Yasuki Kojiro

Kojiro is Cavalry if you have one or more Ports in play. May remain bowed.
Open: Bow Kojiro to give the Cavalry trait to a number of cards you control equal to the number of unbowed Ports you have in play.
Limited: Bow Kojiro to blockade any Port in play. The Port is removed from play and has no effect on any cards in play. When Kojiro straightens or is destroyed, the Port returns to play, bowed.
