I'm still waiting for them to make a "when you have 0 or less life, you win the game instead" card haha
Can't see it happening. They'd have to make it so expensive or design it in such a way that it wouldn't ruin competitive formats (so it'd likely not see any play), and then in casual it'd run the risk of just stopping any deck that doesn't have suitable removal. Oh sorry, you're playing monogreen ramp+stomp? You just can't win against my win-at-0 card.
You can't just have fun at the expense of power balance.
