Rocks

Sacrifice Rocks, when you do, exile it. Search the
top 3 cards of your library, choose one land,
artifact or spell, put that card into your hand and
the rest to the bottom of the library. If you
placed a card into your hand with this ability,
create a 0/1 blue Legendary zombie named
Holemhelz with indestructible, shroud, and
the text "This creature cannot attack or block"
under your control.
