Plane — Tarkir
When
you
planeswalk
to
The
Great
Aerie
and
at
the
beginning
of
your
upkeep,
bolster
3.
(Choose
a
creature
with
the
least
toughness
among
creatures
you
control
and
put
three
+1/+1
counters
on
it.)
Whenever
chaos
ensues,
choose
up
to
one
target
creature
you
control
and
up
to
one
target
creature
an
opponent
controls.
Each
of
those
creatures
deals
damage
equal
to
its
toughness
to
the
other.
