Khepri's Gilded Brooch

{3}, {t}: Search your library for a creature card
with eternalize or embalm, put that card into
your hand or graveyard, then shuffle your library.

a 1/1 black Insect artifact creature token with "Sacrifice this creature: Add one mana of any color. Spend this mana only to activate eternalize or embalm abilities."
