Evie is easy to counter if u know where she is blinking from (Wormhole). With cat burgular u can burst her down. When she aproach u, dont use prowl. Just throw some daggers at her. When she blinks back, pounce to her location and use prowl damgboost
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.
