When Evie leaves Ice Block, there's a brief moment where she vulnerable before she can Blink away. Time your Pounce and Daggers to finish Evie off if her HP is low, or for some parting damage if she has the Reprive legendary card.
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.
