When playing Exodus with the Sympathizer card in the Loyalty Deck (not using alternative loyalty cards), players who are executed before the sleeper phase draw a card from the Loyalty Deck, and so might draw the sympathizer card earlier than in the core game. Is this revealed right away, or can the person wait "unrevealed" until the sleeper phase? The card SAYS to reveal it immediately, but that was written when it was supposed to be a sleeper phase reveal, not earlier.
One way this has made a difference in our games is because we play a House Rule variant: Instead of the Sympathizer Card, we use the Sympathetic Cylon Card and instead of always getting a Sympathetic Agenda card, the player may get a Hostile Agenda card if the resources are all blue at sleeper phase and a Sympathetic Agenda if anything is in the red. Obviously, an early reveal means greater chance resources are still blue and the hostile agenda comes out but only because the reveal is early.
