Precious, Dhumm's Warhound

If both Precious, Dhumm's Warhound and
Beatrice, Dhumm's Warhound are on the
battlefield, graveyard, or if one is on the
battlefield and one is in the graveyard, search
your hand, graveyard, and library for a card
named Dhumm, the Skeletal Reaper and put it
onto the battlefield under your control.
Skeleton Horde (May cast this from the
graveyard, with Flash, if a skeleton creature
died this turn.)
