* Mars has no way to trade with Ogre Magi in the early game thanks to his high base health, resistance and Ignite.
* Once Ogre Magi gets level 2 he may also have Bloodlust, which makes him even harder to deal with in lane.
* Fireblast can be ridiculously strong later on in the game for controlling Mars.
* Spear of Mars, which is Mars' main source of damage in the early game, cannot guarantee kills early on Ogre Magi.

* Heroes that can save their allies can be a big problem for Mars: Dazzle, Omniknight.

* Heroes that can cancel Charge of Darkness: Ogre Magi, Earthshaker, Lion .

* Heroes that can slow Charge of Darkness by a huge amount: Venomancer, Viper, Dazzle, Arc WardenLion

* Nature's Prophet treants can be cleared by Ignite or Multicast Hand of Midas
* Fireblast and Unrefined Fireblast prevents Nature's Prophet from using Teleportation.

* Multicast Fireblasts over the course of fights are a decent nuisance to stall Sven's massive damage output.
* Bloodlust and Ignite gives Ogre Magi's team the movement speed difference needed to chase and/or disengage against a Sven and his Warcry.
* Ignite provides strong damage over time to pressure Sven early on in the laning phase and keep his health low, delaying his transition into the jungle. Ignite is also an easy way to disrupt Blink Dagger, Sven's most popular way of initiation.
* Ogre Magi's presence in the laning phase both in terms of damage and durability keeps high pressure on Sven in lane.
* Purchasing an Aghanim's Shard allows Ogre Magi to greatly reduce the burst damage of Sven, who tends to build items focused on damage per hit instead of attack speed.

* Shallow Grave saves an ally whom Terrorblade has used Sunder on.

* Shallow Grave can prevent death to ally that is trapped inside Chronosphere.
* Shadow Wave let Dazzle to heal allies and damage enemies from outside Chronosphere.

* Shallow Grave can be used to save an ally during Dismember and Rot.
* A combination of Bad Juju, Poison Touch, and items like Desolator or Solar Crest can tear off Pudge's low armor, making him even more vulnerable to physical damage.

* The damage block instances of Refraction can be burned down with Ignite.
* Fire Shield effectively reduces the burst damage from a Meld-charged ambush from Templar Assassin, provided the spell is cast beforehand.

* Ignite can prevent Earthshaker from escaping and/or initiating with Blink Dagger.
* Fireblast and Unrefined Fireblast may help prevent Earthshaker follow through with his combo after landing an Echo Slam.

* A well-timed Fireblast with Multicast can prevent Weaver from escaping with Shukuchi and even Time Lapse.
* Ignite's high damage early on applies heavy pressure onto Weaver's very small health pool.
* However, the slow from Ignite is generally useless against Shukuchi, and Time Lapse dispels it if needed.

* Fireblast is a good tool to interrupt Io during its escapes through Tether.
* Ignite can be one of the few spells with enough total damage to out-trade the sustained healing Io provides for its fellow laner.
* However, picking other supports that focus less on the laning phase is generally a better choice against Io.

* 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.

* Dazzle's Shadow Wave is a spammable healing ability that spreads around his entire team, slowing the death of his teammates as effectively as Necrophos spreads damage to them.
* If not immediately, Shallow Grave delays his ally from gradually dying to Necrophos' abilities, especially Reaper's Scythe.
Additional:
* Reaper's Scythe is very predictable and gives you plenty of time to react with Shallow Grave: just keep a close eye on allies below 50% health.
* However, be sure to use Shadow Wave on that ally immediately after, or they will die from Heartstopper Aura when the Shallow Grave ends!

* Shadow Wave provides good sustain against Tinker's spammable abilities.
* Shallow Grave can stop Tinker from bursting down a target.

* Hand of God has a long cooldown, so damage over time spells can be hazardous for Chen, forcing him to use it prematurely: Jakiro, Venomancer, Viper, Dazzle, Phoenix.

* Techies struggles early game against heroes with naturally large strength and health regeneration such as Pudge, Axe or Ogre Magi, as the player is forced to lay down more mines than usual to kill these bulkier heroes.

* Heroes that excel at grouping up with their team very early will be able to take advantage of a Clinkz that tries to pick off heroes that are alone: Brewmaster, Dazzle, Tidehunter.

* Side lanes with disables will greatly reduce the likeliness Void Spirit will be willing to rotate: Sven, Tiny, Wraith King, Ogre Magi.

* Heroes with abilities that can save teammates are also effective such as Shadow Demon, Dazzle, Oracle, Bane, Pugna, Tusk, Winter Wyvern, Io, Underlord, Treant Protector and Keeper of the Light.

* Heroes with armor reducing abilities greatly hinder Visage's defense like Slardar and Dazzle.

* Heroes with abilities that reduce armor will make Huskar very vulnerable: Weaver, Dazzle, Bristleback, Vengeful Spirit.

* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's steady damage output, Dazzle has plenty of time to Shallow Grave anyone Clockwerk initiates on.
Additional:
* Shadow Wave will hit Clockwerk every time when he's fighting with an enemy inside Power Cogs.
* Due to Clockwerk's slow damage output, Dazzle will have more than enough time to Shallow Grave any enemy Clockwerk initiates on.

* Shallow Grave prevents Bloodseeker from replenishing his health by finishing off enemies.

* Shallow Grave prevents Legion Commander from killing her opponents in Duels.
* Shadow Wave will heal an ally caught in a Duel, as well as dealing damage to Legion Commander.
