Melantha, Umbrus Raven

Flash, skulk, protection from instants
Sorcery spells you cast have cipher.
Whenever Melantha deals damage to a player,
you may cast a sorcery spell from exile with
encode or sorcery card from a graveyard this
turn. You can't encode on a creature that is
already encoded with the same card name.
During your end phase, create 2/2 blue bird with flying for each spell you cast this turn.
