* Skywrath Mage's long range and low cooldown magic damage spells can easily harass Timbersaw out of lane.
* Ancient Seal is not only a long lasting silence, (one of Timbersaw's biggest weaknesses) but it also makes him even more vulnerable to magical burst damage.
Additional:
* Magical burst damage is Timbersaw's weakness, and Ancient Seal not only amplifies it but also prevents him from using Timber Chain to escape for up to 6 seconds.
* He generally doesn't build early items to deal with silences.
* Reactive Armor does not trigger on magic damage or spells, meaning that even a Pipe of Insight won't give him the massive sustain he normally gets from attacks.

* Searing Chains prevents usage of Timber Chain.
* Timbersaw is vulnerable to magical burst damage, which Ember Spirit provides with Fire Remnant and Flame Guard.
* Timbersaw's abilities deal pure damage, thus they cannot remove Flame Guard.

* Skywrath Mage can easily harass Alchemist in the laning phase with multiple Arcane Bolts. Additionally, if Alchemist is in the process of throwing an Unstable Concoction, and has no way to dispel Ancient Seal, the self stun becomes an easy set up for Mystic Flare.
* Caution, however, as a decently farmed Alchemist with {Item ID:Radiance} and {Item ID:Manta Style} can easily send illusions to harass and force Skywrath Mage out.

* Ember's magic damage build is able to burst down Alchemist due to his low strength gain and Alchemist's normal item pick up.

* Ancient Seal can silence Jakiro up to 6 seconds. Also, it makes Jakiro vulnerable to magical spells.
* Skywrath Mage can burst down Jakiro with his high damage magical spells.

* Heroes with good mobility to avoid Jakiro's abilities and with good chase to punish Jakiro from pushing a tower: Bloodseeker, Ember Spirit, Juggernaut, Phantom Assassin, Weaver.

* 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.

* The high mobility provided by Fire Remnant makes it hard for Windranger to find a good position to land Shackleshot or a full duration of Focus Fire.
* Flame Guard deals considerable magical damage to Windranger.

* Skywrath Mage's Mystic Flare can deal huge damage to Clockwerk inside his Power Cogs.

* Ember Spirit's Fire Remnant is an easy way to escape from Clockwerk's Power Cogs.
* Flame Guard blocks most of the magical damage Clockwerk does.

* Sleight of Fist with Battle Fury deals a lot of damage to Nature's Prophet's team if they stand close to his Treants, as well as killing all of his Treants and getting lots of gold.
* Ember Spirit with Fire Remnant and Boots of Travel can teleport and defend tower whenever Nature's Prophet tries to push.
Additional:
* Ember Spirit can easily deal with Nature's Call by using his Flame Guard and with Battle Fury. He also has multiple ways of escaping Sprout. Additionally, Ember Spirit can break Sprout's trees with Activate Fire Remnant and interrupt Teleportation with Searing Chains.

* Disruption is not reliable enough to catch an Ember Spirit with a backup Fire Remnant.
* Sleight of Fist will make quick work of the spawned illusions.
* Ember Spirit usually builds Eul's Scepter of Divinity to dispel Shadow Poison and Soul Catcher and Linken's Sphere to block Disruption and Demonic Purge.
* The best you can do against an Ember Spirit is to dispel his Flame Guard with your Demonic Purge.

* 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.

* Arcane Bolt's low cooldown allows him to deal consistent damage to Morphling, and is a viable way to disable Linken's Sphere.
* Ancient Seal prevents Morphling from using any of his skills, giving Skywrath Mage and his team ample time to burst Morphling down.
* Mystic Flare coupled with a stun/root can easily burst Morphling down, especially if he has more stats shifted to Agility.
* Alternatively, Morphling can use Morph to use Skywrath Mage's own silence and nukes against him.

* Ember Spirit can deal devastating damage to illusion heroes like Terrorblade with Sleight of Fist. Terrorblade also has no way of preventing Ember Spirit from getting Activate Fire Remnant off. Additionally, Ember Spirit's ability to fight from long range as well as his wide skill set won't give many opportunities for Terrorblade to get Sunder off.
Additional:
* Ember Spirit can deal devastating damage to Terrorblade and his illusions with Sleight of Fist.
* Terrorblade has no disable to lock down Ember Spirit and prevent him from escaping with Fire Remnant. In addition, he doesn't like purchasing disabling items, which are the only solutions to deal with Ember Spirit.

* Ancient Seal's instant cast time will often silence Brewmaster before he can do anything.
* Brewmaster also has no defense against Skywrath Mage's massive magical damage.

* Cold Embrace is a perfect setup for Mystic Flare.
* Winter Wyvern is a spellcaster, and the 6 second silence from Ancient Seal can prevent her from contributing much.
* Because Skywrath Mage tends to stay back in fights, Winter Wyvern will have to get close to a teamfight to cast Winter's Curse on him. However, if she chooses to cast it on one of his allies, his low attack speed and damage means that he won't do much.
Additional:
* Cold Embrace is the perfect setup for Mystic Flare, and his 6-second silence is good against Winter Wyvern in general.

* Arcane Bolt allows Skywrath Mage to harass Earthshaker out of lane.
* Ancient Seal is an instant silence that can be pre-cast onto Earthshaker to disrupt his combo, before he uses Blink Dagger to initiate.
* Mystic Flare will nuke Earthshaker down while he stands in place during his long cast animations.

* Mystic Flare can easily burst down Legion Commander while she is Dueling.

* Ember Spirit has much higher mobility in Fire Remnant than Void Spirit.
* Ember's Flame Guard is effective against Void Spirit's spells, as most of them deal magical damage.
* The root from Searing Chains prevents Void Spirit from using Dissimilate or Astral Step.

* Searing Chains can stop Charge of Darkness if timed correctly.
* Activate Fire Remnant can be used to escape an approaching Spirit Breaker, or lead Spirit Breaker into a bad situation.
* Activate Fire Remnant and Sleight of Fist allows Ember Spirit to dodge Charge of Darkness if timed correctly.

* Crystal Maiden is extremely fragile and she's an easy target for him. She has no real disables that can lock Ember Spirit down, and all of her skill damage can be negated with Flame Guard. The damage from Searing Chains, Flame Guard, and Sleigh of Fist can easily take her down.

* Flame Guard blocks Dark Willow's magical burst damage, and harms her if she tries to get close to attack with Bedlam.
* Sleight of Fist and Fire Remnant makes it hard for Dark Willow to fully disable Ember Spirit.

* A pre-placed Fire Remnant allows Ember Spirit to escape Upheaval.
* Flame Guard blocks Shadow Word's damage.
* Sleight of Fist allows Ember Spirit to attack from range, ignoring Upheaval, and Searing Chains lets him interrupt it.

* Fire Remnant allows Ember Spirit to escape while Ruptured.

* Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.

* Sleight of Fist keeps Ember Spirit invulnerable until he hits every unit in its area of effect allowing him to stall for large amounts of time against Broodmother and her large amounts of spiderlings, or potentially damaging them enough if equipped with an item to improve wave clearing such as Battle Fury or Maelstrom to prevent her pushes entirely.
* Flame Guard will damage any of Broodmother's spiders in an area, deterring her from attempting to kill him. It can also be used during Sleight of Fist to amplify damage done.
* Fire Remnant allows Ember Spirit an escape from Broodmother that is unaffected by her Incapacitating Bite.

* Heroes with powerful spammable abilities will prove problematic for Grimstroke as Ink Swell does not protect him from them: Zeus, Skywrath Mage, Tinker, Lina

* Heroes with high mobility will be able to avoid Gyrocopter's area attacks: Storm Spirit, Morphling, Ember Spirit

* Heroes with a high degree of mobility and invisibility are hard to catch with Meat Hook: Ember Spirit, Riki, Clinkz, Queen of Pain.

* Heroes with considerable mobility can easily escape from a rolling Pangolier: Anti-Mage, Queen of Pain, Void Spirit, Storm Spirit, Ember Spirit, Earth Spirit, moreover, if a player is familiar with how Rolling Thunder work, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.

* Cleave heroes will clear her illusions. Such heroes include Sven, Magnus, Dragon Knight in Elder Dragon Form, Ember Spirit (via item), Phantom Assassin (via talent or item), etc.

* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Heroes that can dodge Glimpse:
* Puck with Phase Shift
* Riki with Tricks of the Trade
* Phantom Lancer with Doppelganger
* Ember Spirit with Sleight of Fist and Activate Fire Remnant
* Chaos Knight with Phantasm
* Naga Siren with Mirror Image
* Tusk with Snowball
* Juggernaut with Omnislash
* Brewmaster with Primal Split
* Lifestealer with Infest
* Phoenix with Supernova

* Heroes with high magical or pure damage will bypass Bulwark: Timbersaw, Dark Willow, Enigma, Invoker, Pugna, Skywrath Mage, Tinker, Zeus, Oracle.

* Heroes who can dodge Earth Spirit's abilities: Ember Spirit, Puck, Weaver

* 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.

* Silence (and mana burns) will be a persistent problem for Phoenix, as it is heavily reliant on its abilities whether defensively or offensively, so heroes like Death Prophet, Skywrath Mage, and even Nyx Assassin must be closely observed to prevent being shut down by these heroes.
* Hexes are a greater threat to Phoenix as they also disable items, preventing Phoenix from dispelling the debuff on its own.

* Any hero with teleport abilities (e.g. Ember Spirit, Storm Spirit) can easily break Static Link.

* Even though Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, Queen of Pain, Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.

Additional:
* Arcane Bolt has a long range and a low cooldown, and is a great spell to waste Linken's Sphere. It also serves as an effective spell to harass Weaver with.
* Ancient Seal prevents Weaver from using Shukuchi or Time Lapse.

* Any heroes with stuns or silences: Death Prophet, Lion, Shadow Shaman, Skywrath Mage

Additional:
* Similar to Timbersaw, Storm Spirit builds items that don't help against silences.
* An Orchid Malevolence will most likely silence you first. However, if you grab a Eul's Scepter of Divinity, you might dispel his silence and turn the tides to your favor.
* Root and silence are Storm Spirit's ultimate counters. Skywrath Mage has a silence in his kit, and has Rod of Atos as his core item. If he dispels one, you cast the other, both leaving him vulnerable.
* If he builds Black King Bar, he spends 4050 gold that doesn't help him snowball effectively.

* Flame Guard absorbs up to 500 magical damage (700 with Level 10 talents), which helps Ember Spirit survive and react to Storm Spirit's high magical damage.
* Searing Chains can root enemies up to 3 seconds, making Storm Spirit unable to escape with Ball Lightning.
* Fire Remnant deals high magical damage when casting multiple instances at once, granting Ember Spirit the damage to burst Storm Spirit down in the early to mid game.

* Heroes with long range abilities are also able to touch Zeus, such as Clockwerk, Kunkka, Puck, Skywrath Mage, Spirit Breaker, Tusk and others.

* Strong nuking supports like Skywrath Mage. Vengeful Spirit has subpar attack range, making it harder for her to harass and last hit safely. With enough pressure she can be bullied out of a lane.

Additional:
* Skywrath Mage should have the upper hand against Vengeful Spirit with Ancient Seal.
* Vengeful is highly dependant on her abilities and has no natural means to deal against silences.
* Her low attack range allows Skywrath Mage to easily bully her out of the lane.

* Sleight of Fist, allows Ember Spirit to destroy all of Phantom Lancer's illusions.
* Flame Guard also deals significant damage to illusions, and protects against Spirit Lance.
* Phantom Rush is unable to catch Ember Spirit when he teleports to his Fire Remnants.
Additional:
* Sleight of Fist is the natural counter to Phantom Lancer's army of illusions, especially when combined with Battle Fury.

* Arcane Bolt's long range and low cooldowns allows Skywrath Mage to severely harass Phantom Assassin in lane.
* Ancient Seal prevents Phantom Assassin from escaping or engaging with Phantom Strike.
* Mystic Flare's heavy magical damage nukes Phantom Assassin down quickly during the early to mid game.

* Ember Spirit is evasive and can dodge close encounters with melee heroes like Chaos Knight. Ember Spirit can't be caught with the slow from Reality Rift, and Flame Guard and Sleight of Fist can bring Phantasm's illusions down quickly.

* Even though Linken's Sphere will block your silence, you can cast Arcane Bolt to break it or wait until someone on your team breaks it. In addition, Linken's Sphere builders are usually squishy targets vulnerable to silences: Weaver, Queen of Pain, Morphling, Clinkz, etc. Don't forget that Ancient Seal also increases the magical damage these enemies take, along with silencing them.

Additional:
* A good Skywrath Mage with quick fingers will punish Queen of Pain for blinking aggressively. Ancient Seal is a six second silence with no cast time, so he can interrupt either her Shadow Strike or Sonic Wave, and a good Mystic Flare on top of that will seal the deal for her.
* Ancient Seal also has pretty good range so he could get it off before she blinks away.

* Heroes that heavily depend on illusions or summons, (Naga Siren, Terrorblade, Phantom Lancer, Lycan,...) are vulnerable to Sleight of Fist and even more so if Ember Spirit has Battle Fury.

* Heroes with escaping and disjointing abilities can be good against Juggernaut: Riki, Queen of Pain, Puck, Storm Spirit, Ember Spirit, Slark etc.
