Magical Hats

If target wizard you control would become target of a
spell, exile it, them put it face-down onto the
battlefield along with three magical hat artifact tokens
that say "Whenever Magical Hat is turned face up,
sacrifice it". The opponent chooses one of the four
facedown cards as the new target of the spell.

Then, turn the targeted card face-up. If the target wizard
is revealed, apply the spell's effect as normal.

You can turn the wizard face-up at any moment you
could cast a sorcery.
