Merielle's Plague Curse

As this enchantment enters the battlefield,
sacrifice it and create a number of Enchantment
Aura Curse tokens equal to the number of
opponents you have. Each token gains: "When
a permanent enchanted player controls that is
enchanted with an Aura you control dies, exile
that Aura. When enchanted opponent looses
the game, exile all Auras you control on
enchanted player's board. On the next end step,
return all Auras exiled by this token to the
battlefield under your control."
