I have been using this card more and more, but not as mentioned by the other comment, to dodge monsters, but rather to... attract them. A kind of On the Hunt (3).
Both William Yorick and Silas Marsh want to face enemies to take the best out of their Decks. In Yorick especially, the more enemies, the more shenanigans you can do and this card basically double the chances to find an enemy when needed, while also helping you not to get too overwhelmed at some point.
