Curse of Disturbance (C17)

Enchantment — Aura Curse

Enchant player
Whenever enchanted player is attacked, create a 2/2 black Zombie creature token. Each opponent attacking that player does the same.

Sounds of life beckon many a restless soul.

Each Curse’s ability triggers only once, no matter how many creatures are attacking the enchanted player.
2017-08-25:
A player is attacking another player if they control a creature that’s attacking that player. If no creatures are attacking the enchanted player as a Curse’s ability resolves (most likely because they’ve left the battlefield), only the Curse’s controller performs its actions.

The triggered ability of these Curses won’t trigger if only a planeswalker controlled by the enchanted player is attacked.

If you enchant yourself with one of these Curses, you’ll get its effects whenever another player attacks you.
