Psijic Mimicry

The next time a creature would enter the battlefield, create a copy of that creature under
your control.
Circulate {u}{u} (If you cast this card from your
hand, exile it as it resolves. At the beginning of the
next upkeep, target opponent may pay {u}{u}. If they
do, they create a copy of Psijic Mimicry and may
choose new targets for the copy.)
