Pizza Thief

A group of friends are attending the Fuzzballs Pizza Party and are going to try and predict how many pizza slices there will be at Party Time.

First some initial hidden value cards are played, then use your cards to either raise or lower your prediction, or play abilities that modify the pizza count or other predictions.
Each action card will tick the clock closer to Party Time, at which point the player who has the closest prediction is declared the winner.
