A player, 2 January 2013
I know the answer, just need to make sure it's here for reference in case
Situation:
I have Doji Bob and Doji Jim at home. I attempt to Brave New World Doji Bob into a battlefield, and my opponent reacts with Request Authorisation. Can I redirect the target of Request Authorisation using Ryoshun's Guidance to Doji Jim, and have Bob move normally?
Card texts:
Reaction: Before another player's Battle action resolves, target a Personality: Negate his movement to the current battlefield from the action's effects.
Reaction: When another player's action would target one of your cards, discard this card: Choose another of your non-Stronghold cards at the same location. The action targets it instead, if legal.

That works.
