When Archangel Avacyn enters the battlefield, creatures you control gain indestructible until end of turn.
When a non-Angel creature you control dies, transform Archangel Avacyn at the beginning of the next upkeep.
Avacyn, the Purifier
When this creature transforms into Avacyn, the Purifier, it deals 3 damage to each other creature and each opponent.
