As a kadita pro, Ican say that this hero have many combo styles. the new ult makes 3- petrify -1-2 combo doable. u can make use of the new ult waves combo. flicker-ult also a viable combo too
1-petrfy-2-3 Reason:some time you get stun before the (2)skill knock the enemy airborn so if you used petrfy before 2 skill he cant unterrupt you and you will get an easy kill
