Corsair
[F7] The pirate rook must be the color that the icon specifies, and it must be on the card's sea border.
Move a pirate rook from a sea border to another sea border in the same location or to an adjacent location
that shares a sea border.
It may not move to a border occupied by a Pirate of the same color.
It kills any concession or opposing pirate at its new border at no cost.
