Aurelia, Resolute Sentinel

Flying, vigilance
Whenever a creature you control with a +1/+1
counter on it dies, you may exile it. If you do,
create a token that's a copy of that creature,
except it's a Spirit Angel with flying and
vigilance.
{2}{w}{u}{g}: Populate. Activate this ability only if
you control a creature with a +1/+1 counter on
it.
