A player, 8 July 2007
If another player targets a Courtier in a discard pile (dead or otherwise) with an action (but does not target any Courtiers in play)...
Can a player react with Share the Blame? If so, is the dead/discarded courtier dishonored?
Political Reaction: After another player targets a Courtier with an action, dishonor one of your Courtiers: Dishonor the Courtier the other player targeted. You, then the other player, each lose 3 Honor.

If another player targets a Courtier in a discard pile (dead or otherwise) with an action (but does not target any Courtiers in play), can a player react with Share the Blame?
Most actions cannot target things out of play, so that would be rare.
If so, is the dead/discarded courtier dishonored?
Rules: "Effects only apply to cards that are either in play(.)" No.
