Ranshi and Corwinnn

When Ranshi and Corwinnn, Untamed enters
the battlefield, create a number of colorless land
tokens with "{t}: Add {u}, {r} or {g}" equal to the
number of mana spent to cast Ranshi and
Corwinnn minus the number of nontoken lands
you control.
Whenever you cast an instant or sorcery spell, if
it was cast using no mana from nontoken lands,
copy it. You may choose new targets for the copy.
