Sorcery
Exile
the
top
X
cards
of
your
library.
You
may
cast
an
instant
or
sorcery
spell
with
mana
value
X
or
less
from
among
them
without
paying
its
mana
cost.
Then
put
the
exiled
instant
and
sorcery
cards
that
weren't
cast
this
way
into
your
hand
and
the
rest
on
the
bottom
of
your
library
in
a
random
order.
