The Paths of the Dead

As the Paths of the Dead enters the battlefield,
choose a creature type.
{t}: Add {c}.
{t}: Add one mana of any color. Spend this
mana only to cast a creature spell of the
chosen type, and that spell can't be countered.
"The way is shut. It was made by those who are
Dead, and the Dead keep it, until the time comes."
