Inverse Void Shredder

As long as Inverse Void Shredder is in play, you
may cast any spell that has been Exiled, or in a
Sidebar, or removed from the game without
paying its mana cost, except that it's a copy.
Copy fee- {3}: Create a token copy of the original
spell and any permanent is placed on the
battlefield under your control.
