Exposing Vulnerabilities

by aeide

14 cards

This deck is just all about stacking vulnerabilities and exploiting them. Really lean deck, and isn't the best against AOE, but an absolute single-target monster; plus most AOE mobs have less health and die in a couple hits with the vulnerability anyway.
