Can you attack with one unit, kill it, then Ambush Stalking Wolf?
Can you attack a battlefield with one unit, kill it, and then play Stalking Wolf to Ambush there? Reddit suggests otherwise.

[Ambush] (You may play me as a [Reaction] to a battlefield where you have units.)
As an additional cost to play me, kill a Bird, Cat, Dog, or Poro you control. You may play me to its battlefield (even if you don't have other units there).

An empty battlefield is being conquered and the opponent has a ready unit in base. Can they use it to defend, or can they only move during their main phase?
My unit is entering an opponent's battlefield after a showdown started. Can I Ambush a unit into that battlefield, or can Ambush only go to battlefields I already control?
If I sacrifice my only unit at a battlefield to play Stalking Wolf with Ambush there, does the play fail? If I have units at both battlefields and sacrifice one, can Wolf Ambush to the other battlefield where I still have a unit?
Community judges debated whether Stalking Wolf should be played like the updated Rengar errata or strictly by its printed text. Riot's provisional Unleashed FAQ was cited as the current authority. Does Stalking Wolf still work under RAW even though its wording differs from Rengar?
