If you see Evie uses Ice Block and stays in it to heal, Charge your shot and aim for the head. there is a small window where Evie can't take action after Ice Block and you can one shot her as she comes out.
Avoid Ulting Zhin as his counter will waste it and heal him depending on the cards in his Loadout.
If you must Ult him, do it right after you see him finish using counter so he cant block it. He can still billow but he wont kill you or heal from it.
If you can see and kill Ying, Prioritize her over her Illusions. Killing Ying makes her Illusions despawn and prevents her from Healing/Shattering. If you can't see Ying and have no/low cauterize killing Illusions might stop healing from her.
