It is hard to scout Cana... Her magic is difficult to figure out. Though she seems to lack the offensive/defensive power matchup against Juvia, her cards allow her to be versatile and attack Juvia at an unorthodox manner... If Juvia forces Cana in a slugfest or a contest of raw power, then she wins. If Cana is able to drag the fight, she can force Juvia to make mistakes, and she wins.
