Can I Ambush Kha'Zix before my opponent Ambushes in response to my move?
I move into a battlefield where my opponent has one unit and Ambush Kha'Zix for the one-on-one bonus. They claim they can Ambush orange Rengar on my first unit before Kha'Zix enters. Who gets to play first, and when is Kha'Zix's condition checked?
