Hezera's Devoted

Flying
As long as you control a legendary creature called Hezera, The Dissenter, this creature gets +2/+2,
and opponents discard a card, lose 2 life, and sacrifice 3 creatures.
"Hezera sees the truth: The angels and demons must
both be utterly vanquished and be reborn into perfected
beings. It is the will of the Omnipotent Ones,
so shall it be."
