Final chaotic end

This spell cannot be counterd

Pick a random opponent

Flip a coin. If you win the flip, you gain 1 life and target opponent loses 1 life. If you lose the flip, you lose 1 life and that opponent gains 1 life. Flip again
and double the life stakes with each flip.
Any player with 0 or less life loses the game
The winner repeats this effect with another random opponent if possible
