Legendary Creature — Aetherborn Rogue
Whenever
a
player
casts
a
spell
they
don't
own,
that
player
creates
a
Treasure
token.
Whenever
a
creature
deals
combat
damage
to
one
of
your
opponents,
its
controller
looks
at
the
top
card
of
that
opponent's
library
and
exiles
it
face
down.
They
may
play
that
card
for
as
long
as
it
remains
exiled.
Mana
of
any
type
can
be
spent
to
cast
a
spell
this
way.
