Master of the Rolling River: Kiho Water Battle: Bow one of your target Shugenja or Monks at any location: Move one of your target units at a battlefield to a different battlefield.
May I attack province A, resolve province B first (with no presence), and play Master of the Rolling River to move my personality from province A to province B?
Thank you.
