* Grave Chill will make Crystal Maiden's bad movement speed even worse.
* Soul Assumption charges can easily be stacked up from Freezing Field, allowing Visage to nuke enemies multiple times throughout the fight.
* {U:Familiar}'s Stone Form can also be used to interrupt Freezing Field, even while Crystal Maiden is under the effects of Glimmer Cape. Crystal Maiden must purchase a Black King Bar, which is far more costly.

* Stone Form's long stun duration may prevent Puck from using escape abilities.
* Visage frequently builds Rod of Atos for the root that will make Puck unable to move and use his escape abilities. Alternatively, Visage can also build Bloodthorn to prevent Puck from using his escape abilities and make him more vulnerable to damage.

* Crystal Maiden has a very bad movement speed, so Impale is easy to land against her. Furthermore, even while trapped by Frostbite, Nyx Assassin can still cast Impale.
* Crystal Maiden has very low armor, so Vendetta is very effective.
* Nyx Assassin has two ways to stop Freezing Field, provided she doesn't get a Black King Bar. He can either pop Spiked Carapace and simply walk into the field, or he can use Impale to interrupt the field, since Crystal Maiden has to channel it.
Additional:
* Spiked Carapace easily interrupts Freezing Field.
* Frostbite's damage over time sets up an easy Spiked Carapace stun.
* Crystal Maiden is extremely fragile and dies quickly to Nyx Assassin's burst damage.

* Illusory Orb is easy to reflect with Spiked Carapace, either stunning Puck and setting up an easy Impale or forcing a premature Phase Shift.
* Puck is an intelligence hero that tends to build intelligence items, making it vulnerable to Mana Burn.
* An ill-timed Phase Shift can easily set Puck up to be stunned by Impale.
* Puck's low base armor and below average agility gain mean it is always susceptible to Vendetta.
Additional:
* Nyx Assassin can take advantage of every one of Puck's weaknesses. His entire skill set is very effective in countering Puck.
* Because Illusory Orb is such a slow moving projectile, Nyx Assassin can simply walk into the orb and activate Spiked Carapace, stunning Puck and setting up an easy Impale. This can be circumvented by using Phase Shift while the orb is traveling, however, that means that Puck cannot use Phase Shift to dodge any other skill nor use it to safely blink away from a fight.
* Puck is an intelligence hero that likes to build intelligence items such as Eul's Scepter of Divinity, Scythe of Vyse, and Dagon. This makes Mind Flare that much more deadly against Puck.
* An ill-timed Phase Shift can turn into an easy setup for Impale.

* Ice Path allows Jakiro to easily cancel Freezing Field.
* Freezing Field makes Crystal Maiden an easy target for all of his abilities without a Black King Bar.
* With the Aghanim's Scepter upgraded Macropyre, Black King Bar becomes nearly useless for Crystal Maiden, as its high pure damage over time, long duration and ability to pierce spell immunity will either force Crystal Maiden to forcefully cancel Freezing Field or even discourage her from using it at all.
Additional:
* Ice Path allows Jakiro to easily cancel Freezing Field.
* Freezing Field makes Crystal Maiden an easy target for all of Jakiro's abilities without a Black King Bar.
* Aghanim's Scepter upgraded Macropyre can deal pure damage-over-time and pierce spell immunity, making Black King Bar nearly useless for Crystal Maiden, as its high damage over time and long duration can discourage Crystal Maiden to use Freezing Field. Remember, however, that Crystal Maiden can partially solve this issue by buying Aghanim's Shard, which will allow her to simply walk out of Macropyre.

* Jakiro has 3 damage over time spells, 2 of which are from debuffs on Puck (Dual Breath and Liquid Fire) and 1 affecting an entire area (Macropyre), making it easy for him to disable the Blink Dagger.
* Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.
Additional:
* Jakiro has 3 damage over time spells, 3 of which are from debuffs on Puck: Dual Breath, Liquid Fire and Liquid Frost from Aghanim's Shard from and 1 affecting an entire area (Macropyre), making it easy for him to disable the blink dagger.
* Ice Path is also strong against Puck, as he can cast it towards Puck during Phase Shift, who then gets instantly stunned once Phase Shift ends.

* Crystal Maiden is squishy, is heavily spell reliant, has low base Intelligence, and is naturally slow, making her an ideal target for Silencer.
* Crystal Maiden's Freezing Field has a similar cooldown to Global Silence, therefore, Freezing Field can almost always be canceled to ruin aggressive Crystal Maiden initiations.

* Generally strong against lots of spellcaster-themed heroes, Puck fully relies on its skill set and cannot do almost anything when silenced.
* Arcane Curse disables Blink Dagger for quite some time, and is also effective against Puck as it tends to use its spells a lot.
* Glaives of Wisdom can do a lot of damage against Puck due to Puck's low agility gain and armor.
* Last Word can prevent Puck from getting a full combo off, limiting its effectiveness in team fights or ganks.
* Global Silence can take Puck out of fights entirely because of its long-duration silence.

* Crystal Nova helps on farming while applies an area slow.
* Frostbite extends Rubick's lockdown duration while providing extra damage, also serves as a farming ability.
* Freezing Field deals much greater damage thanks to Arcane Supremacy in teamfights.
* Freezing Field is a channeling ability and therefore can be stolen easily.
* Crystal Maiden has no innate ability to interrupt Freezing Field, though it may not be the case for her teammates; Yet a well-times Telekinesis lift or drop can interrupt Freezing Field.
* Consider build items that strengthens Freezing Field, such as Aghanim's Shard, Black King Bar and Aghanim's Scepter to reach its full potential.

* All of Puck's abilities are good for Rubick to Spell Steal:
* Illusory Orb and Waning Rift are all great wave-clear abilities.
* If Rubick manages to steal Waning Rift, he can silence Puck, disabling all its abilities including Phase Shift, Puck's main survivability tool.
* Dream Coil is a powerful teamfight ultimate that leashes enemies and disables their movement.
* As an elusive hero who requires constant repositioning, Puck is greatly countered by its own ultimate as it disables all its mobile abilities and items (especially Blink Dagger), forcing it to either stay in the danger zone or latches and stuns for a long time.
* Although Phase Shift does not provide extra damage or lockdown on its own, it does grant Rubick invulnerability, and enables him to use Blink Dagger with full duration similar to Puck's escaping combos.
* Rubick can initiate on Puck relatively fast as Telekinesis only has a 0.15 second cast animation.

* Rubick can initiate on Puck relatively fast as Telekinesis only has a 0.15 second cast animation.

* Doom alone can easily pick off Crystal Maiden since she is fairly fragile, even with using only basic attacks, Infernal Blade, and Scorched Earth.
* Doom prevents her from using any abilities in a fight, making her impact negligible.
* Devour allows Doom to acquire a stun, allowing him to cancel Freezing Field without having to use Doom.

* Doom is generally tanky and has naturally high health, allowing him to survive Puck's onslaught in any stage of the game.
* His namesake ultimate Doom is one of the best solutions to counter Puck, as it will silence Puck for a lengthy duration. A Puck silenced for more than 3 seconds usually ends up dead.
* In addition, if Doom chooses the Level 25 talent Doom applies Mute, Puck will not be able to use items altogether, most especially Blink Dagger and Eul's Scepter of Divinity, making Doom a nightmare to deal with as Puck.

* Heroes with low mobility that rely on spells: Zeus, Lina, Crystal Maiden.

* Puck cannot use any of its normal means to survive should Night Stalker catch it within Crippling Fear, and goes down quickly.
Additional:
* Void is a potent nuke that is devastating to Puck's low health pool.
* Crippling Fear silence can prevent Puck from casting spells, leaving it vulnerable.

* Lone Druid's early game is good against slow, squishy supports since his bear is very strong early game and an Entangling Claws proc almost always guarantees a kill: Ancient Apparition, Crystal Maiden, Shadow Shaman, etc.

* Lone Druid has a huge reserve of health on the Summon Spirit Bear and a quick regeneration of his health with the help of Spirit Link, which makes the Puck's magical abilities useless, since they cannot break through such a large pool of health
* The ability of the Summon Spirit Bear and in the True Form of the Lone Druid Entangling Claws allows you to catch Puck when he released the Illusory Orb, since Puck will not be able to apply Ethereal Jaunt during the root action
Additional:

* The slow from Torrent makes Crystal Maiden's already bad movement speed even worse.
* Kunkka has many tools to interrupt Freezing Field (most notably Torrent, Ghostship and Torrent Storm from Aghanim's Scepter), as she is an easy target while channeling it.
* It is worth noting that most of Kunkka's abilities do not pierce through spell immunity, so purchasing a Black King Bar might help Crystal Maiden in this regard.

* Heroes who are strong against mobile heroes: Disruptor, Bloodseeker, Kunkka, Keeper of the Light.

* Heroes who can easily harass Crystal Maiden out of lane in the early game (Clinkz, Viper) can prevent Crystal Maiden from being able to level effectively, and can ultimately slow down her level 6, 12, and 18 to a point where enemy carries already have items to address her ultimate.

* Viper wins on the central line of Puck, because he has a huge damage from the Poison Attack ability, which Puck is not able to constantly avoid using Phase Shift, which will give Viper an advantage in the possible damage inflicted on each other
* Puck takes more damage than it does due to the passive Corrosive Skin ability of the Viper, which makes it unprofitable for the Puck to fight against the Viper at an early stage of the game, when the Puck has a very small pool of health.

* Even with Black King Bar or Linken's Sphere, Pudge's Meat Hook can still cancel Crystal Maiden's Freezing Field as she is a very easy target while channeling it.
* Pudge's Rot can make Crystal Maiden's already bad movement speed even worse.
* Many stacks of Flesh Heap will make it nearly impossible for Crystal Maiden to kill Pudge.
* Pudge's Dismember can also be used to cancel Crystal Maiden's Freezing Field, and alternatively, Pudge can also use it to save allies from getting killed by Crystal Maiden and heal them when upgraded with Aghanim's Shard.
* Crystal Maiden is prone to ganks in the lane or in the off-lane without proper vision. Pudge can take advantage of Crystal Maiden's lack of mobility, and gank her often.
Additional:
* Meat Hook can cancel Freezing Field, even if Crystal Maiden has Glimmer Cape.
* She is also slow and fragile, making her a good target for ganking.

* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* 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.

* Puck cannot use spells if affected by Time Dilation, especially Phase Shift for main survivability as it effectively triples its cooldown.
* Chronosphere can end Puck's life quickly, as stun, more than 3 seconds will be a death sentence to Puck.
* If not silenced, Faceless Void can just Time Walk to undo Puck's Burst damage.
Additional:
* Hard lockdowns such as Chronosphere can be used to quickly take down Puck. Whenever Puck is disabled for longer than 3 seconds, he will usually end up dead.
* As the type of hero that spams spells, Time Dilation counters Puck very effectively. Phase Shift is Puck's main ability for survivability, and Time Dilation effectively triples its cooldown.
* If not silenced, Faceless Void can use Time Walk can easily undo the damage dealt by Illusory Orb, Dream Coil and Dagon.

* Viscous Nasal Goo can hinder Crystal Maiden's already abysmal mobility, which allows Bristleback (or his teammates) to run her down and kill her.
* Bristleback frequently builds Blade Mail, which can quickly kill Crystal Maiden if her ultimate is used while he is under its effect.
* The passive part of Bristleback will trigger many, many times under the damage from Freezing Field, and as the stacks increase, the damage output from each successive cast (or proc) will eat away at Crystal Maiden's small HP pool.

* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* Snowball allows Tusk to easily cancel Freezing Field from a safe distance without putting himself in any danger.
* Walrus PUNCH! is most certainly a high enough damage nuke to easily kill off Crystal Maiden.
* Ice Shards can prevent the already immobile Crystal Maiden from escaping, making her an easy kill for either Tusk or a teammate.
Additional:
* Crystal Maiden's low health and armor make her an easy target for Walrus PUNCH!
* Tusk's Snowball can protect allies and cancel Freezing Field.
* Snowball and Walrus PUNCH! can interrupt Freezing Field.

* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.

* Vulnerable spellcasters with no escape mechanisms are easy targets for Huskar: Lich, Crystal Maiden, Silencer, Keeper of the Light, Venomancer, etc.

* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* Phase Shift is not an advantage against Arc Warden at all because Arc Warden can turn Puck's Phase Shift ability against him by using Spark Wraith, ensuring it to hit. To make this worse, Arc Warden can do it twice with his Tempest Double.
* Flux is also an instant spell (and therefore unavoidable) with a heavy slow and damage over time, which disables Blink Dagger for a certain period of time.

* Berserker's Call can interrupt Freezing Field, even through Black King Bar and/or Glimmer Cape.
* Battle Hunger makes Crystal Maiden's already bad movement speed even worse.
* Axe frequently builds Blade Mail, which can quickly kill Crystal Maiden if her ultimate is used while he is under its effect.

* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* Waning Rift's silence is almost completely worthless against Wraith King, due to him having only 1 active ability.
* Wraith King's only active ability, Wraithfire Blast, is strong against Puck if it hits, because it applies a damage over time on top of stunning and doing impact damage, disabling Puck for a while, and Blink Dagger for even longer. It is very important to avoid getting hit by this spell when playing against Wraith King.
* Even if Puck succeeds to burst down Wraith King, Reincarnation will ensure that Wraith King can fight back against him while leaving Puck exhausted and nearly unable to defend itself against Wraith King. And to make things worse, Puck is not a common Diffusal Blade nor Disperser wielder to counter this problem at all.

* Duel is a great initiation to target Crystal Maiden with, as it prevents her from using Freezing Field or any other abilities and allowing the enemy team to quickly kill her before she can aid her team in a fight.

* Crystal Maiden will be not able to cast her Freezing Field while being constantly stunned by Enigma's Malefice.
* Enigma's Black Hole can cancel Freezing Field's channeling regardless of her Glimmer Cape and Black King Bar.

* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; Spirit Breaker, Legion Commander, Axe, Puck, and Slardar.

* Battery Assault, Power Cogs, and Hookshot can interrupt Freezing Field, the latter two being able to go through invisibility should Crystal Maiden use Glimmer Cape.
* Rocket Flare can be used to find Crystal Maiden should she try to hide in the trees to try to safely cast Freezing Field.
* Hookshot allows Clockwerk to easily close in on Crystal Maiden and kill her.

* Boulder Smash and Geomagnetic Grip allow Earth Spirit to easily disrupt Freezing Field, regardless of where Crystal Maiden is due to their incredible range. Earth Spirit is quite possibly the best hero for stopping long channeling abilities, and Crystal Maiden is vulnerable to him without a Black King Bar.
* All of Earth Spirit's spells allow him to easily close in on Crystal Maiden and kill her. Since she is a low health support, she generally stays behind in teamfights, but Earth Spirit can easily close the distance.
* Crystal Maiden has low movement speed and no other escape mechanism, rendering her extremely vulnerable to Earth Spirit's arsenal of long-range, damaging spells.

* Earth Spirit Eliminates the possibility of the Puck to hide in Phase Shift and avoid an attack by Geomagnetic Grip with its AOE-silence, which is why it can help the team kill him
* Puck can't throw off the effect of Magnetize any of his abilities, which is why he will constantly receive damage if Earth Spirit extends this ability with his Stone Remnant
Additional:
* Earth Spirit eliminates the possibility of Puck to hide with Phase Shift and avoid an attack by Geomagnetic Grip with its AoE silence, which is why it can help the team kill it.
* Puck can't throw off the effects of Magnetize with any of its abilities, making it constantly receive damage if Earth Spirit extends this ability with his Stone Remnant.

* Cold feet can be used to ensure that the full channel of Freezing Field doesn't go off.

* Gush can make Crystal Maiden's already weak armor even weaker.
* Kraken Shell can dispel Frostbite, preventing him from getting stuck inside Freezing Field.
* Ravage is very useful for interrupting Freezing Field, even while Crystal Maiden is under the effects of Glimmer Cape. Crystal Maiden must purchase a Black King Bar, which is far more costly.

* Smoke Screen effectively disables Crystal Maiden's channeling spell: Freezing Field.
* Due to her low health and armor throughout the game, Riki can kill her easily.

* Riki and Disruptor: Smoke Screen and Static Storm, respectively, can be thrown wherever Puck used Phase Shift, making Puck an easy target if it doesn't have Blink Dagger or is on cooldown. Puck is also very susceptible to Riki's high attack damage when attacking from the back. Glimpse also prevents Puck from escaping altogether.

* Lucent Beam allows Luna to easily cancel Freezing Field.
* Without Black King Bar protection, Lucent Beam and Eclipse can make a short work out of Crystal Maiden's abysmal health.
* Skilled Luna will always buy Dust of Appearance, allowing her team to have a vision on Crystal Maiden while invisible and during channeling Freezing Field.
* Even with Black King Bar, Luna can still inflict considerable damage on Crystal Maiden with her attacks, which get empowered with Moon Glaives and Lunar Blessing, also smart and skilled Luna will buy Abyssal Blade to cancel Freezing Field even through Black King Bar in case of emergency. And since Crystal Maiden rarely buys Linken's Sphere, this can be a very big problem for her.
Additional:
* Lucent Beam allows Luna to easily cancel Freezing Field.
* Without Black King Bar protection, Lucent Beam and Eclipse can make a short work out of Crystal Maiden's abysmal health.
* Skilled Luna will always buy Dust of Appearance, allowing her team to have a vision on Crystal Maiden while invisible and during channeling Freezing Field.
* Even with Black King Bar, Luna can still inflict considerable damage on Crystal Maiden with her attacks, which get empowered with Moon Glaives and Lunar Blessing, also smart and skilled Luna will buy Abyssal Blade to cancel Freezing Field even through Black King Bar in case of emergency. Forcing Crystal Maiden to buy Linken's Sphere.

* Mirror Image can dispel Frostbite. A similar effect can be achieved with Manta Style, a core item on Naga Siren.
* Song of the Siren can stop Freezing Field regardless of any kind of invisibility as well as allow Naga Siren's team to quickly close the gap on Crystal Maiden.
* With Aghanim's Scepter, Naga Siren can get access to Reel In ability, which can allow her to pull Crystal Maiden toward herself and her team and cancel Freezing Field even through Black King Bar.
Additional:
* Mirror Image can dispel Frostbite.
* Song of the Siren can stop Freezing Field regardless of any kind of invisibility as well as allow Naga Siren's team to quickly close the gap on Crystal Maiden.
* Ensnare allows Naga Siren and her team to quickly catch up with Crystal Maiden and kill her.
* With Aghanim's Scepter, Naga Siren can get access to Reel In ability , which can allow her to pull Crystal Maiden toward herself and her team and cancel Freezing Field even through Black King Bar.

* Unless Puck is facing the direction he wants to blink while in Phase Shift, the Venomous Gale and Noxious Plague combo consistently ticks many times over several seconds, making it very difficult to use Blink Dagger towards the other direction. Puck's slow turning rate makes this even worse.
* Venomancer can use Plague Wards to reveal Puck's position before he even gets a chance to initiate.

* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.

* Heroes with little health or magic resistance are easily picked off with Oracle's magic burst, such as Skywrath Mage, Crystal Maiden, or Enchantress.

* 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.

* Heroes with strong channeling spells like Crystal Maiden's Freezing Field, Bane's Fiend's Grip, and Enigma's Black Hole can easily be interrupted from a long range by Nether Swap, assuming they don't have a Linken's Sphere.

* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.

Additional:
* Crystal Maiden is an ideal target for Lifestealer due to her poor mobility and low health pool. Lifestealer can usually catch up to her simply by casting Rage, as none of her abilities pierce through magic immunity. Freezing Field can potentially make her even more vulnerable to Lifestealer while under Rage as she is even more immobile while channeling it.
* Lifestealer commonly buys Abyssal Blade, which allows him to cancel Freezing Field, even if Crystal Maiden is spell immune.
* Alternatively, Aghanim's Scepter upgraded Infest combined with Abyssal Blade and with items that provide attack speed which Lifestealer commonly buys allow him to to cancel Freezing Field from within the Crystal Maiden.

* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.

* Generally, any fragile heroes will have a hard time dealing with Undying's tankiness, and even more so if Decay is used on them. Some examples are Crystal Maiden and Witch Doctor.

* Heroes that depend on disrupting fights with ability combos or big ultimate abilities are vulnerable to the long stun of Fiend's Grip: Disruptor, Death Prophet, Enigma, Faceless Void, Invoker, Lich, Magnus, Mars, Medusa, Outworld Destroyer, Phoenix, Puck, Queen of Pain, Shadow Fiend, Treant Protector, Underlord, Winter Wyvern, Witch Doctor, Zeus.

* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* Juggernaut and Lifestealer have abilities (Blade Fury and Rage respectively) that prevent Crystal Maiden from using her spells on them in the early game, before Black King Bar and other magical reduction is even an issue.

* Heroes with spell immunity or pseudo-blinks which provide invulnerability: Lifestealer, Juggernaut, Omniknight, Huskar, and Tusk have spells which allow them to easily escape Dream Coil.

* Heroes with low health are especially vulnerable to Marksmanship's high damage output: Clinkz, Crystal Maiden.

* Any hero with low mobility and max healthsuch as Silencer, Crystal Maiden etc.

* Heroes that have small health pools and little to no escape mechanisms are even easier prey for Necrophos. Ghost Shroud's slow will allow him to catch him with them, and get nuked down with his abilities, even preventing retaliation due to Reaper's Scythe's stun. Such heroes include Crystal Maiden, Witch Doctor, Warlock or Shadow Fiend.

* Crystal Maiden's already low armor and easily interruptible ultimate, Freezing Field can make Slardar her worst nightmare. Crystal Maiden also often builds Glimmer Cape which is revealed by Corrosive Haze.

* 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.

* A Lycan with Shapeshift can always run down Puck for a very quick kill due to its low armor. It is important to abuse as many cliffs and trees as possible to escape from a Lycan.

* As Crystal Maiden is squishy with very bad movement speed, Spectre can easily stay on Crystal Maiden with Haunt and Spectral Dagger.
* Late game, with enough farm, Spectre can withstand an entire Freezing Field, possibly even causing Crystal Maiden to kill herself from Dispersion.

* 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.

* Backline supports (Lion,Crystal Maiden) can keep Puck pinned long enough for a kill.

* Heroes with blink or movement abilities, which are disabled by Pounce's leash: Anti-Mage, Earth Spirit, Faceless Void, Magnus, Mirana, Monkey King, Morphling, Pangolier, Phantom Assassin, Phoenix, Puck, Queen of Pain, Riki, Sand King, Spirit Breaker, Timbersaw, Tusk.

* Heroes who rely on channeling abilities can be interrupted in teamfights by Rolling Thunder: Crystal Maiden, Pugna, Witch Doctor

* Innately fragile heroes will die almost instantly to Reality Rift while Chaos Knight has illusions active: Drow Ranger, Bane, Necrophos, Crystal Maiden.

* Heroes with large health pools (Pudge) or good innate magic resistance (Anti-Mage) can be very problematic for Crystal Maiden, since even if they are under the effect of her ultimate for the entire duration, the damage output is simply not enough to kill or force them to retreat.

* Crystal Maiden's low health pool and slow movement speed make her a tempting and easy target.
* However, it may be wise to build Black King Bar first before attempting to fight her alone, as she can disable you and retaliate with Freezing Field.

* Heroes who are strong against mobile heroes: Disruptor, Bloodseeker, Kunkka, Keeper of the Light.

* Heroes with a low health pool (Crystal Maiden, Skywrath Mage etc)

* Once you farm up an Orchid Malevolence or a Scythe of Vyse, you're suddenly a lot more fearsome to elusive heroes like Storm Spirit or even that pesky Puck.

* Heroes with channeled abilities which Assassinate may cancel at long range: Witch Doctor, Crystal Maiden, Shadow Shaman, Pugna

* Heroes with a low attack speed or are fragile will find themselves unable to deal with Troll Warlord's high physical damage and attack speed, like Crystal Maiden or Sven.

* Heroes with slow movement speeds and small health pools (supports like Crystal Maiden or Witch Doctor) are easy targets for Phoenix. Should they be inflicted by its DOT debuffs, they will be very quickly killed without even getting a chance to fight back.

* Heroes with channeled abilities can be interrupted by a long-range Fissure: Crystal Maiden, Witch Doctor, Bane, Pugna, Pudge.

* Sacred Arrow can be used to interrupt Freezing Field from a safe distance, forcing her to cancel it to dodge or get hit.
* Crystal Maiden has very slow movement speed, making her an easy Sacred Arrow target.
* Crystal Maiden has low health and can easily be killed with an Aghanim's Scepter combo or just when hit with an arrow.
* If Frostbite has already been used, Mirana can Leap away even when slowed by Crystal Nova or Freezing Field.

* Fragile supports with low armor are always a good prey, also her Psionic Trap will wear down most attempts to flee with their built-in disables: Silencer, Crystal Maiden, Warlock, Ancient Apparition, Grimstroke, Witch Doctor

* None of Puck's abilities have any damage-over-time components, meaning that Refraction is a valuable form of defense against Puck's lane harassment.
* Psi Blades deals pure damage and spills over instantly. Puck cannot reliably dodge the damage with Phase Shift.
Additional:
* Puck high magical burst is almost completely useless against Refraction. Templar Assassin often buys Orchid Malevolence to render Puck useless in teamfights.

* Phantom's Embrace can silence Crystal Maiden and disrupt Freezing Field's channeling. Her slow movement speed and fragile nature will also make her an easy target for Stroke of Fate and Ink Swell.

* Axe, Bristleback, Centaur Warrunner, Spirit Breaker, Pudge, Huskar, Wraith King, Doom: These heroes are too tanky for Puck to burst down. Also, all of them have spells which can deal with and shut Puck down reliably.

* Heroes who are strong against mobile heroes: Disruptor, Bloodseeker, Kunkka, Keeper of the Light.

* In the same vein, heroes with silences — especially with the AoE ones like Death Prophet's Silence — can also prevent Crystal Maiden from being able to impact a fight.

* Channeling heroes will not go well against Warlock, especially those who build Black King Bar as Warlock's ultimate ability stun goes through spell immunity. E.g.: Crystal Maiden, Witch Doctor, Enigma, etc.

* Being a hero with low health and abysmal mobility, Lina can nuke her down easily.
* Since Crystal Maiden's Freezing Field is a channeled ability, Lina can use her Light Strike Array to cancel it easily.

* Heroes who can easily harass Crystal Maiden out of lane in the early game (Clinkz, Viper) can prevent Crystal Maiden from being able to level effectively, and can ultimately slow down her level 6, 12, and 18 to a point where enemy carries already have items to address her ultimate.

* Heroes who are strong against mobile heroes: Disruptor, Bloodseeker, Kunkka, Keeper of the Light.

* Low mobility heroes: Heroes with no/little means of traveling fast have difficulty getting to/away from Bounty Hunter due to his slowing Jinada and hastening Track. Few examples of such heroes are: Crystal Maiden, Sniper, Ursa, Witch Doctor, etc.

Additional:
* Shuriken Toss's stun is useful for cancelling Freezing Field from a distance.
* Track can be used for revealing Crystal Maiden when she uses Glimmer Cape.
* Jinada does burst physical damage (which is even bigger if dealt under Track's crits), which is effective due to Crystal Maiden's low HP and armor.
* Bounty Hunter likes to stay hidden from the fight and is less likely to get caught by Crystal Maiden's spells.

* Fragile supports who die in a few hits against Sven's high physical damage: Crystal Maiden, Vengeful Spirit, Dark Willow.

* Any hero with a low HP pool is easy for Tinker to nuke down: Crystal Maiden, Enchantress, Gyrocopter, Lion, Riki, Techies, Terrorblade, Necrophos, Invoker.
