Dissection Protocol

Imprint — When Dissection Protocol enters
the battlefield, incubate X. Then you may
exile up to one target nontoken creature. If
you do, Dissection Protocol becomes an Aura
with enchant token and "As long as enchanted
permanent is a creature, it's a copy of the exiled
card, except it's a 0/0 colorless Phyrexian
artifact in addition to its other types." Attach Dissection Protocol to the token.
