Kaecilius (Unmerciful)

Strategy
Powers that create enemy strike tiles are useful against him. e.g. Elektra's Double Double Cross, 's two active powers, Sabretooth's Happy Birthday, Runt.

Powers that let you move tiles are useful to match Kaecilius' Stike tiles. e.g. Quicksilver's Idle Hands, Bullseye (Classic)'s Deadly Precision.
