A player, 17 June 2012
Greetings, My opponent is about to gain Honor from an action effect during my turn. I'm reacting with Rhetoric to steal his gain. Can I then react with Destructive Priorities to make my opponent lose Honor instead?
Rhetoric Political Reaction: Before a player gains or loses Honor from an action's effects, bow your performing Courtier: Choose another player. If the Courtier's Chi is higher than or equal to the Honor gain or loss, the chosen player instead of the original player takes the gain or loss
Destructive Priorities Kata • Political You have the ability, "Political Reaction: Before you gain Honor during your turn, bow your performing Courtier: Negate the gain. Choose a player. He loses 2 Honor."

Rhetoric Political Reaction: Before a player gains or loses Honor from an action's effects, bow your performing Courtier: Choose another player. If the Courtier's Chi is higher than or equal to the Honor gain or loss, the chosen player instead of the original player takes the gain or loss
Destructive Priorities Kata • Political You have the ability, "Political Reaction: Before you gain Honor during your turn, bow your performing Courtier: Negate the gain. Choose a player. He loses 2 Honor."
Yes. Both Rhetoric and Destructive Priorities have (essentially) the same trigger, "Before a player gains honor."
You will be able to react with Rhetoric, then your opponent may react to the same trigger or pass, then you get another opportunity to react to the same trigger with your Destructive Priorities.
