Unless your Champion's basic attack is hitscan, like Viktor or Tyra, you'll be hard-pressed to hit Androxus while he's airborne. Wait for him to land, if you can.
This matchup is one of the harder ones for Skye. Try to move in after Jenos uses Void Grip. Skye's strength is mobility, and Void Grip takes that strength away from her (Albeit temporarily).
Zhin is annoyingly good at surviving fights using Counter and Billow. But keep in mind that while using his abilities he isn't a threat but a DISTRACTION. Just live him be and focus on an other enemy while you waith for his ability to expire
