Death of the Endless

Endless (If an Endless would be put into the
graveyard from anywhere, return it to the battlefield
tapped at the beginning of your next upkeep.)
At the beginning of each players end-step that
player sacrifices a permanent. Then if there are
no permanents in play other than Death of the
Endless you win the game.
