Peter, Fisher of Men

{u}{r}{x}{t}: Until the end of turn, whenever
you cast a non-legendary spell with a casting
cost of X or less, copy it. If it's an instant,
sorcery, or enchantment spell, you may select
new targets for the copy. If it's a creature or
artifact, you may create a token that's a copy of
that creature or artifact. If it's a planeswalker,
instead have it enter the battlefield with an
additional loyalty counter on it. Activate
only as a sorcery.
