* Nethertoxin disables Aftershock, which removes the stun and bonus damage from Enchant Totem and Echo Slam.

* Nethertoxin breaks the damage block from Bulwark.
* Poison Attack and Viper Strike's slows make it difficult for Mars to contribute to fights due to his low mobility.

* Nether Ward reduces the amount of abilities Mars can use during fights and forces Mars to be careful about the heavy mana cost of Arena Of Blood.
* Pugna is one of few heroes that can contest Mars' ability to push and defend towers early on.

* Legion Commander is both good and bad vs Mars, on the plus side she can dispel Spear of Mars with Press the Attack and is a good Silver Edge carrier. However, Mars is not an ideal Duel target, as Bulwark will force her to 1: Buy Silver Edge, and 2: Hit Mars with it before the Duel, allowing a skilled Mars to react, especially with Eul's Scepter of Divinity. In teamfights, Mars will happily draw attention after using his abilities, and tank the Duel with all spells on cooldown.

This is especially noticeable in the earlier stages of the game before allies buy Black King Bar and rely on this less. Even during the late-game, Tusk can purchase a Blink Dagger to save allies that are caught before Black King Bars can be used by Blinking in and Snowballing out.
* Tag Team is a constant threat to Mars in-lane, as it deals significant damage and slow, making Bulwark slightly ineffective.
* It is worth noting that Ice Shards can be detrimental to Tusk's own team by creating terrain that Spear of Mars can latch on, though using it conservatively is a good enough solution in most cases.

* Shrapnel can be used to disable Earthshaker's Blink Dagger from long range.
* Take Aim allows Sniper to harass Earthshaker in lane, and stay out of Echo Slam initiation radius.

* Heroes with invisibility and high mobility can jump on and focus down Earthshaker before he has a chance to initiate: Clinkz, Slark, Storm Spirit

* Spectral Dagger can be used to traverse past Fissure.
* Haunt will usually disable Earthshaker's Blink Dagger prior to a teamfight, preventing him from initiating.
* On the other hand, Haunt will amplify damage done from Echo Slam. Use this to your advantage.
Additional:
* Spectre can use Haunt to intercept and disrupt Earthshaker's initiation attempts.
* Spectral Dagger can be used to traverse past Fissure.
* Earthshaker often travels alone when he is trying to initiate, so Desolate can be very effective against him.
* Beware that the Haunt illusions amplify the damage done from Echo Slam, which can prove fatal for Spectre's own team.
