Zelvaus, Necrotic Illusion

When a creature you own is put into the graveyard from anywhere, create a token that's
a copy of target creature but it's a 1/1 and it's
an illusion in addition to its other types.

{4}{p/b}{p/u}: Search your library for a creature card, put it into the graveyard, then shuffle your library.
