Aethiya, God of Ascension

Flying, Indestructible
Aethiya isn't a creature if your devotion to
Humans and Angels is less than 5.
All Humans you control have Ascension.
(Whenever this creature deals combat damage you
may pay {3}{r}{r}{r}, if you do, exile it. At the
beginning your next upkeep, return it to the battlefield
with 5 +1/+1 counters on it. It becomes an Angel,
gains flying and loses all other types.)
