Instant — Trap
If
an
opponent
cast
a
red
instant
or
sorcery
spell
this
turn,
you
may
pay
rather
than
pay
this
spell's
mana
cost.
Prevent
the
next
3
damage
that
a
source
of
your
choice
would
deal
to
you
and/or
permanents
you
control
this
turn.
If
damage
is
prevented
this
way,
Refraction
Trap
deals
that
much
damage
to
any
target.
