Grasho Kal, Unspoken Voice

Flash
When you cast Grasho Kal, return target
creature with converted mana cost X to its
owner's hand where X is the amount of {u}
spent to cast it. Grasho Kal enters the battlefield
with a +1/+1 counter on it for each {g} spent
to cast it.
The call of a child. The song of a bird. A flash of
fangs. A life undone.
