These two champions both counter each other in different ways. Kinessa can deal killing blows to Skye, while Skye can escape Kinessa's line of sight and easily murder her. When playing as Kinessa, put as much distance from yourself and Skye.
When facing Skye be sure to always have a mine near you in order to slow her and allow you to escape, also from longrange you can easily disable her with your damage by using the card which reveal your target for a certain duration in your loadout.
Skye effectively counters Kinessa, as first, Kinessa doesn't have any reliable movement strategy, and she cannot self heal. Additionally, Skye can evade Kinessa's shots, unless by some bad luck, gets hit by Kinessa, which means Skye can get close.
