To win against zhin, you need better position(high place) and good eye. Look at zhin loadouts first. Dont attack when zhin use counter. Fighting zhin is similiar like fighting koga, both are confusing. But in reality is not, as long you watch zhin.
Try to do a dubble jump, pounce upwards, tripple jump, nine lives, punce, quad jump combo. Hit ur daggers and win the 1v1, unless its hitscan or a counter. If that play safe. If the enemy is spread out or someone is low, try to outflank the enemy.
Evie's ultimate slows and cripples enemies, soar towards the enemy's spawn and try to catch their tanks and healers in the Ice Storm, it can seriously delay them and give your team precious seconds to secure the objective!
