Enchantment
Whenever
a
creature
you
control
attacks,
it
phases
out
at
end
of
combat.
(While
it's
phased
out,
it's
treated
as
though
it
doesn't
exist.
It
phases
in
before
you
untap
during
your
next
untap
step.)
"I don't like to speak ill of 'walkers . . . but just what did Teferi think he was doing?"
