Phespia, Stonesight Gorgon

Whenever Phespia, Stonesight Gorgon deals
combat damage to a player, you may pay
{2}{b}, {2}{g} or {2}{u}. If you do, destroy target
creature permanent. It can't be regenerated, put
four +1/+1 counters on Phespia, Stonesight
Gorgon, or tap target creature an opponent
controls. That creature doesn't untap during
its controller's next untap step.
"Her gaze alone can turn flesh to stone, and stone to
dust." -- Daxos of Meletis
