Wave of Terror can be used to scout an area to prevent juking or initiate with 
Telekinesis, as well as reducing the armor of enemy team during a teamfight.
* 
Nether Swap does what it does - saving an ally from danger, initiating on an enemy, or helping with caughting a fleeing hero.
* With Aghanim's Shard, Rubick can lift himself up and drop quickly to a place of safety after the swap. Note that Rubick can only choose to either disable the enemy or save himself at one time with Telekinesis.
Additional:
* All of Vengeful Spirit abilities are very good for Rubick to 
Spell Steal:
* Magic Missile provides an additional nuke/disable to pair with 
Fade Bolt and Telekinesis, respectively.
* Wave of Terror serves as a good scouting/armor reduction skill that Rubick and his team can benefit from.
* Nether Swap complements Rubick's mobility and pairs well with other mobility items he usually builds. He can also use it to save an ally from danger.

* 
Fate's Edict prevents all magical damage that comes from Dark Seer's abilities.

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.
Vengeful Spirit
* Vengeful Spirit should carefully consider whether to use her Nether Swap on Tidehunter, as it can easily position him for a 
Ravage on Vengeful Spirit and her allies.
* Due to Magic Missile's high damage, 
Kraken Shell will often proc and clear Tidehunter's debuffs.
Vengeful Spirit
* Magic Missile has a considerably long cast time, making it difficult to stop 
Charge of Darkness with it.
* Other than Magic Missile, Vengeful Spirit has no way of canceling 
Nether Strike.
Dark Seer
* 
X Marks the Spot prevents Dark Seer or his allies from escaping with Surge.
Vengeful Spirit
* 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.
Dark Seer
* 
Flame Guard makes Dark Seer not deal any damage with his skills to Ember Spirit.
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.
Vengeful Spirit
* 
Ball Lightning disjoints an incoming Magic Missile, avoids Wave Of Terror, and allows Storm Spirit to easily escape if he ever gets Nether Swapped.
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.
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.
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 Weaver or Queen of Pain.
Vengeful Spirit
* Heroes who have a high mobility (Queen of Pain, Storm Spirit, Slark, etc.).

* Fragile supports who die in a few hits against Sven's high physical damage: Crystal Maiden, 
Vengeful Spirit, 
Dark Willow.
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.
Vengeful Spirit
* With the exception of Magic Missile (unless the player takes the Level 25 Talent "Magic Missile Pierces Spell Immunity"), all of Vengeful Spirit's spells ignore Spell Immunity. This also makes her good against heroes with built-in Spell Immunity like 
Lifestealer or 
Juggernaut or heroes that tend to pick up 
Black King Bar, like 
Sven.
Vengeful Spirit
* Frail heroes who lacks mobility: Crystal Maiden, 
Enigma, Dark Willow, Vengeful Spirit.
Vengeful Spirit

Impale and 
Mind Flare.
* 
Spiked Carapace is easy to use against a Wave of Terror or Magic Missile.
Dark Seer
* Heroes who rely on damage over time as Spiked Carapace can block and reflect only one instance of damage: Jakiro, 
Viper, 
Venomancer, 
Huskar, 
Ember Spirit, Dark Seer, 
Sand King, 
Doom, 
Dawnbreaker. However, this also means they are easily stunned.
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.
Vengeful Spirit
* Heroes with catch to disrupt Sniper's positioning and deliver him into the enemies: 
Batrider, Disruptor, 
Pudge, Vengeful Spirit.
Vengeful Spirit
* 
Nethertoxin disables Vengeance Aura.
* Vengeful Spirit has no mobility spells aside from Nether Swap, which Viper can take advantage of with his slows.
* Viper can easily bully Vengeful Spirit out of a lane with 
Poison Attack.
Additional:
* 
Viper Strike can disable the attack damage bonus from 
Vengeance Aura and the components of Nether Swap.
* Both Magic Missile and Wave of Terror are counteracted by 
Corrosive Skin, making Vengeful Spirit's fighting harder against Viper.
Dark Seer
* Heroes who do not have nor rely on passive abilities make Nethertoxin much less effective: 
Clinkz, 
Pugna, 
Nature's Prophet, Dark Seer, 
Lycan, 
Tusk
Vengeful Spirit
* Vengeful Spirit has no strong AoE nuke or disable against Phantom Lancer's Illusions.
* Phantom Lancer is a natural 
Diffusal Blade carrier, which reduces Vengeful Spirit's low mana pool very quickly, leaving her defenseless.
* 
Doppelganger can dodge Vengeful Spirit's abilites.
* 
Phantom Rush with his illusions can chase Vengeful Spirit efficiently.
Dark Seer

Phantom Lancer, 
Chaos Knight, 
Naga Siren, 
Terrorblade.

Vengeful Spirit
* Lina can burst Vengeful Spirit down, provided she can land 
Light Strike Array before Vengeful Spirit lands her Magic Missile.
* 
Laguna Blade deals massive damage, often being enough to kill a squishy Vengeful Spirit.

Flaming Lasso, Pudge with 
Meat Hook and Vengeful Spirit with Nether Swap.
Vengeful Spirit
* Magic Missile can stun Chen and deal heavy damage to him.
* Wave of Terror weakens durability of Chen and his creeps.

Vacuum and Ion Shell can clear a wave of Chen's Creeps effectively.
* Surge applies haste movement and negates the slow from 
Penitence, allowing Dark Seer to easily escape from Chen and his creeps.

Normal Punch from Aghanim's Scepter can often kill Chen or any of his allies before he can save them with 
Hand of God.

Invoker, Legion Commander, 
Mars, 
Primal Beast, 
Riki, 
Shadow Shaman, 
Silencer, Vengeful Spirit, 
Void Spirit.
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.

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.

* Past the mid game, an isolated Vengeful Spirit makes for an easy kill for Anti-Mage.
Blink away to disjoint the stun or reflect it back against Vengeful Spirit with 
Counterspell.
* Magic Missile is the only disable Vengeful Spirit has against Anti-Mage, but he can either
* Nether Swap isn't very effective against Anti-Mage - if used offensively, Anti-Mage can simply blink away to safety, and if used defensively, Blink's low cooldown allows him to persistently chase as well.
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.
*
