Bodak

When Bodak is summoned, target a creature, the
player who controls the target creature must roll a
1D20 and add the converted mana cost onto the
number rolled. If the number rolled was bellow a
13 or bellow, destroy target creature.
Undead creatures devoid of personality or souls, bodaks
were cruel and relentless hunters, either of their own
volition or at the behest of some greater power.
