Riders of the Apocolypse

When Riders of the Apocalypse enters the battlefield, if it's not a token, copy it for each of your opponents.
At the beginning of your upkeep, you may pay 1 life. If you don't, sacrifice a non-demon creature.
"And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with
him." -Revelations 6:8
