When this creature enters, you may have your life total become the total toughness of creatures you control. {5}{W}: This creature gets +X/+X until end of turn, where X is your life total.
At the beginning of your upkeep, the player with the lowest life total gains control of this creature. If two or more players are tied for lowest life total, you choose one of them, and that player gains control of this creature.
Sacrifice this creature: Return target legendary creature card from your graveyard to the battlefield. Activate only during your turn, before attackers are declared.
