Malicious Mists

—Madness {x}{x}{x}{b}{b}{b}
When you cast Malicious Mists, each player
dooms X+3 permanents they own.
Whenever a player attacks, each player sacrifices
a permanent. If a doomed permanent is
sacrificed this way, its owner loses 9 life unless
they doom two permanents they own.
If there are no doomed permanents, exile
Malicious Mists and you lose 9 life.
