Hextus, Inquisitor of Cavallia

Haste, First Strike
When Hextus, Inquisitor of Cavallia enters the
field, choose a color. When Hextus, Inquisitor
of Cavallia fights a creature of that color, she
loses First Strike and gains Double Strike.
Creatures of the chosen color that are destroyed
by Hextus, Inquisitor of Cavallia are exiled instead
of being sent to the graveyard.
