rules card - corrupting

to corrupt X, put X +1/+1 counters on target creature, and it perpetually gains corrupted. a corrupted creature is treated as a black cultist creature, and loses all other colours and creature class types (Ex. bard, warrior, artificer, wizard, etc.), but not any creature race types (Ex. kor, human, phyrexian, dog, dinosaur, etc.). You may only target a tempted creature with a corrupt ability.
