* The dragon's splash damage wears down his illusions.
* Early harassment with Breath of Fire hinders his farming.
* Fireball stops his pushes and allows for a defence.

* Mortimer Kisses can make quick work of Naga Siren's illusions.
* Scatterblast and Firesnap Cookie's AoE damage are also decent ways to deal with Naga's illusions.

* Mortimer Kisses can deal a large amount of damage to Void during Chronosphere, either outright killing him or forcing him out before he can kill any allies caught in his ultimate.

* Despite the armor reduction from Meld, Templar Assassin's reliance on physical damage and medium attack speed is unlikely to harm Dragon Knight.
* Templar Assassin's Refraction charges also get quickly removed by the damage over time from Dragon Knight's ultimate.
Additional:
* The damage over time from Dragon Knight's Elder Dragon Form rapidly burns down Refraction, allowing him to attack her.
* Also, Breathe Fire reduces Templar Assassin's damage and Dragon Tail is a stun with a considerable duration, letting him and his team whittle her health down once her defenses wear off.
* Templar Assassin will struggle to kill Dragon Knight thanks to his high armor and health regen from Dragon Blood as she deals entirely physical damage.

* Death Ward does little damage against Dragon Knight's armor, and Dragon Knight's high health regeneration minimizes damage from Maledict.

* Heroes that are hard to gank: Dragon Knight, Mars, Centaur Warrunner.

* Heroes with high armor like Dragon Knight, or with abilities to cause attacks to miss like Phantom Assassin, Riki and Tinker will be hard to deal with, as Clinkz relies almost entirely on physical attacks.

* A badly placed Power Cog makes it easier for Snapfire to aim Mortimer Kisses on Clockwerk

* Mortimer Kisses can reduce Omniknight's impact in teamfights. Omniknight's Heavenly Grace cannot purge multiple stacks of Mortimer Kisses. The damage is also magical, making Omniknight's ultimate, Guardian Angel, useless.

* Dragon Knight's heavy armor negates Vendetta's burst physical damage. His large HP pool also gives him a good chance of surviving Nyx Assassin's follow-up nuke damage.

* Heroes with summons that are destroyed by a fixed number of attacks: Undying's Tombstone, Gyrocopter's Homing Missile, and Zeus's Nimbus.
