Bristleback continuously and to massively reduce to damage dealt to him: 
Arc Warden,

Venomancer
* 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.

* The damage-over-time abilities of Phoenix disable Sand King's Blink Dagger very often.
Sand King
* 
Ravage, being an AoE disable, cancels Epicenter's channeling from a long range, limiting his potential to counter-initiate.

Black King Bar, then channel Epicenter, then finally initiate with Blink Dagger.
Sand King
* Both 
Arcane Curse and 
Last Word punishes casters with spammable spells such as Sand King.

Thundergod's Wrath, disables Sand King's Blink Dagger, effectively reducing Sand King's initiation and counter-initiation potential.
* 
Lightning Bolt deals damage to Sand King in Sand Storm and reveals him. It also interrupts channeling of Epicenter.
Venomancer
* Venomancer's damage-over-time abilities are easier to heal through with numerous Shadow Waves than other types of damage, and it's simple to time a Shallow Grave until the last possible second to save a teammate from them.

Venomous Gale and Poison Nova.
* Venomancer lacks mobility and has low base health, so he can be killed by Walrus PUNCH!

Ancient Seal.
Additional:

Fortune's End can dispel Venomous Gale and Poison Sting from allies.
* 
Fate's Edict grants 100% magic resistance to target, inhibiting the damage from Venomancer abilities.

Berserker's Blood rendering them ineffective

Sand King
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, Jakiro, Pugna, Earthshaker.

Venomancer
* Slardar can attack through Plague Wards and gain Bash of the Deep charges, and Templar Assassin can spill Psi Blades through Plague Wards too.
Sand King
* Sand King can quickly remove her 
Refraction with his Sand Storm.
* Once Refraction is down, she is very vulnerable to Epicenter's high magic damage.
Venomancer
* Venomancer's entire arsenal deals lingering damage over a long time and therefore burns through her Refraction very quickly. Not only that, his persistent slow from Poison Sting (it can be re-applied again and again with Plague Ward) allows his team to catch up to her even with the disruption from her Psionic Trap.
Additional:
* Venomous Gale and Plague Wards allow to quickly melt through Refraction charges.
* Both Poison Nova and Venomous Gale hit invisible units, so 
Meld cannot be used defensively.
Sand King
* Heroes with no mobility will take some good damage from Sand King's spells: Dragon Knight, Jakiro, Pugna, Earthshaker.

Sand King
* 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.

Venomancer
* Plague Wards are very hard for Batrider to play against as they provide a lot of vision as well as disable Blink Dagger for a long duration.
Sand King

* However, Epicenter is usually a non-issue against Doppelganger.
Venomancer

Bulwark.

Arena of Blood.
Venomancer
* 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.
Venomancer
* Venomancer's poison damage over time is very effective against Spectre, who tends to lack magic resistance during the early to mid game.
* Venomancer's multiple slows greatly reduces Spectre's movement speed and mobility.
* Plague Wards can scout out Spectre while she is hiding in trees.
Additional:
* Venomancer's poison damage-over-time are very effective against Spectre, which is lack of magic resistance from early to mid game.
* Venomancer's multiple slows greatly reduces Spectre's low mobility, even through 
Spectral Dagger.
* Plague Wards reveals Spectre while she is hiding on trees.
Sand King
* Sand King's massive area damage output, particularly Epicenter, allows him to quickly take down Chaos Knight and his illusions.
* Sand King can also apply Caustic Finale to illusions with attacks for extra damage when they die.
Sand King
* Burrowstrike allows Sand King to escape from 
Eclipse or to close the gap on Luna and finish her off.
* Sand Storm allows Sand King to harass Luna more efficiently than she does with 
Lucent Beam, as it makes him invisible for it's duration and while in it, rendering him safe from both, Lucent Beam and Eclipse and forcing Luna to buy 
Dust of Appearance more often.
* Caustic Finale allows Sand King to deal serious damage to both, Luna and her allies, which is especially hazardous in laning stage as Luna's attack range is short.
* Epicenter combined with Burrowstrike and Sand Storm can often kill Luna before she can do anything because of her low health and strength gain.
* Overall, Sand King forces Luna to play more defensively instead of offensively, and for the same reasons, Sand King makes a very powerful ally for Luna when they are in the same team.

Venomancer
* Due to her slow movement speed,heroes with crowd control and slows can shut down Dawnbreaker:

Sand King

Sand King
* Burrowstrike is one of the best and easiest steals for Rubick and Sand King should be careful when playing against him - it's much better to give away Sand Storm.
Venomancer
*
Venomous Gale is a great ganking and farming skill.
Plague Ward serves as a flexible ability for pushing, ganking, farming and scouting. The innate 
Poison Sting also works on the stolen 
Plague Ward with half the damage.
Poison Nova, if stolen and cast, puts a huge damage-over-time debuff on the enemy team, even greater than Venomancer himself with the help of 
Arcane Supremacy.
Spell Steal has a greater cast distance than the effect area of 
Poison Nova, allowing Rubick to steal the spell while staying at the back.
Venomancer suffers from mana pool problems, while Rubick has relatively high intelligence gain and can cast the same set of spells at ease.
Spell Steal. Stealing Plague Wards makes them apply Poison Sting as well.
