How to counter Marci in Dota 2

Marci grabs an allied or enemy target and throws it effortlessly behind her, damaging and slowing the unit if it's an enemy. Any enemy units in the landing area will also be damaged and slowed.

Marci bounds to the targeted allied unit, choosing a direction and distance she will spring away from it. Upon reaching the unit, Marci lunges to her final destination, damaging and stunning enemies where she lands. When Rebound is set to alt-cast, Marci brings the target ally with her to her final destination. The ally receives 15% bonus movement speed for 4s.

Passively grants Marci lifesteal and bonus attack damage. When cast on an ally, she provides them with 75% of her passive lifesteal and attack damage bonus. Additionally Marci creates a shared all damage barrier for herself and her partner. As Marci attacks heroes, 30% of the damage dealt restores the barrier.

Marci whistles to instantly summon her courier to her. If the courier started in the fountain, it will take items from Marci's stash. After teleporting it will transfer these items to Marci and head back to the fountain. Passively grants all allied couriers 3 bonus levels and 1 bonus health.

Marci taps a hidden power, gaining Fury charges that allow her to deliver a rapid sequence of strikes that slow movement and attack speed of the target for 2s. The last strike in every Fury combo creates a damaging pulse around the target. In between Fury combos, Marci is unable to attack for 1.5s. Marci gains 15% movement speed when Unleash is cast.
