Andromeda, The Outsider

{r}{b}{ut} - Place a boast counter on target creature.
Use only as a sorcery.
Each creature with a boast counter on it deals
damage to its controller equal to its CMC on its
controller's end step. Boast counters are removed
from a creature when it attacks Andromeda's
controller.
