Elder Titan
* 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.
Marci
* Warlock has strong counter initiation which reduces Marci's effectiveness throughout the game.
* 
Fatal Bonds cancels 
Blink Dagger, which means Marci can move in and out of fights less effectively.
* 
Chaotic Offering paired with 
Upheaval provides a ministun, a movement slow and paired with Fatal Bonds has the potential to deal a lot of damage to Marci while she jumps on a target. The ministun also means that Marci will have a harder time casting Rebound. If Warlock does build 
Aghanim's Scepter and 
Refresher Orb, the physical damage from Golems will overwhelm Marci, especially when played as a support.
Elder Titan
* 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.
Marci
* 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.
Marci
* Unleash ensures that Axe's 
Counter Helix procs many times, even if he is stunned by Dispose.
* 
Aghanim's Shard allows Counter Helix to reduce the attack damage of anyone it strikes. Combined with Unleash causing to proc frequently, Marci will not be dealing significant damage as she attacks Axe over time.
* Axe doesn't worry about the damage from Unleash if he activates 
Berserker's Call beforehand. If he had activated 
Blade Mail or 
Mjollnir (or even both) as Marci attacks him, he will turn Unleash's high attack speed and damage against her.
* Usually, Axe would prefer to jump on his opponent to be more effective. Rebound does Axe a favor, bringing Marci within his most effective range.
Elder Titan
* 
Storm Hammer interrupts Echo Stomp.
Marci
* Lifestealer's 
Rage renders him immune to all of Marci's disables and magic damage for a good duration.
* His passive 
Feast deals bonus damage based on the enemy's max health and heals for the same amount. As a tanky Strength hero, Marci's own strength will be her undoing as well.
Elder Titan
* 
Frost Shield helps offset the armor reduction from Natural Order.
Marci
* 
Rupture ruins her only movement ability, Rebound. Combined with its high movement speed and her being unable to interrupt it once its cast, using it under the effects of Rupture will surely deal incredibly immutable damage, if not kill her.
* As a Strength hero, Marci naturally has high HP. Rupture's initial damage uses her high HP as a catalyst to deal damage depending on her current health, dealing a good amount of damage if she's full HP or forcing her to stop if she's low.
* With Aghanim's Shard, 
Bloodrage will now deal pure damage and lifesteal based on the opponent's max health. Her high HP as a Strength hero ensures that Bloodseeker will always deal significant attack damage and sustain himself a lot whenever he attacks Marci.
* If Marci doesn't build 
Black King Bar, Bloodseeker's 
Blood Rite will prevent her from using all of her spells which she relies quite heavily on. Her only dispel is tied to Sidekick with level 25 left talent.
Elder Titan
* 
Battery Assault's continuous mini-stun makes it hard for Elder Titan to cast his spells due to his poor cast animation.
* Elder Titan's channelling with Echo Stomp makes a good setup for 
Hookshot if timed correctly.
Elder Titan
* All of his spells can stun Elder Titan and interrupt Echo Stomp's channeling thanks to 
Aftershock.
* 
Fissure is particularly good for that purpose thanks to its long range.
* Elder Titan relies heavily on his spells and a chain-stun combo will usually be followed by certain death.
Marci
* 
Spirit Siphon exploits her naturally high HP to deal a good amount of DPS. She may break the link with Rebound, but 
Silence covers that problem.
* Marci's poor armor makes her vulnerable to 
Exorcism.
Marci
* Marci's Dispose is blocked by 
Linken's Sphere which is a common item for Weaver.
* 
Shukuchi allows Weaver to escape from 
Rebound slow.
* 
The swarm beetle require 4 hits to kill. Weaver can use it on her when she use Unleash. This give Marci a hard choice: ignore The swarm and her armor keep decreasing or kill the beetle and wasting 4 attacks of Unleash.
Elder Titan
* 
Blade Fury makes Juggernaut immune to Elder Titan's stun, so there is a high chance he wont get caught in your ultimate although Earth Splitter pierces spell immunity.
Marci
* 
Bramble Maze will very likely catch Marci midair, disabling Marci's chasing/fleeing ability.
* 
Shadow Realm prevents Marci from bursting Willow down since she relies on physical attacks and unit target spells. With Aghanim's Scepter, Willow can hit Marci while Marci can't hit Willow.
* 
Bedlam and 
Eul's Scepter of Divinity allows Willow to manfight if Marci initiates with Rebound.
* 
Terrorize and 
Cursed Crown combo can waste Marci's ultimate for almost half of its duration.
Elder Titan
* {U:Earth} has passive 
Spell Immunity, allowing him to walk into the Echo Stomp radius to stun Elder Titan with his 
Hurl Boulder.
* {U:Storm}'s 
Cyclone can cancel the channeling of Echo Stomp and take Elder Titan out of the fight for {show:A|Storm|Cyclone|value2} seconds.
Marci
* 
Death Pulse and 
Ghost Shroud very effective against her physical damage.
* 
Heartstopper Aura and 
Reaper's Scythe are very effective against tanky Strength hero Marci.
Marci
* 
Howl reduces a good chunk of Marci's attack damage that she relies heavily on, and the armor reduction works better on her because of her low armor.
* 
Shapeshift renders Lycan immune to slow from Rebound and Unleash.
Marci
* Pangolier's 
Lucky shot disarms her if procs making Unleash useless.
* 
Swashbuckle have a lower cooldown than Rebound so Pangolier can out maneuver her quite easily.
Additional:
* Pangolier's Lucky Shot disarms her if it procs, making 
Unleash useless.
* Swashbuckle will easily burn away Marci's already low mana pool with 
Diffusal Blade, an item commonly built on Pangolier.
* Swashbuckle's cooldown is shorter than Rebound, making it easy for Pangolier to outmaneuver her.
* Marci will get stunned if she tries to use Rebound while Pangolier is using Rolling Thunder, somewhat hindering her mobility in teamfights.
Elder Titan
* Infernal Blade deals scaling damage and is useful against high HP targets such as Elder Titan. It also can interrupt 
Echo Stomp if quick enough.
* Doom has very low base armor and naturally high HP, so he isn't significantly affected by 
Natural Order.
Marci
* Heroes that can reliably kite out Dispose, Unleash and dodge Rebound, like 
Ember Spirit, 
Void Spirit, 
Storm Spirit, 
Anti-Mage, 
Faceless Void, 
Puck or always build items like Blink Dagger and 
Force Staff.
Marci
* 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.
Additional:
* Shadow Shaman can provide an excellent counter-initiation against her Rebound. His abilities can shut down any of her tower dive attempts in the laning phase.
* Shackles keeps Marci stunned for an extended time, wasting her ultimate. A combo with Mass Serpent Ward only makes things worse for her, as her armor is low.
Marci

Marci
* Heroes that reduce the damage that Marci can deal during her ultimate, like 
Razor, 
Rubick, Bane, 
Dragon Knight and 
Underlord.

Marci
* 
Fortune's End dispells Marci's 
Sidekick, removing additional damage and lifesteal.
* 
Fate's Edict disarms Marci, preventing her from attacking with Unleash. Also it is useful against Marci or her ally affected by Sidekick.
* 
False Promise is a great tool to save an ally focused by Marci.
Elder Titan
* Elder Titan's Echo Stomp can turn into a 5 second stun on an ally under the effect of False Promise, as it delays all damage and makes it impossible to break the damage threshold of Echo Stomp.
Elder Titan
* 
Astral Spirit can give Elder Titan a lot of damage and movement speed if Nature's Prophet sends all of his Treants together.
* Not only does Echo Stomp prevent Nature's Prophet from escaping using Teleportation, but Astral Spirit can be used to bypass Sprout and cancel Teleportation with it's own Echo Stomp from long distances.
* 
Earth Splitter can clear Nature's Prophet's Treants effectively.
Marci
* 
Sprout can't stop her to Rebound.
* Treants can be used as targets for Rebound and Dispose as well.
Elder Titan
* Morphling's high armor is primarily from morphing agility, which is reduced by Natural Order therefore making the hero very vulnerable when it has morphed a lot into agility.
* Morphling usually will Morph into high agility and low strength. This can be taken advantage of with a good stun or silence or by bursting him down before he has the time to Morph back to strength.
* Morphling is very vulnerable to Blade Mail under Natural Order and can easily burst himself down with his own auto-attacks or his magical damage combo.
Additional:
* Most of Morphling's armor comes from his high agility and it is reduced by Natural Order.
* However, the aura has only 350 range and Elder Titan can be bursted down by Morphling's nuke combo if he isn't careful.
Elder Titan
* Phantom Lancer's lack of disables makes it hard for him to stop Echo Stomp's channelling.
* However, due to the long cast time of his abilities, a good Phantom Lancer can use 
Manta Style and/or 
Doppelganger to dodge the abilities.
* Phantom Lancer's high agility and relatively low strength make him very vulnerable to Natural Order.
* Additionally, Echo Stomp and Earth Splitter can clear his wave of illusions.
* Should Phantom Lancer tries to increase his health by investing for 
Heart of Tarrasque, Earth Splitter does more damage to him and his illusions.
Elder Titan
* Elder Titan's Astral Spirit ability gives him bonus damage for each converted creep it passes through.
* Echo Stomp and Earth Splitter will often kill him or any of his allies quickly before he has time to use Hand of God.
Elder Titan
* Terrorblade has a high base armor, and relies on many ultimate orb-based items (Manta Style and 
Eye of Skadi). Natural Order affects armor gained from agility, essentially reducing armor to zero if all armor is gained from agility. That effect combined with Terrorblade's low health can make a Elder Titan with an early value point in Natural Order a dangerous foe.
* Terrorblade's illusions are often grouped up in teamfight, making them more vulnerable to Echo Stomp.
Additional:
* Echo Stomp and Astral Spirit allow Elder Titan and his team to coordinate a kill on Terrorblade before he can use 
Sunder.
* Natural Order cripples Terrorblade's armor that he crucially needs to survive due to his low strength gain. This is very detrimental for Terrorblade as he is prone to buying items that require 
Ultimate Orb like Manta Style and Eye of Skadi.
* Echo Stomp and Earth Splitter will often kill Terrorblade before he can use Sunder, and will also kill his illusions.
Marci
* Rebound allows her to jump in or out of the 
Arena Of Blood. She can save her allies from the Arena with Dispose as well.
Marci
* Marci on the midlane will win the laning phase against Zeus almost every time, as her powerspike at level 6 will decimate Zeus' low health pool and force him to stay far back.
* Even before level 6, Dispose and Sidekick can easily take half of Zeus' health if he is in range of Dispose.
Elder Titan
* Natural Order aura prevents Slark from gaining armor from the agility stolen with 
Essence Shift.
* Echo Stomp and Earth Splitter can hit Slark through his Shadow Dance ultimate.
* Slark's stats gain is relatively low compared to most agility carries making him quite squishy without his agility-based armor.
Marci
* Marci can destroy 
Supernova by herself with Unleash at any stage of the game.
* Phoenix is squishy hero with low armor and is very vulnerable for Rebound and Sidekick at the laning stage.
Elder Titan
* Viper is an agility hero, and his item build mostly includes agility items, so Natural Order can be devastating, removing all armor and greatly decreasing the effectiveness of 
Corrosive Skin, weakening Viper's magic resistance. Additionally, Echo Stomp and Earth Splitter deal both magical and physical damage, and can help bringing Viper down fast.
* Aghanim's Scepter may be necessary to take Viper down due to 
Nethertoxin's break.
Elder Titan
* 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.
Elder Titan
* Echo Stomp can impede Broodmother's ability to push towers due to its low cooldown and long sleep duration.
* Astral Spirit can provide Elder Titan large amounts of damage, armor, and movement speed from her spiderlings.
* Natural Order negates Broodmother and her spiderling's base armor and magic resistance, increasing most damage dealt to them.
Elder Titan
* Slow heroes that have a hard time escaping the Echo Stomp radius: 
Crystal Maiden, 
Pudge, 
Techies.
Elder Titan
* Heroes with AoE nukes will clear her illusions in no time, especially if they are percentage-damage-based, like Underlord's 
Firestorm, Elder Titan's Earth Splitter, 
Enigma's 
Midnight Pulse, 
Zeus's 
Arc Lightning, 
Jakiro's 
Liquid Frost from Aghanim's Shard etc.
Elder Titan
* Any hero who can counter-initiate in anticipation without getting caught in Reverse Polarity: 
Sven, 
Omniknight, Enigma, 
Luna, 
Naga Siren, 
Mars, Jakiro, 
Venomancer, Elder Titan, Faceless Void, Rubick, 
Keeper of the Light, 
Pugna, Invoker, 
Spectre, 
Alchemist, 
Treant Protector, 
Lina, 
Oracle, Zeus, Shadow Shaman, 
Phoenix, Razor, Huskar, 
Batrider, Kunkka, 
Tidehunter, 
Wraith King, 
Sand King, 
Medusa, 
Dawnbreaker.
Marci
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - 
Sniper, Drow Ranger, Lina, Rubick, etc.
Elder Titan
* In general, heroes with AoE or long range disables (such as Faceless Void with 
Chronosphere, Pudge with 
Meat Hook and Elder Titan with 
Echo Stomp) hinder Crystal Maiden, preventing her from using Freezing Field to help her team in a fight.
Marci
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, Lina, Rubick, etc.
Marci
* Marci can be effective against vulnerable squishy heroes that cannot deal with heroes that jump onto them - Sniper, Drow Ranger, Lina, Rubick, etc.
Elder Titan
* 
Untouchable makes her heavily reduce Elder Titan's physical damage output on her without Spell Immunity.
* 
Enchant can purge Astral Spirit's buff without Spell immunity.
* 
Nature's Attendants can protect her if she survives the full combo and manages to juke around.
Marci
* Untouchable doesn't work against Unleash, as Marci gains 1000+ attack speed for the fury combo.
* Enchantress' low health makes her a fragile target for Marci's damage blasts.
* Marci can use Rebound on one of her enchanted creeps to easily reach the Enchantress and negate the bonus damage dealt by her 
Impetus. It helps that most of her best creeps have a low attack range, creating a makeshift bridge towards their master.
Marci
* Heroes that reduce the damage that Marci can deal during her ultimate, like Razor, Rubick, Bane, Dragon Knight and Underlord.
Elder Titan
* Elder Titan's Natural Order completely nullifies Dragon Knight's high armor.

Counterspell will reflects from Dispose. Counterspell timing well can not throw from Dispose endured position and Dispose will blocked.
