Enchant Creature

At the beginning of the upkeep of enchanted creature’s controller, put a -1/-1 counter on that creature.

At the end of any player's turn, if a player has less life than any other, that player gains control of enchanted creature.

I don't see the point of the two abilities?  Is it trying to set up a Pulse of the Forge/Fields type life bidding war?  Because that doesn't come through well with the ability.  I'd rather see it make the creature bigger so if the opponent gets hit with it they are more likely to give it back.  Or even more directly, just make it have to target an opponent's man, and swap control when they get hit with it (and make it bigger).
