That approach works well for a game like [Codewords](https://en.wikipedia.org/wiki/Codenames_(board_game)) where you're trying to find a single-word common hint between many of your words (that doesn't hit any of the other words).

My feeling is that it'll struggle with word-plays in OnlyConnect/Connections (like missing letters, added letters, words-within-words homophones, etc) as well as two-step references (such as {Venice, Dream, Night, Nothing} => "last words of Shakespeare plays"}).
