A question came up about the timing on Shadow Politics during a game this week:
when can I use the effect of SP to initiate an Intrigue challenge?
What happened was that a player (who was not the first player) played SP. He then proceeded to immediately attempt the challenge, which I said he could not, but had to wait until it was his turn to initiate challenges. My rationale was that, at any point during the Challenges phase, only the active player may initiate challenges, and that the text on SP does not contradict this ("as a standard action" merely provides for challenges outside of the Challenges phase).
What should be the way to resolve this?
What about during the Marshaling phase? Can a non-active player initiate the challenge provided by SP?
