for Queen of Pain - chaining Earthbinds prevents her from using Blink for a long time, and without any other escape options, Queen of Pain cannot survive several Poofs and attacks.
* Meepo tends to build items with attributes, mitigating Queen of Pain's magical burst.
Meepo
* Earthbind can prevent Phoenix from using 
Icarus Dive, the only escaping mechanism of this hero.
* Heavy burst damage from Poof can easily kill Phoenix even when it slows down all the Meepos with 
Fire Spirits.
* Meepo's clones destroy the Phoenix Sun from 
Supernova in no time, even when they are slowed down by Fire Spirits.
* Meepo's naturally high magic resistance gives Phoenix a hard time with bursting him down. He can even turn the tide if Icarus Dive is on cooldown.
Additional:
* Meepo is unlike any other multi-unit enemy Phoenix may face in the battlefield. Unlike illusion-based heroes like Phantom Lancer or Chaos Knight, Meepo's clones are not illusions, meaning they can deal full damage to the Phoenix Sun if all four (or five) are present.
Meepo
* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.
Meepo
* Earthbind's root prevents/interrupts Charge of Darkness.
* As a single-target focused hero without much damage output, Spirit Breaker is ineffective in general against Meepo.
Ogre Magi
* Heroes that can cancel Charge of Darkness: Ogre Magi, 
Earthshaker, 
Lion, 
Rubick, 
Lina, 
Luna, Jakiro, 
Dawnbreaker, Alchemist, Ogre Magi, 
Axe, Shadow Shaman, Naga Siren, 
Mars, 
Bane, Pudge, Clockwerk.
Meepo
* 
Void Spirit can dodge Earthbind with 
Dissimilate and 
Astral Step, giving him a good chance to escape. If he gets caught anyways, 
Resonant Pulse allows him to retaliate.
Meepo
* Meepo's Earthbind can easily lockdown Void Spirit.
* Meepo and his clones can easily burst Void Spirit's Resonant Pulse.
Ogre Magi
* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.
Meepo
* Poof will destroy Shadow Demon's illusions created by 
Disruption and quickly escapes from 
Shadow Poison & 
Demonic Purge.
Meepo
* Earthbind prevents Broodmother from escaping Meepo's attacks.
* Poof will quickly clear any nearby spiders.
* Broodmother often picks off single target heroes. With Meepo's Divided We Stand, it gets a lot harder once every Meepo Poofs in.
Meepo
* With all 5 Meepos available, all of Shaman's wards will be disposed of very quickly.
* All of Shaman's disables are based around single target control, and he can at most only disable two Meepos, allowing the rest to easily lay waste to him, be it during the channel duration of Shackles or by using Earthbind.
Meepo
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during 
Mortimer Kisses and dodge the projectiles easily due to their slow speed.
* Heroes with mobility spells (such as Queen of Pain's Blink and Clockwerk with 
Hookshot) can easily avoid 
Lil' Shredder and Mortimer Kisses.
* Heroes with high movement speeds like Pugna and Meepo can run around, to, or away from Snapfire during Mortimer Kisses and dodge the projectiles easily due to their slow speed.
Meepo
* Mirana cannot use Leap while rooted by Earthbind and her Moonlight Shadow is countered by Meepo's true sight that is provided by Earthbind.
Additional:
* Earthbind prevents Mirana from Leaping or going invisible with Moonlight Shadow. She can be easily killed by Poof and Ransack while disabled.
* Landing a Sacred Arrow on Meepo does not render him helpless, as all of the other Meepos can still fight back.
Meepo
* Naga Siren's Song of the Siren may be useful but Poof will destroy all of her illusions.
Meepo
* 
Spectre's Haunt with Radiance may be useful for countering Meepo but if Meepo finds the real one, Spectral Dagger is useless. Non-Black King Bar heroes like her will suffer from all of Meepo's abilities. Meepo is also a very large counter as Spectre takes a long time to come online, normally farming in the jungle or in lane, which makes her an easy target for Meepo ganks.
Additional:
* Poof combined with Earthbind can be used to easily lockdown and burst Spectre down.
* As Meepo's playstyle is often to come online early to mid game and take over the whole game, Meepo will often be much further ahead of Spectre in farming.
* Meepo's global map presence allows him to effectively hunt for Spectre and disrupt her farm.
* Spectre has no strong AOE abilities or way to control or lock down Meepo.
Meepo
* Heroes that can jump and kill him: Meepo, Clinkz, 
Templar Assassin
Meepo
* Pugna's Nether Ward doesn't really hurt Meepo since he usually buys attribute items to tank up and can be killed very quickly by 4 clones. Decrepify can amplify Poof's damage should Pugna use it to avoid Meepo's right clicking.
Ogre Magi
* Supports who can slow him to the point Trample does very little damage in the lane are also not fun: 
Lich, Ogre Magi, Winter Wyvern.
Meepo
* 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.
Meepo
* Juggernaut's Omnislash is meaningless for Meepo who can share the damage across clones to save other allies.
Meepo
* 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
Meepo
* Skywrath Mage's abilities are single targeted and he can't use Mystic Flare to its fullest potential, since all Meepos spread the damage between them. He also has no disables to prevent Meepo from Poofing to another one (unless he can get 
Ancient Seal off first).
Meepo
* Meepo has a better advantage in farm with Divided We Stand, as well as having a higher attack speed due to his tendency to build items that give attributes. In addition, Wraithfire Blast stuns only one target, and choosing to engage one Meepo will most certainly mean engaging them all.
Meepo
* 
Night Stalker's most skills are single targeted which allows other Meepos to Poof, Earthbind and kill him.
Meepo
* Heroes that can overwhelm Visage by sheer number like Chaos Knight, Meepo, Terrorblade and Phantom Lancer.
Meepo
* 
Tinker who can't fight multiple heroes will suffer greatly against Ransack and Earthbind.
Meepo
* 
Enchantress's 
Untouchable slows down Meepos attacks and 
Impetus can deal heavy pure damage to a single Meepo, however once Meepo has closed the gap she is an easy target for Poof.
Meepo
* Meepo can quickly kill Enchantress with a Poof combo, rendering Untouchable useless.
Meepo
* Heroes who can stun multiple units at once: Dark Willow, Spirit Breaker, Slardar, Invoker, and Tidehunter.
Meepo
* Slardar does not do well against multiple targets, as his only way to damage multiple targets is Slithereen Crush.
* Meepo's Earthbind will root Slardar, making him unable to chase/escape for the time being. Also, Poof's low cooldown and high damage can burst Slardar down rather quickly.
Meepo
* Illusions and summons are double-edge sword type of matchup for Luna. On one hand, they can tank damage from Eclipse, but on the other hand, she can easily clear them before Eclipse with Moon Glaives. Examples include Spectre, 
Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, Terrorblade) or bring other units into the fight (such as Nature's Prophet, Lone Druid, 
Chen, Enchantress, Meepo and 
Arc Warden).
Meepo
* Even though Moon Glaives can bounce between Meepo and his clones, Meepo can tank Eclipse because of his clones.
* Earthbind takes away Luna's mobility advantage.
* Meepo can shutdown Luna's split-push ability with his global presence.
* For the same reasons, Meepo makes a very powerful ally for Luna when they are in the same team.
Ogre Magi
* Heroes rely on their debuff to control the opponent will have a hard time against Press the Attack: 
Venomancer, Earth Spirit, Ogre Magi
Meepo
* When Legion Commander uses 
Duel on one Meepo, he can use his other Meepos to kill her. If he wasn't dueled, he can help the teammate who was duelled to give the teammate the damage instead of Legion Commander.
* However, if Legion Commander picked up an Aghanim's Scepter and she duels one Meepo, that might be the end of Meepo if Legion managed to gather enough damage from previous duels.
Ogre Magi
* Arc Warden's 
Tempest Double is helpful for killing Ogre Magi who lacks AoE damage and disables.
Meepo
* Flux is severely impaired against Meepo because of Divided We Stand.
* Meepo's farming speed and early powerspikes allows him to pressure Arc Warden before he is capable of fighting effectively.
* Without Black King Bar, Earthbind and Poof can finish Arc Warden quickly before he has time to do much.
Ogre Magi
* Ogre Magi has no undispellable AoE damage or disables and has nothing to deal with Phantom Lancer's illusions.
* 
Doppelganger disjoints and dispels Ignite.
Meepo
* Poof will destroy Phantom Lancer's illusions within a short time.
* Earthbind prevents Phantom Lancer from using Doppelganger.
Additional:
* Poof from multiple Meepos will destroy illusions quickly.
* Earthbind's area root can catch Phantom Lancer in a group of illusions and prevent him from using Doppelganger for a long time.
* Meepo aims to end the game as early as possible, while Phantom Lancer is a lategame hero.
* This also means that, in the late game, Meepo stands no chance against Phantom Lancer.
Meepo
* Heroes that have doubles or clones such as Arc Warden, Meepo or Lone Druid are vulnerable to Muerta's 
Gunslinger.
Ogre Magi
* Heroes that commonly attack ethereal units will not have any problems against Muerta's Pierce The Veil: Tinker, Jakiro, Lina, Luna, Pugna or Ogre Magi, Enigma, Batrider, Techies, 
Broodmother, Dawnbreaker, Shadow Shaman, Bane, Tinker, Venomancer, Arc Warden.
Meepo
* 
Bulwark blocks the attack from Meepo and his clones.
* 
Spear of Mars & 
God's Rebuke prevents Meepo and his clones from initiation or escaping.
Ogre Magi
* It is difficult for Mars to trade blows with Ogre Magi in the early game thanks to his high base health, resistance and 
Ignite.
* 
Bloodlust can assist Ogre Magi or an ally in repositioning against Mars for its move speed bonus.
* 
Fireblast can interrupt and mitigate Mars from performing his skill combos, especially in combination with 
Multicast.
Ogre Magi
* Ogre Magi only deals magical damage, which Anti-Mage is exceptionally resistant due to Counterspell.
* Anti-Mage dispels Ignite with 
Manta Style.
* Ogre Magi has a very large mana pool which means Anti-Mage can do large amounts of damage to him with Mana Break and Mana Void.
Additional:
* Anti-Mage can kite Ogre Magi who has low mobility by 
Blink and his intelligence gain and build making 
Mana Void deal more damage.
* 
Counterspell well timed makes harass Fireblast and Ignite.
Meepo
* Multiple Earthbinds allows Meepo to lock down Anti-Mage almost indefinitely.
* Meepo's clones can only use their mana for Poof, keeping their mana pool nearly full and thus making them a bad target for a Mana Void.
Additional:
* Earthbind can prevent Anti-Mage from using Blink, allowing Meepo to kill him with attacks and Ransack.
Meepo
* Tether helps Io escape from Earthbind even if Meepo has Blink Dagger.
* Io's Spirits can pressure Meepo while laning and will usually hit at least one of his clones.
Ogre Magi
* Fireblast is a good tool to interrupt Io during its escapes through 
Tether.
* Ignite can be one of the few spells with enough total damage to out-trade the sustained healing Io provides for its fellow laner.
* However, picking other supports that focus less on the laning phase is generally a better choice against Io.
Ogre Magi
* Earth Spirit's useful kit of Slows, Stuns, and Silences can set up kills on Ogre Magi and the silence can stop him from using his abilities.
Meepo
* 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
Meepo
* Each of Meepo's clones count as real heroes, meaning that an Echo Slam hitting them will deal catastrophic damage to Meepo and his team.
* Eathshaker's AoE stuns can interrupt Meepo's Poof cast animation.
Additional:
* 
Echo Slam will deal catastrophic damage against a cluster of Meepos and anyone nearby.
* 
Aftershock allows Earthshaker's abilities to potentially stun any number of Meepos for a fairly long duration, often enough to finish one off.
Ogre Magi
* Ignite can prevent Earthshaker from escaping and/or initiating with 
Blink Dagger.
* Fireblast and Unrefined Fireblast may help prevent Earthshaker follow through with his combo after landing an Echo Slam.
Meepo
* 
Great Cleave and 
God's Strength can take down Meepo and his clones very quickly.
* The lack of spell immunity for Meepo's clones makes them vulnerable to 
Storm Hammer.
Additional:
* Great Cleave will devastate Meepo's clones. Against a closely packed group, Sven does not even need to target the clone with the lowest health.
Ogre Magi
* Multicast Fireblasts over the course of fights are a decent nuisance to stall Sven's massive damage output.
* Bloodlust and Ignite gives Ogre Magi's team the movement speed difference needed to chase and/or disengage against a Sven and his 
Warcry.
* Ignite provides strong damage over time to pressure Sven early on in the laning phase and keep his health low, delaying his transition into the jungle. Ignite is also an easy way to disrupt Blink Dagger, Sven's most popular way of initiation.
* Ogre Magi's presence in the laning phase both in terms of damage and durability keeps high pressure on Sven in lane.
* Purchasing an 
Aghanim's Shard allows Ogre Magi to greatly reduce the burst damage of Sven, who tends to build items focused on damage per hit instead of attack speed.
Meepo
*
Viper Strike prevents the lifesteal from Ransack.
Poison Attack & 
Viper Strike directed onto one clone.
* Meepo and his clones have a lack of magic resistance, so they're vulnerable to
Ogre Magi
*
Viper Strike breaks Multicast.
Corrosive Skin minimizes the damage from Ignite and Fireblast.
