Enchantment
Whenever
one
or
more
creatures
you
control
deal
combat
damage
to
a
player,
you
may
sacrifice
one
of
them.
If
you
do,
reveal
cards
from
the
top
of
your
library
until
you
reveal
a
creature
card
that
shares
a
creature
type
with
the
sacrificed
creature.
Put
that
card
onto
the
battlefield
and
the
rest
on
the
bottom
of
your
library
in
a
random
order.
