If an enemy Skye uses her Smokescreen to escape nearby, you can use your abilities to trap the Skye by dropping your Warder's Field and Impasse in the nearest available exits. She can then be quickly bursted down in a 1v1 situation.
Mainly when going up against Skye, you'll be already halfway below health because she has surprised you. In that case use Withdrawal to counter. If you feel like you're ready, or Skye is about to disappear, use Planted to shred her down.
Stay far away from him as upclose he will wreck you, keep your distance from lex to avoid him detecting you and ruin your escape. (picking movement speed to do so is a good choice)
