* Aghanim's Scepter gives Leshrac access to 
Nihilism ability, that allows him to turn himself along with Naga Siren and her illusions to turn ethereal. And to make things worse, Nihilism can slow Naga Siren and her illusions, make them more vulnerable to magical damage and unable to fight back while Leshrac moves faster and does not take increased magical damage for it's duration.
Ogre Magi
* It is difficult for Mars to trade blows with Ogre Magi in the early game thanks to his high base health, resistance and Ignite.

Fireblast can interrupt and mitigate Mars from performing his skill combos, especially in combination with 
Multicast.
Ogre Magi
* 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.

Disruption

* Leshrac does not have any buffs that can be removed by 
Demonic Purge.

* An attempt to save an ally using Disruption can easily become a perfect setup for a Split Earth for the enemy.
* Disruption does not stop Diabolic Edict and Pulse Nova once they start pulsing, and even worse it provides a safe shelter for Leshrac to keep pumping up his powerful AoE damage onto the battlefield.
* Shadow Demon doesn't have the burst damage to take Leshrac out of the fight quickly, although Demonic Purge can help his allies kill a squishy Leshrac.
Ogre Magi
* 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.

* Heroes with wide AoE abilities will reveal Monkey King through Mischief: Necrophos,

Lifestealer with Aghanim's Scepter upgraded

Sven, 
Tiny, 
Wraith King, Ogre Magi.

Leshrac
* Pulse Nova deals an insane amount of damage in an area around him, which can quickly wear down Meepo clones.
