Is Kaiu Gorobei targeting restriction set with the Fv of the discard?
Since Kaiu Gorobei targeting comes before the discard, I assume any targeting falls under the Good Faith rule, but if he discards a 2 Fv, can the Strategy "]Final Sacrifice" be used to redirect Kaiu Gorobei' action to 3F yojimbo?

What's your basis for stating that? The discard is the first thing that occurs in the action's resolution, per IvE MRP
