Try to have max shield card. And HP regen around Teleport card to duel with recovery buck. You can duel with buck, and also you have escape option if buck about to kill you.
Max your shield. Place teleport first and try to track evie when she about to engage you. If she about to landing, then spam the landing place. And in duel 1v1 you need to jump or moving right left or both because she might miss her shot.
Koga can be so confusing. But in reality is not. Place your teleport first and Aslong you watch koga movement you can win the duel. Have max shield would give you time to read the situation first between fight koga or enter teleport
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.
