Just had an idea. So we had a Zendo thread before; using rules that refer to words or text. So how about we have rules that categorize Dominion cards? Rules will define whether or not a Dominion card has Buddha-nature. Copied from Axxle's post:
This post is mostly copied from mafiascum:
http://forum.mafiascum.net/viewtopic.php?f=10&t=23946Those of you familiar with both Twenty Questions and Zendo already know the rules. For everyone else, let me break it down.
Each round, there is one Oracle and a flock of Petitioners.
At the beginning of the round, the Oracle invents a secret rule, completely mechanical, based on some property of Dominion cards. (Example: "Non-terminal actions have Buddha-nature). This rule will, given the name of a Dominion card (or Event), tell the Oracle to reply either "Yes" or "No". You must be able to answer the same question the same way, regardless of the context of the question.
During the round, any Petitioner (i.e. anyone other than the Oracle) may either name a Dominion card, or attempt to guess the rule. Each question asked shall be answered in order by the Oracle, according to the rule. Guesses the Oracle shall deal with in one of exactly two ways:
By conceding, and revealing the rule that had been used.
By replying with a question whose answer is different under the actual rule than according to the guess.
For example: if the rule is "cards costing $3 = yes" and someone guesses "cards whose name begins with w = yes, the Oracle might say, "Scheme."
The Oracle shall include in each post answering questions and responding to guesses a list of all prior questions, answers, guesses, and responses.
If the Oracle takes longer than 72 hours to answer a question, the Oracle shall forfeit. If no Petitioners have submitted questions or guesses for 96 hours, then any Petitioner may ask the Oracle to reveal the rule and step down.
The Petitioner who first guesses correctly shall become the next Oracle. If there is no such petitioner (such as after an Oracle is forced to forfeit) [edit: or if said petitioner does not choose a rule within a reasonable timespan], the first poster to so choose may become the next Oracle.
