Galrodd, Infernal Dragonlord

Flying
Galrodd cannot be sacrificed.
At the beginning of your upkeep, each player sacrifices a non-legendary creature.
Whenever Galrodd deals combat damage to a
player, each player sacrifices a legendary creature.
Then each player loses life equal to the total converted mana cost of creatures sacrificed
in this way.
"Your flesh will serve wondrously as fuel for my all
consuming flame."
