Hedonic Treadmill

As Gambling Addiction enters the battlefield,
you lose life equal to your life total.
You don't lose the game for having 0 or less life.
If you would gain life, take a card from the Ante instead and put it in your hand.
Whenever you're dealt damage, add that many nontoken permanents you own and control to the
ante. If you can't, you lose the game.
Gambling releases dopamine, which is the basic brain chemical at the root of addiction.
