Add a new subrule “Spies {I}” to “Teams and Targets {I}”:

Each Mastermind may have a Spy, who (if present) is a Participant or Idle Participant tracked privately by that Mastermind. By default, Masterminds have no Spy. When a Mastermind’s Target is removed, this also removes their Spy.

If all Participants have a Target, and there are at least three more non-Mastermind Participants on opposite teams from a particular Mastermind than on the same team, that Mastermind can perform the following atomic action (unless they already have a Spy): secretly randomly select a Participant on the opposite team, gain that Participant as a Spy, and privately inform that Participant that they are that Mastermind’s Spy.

When a Participant who is a Mastermind’s Spy gains Triumphs, either that Spy or that Mastermind must reduce that Spy’s Triumphs by twice the amount gained, to a minimum of 0. (Neither can take other dynastic actions until this action is performed.) The Mastermind may reveal the identity of the Spy when performing this action.

When a Participant ceases to be a Mastermind’s Spy (due to that Mastermind losing their Target), if that former Spy did not gain Triumphs as part of the same action that caused them to cease to be a Spy, that former Spy can once within 48 hours increase their Triumphs by 2.

In the text “Benevolent Dictators” added to the ruleset (if present), change “same team” to “same team (except Spies)” and “opposite team” to “opposite team (except Spies)”.
