Diana Stanley deck only.
Fast. Play when an investigator at your location draws an encounter card or a weakness.
Cancel all of that card's effects and shuffle it back into its deck. (Do not draw a new card to replace it.)
I'm honestly just curious: does this card also cancel enemies? I've had fantastic success with it just cancelling weaknesses and treacheries, but I'm not sure how far its utility goes. Anyone out there know? I suspect it does since it otherwise has wording very similar to Ward of Protection (5)
