This card has an unexpected synergy for an investigator who came out years earlier. Jim Culver, musician, can use this spell to great effect. His power lets him to treat the elder sign as a skull, and skulls as +0. But that’s different than the token.
So when Jim puts Flame into play, he’s only afraid if he draws an actual zero (on hard or expert, there aren’t any +1s in the bag.)
This makes it much better for him than shriveling, which can trigger off during a skull token even if it counts as a zero.
