Hidden agenda (Start the game with this conspiracy
face down in the command zone and secretly name
a card. You may turn this conspiracy face up
any time and reveal the chosen name.)
When you select a card also select one color on
that card and replace all pips of the chosen color
with another color. The chosen card is no longer
the original color but is the new color in addition
to its other colors. All colors must be named
before the start of the game.
