Instant — Trap
If
a
creature
spell
you
cast
this
turn
was
countered
by
a
spell
or
ability
an
opponent
controlled,
you
may
pay
rather
than
pay
this
spell's
mana
cost.
Look
at
the
top
seven
cards
of
your
library.
You
may
put
a
creature
card
from
among
them
onto
the
battlefield.
Put
the
rest
on
the
bottom
of
your
library
in
any
order.
