Average Darius Card

When Average Darius Card enters the battlefield, tap two target creatures. On each upkeep, choose another target player. That player gains control of Average Darius Card.
On your end step, you gain control of all tapped creatures. For every creature you gain control of this way, a random player other than yourself gains control of a creature you control.
Whenever a player draws a card, sacrifice a creature. If you are unable to sacrifice a creature, you draw a card and lose 2 life.
