Ancient Star

Creatures with grasp counters on them don't
untap during their controller's untap steps.
When Ancient Star blocks a creature, tap that creature and put a grasp counter on it.
{t}: put a grasp counter on each creature with a
grasp counter on it. Ancient Star deals damage
to each creature equal to the amount of grasp counters on that creature.
{1}: remove a grasp counter from target creature.
Any player may activate this ability.
