Beastmaster/Counters

Bad against...

 * effectively nullifies 's single-target initiation.


 * negates Beastmaster's attack speed, making her hard to kill even if stunned by.
 * Enchantress can also take control of Beastmaster's summons.


 * Having many summons out will cause to deal extra damage.


 * makes laning alone very hard for Beastmaster.

Others

 * can also take control of Beastmaster's summons.
 * While a Boar or Hawk may not seem like much, this becomes more problematic if enemies take control of a unit, which Beastmaster often uses.
 * can turn Beastmaster's summons against him or his team with.

Items

 * blocks, making Beastmaster much less useful.
 * can steal Beastmaster's summons.

Good against...

 * Beastmaster's Hawk will often see on the minimap, giving his team a chance to move away, or engage during its cooldown.


 * takes Sven out of the fight completely, even with.


 * Attacks from Boars and will quickly wear down.


 * and the slow from Boars makes kiting Ursa very easy.


 * After, Wraith King rarely gets to do much as will stop any getaways and  will let Beastmaster's team quickly kill him a second time.

Others

 * Generally, any carry that is highly dependent on can be countered with.

Works well with...

 * Lifestealer can the Hawk or the Boar.


 * Beastmaster's Hawk gives vision over faraway enemies, letting Spirit Breaker target them with.


 * gives Sven some much needed attack speed.


 * Tinker can use to teleport to Hawks and Boars, allowing him to split push and gank.


 * makes up for Tiny's very low attack speed, allowing him to destroy buildings in no time.


 * Beastmaster's Hawk is a good scout for Roshan.
 * also benefits Ursa greatly.

Others

 * The long stun from gives certain heroes time to land difficult abilities:
 * 's
 * 's
 * 's
