Dark Seer
* 
Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
Pangolier
* 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 works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Dark Seer
* Heroes with fast movement abilities will suffer huge damage when afflicted by Rupture: 
Spirit Breaker, Earth Spirit, 
Dark Seer.
Additional:
* 
Rupture can deal a lot of damage to either a surged Dark Seer or his allies and prevent the target from getting into position.
Pangolier
* Rupture works through 
Rolling Thunder and 
Swashbuckle, greatly reducing Pangolier's mobility.
Additional:
* 
Thirst provides constant sight and speed to Bloodseeker, allows him to catch up a fleeing Pangolier through all of his mobility.
* Rupture is a great threat to Pangolier, causing him to take heavy damage if he uses Swashbuckle and especially Rolling Thunder, forcing him to stop his ultimate prematurely, or keep rolling to his death.
Dark Seer
* Dark Seer's strength lies in his high-mana cost skills. So 
Mana Break can be a great nuisance for him, since it can reduce his mana and prevent him from casting his spells.
* 
Mana Void can deal a lot of damage if Dark Seer spent a lot of mana on his abilities.
Pangolier
* 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 works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.
Dark Seer
* Dark Seer's only disable is Vacuum. Though he starts off with high armor and health, he'll eventually have a hard time dealing with high mobility heroes such as

Dark Seer
* Abilities that deal low damage with high amounts of instances are irrelevant against Pudge during Flesh Heap's active: 
Gyrocopter's 
Rocket Barrage and Dark Seer's 
Ion Shell are just a couple examples.
Pangolier
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: 
Axe, 
Beastmaster, 
Enigma, 
Magnus, 
Pudge, 
Batrider, 
Bane, 
Winter Wyvern
Dark Seer
* 
Fortune's End dispels Ion Shell and Surge, making any gank attempt on Dark Seer in the laning phase likely to succeed.
* 
Fate's Edict prevents all magical damage that comes from Dark Seer's abilities.
* Fortune's End dispels Ion Shell on creeps, which Dark Seer relies on to farm and zone.
Additional:
* Fortune's End can dispel Ion Shell, a skill that helps Dark Seer immensely in the laning phase, as well as 
Surge, a move-speed buff, effectively allowing Oracle to control Dark Seer, especially in the laning phase.
Pangolier
* 
Split Shot will keep attacking Pangolier even when he is rolling around.
* 
Stone Gaze stuns Pangolier during Rolling Thunder, or forces him to roll away.
Dark Seer
* Strong laners are usually at a disadvantage because of how well Sven can jungle. Heroes such as Dark Seer. 
Underlord and 
Legion Commander may find that later Sven takes care of them very quickly after some jungle farming.
Pangolier
* 
Warcry can protect Sven and his teammates from Swashbuckle.
* With 
Black King Bar, Sven will be able to protect himself from most of Pangolier's skills.
Pangolier
* Heroes who rely on burst physical damage are affected by Lucky Shot's disarm: 
Terrorblade, 
Sven, 
Clinkz, 
Windranger, 
Alchemist, 
Dragon Knight, Legion Commander
Pangolier
* 
Astral Imprisonment protects an ally for much of Rolling Thunder's duration, especially at the lower levels. As Rolling Thunder has a considerable cast animation, an Outworld Destroyer with 
Blink Dagger can initiate on him and destroy his timing.
Pangolier
* Pangolier will proc Retaliate several times if he attempts to use Swashbuckle on Centaur Warrunner.
* Centaur can cast Stampede to allow all of his allies to easily avoid Rolling Thunder.
* Centaur's tankiness makes it hard for Pangolier to burst him down in the late game.
Additional:
* When Swashbuckle hits Centaur Warrunner, 
Retaliate will deal significant damage, as it procs off every strike made.
* 
Stampede helps allies avoid or disengage from Pangolier during Rolling Thunder, as well as neutralizing the slow debuff from Lucky Shot.
Dark Seer
* The constant dispel from Demonic Purge will make any attempt to save the victim or himself by Surge become futile. For what it's worth, Demonic Purge will also dispel Ion Shell.
Dark Seer
* 
X Marks the Spot prevents Dark Seer or his allies from escaping with Surge.
Pangolier
* 
Charge of Darkness can be used to chase down Pangolier if he escapes with Swashbuckle or Rolling Thunder.
* 
Nether Strike ignores Rolling Thunder's spell immunity, and will still hit Pangolier if he rolls or dashes away.
Dark Seer
* Dark Seer relies on Surge for most of his mobility, so he's not very vulnerable to slows, but much more to root effects and walls or pseudo-walls such as 
Disruptor's 
Kinetic Field or 
Slark's 
Pounce.
Pangolier
* 
Dark Pact easily purges away both slow and disarm effect from Lucky Shot.
* With Pounce now applying leash to the target, Pangolier is helpless against Slark since both his Swashbuckle and Rolling Thunder will be disabled. Pounce also help Slark to easily escape from Rolling Thunder.
Dark Seer
* Heroes with AoE abilities will hit Slark in Shadow Dance: 
Lina, 
Jakiro, Underlord, 
Leshrac, Dark Seer, 
Earthshaker, 
Timbersaw, 
Crystal Maiden.
Pangolier
* 
Chronosphere's large obstacle denies Pangolier the room to roll around during teamfights, as well as wasting his ultimate's duration.
Pangolier
* 
Illusory Orb and 
Waning Rift provides great mobility, allowing Puck to catch up Pangolier when he is attempting to disengage with his own skills.
* 
Dream Coil's leash act almost as a literal silence to Pangolier, disabling half of his arsenal and also piercing his spell immunity during Rolling Thunder. Also Dream Coil's very long duration will make Pangolier wasting his entire ultimate rolling in place.
Additional:
* Dream Coil and Wanning Rift prevent Pangolier from using Swashbuckle and Rolling Thunder. If Puck has 
Aghanim's Scepter, Dream coil will stop Rolling Thunder from moving entirely.
Pangolier
* 
Soulbind ignores spell immunity, forcing Pangolier to roll in place during his ultimate as well as anchoring the other victim to his vicinity.
Pangolier
* 
Ice Shards can easily interfere with Rolling Thunder, making him stuck inside the arc and wasting his ultimate. Do not panic and use Shield Crash to get out of that position.
* 
Snowball helps Tusk and his allies follow a fleeing Pangolier, keep in mind that the Pangolier can always counter-initiate with his Rolling Thunder.
* 
Walrus PUNCH! deals heavy damage even during his Rolling Thunder.
Pangolier
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, Beastmaster, Enigma, Magnus, Pudge, Batrider, Bane, Winter Wyvern

Keeper of the Light, 
Huskar, Dark Seer
Pangolier
* Heroes with spell immunity can still be disabled by Fiend's Grip and damaged by Brain Sap: 
Juggernaut, 
Lifestealer, 
Pangolier.
Pangolier
* 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 works, they can adjust their movement to avoid it entirely and of course outplay the Pangolier player.

Pangolier
* Certain heroes can mess up with Pangolier's positioning and timing (especially if he intends to use Rolling Thunder during combat): Vengeful Spirit, Keeper of the Light, Huskar, Dark Seer
Dark Seer
* A Sniper who is somewhat competent at positioning is hardly going to be affected by any of Dark Seer's spells thanks to 
Take Aim.
* However, an illusion of Sniper made with Wall of Replica is extremely powerful, and hard to deal with.
Pangolier
* Powerful physical hitters that can destroy Pangolier during his rolling from afar: Drow Ranger, Sniper, Templar Assassin, Arc Warden
Pangolier
* Pangolier can easily get close to Sniper with Swashbuckle and Rolling Thunder, negating Sniper's range advantage.
* Lucky Shot disarms Sniper and leaves him unable to effectively fight back.
Pangolier
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, Beastmaster, Enigma, Magnus, Pudge, Batrider, Bane, Winter Wyvern
Dark Seer
* In general, heroes who are melee with no way to fight back can be very easily poked by Monkey King to gain his Jingu Mastery stacks: Dark Seer, 
Riki, 
Rubick.
Pangolier
* Heroes with other kind of disables that pierce spell immunity can hold Pangolier in place during Rolling Thunder: Axe, Beastmaster, Enigma, Magnus, Pudge, Batrider, Bane, Winter Wyvern
Dark Seer
* Ion Shell zones out Broodmother in the laning phase, and can kill her spiderlings if used on one Spiderling in a group.
* 
Vacuum can pull Broodmother out of the treeline.
Additional:
* Ion Shell is a very powerful weapon against Broodmother's Spiderlings and makes her laning much harder.
Pangolier
* Swashbuckle can be used for Pangolier to escape or kill Broodmother's spiders. Combined with 
Lucky Shot Pangolier can potentially disarm Broodmother preventing her from lifestealing off enemies.
* 
Shield Crash can be used for wave clear to deal with Broodmother's spiders.
* Rolling Thunder can be used as an escape or a means of initiating on Broodmother.
Additional:
* Swashbuckle and Shield Crash quickly destroys Broodmother's spiderlings and spiderites.
* Lucky Shot's disarm is very valuable when dealing with a Broodmother during her 
Insatiable Hunger.
Dark Seer
* Heroes that rely on illusions typically spawn very strong illusions inside Dark Seer Wall of Replica that he can use against them or their team: 
Phantom Lancer, 
Chaos Knight, Naga Siren, Terrorblade.
Additional:
* Ion Shell helps taking down illusions quickly, making it easy to identify the real Phantom Lancer.
* Surge allows Dark Seer and his teammates to run away from Phantom Lancer, who relies on his 
Phantom Rush to chase enemies.
Pangolier
* Swashbuckle,
Maelstrom or 
Diffusal Blade allow him to quickly destroy Phantom Lancer's illusions.
* Pangolier's high mobility allows him to easily escape from Phantom Lancer, through both Phantom Rush and Diffusal Blade.
* Phantom Rush will cause Phantom Lancer to be stunned by Rolling Thunder, or set himself up for a Shield Crash.
Additional:
* Pangolier's AoE abilities especially Shield Crash, are very effective against Phantom Lancer's illusions.
Dark Seer
* Dark Seer's Vacuum and Ion Shell allows him to clear a wave of Terrorblade's illusions.
* Because Terrorblade often builds items that require 
Ultimate Orb like 
Manta Style and 
Eye of Skadi, Dark Seer can create a very strong illusion of Terrorblade with 
Wall of Replica and 
Normal Punch from Aghanim's Scepter.
* If Dark Seer can use Vacuum to help teammates land their AoE abilities, Terrorblade will be quickly killed before he even gets a chance to use Sunder.

Gravekeeper's Cloak charges.
Pangolier

Dark Seer
* 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.
Pangolier
* 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%).

* Surge applies haste movement and negates the slow from 
Penitence, allowing Dark Seer to easily escape from Chen and his creeps.

Dark Seer
* Venomancer is a low health hero and low range hero who is easy to harass with Ion Shell on a creep in the early game.
* Venomancer depends entirely on all his slows to keep distance or chase, but since Surge ignores slows, it is nearly impossible for Venomancer to hunt or run away from Dark Seer or his surged teammates.
Pangolier
* Swashbuckle is an auto attack and therefore ignores Mars' Bulwark.
* Shield Crash upgraded with Aghanim is an auto attack and therefore ignores Mars' Bulwark.

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.
Pangolier
* Lucky Shot can disarm Legion Commander and reduce her armor, which can reduce her chances of winning a duel. If an ally is targeted, Pangolier can simply use Swashbuckle to inflict it on her.
* If an enemy Pangolier casts a well-timed Rolling Thunder before Legion Commander can cast Duel, it might result in her chasing down Pangolier until his or her ultimate ends, whichever duration ends first, resulting in an open window for enemy allies to target Legion Commander, making her vulnerable and susceptible to any source of attacks. If Legion Commander has an Aghanim's Scepter in her inventory, the risk of wasting a solid 8 seconds would result in a futile duel.
* Dueling Pangolier is normally a mistake, Pangolier can disarm you in the duel, and potentially gain some Duel damage, Only duel Pangolier if at least 1 ally is nearby, and he is on low health, And even then, be wary, A good duel can easily turn against you with one Lucky Shot (Due to Lucky Shot lasting 4 seconds).
Additional:
* Swashbuckle can be used to disarm Legion Commander while she is Dueling an ally, granting her opponent a considerable advantage, Lucky Shot lasts 4 seconds at most wasting Legion Commander's entire Duel, (Or half, if Legion Commander has the Scepter).
* Legion Commander will try not to duel Pangolier alone, as she will almost inevitably lose, thanks to Lucky Shot's disarm, If Legion Commander wants to duel a Pangolier, she must be with atleast a teammate, and if she has her scepter, 3 or 4 teammates.
* Legion Commander is often with her allies, allowing you to rack up some considerable damage resistance with Shield Crash.

Shield Crash is a great area-of-effect ability on Rubick primarily for farming.
Swashbuckle is a great reposition and damage ability on the hands of Rubick.
Lucky Shot, so the ability might be less effective as a source of damage.
Pangolier may build items such as 
Maelstrom or 
Diffusal Blade to add up attack multipliers to the ability, and Rubick can choose to build similar items should he choose the route.
Rolling Thunder is a unique ability that allows Rubick to jump in the center of teamfight while protected by Spell Immunity, creating chaos and possibly chain stun the enemy team.
Rolling Thunder negates the collision damage and stun from Pangolier's 
Rolling Thunder.
Rolling Thunder, making it faster than 
Pangolier himself.
Rolling Thunder - throwing an enemy en route by casting 
Telekinesis can be a good idea.
Rolling Thunder should be made quickly as Pangolier cast 
Shield Crash very often during Rolling Thunder.
