Ar-Pharazôn, the Golden

At the beginning of your upkeep, each opponent
loses 1 life, then you gain 1 life.
Whenever a non-token creature is sacrificed, you
may pay {1}. If you do, create a treasure token.
(It's an artifact with "{t}, Sacrifice this artifact:
Add one mana of any color.")
"Tar-Calion he was first named, the last and greatest
of the Kings of Numenor. But his is a legacy of death,
destruction, and downfall."
