Sorcery
Until
end
of
turn,
creatures
you
control
gain
menace
and
"Whenever
this
creature
deals
combat
damage
to
a
player,
exile
the
top
card
of
that
player's
library
face
down.
You
may
look
at
and
play
that
card
for
as
long
as
it
remains
exiled,
and
you
may
spend
mana
as
though
it
were
mana
of
any
color
to
cast
that
spell."
