Just name out the Hero + combo you prefer.

Recently i trying out different combo with my fellow teammate just to harass opponent.

Below are my combo always use.

1. Dark Seer + Juggernaut
Casting ion shell + surge on Juggernaut with blade fury able to kill enemy non stop almost when they cant cast skill on you and have to run away, late game even chase enemy away and cast omnislash.
Also work best with a stun.
