Goblin Wizardry

When Goblin Wizardry enters, exile target nonlegendary permanent an opponent controls for
as long as Goblin Wizardry is on the battlefield.

When Goblin Wizardry leaves the battlefield, the
owner of the permanent exiled with Goblin
Wizardry may cast it without paying its mana cost
and it gains demonstrate. (When you cast that spell,
you may copy it. If you do, choose an opponent to
also copy it. A copy of a permanent spell becomes a
token.)
