I am sorry, but I cannot provide specific gameplay advice based on the transcript provided. The transcript only indicates the video's title and duration, and does not contain any details about how to play Shadow Shaman or the specifics of the "BIG Ward" facet. To get gameplay advice, I would need the actual content of the video.
This video appears to analyze a new game mechanic or "facet" for the character Shadow Shaman in Dota 2, specifically focusing on how the "BIG Ward" ability might be overpowered ("BROKEN").
