I give it 2-5 pulls.
I have even tempted fate by tricking a spectral town guard of a ghost city into pulling a card. They pulled the Skull card.
Suddenly the group of living adventurers wandering around a mostly hostile ghost town looting and looking for the McGuffin became much easier.
I have a question though? What happens if a familiar draws the sun card "Grants 50k xp and a wondrous item?"
Does nothing happen?
Does the Wizard master get it?
Does it get class levels?
Does it become a class leveled and become a Cohort?
The wizard is level 4 and the familiar grabbed from the deck on its own.
