Naga Siren/Counters

Bad against...

 * Both of Lion's and  destroys Naga Siren's illusions in an instant. Making it hard to teamfight or push against a team with Lion.


 * Outworld Devourer's deal bonus damage to illusions which is a very good way dealing with Naga Siren's illusions.


 * Huskar's ultimate ability does almost one-hit kill a Naga Siren illusion because of the percentage based damage. This makes it very hard to push against a Huskar.


 * Zeus' abilities deal high amount of burst magical damage which ignores Naga Siren's high armor. Zeus' is also a good way to destroy pushed in waves and clumped up Naga Siren illusions.


 * Timbersaw's innate tankyness is very hard to deal with as Naga Siren. Timbersaw's high Pure Damage and spammable nukes can also destroy Naga Siren's illusions very fast.

Good against...

 * Ensnare disables QoP's Blink, making her escape impossible.


 * Reason


 * Reason


 * Esnare disables Lanaya's invisibility and Blink Dagger (Core Item on TA), and your illusions easily will break her Refraction.


 * Song of the Siren will render Guardian Angel useless.

Others

 * Bounty Hunter
 * Techies
 * Lycan

Works well with...

 * Well, both come from the sea. Seriously, Tidehunter's Ultimate works very well with Song of the Siren as TF initiation.


 * Another sea teammate. Same reason that Tidehunter.


 * Song of the Siren+ Kinetic Field+Static Storm, and the enemies won't be able to counterattack in a team fight, especially if Disruptor has Aghanim Scepter.
