The only attacks Zhin's Counter Stance CANNOT counter is Jenos' Ultimate. Other than that it can counter literally any attack

To take down evie you need to be grouped up and overwhelm her. But if you are jenos dont void grip her just yet. Wait for her to overwhelmed and use ice block first. Then use void grip just when she's about to come out to take her down

If an androxus attempts reversal don't go to counter stance instead just wait a small second and then whirl and go behind him. Whirling will surely damage him no matter what and then suddenly being behind will surprise him and allow you to takedown

From distance Jenos can't do much damage but he has cards that reveals enemies shot by him for a short duration. That's not all, at close range his Void Grip ability can grip even stealthed enemies
